freedom-u-sdk

SiFive Freedom Unleashed SDK layer for OpenEmbedded/Yocto

Description

The experimental Freedom Unleashed (FU) SDK is based on OpenEmbedded/Yocto framework, allowing to build custom Linux distributions:

• build predefined disk images for QEMU, SiFive HiFive Unleashed development board and SiFive HiFive Unmatched
• build custom disk images with additional software packages from various third-party OE layers;
• quickly launch QEMU VM instance with your built disk image;
• build bootloader binaries (OpenSBI, U-Boot, U-Boot SPL);
• build Device Tree Binary (DTB);
• build Linux kernel images;
• easily modify disk partition layout.

For more information on particular release see ReleaseNotes directory in freedom-u-sdk repository on GitHub.

For advanced OE usage we advice to look into Yocto Project Documentation and A practical guide to BitBake.

Dependencies

This layer depends on:

• https://github.com/openembedded/bitbake
• https://github.com/openembedded/openembedded-core
• https://git.openembedded.org/meta-openembedded
• https://git.yoctoproject.org/meta-virtualization
• https://github.com/sifive/meta-sifive.git
• https://github.com/kraj/meta-clang.git
• https://github.com/NobuoTsukamoto/meta-tensorflow-lite.git

Prerequisites for the build host

• Yocto
• kas

Create the build environment

mkdir dist && cd dist
git clone https://github.com/sifive/freedom-u-sdk

Available machines

This layer doesn't define new machines. It uses machine provides by the meta-sifive layer, as well as the Qemu RISC-V provided by the oe-core layer.

Available distribution

This layer provides a distribution, named freedom-u-sdk for the following machines:

• freedom-u540: The SiFive HiFive Unleashed board,
• unmatched: The Sifive Unmatched board,
• qemuriscv64: The Qemu RISC-V 64bits.

It also provides two disk images:

• demo-coreip-cli: basic command line image (recommended);
• demo-coreip-xfce4: basic graphical disk image with Xfce 4 desktop environment.

Build images

Building disk images is CPU intensive, could require <10GB of sources downloaded over the Internet and <200GB of local storage.

This layer provides Kas scripts configured to download and to configure the build environment to build demo-coreip images for supported targets:

kas build --update ./freedom-u-sdk/scripts/kas/freedom-u540.yml
kas build --update ./freedom-u-sdk/scripts/kas/qemuriscv64.yml
kas build --update ./freedom-u-sdk/scripts/kas/unmatched.yml

Moreover, it is also possible to build other images, or SDK, or also packages, for example:

kas build --update ./freedom-u-sdk/scripts/kas/unmatched.yml --target core-image-weston
kas build --update ./freedom-u-sdk/scripts/kas/unmatched.yml --target buildtools-extended-tarball
kas build --update ./freedom-u-sdk/scripts/kas/unmatched.yml --target busybox
kas shell --update ./freedom-u-sdk/scripts/kas/unmatched.yml -c "bitbake core-image-minimal -c populate_sdk"
kas shell --update ./freedom-u-sdk/scripts/kas/unmatched.yml -c "bitbake core-image-minimal -c populate_sdk_ext"

Running in QEMU

The OpenEmbedded/Yocto framework provides a wrapper for QEMU, named runqemu in order to use it easily.

Below examples to use this Qemu over a Kas shell:

kas shell ./freedom-u-sdk/scripts/kas/qemuriscv64.yml -c "runqemu slirp nographic demo-coreip-cli"
kas shell ./freedom-u-sdk/scripts/kas/qemuriscv64.yml -c "runqemu slirp serialstdio demo-coreip-xfce4"

Execute runtime tests

The OpenEmbedded/Yocto framework provides also provides tools to implement and to run tests.

These tests can be executed on all supported targets, using the following commands:

kas build --update ./freedom-u-sdk/scripts/kas/qemuriscv64.yml:./freedom-u-sdk/scripts/kas/include/test.yml
kas shell --update ./freedom-u-sdk/scripts/kas/qemuriscv64.yml:./freedom-u-sdk/scripts/kas/include/test.yml -c "bitbake demo-coreip-cli -c populate_sdk && bitbake demo-coreip-cli -c testsdk"
kas shell --update ./freedom-u-sdk/scripts/kas/qemuriscv64.yml:./freedom-u-sdk/scripts/kas/include/test.yml -c "bitbake demo-coreip-cli -c populate_sdk_ext && bitbake demo-coreip-cli -c testsdkext"
kas shell --update ./freedom-u-sdk/scripts/kas/qemuriscv64.yml:./freedom-u-sdk/scripts/kas/include/test.yml -c "resulttool report  ./tmp/log/oeqa"

Running on Hardware

You will find all available build fragments (incl. disk images) in $BUILDDIR/tmp/deploy/images/$MACHINE where MACHINE can be:

• freedom-u540
• qemuriscv64
• unmatched

Disk images files use <image>-<machine>.<output_format> format, for example,

demo-coreip-cli-unmatched.rootfs.wic.xz. We are interested in .wic.xz disk images for writing to uSD card.

Be very careful while picking /dev/sdX device! Look at dmesg, lsblk, blkid, GNOME Disks, etc. before and after plugging in your uSD card to find a proper device. Double check it to avoid overwriting any of system disks/partitions!

Unmount any mounted partitions from uSD card before writing!

Flash the image on SDCard

Images built can be flashed with bmaptool (faster), for example:

sudo bmaptool copy ../build/tmp/deploy/images/unmatched/demo-coreip-xfce4-unmatched.rootfs.wic.xz /dev/mmcblk0

Otherwise, you can also use the dd command, for example:

xzcat ../build/tmp/deploy/images/unmatched/demo-coreip-xfce4-unmatched.rootfs.wic.xz | sudo dd of=/dev/mmcblk0 bs=512K iflag=fullblock oflag=direct conv=fsync status=progress

MSEL for Unleashed

You will need to modify MSEL to allow using U-Boot SPL, OpenSBI, U-Boot proper bootloaders from uSD card instead of SPI-NOR Flash chip:

      USB   LED    Mode Select                  Ethernet

MSEL for Unmatched

By default MSEL on Unmatched is set to use uSD instead of SPI-NOR Flash chip to load U-Boot SPL, OpenSBI and U-Boot proper. Below is the default configuration for DIP switches (located next to Assembly Number and RTC battery):

  +----------> CHIPIDSEL

BOOT MODE SEL

Connecting Using Serial Console

Connect your HiFive Unleashed or HiFive Unmatched to your PC using microUSB-USB cable to access serial console.

For macOS, run: screen -L /dev/tty.usbserial-*01 115200

For Linux, run: screen -L /dev/serial/by-id/usb-FTDI_Dual_RS232-HS-if01-port0 115200

The above commands might vary depending on your exact setup.

-L command will log all output to screenlog.0 in your current working directory.

To quit screen, hit Ctrl - A followed by \ symbol. Finally agree to terminate all windows by typing y.

You can login with root account. The password is sifive. We strongly recommend to change the default password for the root account on the first boot before you connect it to the Internet.

Connecting Using SSH

Before you connect your board to the Internet we strongly recommend to change the default password for the root account and configure your network equipment (for example, routers and firewalls) appropriately.

SSH daemon is enabled by default, in order to be able to execute remotely runtime tests. To disable SSH daemon connect to the board using serial console method described above. Once connected execute the following commands:

systemctl disable sshd.socket
systemctl stop sshd.socket

The HiFive Unleashed and Unmatched behave like any other network capable device (such as PC, laptop, and Single Board Computers like Raspberry Pi). Connect the board to your network (for example, a router), and it will acquire IPv4 + DNS configuration using DHCP protocol. You can use your router management panel to get assigned IPv4 address or use the serial console to acquire it directly from the board (use ip addr command to print active network information). Finally you can SSH to the board:

ssh -o PreferredAuthentications=password -o PubkeyAuthentication=no -o StrictHostKeyChecking=no -o "UserKnownHostsFile /dev/null" root@<IPv4>

Supported GPUs

Various GPUs from AMD were successfully tested with the boards. In particular Radeon HD 6450 is the most widely used. Other GPUs from the same family might also work, for instance, THD64xxM, HD7450, HD8450, R5 230, R5 235, R5 235X. The newest tested GPUs from AMD are RX 550, RX 570, RX 580 with no issues.

Online Resizing of rootfs (Root File Partition)

It is highly advised to resize partitions offline (i.e. before booting the system). If you already booted the system and cannot do offline resizing then the following instructions should resize rootfs (root file partition) to full uSD capacity:

sgdisk -v /dev/mmcblk0
sgdisk -e /dev/mmcblk0
parted /dev/mmcblk0 resizepart 4 100%
resize2fs /dev/mmcblk0p4
sync

NBD (Network Block Device) rootfs

This is an experimantal feature currently only available on SiFive HiFive Unmatched board. This allow sharing a block device over the network. This is not an extensive guide into NBD, but a quick start.

If you want to use this feature open extlinux.conf in /boot partition and modify the append line to:

append ip=dhcp root=/dev/nbd0 rw nbdroot=<server_ip_address>:<export_name> nbdport=10809 console=ttySIF0,115200 earlycon

If you are booting directly from U-Boot prompt, you would need to set bootargs variable instead.

Note that <export_name> value might be ignored by the NBD server (depends on the implementation and configuration).

nbdkit is a recommended NBD server for it's flexibility.

Here is an example command for nbdkit:

sudo nbdkit -f --verbose --threads 128 --filter=cow --filter=partition --filter=xz file demo-coreip-xfce4-unmatched-<..>.rootfs.wic.xz partition=4

This would expose the ext4 filesystem on the 4th partition from XZ compressed disk image. By default it's read-only thus we also add a COW (Copy-on-Write) layer. Note that COW layer is not saved by default and will be lost if nbdkit process is terminated. See nbdkit-cow-filter NOTES on how to save disk image with all the modifications for further use.

Using XZ compressed disk image is convenient, but doesn't deliver high performance. For higher performance uncompress disk image before sharing it via NBD.

Here is another example:

sudo mkdir rootfs
sudo tar -xJ --numeric-owner -C rootfs -f demo-coreip-xfce4-unmatched-<..>.rootfs.tar.xz
sudo nbdkit -f --verbose --threads 128 --filter=partition --filter=cow linuxdisk $PWD/rootfs size=+2G partition=1

In this particular case we uncompress rootfs into a directory. We ask nbdkit to take the directory, generate linux disk image from it, add some additional free space, add a COW layer to make it writable and send "naked" filesystem (i.e. no partition table) as before.

nbdkit has a number of plugins and filters allowing various ways how to share disk images over the network.

freedom-u-sdk's Issues

Priv-1.10 branch doesn't work with QEMU / Master's branch user/pass?

Everything built successfully on the priv-1.10 branch. The following is used to run qemu, but nothing happens.

qemu-system-riscv64 -kernel riscv-pk/bbl -initrd bbl.bin -nographic

The master branch boots with the same command, but what is the user/password? Users default nor root without a password work.

Running bbl image from freedom-u-sdk with fesvr

The Linux image generated from freedom-u-sdk tag hifiveu-0.0 runs nicely on spike with 4 cores, but I wasn't able to use the corresponding bbl image, which is also automatically generated, for booting Linux on top of a single-core Rocket Chip running on a ZC706.

In light of this, should I make any modification to the Kernel config or to any other tool to boot that same spike-working image on an FPGA?

I've already made sure that riscv-pk and riscv-fesvr are updated and that the /usr/local/lib path on the board holds the new version of libfesvr.so. Running $./riscv-fesvr pk hello on the board also works as intended.

Better error message if submodules don't exist

It would be nice if you happen to forget to check out the submodules to provide a more helpful error message.

Currently cloning the freedom-u-sdk with 'git clone https://github.com/sifive/freedom-u-sdk' and then running 'make' gives an error message like this:

freedom-u-sdk tmagik$ make
rm -rf /Users/tmagik/src/SiFive/freedom-u-sdk/work/buildroot_initramfs/

trap_illegal_instruction and trap_instruction_access_fault when running program

After running make and compiling some programs for RISCV and trying to run them, I get errors. When running these programs on the linux kernel through spike, I get the trap_illegal_instruction and trap_instruction_access_fault, and the programs stop working. I am running spike with -p2 processors.

The instructions that result in trap_illegal_instruction are:
csrr
fsd
fld

When the second core, core 1, starts running, it runs for a bit, then does the mret instruction, and immediately after this it gets stuck on the trap_instruction_access_fault exception. The full error is:
core 1: exception trap_instruction_access_fault, epc 0x0000000000000000
core 1: badaddr 0x0000000000000000

It continues like this until I CTRL+C.
Any ideas how to fix this? I would like to get some memory traces from a shared memory program, to be able to test a cache coherence protocol I am designing for a computer with a RISCV core.

buildroot compile failure on Debian Buster (testing)

I am having a problem building buildroot when running make qemu with top-of-tree on Debian Linux x86_64 (Note I have done unset RISCV so that I use the toolchain bundled with freedom-u-sdk):

The buildroot submodule in freedom-u-sdk points here: sifive/buildroot@dfc1531

The builtroot sifive branch points here: sifive/buildroot@9fa9c29

It seems e2fsprogs is not compiling due to a conflict between a unistd.h definition of copy_file_range and a statically defined version of copy_file_range in e2fsprogs-1.43.1/misc/create_inode.c

Okay. The error is buildroot trying to build a host e2fsprogs and it the conflict is with my debian system headers in /usr/include/unistd.h:1110

This is from this debian package which is from "buster" (Debian testing):

libc6-dev:amd64                           2.27-2 

Okay. Let's try a downgrade to "stretch" (Debian stable):

libc6-dev-i386                            2.24-11+deb9u3

We've downgraded the host compiler from gcc-7.3 (buster) to gcc-6.3 (stretch). More problems. Compiler doesn't support the Stack Smashing Protector:

SSP support not available in this toolchain, please disable BR2_TOOLCHAIN_EXTERNAL_HAS_SSP

Maybe I can modify one of these:

Am I missing something ? @jim-wilson @palmer-dabbelt
Google search results seems to indicate the above compilation errors are gcc related. However, I am not able to understand how switching linux kernel version affects this.

Compatible Rocket Chip Commit for Multicore?

Hi there,

I am starting to develop an accelerator for the Rocket Chip using its RoCC interface, but it has been a bit difficult to find a combination of versions for rocket-chip/riscv-tools/riscv-linux that works for multicore configurations of that SoC. On the other hand, the latest hifiveu-1.0-2018-03-20 release of this repository seems very promising.

That said, does anyone know a commit from Rocket Chip that is guaranteed to work with this latest release tag?

Besides, am I right to suppose that both the riscv-gnu-toolchain and riscv-linux repos here submoduled already target priv-1.10?

I would be immensely grateful for any help with this, as the process of checking out commits, configuring Linux, compiling everything, generating a bitstream and testing on the board does take some time x)

How to add files or directories into bbl.bin

Linux has run on my zc707 successfully, and I want to add files or directories in some subdirectories, such as /root.

When I modified the initramfs.txt in conf subdirectory, the bbl.bin got bigger. But I couldn't see my file in linux.

When I modified the initramfs.txt in linux/arch/riscv subdirectory and added its path through make linux-menuconfig, the bbl.bin remains invariant.

I don't know why.

I tried to modified buildroot, but don't konw how to do it.

Thanks for your help.

fopen returns errno 38

Hello,
I use the newest freedom-u-sdk, commit id: 97b2ca1, to run a binary contains fopen function. However, it returns errno 38, which is 'not implemented'. This exact same issue had been addressed in Issue #86 in riscv-linux sub-directory, but the problem seems to manifest again with the newest commit.

My freedom project commit id is 89059e7.
Thank you

udhcpc should try more than 3 attempts at boot

Slow switches suck. We need to bump this to at least 5 attempts to get a reliable IP on boot.

Failed to boot linux with master branch

I used to use no-pcie2 branch of freedom and hifive-unleashed branch of freedom-u-sdk when I didn't have a FMC card, and successfully boot linux in VC707. Now I get a FMC card and clone the master branch of freedom and freedom-u-sdk. Nothing goes wrong in compile process. But I didn't didn't see any output in minicom.

Build 32-bit target failed

Hi,

I am trying to build 32-bit target from freedom-u-sdk. The build of 64-bit target works well but the 32-bit failed. What I am doing is modifying the Makefile and changed the variables

ISA ?= rv32ima
ABI ?= ilp32

Then type make linux and I got no rule to make target error:

Please help to point out what I am doing wrong.

Thanks in advance,
Kai-Yuan

the bootloader runs, but fails to boot linux

@palmer-dabbelt @terpstra

Hello.

I can not boot because of the following reasons.
sifive/freedom#38

The source code was not booted for the same reason before it was updated.
Is the installation and setup wrong?

Below are the logs that created the bitstream and image file using freedom and freedom-u-sdk.

freedom(/master)

# make -f Makefile.u500vc707devkit verilog
# make -f Makefile.u500vc707devkit mcs

Bitstream generation succeeded (Vivado : 2016_01)

freedom-u-sdk(/master)

$ /freedom-u-sdk# cd riscv-gnu-toolchain
$ make & linux make
 -> Toolchain installation (7.2.0)
$ /freedom-u-sdk# make

Error: "unable to execute program：(abstractcs=0x10000301)" when use command "make run_openocd...."

Hi,all

When I use command "make run_openocd ........" to debug demo program encountered that error, how to fix ?

An error occurred in the new version using make all

I downloaded the latest version, did not change Makefile, and then I used make all to build it with the following errors.
It looks like the library file could not be found while compiling the linux kernel. Where is the path configuration error?
How do I fix it?


@jim-wilson Hi,jim.I need your help again,thank you.
And It's the new year in China now,happy new year to you.

how to use gdbserver in vc707

I want to debug my program with gdb in vc707. It seems I need to build a gdb in my host and a gdbserver on target board.
make buildroot-menuconfig in Toolchain , I selected Build cross gdb for the host (NEW) or Copy gdb server to the Target , but didn't see gdb or gdbserver generated. How should I do?

If I use the repository, riscv-binutils-gdb, how to generate riscv64 gdb and gdbserver ?

no console output after bootconsole disabled.

Just found that there is no output after bootconsole disabled by kernel.

Kernel fault when running bash/coreutils

We're trying to upgrade the rocket-chip version for firesim, but are having trouble running buildroot+linux. Everything seems to work fine if we use busybox for the shell and core utilities, but if we use bash as the default shell or use some of the GNU coreutils, we get kernel faults or segfaults (respectively). This happens both on the FPGA and in Spike.

I used the "new" branch of freedom-u-sdk. You can replicate the issue if you configure buildroot to use bash as the default shell.

I am trying to modify makefile for changing ISA ,which is there in freedom-u-sdk

I want to build a sifive port for supporting ISA-rv64ima.Here I am modifying makefile, instead of "ISA ?= rv64imafdc" i am planing to change "ISA ?= rv64ima" and here question is what to give instead of "ABI ?= lp64d". Please give me solution to my problem.

Thanks in advance

trying to fetch instructions from an MMIO page

I use these tools to make my bbl

riscv-gnu-toolchain @ b4dae89
linux @ 87cb3b7
riscv-pk @ e2aad2d
riscv-qemu @ cd2c21d

but when use the command to boot the bbl there is something wrong

./qemu-system-riscv64 -kernel /home/czh/riscv/riscv-tools/riscv-pk/build/bbl -nographic -machine spike_v1.10

qemu show the error information

unassigned address not implemented for riscv
are you trying to fetch instructions from an MMIO page?
unassigned Address: fffffffffffff800

I compile the kerne with defconfig, ues pk tool to make the bbl .
what should I do.

Thanks in advance for your inputs and help

Python build finished, but the necessary bits to build these modules were not found

This happened when I tried make qemu.

gdb can not work on breakpoints.

Hi All,

1. Use qemu to simulate riscv, and it works OK.
   qemu-system-riscv64 -nographic -machine virt -kernel bbl -drive file=rootfs.bin,format=raw,id=hd0 -device virtio-blk-device,drive=hd0 -netdev user,id=net0 -device virtio-net-device,netdev=net0 -S -gdb tcp::12345
2. Use gdb to connect to it
   riscv64-unknown-linux-gnu-gdb
   target remote 127.0.0.1:12345
   symbol-file vmlinux
3. But, when I add breakpoints, it can not beak at it and also print "Register 3921 is not available".
   (gdb) b start_kernel
   Register 3921 is not available

BR,
Peng

Thanks.

PK in the 'new' branch is failing compilation

Trying to rebuild riscv-pk 'new' branch for running the vmlinux image in spike. Since the last few updates of the repository had been giving an error as indicated in the commit note, checked out the last working commit reported in git with the checksum as f08c82a.

This checkout version is also giving a compilation error as below:

$ git status
HEAD detached at f08c82a
$ build_project riscv-pk --prefix=$RISCV --host=riscv64-unknown-linux-gnu
Building project riscv-pk
./libmachine.a(mtrap.o): In function mcall_console_putchar.part.0': mtrap.c:(.text+0x8): undefined reference to platform__use_htif'

./libmachine.a(mtrap.o): In function .L36': mtrap.c:(.text+0x2f0): undefined reference to platform__use_htif'
collect2: error: ld returned 1 exit status

Is this a known issue? Kindly advice resolution.

RISCV-PK Non-CISA build

The architecture field (-march) in the configure script of riscv-pk is hardcoded to build only with rv64imafdc support. The global Makefile has already been modified to take care of both ISA and CISA support but this configure script also should be parametrized to build as per global Makefile -march parameter.

The relevant portion of the code in freedom-u-sdk/riscv-pk/configure script (Line #4084) is as follows:

case "${BUILD_32BIT}" in
yes|default)
echo "Building 32-bit pk"
CFLAGS="$default_CFLAGS -march=rv32imafdc -mabi=ilp32d"
LDFLAGS="-march=rv32imafdc -mabi=ilp32d"
install_subdir="riscv32-unknown-elf"
;;

linux failed to bringup on vc707 board

Hello,

I try to use tag: hifiveu-1.0-2018-03-20 (commit id: 0f03e51) to bring up linux on vc707 board.
My freedom sources are up to date (commit id: 397c395).

However, my terminal hangs as you can see in my terminal log below.
It seems that in both spi-sifive and serial-sifive, they require clock inputs from rocket-chip generated device tree but the clocks are not there. Has anyone encountered this issue before? How can I resolve this issue?

Here is terminal log I got:

Incorrect selection of kernel headers: expected 4.6.x, got 4.1.x

@palmer-dabbelt

The source code has been updated, but it still has the same problem.

According to the guide document, proceed as follows.

1. git clone --recursive https://github.com/sifive/freedom-u-sdk.git

2. cd freedom-u-sdk

3. make

@palmer-dabbelt I'm booting Linux through the simulator, but Buildroot won't except "root" with no password for the login prompt. Any ideas?

failed to boot because of the large image size

Hi guys,
I can boot the Linux use the freedom-u-sdk(commit# af61d6d) on U500 (VC707 FPGA board).
However, when I am adding a simple test program, like helloworld in the ramdisk, it will hang after printing the "SiFive RISC-V Core IP" logo.
I checked that the compiled helloworld occupies 4MB (since I add -static flag during compilation). And the size of bbl.bin becomes from 16M to 20MB.
I have tried to add a simple hello.c file in the ramdisk, and it succeeds.

It seems the bbl has some requirement about the image size?
Any advices to solve this issue?

This is a known problem for buildroot; it stems from having to build m4, which in turn has an old version of gnulib. I believe the buildroot folks patched this in a more recent version -- see here.

It also affects bison, as described here.

The easiest solution problem involves upgrading the buildroot version shipped with the SDK; once I've got the current version working (by applying the patches), I'll try to spend some time seeing how tricky upgrading buildroot would be.

CONFIG_CMDLINE arguments not being passed to spike anymore?

Hi All

A clean 'make -j 32 sim' of freedom-u-sdk at 1dfb584 does not seem to pass CONFIG_CMDLINE arguments into spike anymore?

sbates@hades:~/freedom-u-sdk-2$ make -j 32 sim
/home/users/sbates/freedom-u-sdk-2/work/riscv-isa-sim/prefix/bin/spike --isa=rv64imafdc -p4 /home/users/sbates/freedom-u-sdk-2/work/riscv-pk/bbl
bbl loader


[ 0.000000] Kernel command line:

Changing things on CONFIG_CMDLINE in conf/linux_defconfig seems to cause a recompile of the bbl but no change to that line in the console and no impact on the booting kernel.

Stephen

PS The CONFIG_CMDLINE changes DO appear in the console in a QEMU boot and DO impact that kernel in that emulator.

Linux headers need to be updated in build process?

When I run a "make all" after updating the submodules, the script crashes with an

"Incorrect selection of kernel headers: expected 4.6.x, got 4.13.x
package/pkg-generic.mk:185: recipe for target '../freedom-u-sdk/work/buildroot_initramfs/build/toolchain-external-undefined/.stamp_configured' failed

Any ideas?

Thank you!

No longer possible to check out the version that works with QEMU master

I know this isn't the intended use of this repository but the recent rebasing on sifive/riscv-linux make git submodule update fail for sifive/freedom-u-sdk@5d38ed:

fatal: reference is not a tree: 3989911d0071b93d2e529d22007b7ec783a57532

(5d38ed is the last priv-1.9 freedom-u-sdk; the current rev is priv-1.9.1, which is not supported by qemu.)

Can not SSH to qemu?

Hello All,

I run "make qemu" the linux is boot with U/P=root/sifive.

The IP of qemu is configured by default as below
inet addr:10.0.2.15 Bcast:10.0.2.255 Mask:255.255.255.0

In host, I configure its IP as
inet addr:10.0.2.30 Bcast:10.0.2.255 Mask:255.255.255.0

From the host, I ping the qemu (and vice versa) and all packets are lost. When I do "ssh [email protected]", an error message showed below
ssh: connect to host 10.0.2.15 port 22: No route to host

Do you have any idea to resolve this issue? Many thanks !

Build without support of Compress ISA

We are trying to build the tool chain without the support of compression ISA set.

We did the following changes in the different files for this purpose:
a) In the Makefile @ freedom-u-sdk directory, we changed the rule for building bbl as follows:
$(bbl): $(pk_srcdir) $(vmlinux_stripped)
rm -rf $(pk_wrkdir)
mkdir -p $(pk_wrkdir)
cd $(pk_wrkdir) &amp;&amp; $&lt;/configure
--host=$(target)
--with-payload=$(vmlinux_stripped)
--enable-logo
--with-logo=$(abspath conf/sifive_logo.txt)
CFLAGS="-mabi=lp64d -march=rv64imafd" $(MAKE) -C $(pk_wrkdir)

• Basically, replaced the architecture support of rv64imafdc to rv64imafd in the last line of the rule.

b) In the riscv-pk/configure script, made the change in the CFLAGS and LDFLAGS for a 64-bit architecture as follows:

case "${BUILD_32BIT}" in
yes|default)
echo "Building 32-bit pk"
CFLAGS="$default_CFLAGS -march=rv32imafdc -mabi=ilp32d"
LDFLAGS="-march=rv32imafdc -mabi=ilp32d"
install_subdir="riscv32-unknown-elf"
;;
*)
CFLAGS="$default_CFLAGS -march=rv64imafd -mabi=lp64d"
LDFLAGS="-march=rv64imafd -mabi=lp64d"
install_subdir="riscv64-unknown-elf"
;;
esac

• Basically, replacing the architecture for the * case above as rv64imafd instead of what was set as rv64imafdc for the architecture in the repository.

After making the above changes in the files, did a 'make clean' and then issued a fresh make and then subsequently make sim. Verified that there was no reference of architecture as rv64imafdc and reference of architecture was only rv64imafd - in the entire make build output - thereby proving that the architecture was never getting set as rv64imafdc through out the entire repository build.

When the bbl has got built and appended with the vmlinux as payload as part of this make, and then spike started this bbl loading, there is an error message that is coming in as part of the load process as below:

On the disassembled bbl executable, 80003434 is having:
80003434: 00066703 lwu a4,0(a2) # 1000 <_ftext-0x7ffff000>

---

For having the support of RV64IMAFD and NOT having the support of RV64IMAFDC ISA, should there be anything else that is done for a successful load up in spike till the login prompt?

Thanks in advance for your inputs and help,

Linux doesn't log into ash on Spike

Hello,

I'm trying to boot Linux on Spike with -p4 using make sim
It has booted but doesn't log in to busybox.
Any idea where the problem did come from? I waited a long time but no reaction.

Best regards,
Noureddine
