Buildroot for T-HEAD XuanTie CPU Series

buildroot's Issues

How to enable framebuffer ?

How do i get a framebuffer and HDMI output on the GX6605s ?
The old buildroot had a defconfig for that, but in the latest release i have no idea how to do that.

No compiler in target system

I see that gcc was removed as a legacy option some time ago. Is there currently a supported way to have gcc on a c-sky system rather than only as a cross compiler?

I can't follow the Readme.md

When I git clone, like the readme.md said, I cd to the buildroot, and run the conmmand: "make CONF=thead_9xxf_enhanced_5.10_glibc_br_defconfig",but my terminal told me that it's wrong to run "make" command like this... I am a student beginner ,why the readme file is wrong..

how can i make uImage

how can i make uImage

Taobao buy link

Hi dear do you have wechat

USB.image is not generated

I'm using exactly below commands to make my own image for GX6605s:

git clone https://github.com/c-sky/buildroot.git
cd buildroot
make CONF=thead_610_compat_next_glibc_br_defconfig

and based on the description on this page there must be an usb.img file to copy to the USB flash disk, but there is not such a file for me inside/buildroot/thead_610_compat_next_glibc_br_defconfig/imagesdirectory.
this is whatever generated there:

-rw-r--r-- 1 mhd mhd 3.5K Jul 24 03:02 readme.txt
drwxr-xr-x 2 mhd mhd 4.0K Jul 24 03:19 hw

-rw-r--r-- 1 mhd mhd  19M Jul 24 05:08 rootfs.tar

As I checked there was not any problem during building process and every thing finished successfully!
Even I thought maybe gx6605s is not supported by the latest version, then I downloaded XuanTie Linux v1.0.8 version and tried with it but same result.
Then do you have any Idea whats the problem?

buildroot configuration is lost!

I'm trying to build a customized OS image using buildroot using exactly below provided commands:

git clone https://github.com/c-sky/buildroot.git
cd buildroot
make CONF=thead_610_compat_next_glibc_br_defconfig
make

before the last make in 4th line, everything is going well, but after running the last command make, I received:

This config is from origin buildroot: 
make -C /home/user/workspace/buildroot/buildroot-ded3f9954f158b5d9cd08ae76749eade72fcca3a  O=/home/user/workspace/buildroot/
make[1]: Entering directory '/home/user/workspace/buildroot/buildroot-ded3f9954f158b5d9cd08ae76749eade72fcca3a'
Makefile:926: *** Please configure Buildroot first (e.g. "make menuconfig").  Stop.
make[1]: Leaving directory '/home/user/workspace/buildroot/buildroot-ded3f9954f158b5d9cd08ae76749eade72fcca3a'
Makefile:64: recipe for target 'all' failed
make: *** [all] Error 2

I'm using Ubuntu 18.04 (Ubuntu is a guest OS on Win10 Host using Virtual Box) and as I said before, in my previous commands it connected and downloaded all required resources successfully.
Also When I'm entering the buildroot/buildroot-ded3f9954f158b5d9cd08ae76749eade72fcca3a directory running
make menuconfig
there is no selected config and everything is in the default state.
Then do you have any idea what the problem is or is this possible for me to replace the appropriately configured config file with mine?

swapon: swapfile: Function not implemented

There does not seem to be any swap support. Is it possible to build this when compiling with buildroot?

Thanks in advance.

关于综合的问题

玄铁内核能够拿来跑综合吗？请问具体如何操作？以及memory的拼接替换有没有具体点的教程？

有没有联网的教程，如果能联网就能做很多事情了

RT，想要让这个系统联网，ck610m，有线网卡是ax88772B,或是其他的推荐网卡，网上的联网教程好像不能用在这个系统上。

buildroot如何挂载一个QCOW2的文件系统

执行如下命令，buildroot能正常启动和登录
LD_LIBRARY_PATH=./host/lib ./host/csky-qemu/bin/qemu-system-riscv64 -M virt -kernel fw_jump.elf -device loader,file=Image,addr=0x80200000 -append "rootwait root=/dev/vda ro" -drive file=rootfs.ext2,format=raw,id=hd0 -device virtio-blk-device,drive=hd0 -nographic -smp 1
在上述命令后，添加如下参数，目的是能在/dev/disk/by-uuid下有相应磁盘进行后续mount，但实际上没有
-drive format=qcow2,file=lava-guest.qcow2,if=virtio,media=disk,id=lavates
相同的参数，在fedora上能挂载成功
qemu-system-riscv64 -machine virt -cpu rv64 -nographic -net nic,model=virtio,macaddr=52:54:00:12:34:59 -net user -m 1024 -monitor none -smp 4 -m 2048 -object rng-random,filename=/dev/urandom,id=rng0 -device virtio-rng-device,rng=rng0 -device virtio-blk-device,drive=hd0 -device virtio-net-device,netdev=usernet -netdev user,id=usernet,hostfwd=tcp::3333-:22 -bios Fedora-Developer-Rawhide-20200108.n.0-fw_payload-uboot-qemu-virt-smode.elf -drive format=raw,id=hd0,file=Fedora-Developer-Rawhide-20200108.n.0-sda.raw -drive format=qcow2,file=lava-guest.qcow2,media=disk,if=virtio,id=lavatest

编译时第三步出现问题

执行命令：make csky_gx6605s_defconfig

报错：

请问是什么问题？应该怎么解决

I'm using the latest release, 1.0.4.

Adding Qt support to buildroot for cross compiling.

Building OS image using buildroot is working fine in the default configuration, but I want to add QT package support for cross-compilation for my c-sky board.
Then using menu-config I added Qt support( Qt 5.12) but during building Image, I have received

In file included from ../3rdparty/double-conversion/include/double-conversion/double-conversion.h:31:0,
                 from tools/qdoublescanprint_p.h:151,
                 from tools/qlocale_tools.cpp:42:
../3rdparty/double-conversion/include/double-conversion/utils.h:114:2: error: #error Target architecture was not detected as supported by Double-Conversion.
 #error Target architecture was not detected as supported by Double-Conversion.

I checked the source file in
/home/user/workspace/buildroot/thead_610_compat_next_glibc_br_defconfig/build/qt5base-5.12.2/src/3rdparty/double-conversion/include
path and as expected supported architectures are:

    defined(_M_X64) || defined(__x86_64__) || \
    defined(__ARMEL__) || defined(__avr32__) || defined(_M_ARM) || defined(_M_ARM64) || \
    defined(__hppa__) || defined(__ia64__) || \
    defined(__mips__) || \
    defined(__powerpc__) || defined(__ppc__) || defined(__ppc64__) || \
    defined(_POWER) || defined(_ARCH_PPC) || defined(_ARCH_PPC64) || \
    defined(__sparc__) || defined(__sparc) || defined(__s390__) || \
    defined(__SH4__) || defined(__alpha__) || \
    defined(_MIPS_ARCH_MIPS32R2) || \
    defined(__AARCH64EL__) || defined(__aarch64__) || defined(__AARCH64EB__) || \
    defined(__riscv) || defined(__EMSCRIPTEN__) || \
    defined(__or1k__)  || \
    defined(__microblaze__)
    defined(__mc68000__) || \
    defined(__pnacl__) || defined(__native_client__)
    defined(_M_IX86) || defined(__i386__) || defined(__i386)
    defined(_WIN32)
    defined(__ghs)

which GX6605S or RISC-V is not among them.
Then do you have any idea how we can patch and add GX6605S to it? or is there any other Qt version supporting this architecture?

ck810 futex error?

在CPU CK810时(软件使用的是buildroot v1.0.3)遇到了futex返回错误的问题，希望能得到您的解答或者建议!
遇到该问题时也尝试将版本更新至buildroot v1.0.9.5，问题依旧。
