Error while building the kernel image

Hi,

I need some help with building the kernel image. I am newbie to linux environment. I downloaded the kernel code and when i tried to build i get the following error:

$ make v=3 all
CHK include/linux/version.h
CHK include/generated/utsrelease.h
CC kernel/bounds.s
kernel/bounds.c:1:0: error: code model kernel does not support PIC mode
/*

/home/I15255/ganesh/linux-imx6-boundary-imx_3.0.35_4.1.0/./Kbuild:35: recipe for target 'kernel/bounds.s' failed
make[1]: *** [kernel/bounds.s] Error 1
Makefile:985: recipe for target 'prepare0' failed
make: *** [prepare0] Error 2

This is the exact steps I followed to build.

1. I built a config file using make menuconfig and just save the config. I dint modify any value there.
2. I just typed make v=3 all to build kernel image. Should I do anything prior to that ??

Also I tried just 'make', 'make vmlinux'.

Also am using cygwin64 for this process.

imx8mp-a0-nitrogen8mp.dtb not found

Hi I have a nitrogen8mp board, rev 2020-10-08. I am using the Yocto HOWTO here: https://boundarydevices.com/yocto-hardknott-release-for-i-mx8-platforms/

The board does not boot, saying it cannot find "imx8mp-a0-nitrogen8mp.dtb" in the U-boot console. This is nowhere in the yocto build files. Instead, there is a imx8mp-nitrogen8mp.dtb . If I rename the DTB the board continues to boot but pauses after the line

iptables table 'mangle' does not exist

Hi.

I'm trying to use the Nitrogen6Q_W board as a captive portal hotspot.
I'm using the "Ubuntu Xenial for i.MX boards (August 2016, kernel 4.1.15)" image that I got off of the BoundaryDevices website, and I've installed hostapd, coovachilli, and freeradius.

However, CoovaChilli is spewing this error when it tries to set up it's iptables rules:

iptables: No chain/target/match by that name. iptables v1.6.0: can't initialize iptables table 'mangle': Table does not exist (do you need insmod?) Perhaps iptables or your kernel needs to be upgraded.

I've also noticed that the 'nat' table is missing too.

Do I need to recompile the kernel to enable these?
Are they supported at all?
If so, do you have any hints which flags I should change during config?

Also, is it better if I use the kernel tree from the boundary-imx_4.1.15_2.0.0_ga branch, or should I stick with 1.0.0?

Thanks,

opengl segmentation fault on imx6q-sabresd board

Using the same file system (core-image-minimal + OpenGL support, + direct framebuffer) and Linux kernel 3.0.35 I can use the Vivante examples without any problem.

Examples are from gpu_sdk_v1.00.gz (available on Freescale site).

With this new kernel version (3.10.17_1.0.0 beta branch) I get a segmentation fault with both OpenGL and OpenCL examples.

Building mxc_mipi_csi2 as a module results in incorrect images from mipi

Something seem to be wrong with the mxc_mipi_csi2 driver.
When build as a module instead of built in to the kernel all YUV images fetched over mipi is erroneous. The luma component goes missing.

Re-building in kernel results in no problems.

To reproduce:
Change CONFIG_MXC_MIPI_CSI2=y to CONFIG_MXC_MIPI_CSI2=m

Boot on new kernel and try video from OV5640 for example.

This might need to be reported upstream.

[SOLVED] Problem with video on TW6869

I have problem with video scalling. Kernel 3.8.2 , driver as module. Loading driver without problems:

but video looks like this:

Is it hardware issue or driver?
If I scale video to 320 x 288:

DMA Allocation Issue with TW6865 Chip

With the new patches of tw686x applied to the kernel 4.1.15.2, following error (or warning) appears when running gstreamer-1.0 with tw6865 chip.

v4l2bufferpool gstv4l2bufferpool.c:748:gst_v4l2_buffer_pool_start:v4l2src0:pool:src Uncertain or not enough buffers, enabling copy threshold

Moreover in dmesg, I can see following error being repeated when streaming starts :
unexpected p-b buffer

I can clearly see the images in eglvivsink window. But image capturing is pretty slow and in certain occasions, the whole system hangs. I also tried increasing cma and coherent_pool sizes, but issue remains same ! Also set the gpumem=67108864 ! what could cause this "not enough buffers" issue ?

Issue while playing audio on kernel 5.4

Hello,

With BuildRoot mainline (nitrogen8mm_defconfig + alsa + tinyalsa, kernel 5.4 boundary devices, boundary_defconfig), I tried to play audio on my nitrogen8m-mini board with aplay (alsa) and tinyplay (tinyalsa) and I am facing an error.

The audio device seems to be listed by the kernel (ALSA device list: #0: wm8960-audio), but with aplay and tinyplay are exiting on error after about 10s (and no audio played).

# aplay /ring_sound.wav
Playing WAVE '/ring_sound.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
aplay: pcm_write:2058: write error: Input/output error

# tinyplay /ring_sound.wav
playing '/ring_sound.wav': 2 ch, 48000 hz, 16 bit
error playing sample

With the same board (but different kernel version) I am able to play sound with Android (with UI, not tested with aplay nor tinyplay).

I think I am missing something on BR,
Could you please help me? (I need to play audio to verify that my driver integration is OK on mainline)

Thanks,

boundary-imx-n7.1.1_1.0.0-ga - No hardware perf events supported by kernel

I am using i.MX6Q (ARM Cortex A9) based Nitrogen6x board running Android 7.1.1. Kernel (boundary-imx-n7.1.1_1.0.0-ga)

The issue I am facing is with hardware performance events support. Below is the kernel configuration.

dtsi changes --
pmu {
compatible = "arm,cortex-a9-pmu";
interrupts = <0 94 IRQ_TYPE_LEVEL_HIGH>;
}
Kernel macro enabled --
CONFIG_HW_PERF_EVENTS=y
CONFIG_DEBUG_KERNEL=n
CONFIG_TRACE=y
CONFIG_TRACING=y
CONFIG_DEBUG_FS=y
CONFIG_TRACING_SUPPORT=y
CONFIG_FTRACE=y

and with these changes "armv7_a9_pmu_init" probe call succeeds and I am getting "hw perfevents: enabled with armv7_cortex_a9 PMU driver, 7 counters available" kernel log message.
But with 'simpleperf list' it's displaying no 'events' for hw-cache and hardware.

simpleperf list
List of hw-cache events:
List of hardware events:

My question is, how to enable support of hardware events and specifically "cpu-cycle" in kernel?

Basically, I need to enabled hw perf events because we are getting a below failure while executing CTS_R13 on our device running Nougat 7.1.1.

armeabi-v7a CtsSimpleperfTestCases

record_cmd#event_modifier | fail | CtsSimpleperfTestCases E 11402 11402 event_selection_set.cpp:64] Event type 'cpu-cycles:u' is not supported by the kernel

stat_cmd#event_modifier | fail | CtsSimpleperfTestCases E 11402 11402 event_selection_set.cpp:64] Event type 'cpu-cycles:u' is not supported by the kernel

Build a new Kernel

Hi,

I'm going to build a new Kernel for Ubuntu. I followd these steps:
I have downloaded the Kernel source file from https://github.com/boundarydevices/linux-imx6.git
Then coppied the nitrogen6x_defconfig to the main root of the source code as .config.
Then I run make.
After a while I get this error:

  CC      lib/percpu_ida.o
make[1]: stat: lib/hash.c: File name too long
make[1]: *** No rule to make target `lib/hash.c', needed by `lib/hash.o'.  Stop.
make: *** [lib] Error 2

Can anyone help me to solve that and build my own image?

Can't sync time using hardware stamps

Hi, I wish to use PTP to sync device using the fec driver with kernel 2.10.17. 10.0.2_ga.
To do it, I'm using ptp version 1.8.
I'm using the following simple command 👍

• For the master : ptp4l -i eth0 -l 7 -m
• For the slave: ptp4l -i eth0 -s -l 7 -m

In the packet capture, we can see precisionOriginTime is always the same with HARDWARE mode when it changes in SOFTWARE mode (See attached).
I have tried to merge commit to this driver using patches from other branch, but I never succeed to fix it.
Can you help me ?
Thanks in advance.

Sabre Lite / imx6q underclocking?

Hi,

I'm doing some tests on a Sabre Lite eval board, I'd like to assess wifi performance related to the CPU clock.
The kernel (v4.1 but I've upgraded to v4.10 too) dts files contain 396 MHz, 792 MHz, etc. but I'd like to go down to 200 MHz, and a simple modification to the dts file (I added 198000 to imx6q.dtsi) didn't yield the expected results (while the scaling and cpuinfo sysfs files contain the new values, cpuinfo_cur_freq stays at 398000 and no measurable performance changes observed).

I was wondering if I could get some pointers.

Regards,

Get code for kernel.

Hi,

I have downloaded Image for Nitrogen Max board for Ubuntu, it works fine.
kernel version for it is as below.
root@nitrogen:~# uname -a
Linux nitrogen 3.10.53-15-boundary-7t5 #15 SMP PREEMPT Tue Jul 21 14:07:28 MST 2015 armv7l armv7l armv7l GNU/Linux
r

From where i can get source code for this kernel version.

Thanks in advance.

Support for gcc9

Could you update the repository to be the same as the https://github.com/Freescale/linux-fslc/tree/4.14-2.0.x-imx which is now kernel 4.14.126 which includes the changes needed for building with gcc9.

Set MMC device index via devicetree alias

Slab leak in Android Kernel

Hi,

When trying Android 8 on a Sabrelite, I encounter an issue (located in the kernel (4.9.88 - commit 2324d06)).

The "Slab memory" is leaking when the graphics system (SurfaceFlinger) does composition.

For example, I wrote an application that pop a Toast as fast as possible.

Before running the test, cat /proc/meminfo gives:
Slab: 42092 kB
SReclaimable: 15076 kB
SUnreclaim: 27016 kB

After Running the application for 10-15 minutes:
Slab: 78960 kB
SReclaimable: 14828 kB
SUnreclaim: 64132 kB

After killing the application:
Slab: 80956 kB
SReclaimable: 14960 kB
SUnreclaim: 65996 kB

The "SUnreclaim" is not freed.

Could you please help me to fix this issue.

Thanks,

TW686x driver crash at VIDIOC_REQBUFS.

platform: imx6q
kernel version: 4.1.15

I have write a v4l2 program to get frame from tw6865, but sometimes the kernel will crash at
ioctl(fd_cap_v4l, VIDIOC_REQBUFS, &rq_buf))

full code is below:

    rq_buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
    rq_buf.memory = V4L2_MEMORY_MMAP;
    rq_buf.count = V4L2_BUFFER_NUM;
    if(ioctl(fd_cap_v4l, VIDIOC_REQBUFS, &rq_buf)) {
        printf("this device dose not support mmap\n");
        goto error;
    }

The dmesg is here:
