How to customize kernel for Lemaker's Lebian9 (need System V IPC enabled)

Hello,

I would like to use Xtion PRO LIVE on Lebian9 with pre-built TensorFlow(hereafter called Lebian9-tf).
However, in order to use this, it was necessary to enable “System V IPC” in kernel configuration.
(https://3dclub.orbbec3d.com/t/simpleviewer-cant-work-well-log-shows-xiron-os-failed-to-create-a-mutex/830)
This function is used by OpenNI library, and disabled in Lebian9-tf kernel.

I tried to build kernel. I used the kernel source code is here.->(https://github.com/96boards-hikey/linux)
I executed command list is:

git clone < github link >
cd linux
git checkout hikey970-v4.9
make mrproper
sudo cp /proc/config.gz ~/
gzip -d ~/config.gz
cp ~/config .config
sudo chmod 666 .config
make menuconfig
< enabled kernel config >
make -j4
sudo cp arch/arm64/boot/Image /boot
sudo cp arch/arm64/boot/dts/hisilicon/kirin970-hikey970.dtb /boot
< reboot >

Unfortunately my built kernel source did not work…

The functions I need are as follows.
・ build-in TensorFlow
・ GUI interface
・ possible HDMI output
・ kernel enabled System V IPC <-- I want to enabled…

Could you tell me how to customize kernel on Lebian9-tf?
Or you know how to create equivalent img?

I am looking forward to reply.
Thank you.

These steps look about right to me. What does “did not work” mean (how did it fail to work)?

I guess the big question is whether https://github.com/96boards-hikey/linux exactly matches the source used by Lemaker. I think you’d have to ask the Lemaker folks about that.

Thank you for reply, danielt,

When I introduced my custom kernel, Hikey 970 did not seem to start.
However, since WiFi and PCIE LED is blinking, it seems to be running…?
I looked just like to did not working HDMI output.

I guess the big question is whether https://github.com/96boards-hikey/linux exactly matches the source used by Lemaker. I think you’d have to ask the Lemaker folks about that.

I think so too, it is important to check whether it exactly matches the source used by Lemaker.
(I’m currently contacting Lemaker, but I have not received a reply for a week…)

If you get no HDMI output it might be worth comparing serial logs from the broken and working kernels. Hikey970 has a (read only) debug UART on the second type-C connector.

I used UART for debugging for the first time … Thank you for the advice.

The boot log of the custom kernel is as follows.

Weird. There seems to be a fair bit missing from both logs which makes it hard to figure out what happens in what order. Is there anything on the kernel command line to make things quieter (quiet or loglevel=).

I realized that after you built the kernel nothing has been done to deploy the modules (make modules_install). I can’t tell with the abridged logs but that might be necessary too.
