Can not install drivers on RT kernel

[MatthewReed303]

Hi I get the following errors trying to install the drivers on a preempt_rt kernel:

I need the rt kernel for the codesys plc that will also be running. The RT kernel came from https://github.com/kdoren/linux/wiki

I think it's todo with your drivers trying todo something with kernel headers?

Here is the RPI OS version I'm using https://downloads.raspberrypi.com/raspios_lite_arm64/images/ and it's the raspios_lite_arm64-2023-10-10 version which matches for RT Kernel here https://github.com/kdoren/linux/releases

I also installed the RT kernel headers DEB file and now get something slightly different when trying to install chipsee drivers

I'm wondering if it's possible for you to make driver installer a DEB package in the future? Or provide regular update when each major version of RPI OS is released?

Maybe the Chipsee Image builds can be done with github actions to automate it and provide 2x releases one standard and one with RT for Industrial applications?

[Liu-Xiaoqiang]

The version of your RT Kernel is 6.1.54-rt15 which is not in the tested branches list, try to use the following command,

We will use 6.1.21 branch which is similar to 6.1.54-rt15, but as it is not from Raspberry Pi Official Kernel, we need do some patch.

1. git clone --depth=1 --branch 6.1.21 https://github.com/Chipsee/industrial-pi.git

2. modify Makefile
diff --git a/Makefile b/Makefile

I hope it works.

[MatthewReed303]

@Liu-Xiaoqiang please see my edit update where I installed the RT kernel headers? Still did not work with those. Will try with

sudo apt update
sudo apt install raspberrypi-kernel-headers

When I edit the make file, it's only this line - @dpkg -i $(TOPDIR)/tools/*.deb adding the - ?

[Liu-Xiaoqiang]

It means remove the following line,

@dpkg -i $(TOPDIR)/tools/*.deb

Hi Mention,

From the log, this kernel should need a special compiler.

warning: the compiler differs from the one used to build the kernel The kernel was built by: aarch64-linux-gnu-gcc (GCC) 8.4.0 You are using: gcc (Debian 12.2.0-14) 12.2.0 CC [M] /temp/industrial-pi/gt9xx/gt9xx_update.o gcc: warning: switch ‘-msign-return-address=all’ is no longer supported Maybe you need to check the following guide to compile and use the special gcc 8.4.0Kernel Build Prerequisites · kdoren/linux Wiki · GitHubAfter installing this kernel, the overlay directory is switched to /boot/firmware/6.1.54-rt15-v8+/o/ not the default one /boot/firmware/overlay/I think you should modify the Makefile for every driver to apply this change,For example the Makefile in the gt9xx directory, you should add the following line,

You also need to add this same line in other drivers's Makefile.

As this special kernel use special config, like follow, you also need to add this to all config-.txt file in industrial-pi/preconfig/boot/firmware/config-.txt

[all] kernel=vmlinuz-6.1.54-rt15-v8+ initramfs initrd.img-6.1.54-rt15-v8+ os_prefix=6.1.54-rt15-v8+/ overlay_prefix=o/ arm_64bit=1 [all]

At last, please use the 6.6.20 branch on Chipsee GitHub, I checked the config file which is the same as the special kernel.

Hi @Liu-Xiaoqiang I have tried with the 6.6.20 and using the latest RT build of 6.6.35

admin@codesys:/temp/industrial-pi $ sudo make install

It looks like the 6.6.20 version is looking for exact kernel version of drivers and can't be found?

I think you should modify the Makefile for every driver to apply this change,For example the Makefile in the gt9xx directory, you should add the following line,

What do I need to modify exactly in the Drivers Make files, what is the line?

[Liu-Xiaoqiang]

From the following error, the linux header is missing. Try to install it.

Hi @Liu-Xiaoqiang, What line do I need to add to make files because of overlay is /o and not /overlay? Or does this not matter now I'm using the 6.6.20 version?

[MatthewReed303]

Hi @Liu-Xiaoqiang I decided to just try with the standard RPI kernel 6.6.31 and install the 6.6.20 drivers and the install works fine and no errors, but it's stuck in a boot loop and can't even ssh into it now when I restarted. It's now just a blank screen. I re flashed the RPI OS back on it again and tried again to install the drivers, but same result. Looks like an issue with the drivers?

EDIT:

After leaving it 5min I can now SSH back in but still blank screen, going to now install the desktop and see if that works

EDIT:

Still blank display after installing the desktop I use Here is the /boot/firmware/config.txt
