Can't run gtk_hello_world example on STM32MP157F

[MFR]

Hi, I was following the STM32MP157F-DK2 tutorial for developing on ARM Cortex A7. 

I have two problems:

1) Starter package - i have using STM32CubeProgrammer to download the image to a new SD Card, but the board failed to load Linux

2) i have tried the example given for hello_world.c . host cross-compilation is successful, but the program cannot run on the board with the following error messages:

root@stm32mp1:/usr/local# su -l weston -c "/usr/local/gtk_hello_world"
chown: cannot read directory '/home/root': Permission denied
/usr/local/gtk_hello_world: /lib/libc.so.6: version `GLIBC_2.34' not found (required by /usr/local/gtk_hello_world)

appreciate any help.

Hello @MFR ,

Please can you clarify the context.
1) You are saying that you are not able to load Linux with the starter package.
2) You are running running "gtk_hello_world" from Linux. So you were able to reach Linux?

On which ecosystem are you working?
On MP157F-DK2, the recommended tutorial is the latest one, made for DV 5.0.0:
 https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-DK2/Let%27s_start/Populate_the_target_and_boot_the_image

If you still have an issue, please can you share the complete boot traces.

Best Regards,
Kevin

Hi Kevin,
let me clarify the situation. I have using STM32MP157F-DK2 board with Ubuntu 20.04 and followed the "Getting Started" steps where I have tested the gtk_hello_world on the preinstalled Linux (kernel 4.19.94) image that comes with the board. I continue to follow the steps to download the new starter package to a different SD card using the STM32CubeProgrammer. This new downloaded image failed to work, where it hang on the ST splash screen. I have followed the steps and using the latest ecosystem you mentioned.
Fyi, I have also tried the Developer Package Linux kernel upgrade (to upgrade from the preinstalled image to the new kernel version 6.1.28), but same thing it failed to work.

My finding are as follows:
1) Starter package downloading to new SD card happens to screwed up the partition on the new SD card. I have compared the partition structure with the working preinstalled image.
2)Developer package new Linux kernel upgrade stuck at starting the kernel.
3) i have noticed the working preinstalled image are using STM32MP157C-DK2 instead of 157F dtb file, but I guess its compatible correct?

See below of the boot message for the new kernel 6.1.28:

latest:

OpenAMP_TTY_echo also failed to work. No vitual port has been created (no /dev/ttyRPMSG0 or SG1).

your advise is highly sought. I'm planning to use the board for my current project.

Thanks.

Hello @MFR ,

Sorry for the long delay to reply. I hope that you were able to solve your issue, otherwise you can find my reply below.

3) i have noticed the working preinstalled image are using STM32MP157C-DK2 instead of 157F dtb file, but I guess its compatible correct?

Yes, it is compatible to use the 157C-DK2 on a 157F-DK2, but not using 157F-DK2 on a board 157C-DK2.

Regarding your issue, you have to follow the getting started from the beginning and flash the whole image.
In your case you are trying to make work the linux  kernel 6.1.28, the one from ecosystem DV5.0:
https://wiki.st.com/stm32mpu/wiki/STM32_MPU_OpenSTLinux_release_note#Main_software_components

With an U-Boot 2018.11-stm32mp-r4 , which is the U-Boot version of the ecosystem DV1.2 a very very old ecosystem:
https://wiki.st.com/stm32mpu-ecosystem-v1/wiki/STM32MP15_OpenSTLinux_release_note_-_v1.2.0#Main_software_components

So the structure of the flash and the interaction between the boot levels are completely different.
Please can you follow the tutorial as adviced previously: 
https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-DK2/Let%27s_start/Populate_the_target_and_boot_the_image

If you flash the starter package of the DV5.0 as explained here, everything should work.
If this still doesn't work, please share your whole boot logs with me.

Best Regards,
Kevin
