STM32MPF-DK2 external Linux kernel module adding an issue

[mclapd]

Hi,

I am doing "4.Adding an external out-of-tree Linux kernel module" at the below link.

https://wiki.st.com/stm32mpu/wiki/How_to_cross-compile_with_the_Distribution_Package

I am suffering from a module building problem and got the message below. I don't have much knowledge about Linux so it looks pretty hard to fix the issue by myself. Could you kind help me how to solve this issue? Thanks!

Hi @mclapd​ ,

Sorry to come late in this thread.

Did you figure it out or do you still need help ?

Hi Oliver,

I have not fixed the problem but I have dropped the STM32MP evaluation for my project. The development environment setup was very hard for me. If my company wants to resume or use the STM32MP, I will resume the work and ask you to help with my issue. Thanks.
