STM32CubeIDE build failed because of drivers errors

[OBaselga]

Hi,

A few weeks ago, I created a STM32CubeIDE project for STM32MP157F-DK2 where wrote my CM4 firmware. Everything went well. However, today I decided to make little changes in the code and now there are strange errors when building. IT IS NOT POSSIBLE, I HAVEN'T CHANGED ANYTHING RELATED TO THE NEW ERRORS!

In file included from ../Core/Src/main.c:15:

"make -j8 all" terminated with exit code 2. Build might be incomplete.
 
18:17:51 Build Failed. 20 errors, 0 warnings. (took 7s.808ms)

Solution is easy: remove "core_cm4.h" include, but that provokes firmware doesn't work...

Note that the only difference when opening STM32CubeIDE since last time was that IP address had changed. It is already updated in "Debug configurations".

Any ideas?

EDIT

Fortunately, I had a back-up. Checking the differences between both codes, I hav realized that there are new includes which I didn't add consciously. I've recovered the original file and everything works again.

What happens is incomprehensible for me, idk...

Thanks

Hi,

Glad to see you solved the issue, bunch of compile errors usually come from tiny mistake :)
