Hey guys, I have a problem with my STM32F4 mCs, that new producted from a PCB manufcturer. I think its about the IOC file, because I can boot them up, but the application files are not readed from main.cpp. Do you have some suggestions to try out?

Hi @Walid ZRELLI​ 

I ordered my pcbs for two times with same design. The first ones are working quite good, I saw that the chip Rev Y, the one not working is Rev 2. (The Y is marked on the chip, and I can see the chip version when the debugger connects). Rev Y is newer, but cannot find any information online how to they differ. But for now, I would guess that all Rev Y chips work and Rev 2 has the problem.

When I debug the code, it seems like it stucks on CAN init(), so I tried to create a scratch project and it seems like there is no problem with it.

New project from scratch -> CAN works on Rev 2 chip.

New project from old IOC without any FreeRTOS code -> fail. So no can problem, but something related to the IOC and code being generated from it. Tried some hours to find what settings cause it, no luck so far ...
