HelloAfter running the code for about one to two hours I always get Hard Fault exception. Readout of the registers in this Hard Fault while loop are:HFSR=0x4000 0000CFSR=0x8200BFAR=0x20020000MMFAR=0x20020000AFSR=0 Readout of the SP register shows:SP=...

I am looking for an expert to help me with I2C bus on STM32F407IGT. I2C3 is working as expected and I would like to make working also I2C1 and I2C2 which I have problems with.I am using the same initialization regarding registers and I can see the ri...

Thanks for the fast reply.I do not use CubeIDE for this project, I use Atollic TrueSTUDIO.How did you get to idea that it is a divide-by-zero problem?I mean:HFSR=0x4000 0000 -> I have a FORCED hard faultCFSR=0x0000 8200 -> PRECIS ERR and BFAR VALID w...
