Enabled cSEC in the bootloader , during any memory write operation in application if power reset happens , we are facing hard fault.
Hi @vramalingam
I think that more details will be needed. Enabled CSEc does not affect memory writes.
What kind of memory writes do you mean? To program flash, data flash, Emulated EEPROM, RAM? If you check the core registers, what's the root cause of hard fault?
