Can you please find the fault instruction?

Add this handler

void HardFault_Handler(void) { while(1) { } }

Once it is captured there, you should see the address of the fault instruction on the stack.

You can refer to this document:

The example triggers this fault:

uint32_t read = *((uint32_t*)0x0007FFFA); uint32_t read = *((uint32_t*)0x20000021);

Regards,

Daniel
