Independently from the IDE, for projects including the CMSIS library, the content of the
registers in the code can also be printed:
void HardFault_Handler(void)
{
volatile uint32_t csfr= SCB-> CSFR ;
printf ( "SCB-> CSFR 0x%08x \n", SCB-> CSFR) // print
while (1)
{
}
}
The same content can as well be obtained directly from the memory with any memory
browser.
Other faults like UNALIGNED, UNDEFINSTR can be managed in a similar way.
