Exception handling

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 ;

// load into variable

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.
