Hi!

Please, i need your help... Im working on STM32.

I need to scape from HardFault_Handler, without reset, and make an unconditional jump to a concise position...

My code:

void HardFault_Handler(unsigned int * hardfault_args)

{

if (flag==1)

{

void (*fptr)(void);

fptr= (void (*) (void)) (0x08060210);

fptr();

}

 

while(1);

}

but it doesn`t work...

May be I need to clear some register, or set to privileged mode?

Flag is set before the ''dangerous'' zone, to catch the exception....

Please can you help me?

Thank you very much in advance!

Yours

Ed

Addresses for 16-bit Thumb code are ODD
