    Hi,

    Is there a possibility to map the internal SRAM to address 0x00000000 ?

    So I would be able to use the interrupt vectors without writing to the flash.

    The only way is to put a vector jump table in flash, pointing to ram.

    sample attached.

    Cheers

    i can not found info about it.

    only Flash B0/B1 can be mapped to 0x00000000.
