How status of boot0 pin to jump application from bootloader

Hi everybody,

I'm trying to implement IAP to jump from bootloader to my application on stm32h743 target.

I m trying to use example code STM32H743-EVAL from ST without success.

I think, i set correctly both linker file, remmaping of VECT_TAB_OFFSET etc.

My question is, what should be the status of boot0 pin ? In my case, it is connected to ground.

Do you have any idea or suggest ?

Thank you

Samir

Jump to bootloader has been discussed many time before. Best way is to do it is in the start up code. Search the archive.

if (( (*(__IO uint32_t*)0x08060000) & 0x2FFE0000 ) == 0x20000000)

Where is your stack situated? This is a crude test for a stack in RAM 0x20000000..0x2001FFFC

Clearly that won't work for RAM at 0x24000000 or 0x30000000

Adjust the test based of what's actually valid in your situation

My RAM start @0x200000000 and end @0x20020000 !

And my flash start @0x08060000
