User firmware stuck or not starting after reset. #26

Closed curiousmindsdev closed 3 years ago

curiousmindsdev commented 3 years ago

I have a demo firmware toggling 6 LEDs in sequence. I uploaded it using dfu-util but it does not start. First LED turns on and it stops there. I'm guessing that I forgot to add something in my code. DFU_APP_START is set to 0x08001000 and DFU_APP_SIZE is set to 126976 in config file. Also I set FLASH (rx) : ORIGIN = 0x08001000, LENGTH = 124K in my demo project. I've uploaded my demo project along with bootloader.map and config.h file to Google Drive. Can you check if something is wrong?

Tried to debug with your code. I was surprised that F0 series doesn't support ISR table relocation. I see no way to fix this.

Probably I have found a solution. But it needs to be tested.

Could you test with this branch? In a few words, since if we can't set a VTOR we must handle ISR in the bootloader then do a jump to the application ISR.

IT WORKED!!! Thank you so much!!!

Nice solution. I think we want to have this merged
