Hello,

i see that if i activate the bootloader with BOOT0=1 and BOOT1=0 the system stay in the bootloader cycle all the time i mantain the pin configured in this way until restart the cpu.

Is possible to jump directly to the main user program if after a timeout no request is coming from outside to the cpu?

I'm asking because i have usually no access to the pcb when the final product is finished and i need to upload new program via bootloader.

Thank you

If you want to control the behaviour you need to get your own loader on the chip earlier in the process.
