Arduino Mega watchdog and bootloader - Microcontrollers
May 06, 2021 · Jumping to the bootloader works most of the time - the application starts after a few ms. But some times the bootloader sits there for 10 seconds or more. However, it manages to recover and start the application again. So I think this is evidence that the bootloader has at least something to do with the issue.

atmega - I can't get WDT (watchdog timer) working on
Jan 14, 2019 · $begingroup$ You are probably using some bootloader which has a wait time of longer than 2 seconds and which is not handling correctly reset by WDT. Good bootloader should check WDRF bit and jump directly to application without waiting. If bootloader is not doing so (and waits more than watchdog time-out period), the MCU will be reset again by WDT.

Jan 01, 2018 · To jump from the application to the bootloader, I do an asm reset, not a goto, to force a software reset that can be detected by the bootloader as a reason to remain in the bootloader. Check out the RCON register. One further thing, remember to reset all the peripherals and any other state when switching between app and bootloader.

Apr 25, 2012 · The bootloader example places a jump table at 0x10000 so your code would validate it is good, then jump to 0x10000 which would then jump to the starting point of the application. Either method is fine. Regards, David

pic - PIC32 - Jumping from application to bootloader
Apr 25, 2018 · Because I need to maintain some GPIO output states when transitioning from the application to bootloader, I'm jumping back into the bootloader instead of using a software reset to get there (which results in the GPIO tri-stating for ~200ms). Before I make the jump, I disable interrupts and clear interrupt flags.
