I need help getting my bootloader to work more than once.
I program my bootloader into ATMega2561 with JTAG programmer, put main program hex on SD card, then reboot microcontroller.
It self-programs and then boots up the main program. All good.
However, it won't do that again. Subsequent reboots are not booting to the bootloader.
Please help! Thanks!
