#118621 - it works not yet !!! Responding to: ???'s previous message |
I have now changed the bootvector to the custom bootloader and then Flashmagic works no longer.
It can detect the baud rate and also display the device signature, but every programming function don't work. Fortunately the custom bootloader was able to download a program. But my intention to have a path to change the custom bootloader with Flashmagic seems not possible. Maybe the Flashmagic was confused by some settings, done in the startup code of the compiler prior entering the emergency exit routine. E.g. SP = 7; may solve it. Peter |
