I tried programming my rainbowduino via my seeeduino last night, by following the instructions (and having a blank sketch pre uploaded to the seedunio). The rainbowduino programmed fine, but now the seeedunio is unprogramable.
The symptoms are.
Arduino ide can’t see it or program it.
everytime it is reset, led on pin 13 flashes very fast in a loop forever, immediately after reset.
I tried reflashing the bootloader using the bitbang method, but can’t get past the part where you check the fuses on the seeeduino before erasing.
Does anyone have any ideas as to how I can recover it? would it be possible to reburn the bootloader using a uartSB? or should I try building the parallel programmer to reload it?
