Repairing the bootloader on the TADA68 using a Pi
The TADA68 is one amazing keyboard. Completely reprogrammable and PBT keycaps at just a hundred dollars! It’s not perfect though, because the bootloader is pretty weird. It’s over 4096 bytes big, which means it is not protected like a normal bootloader would be. Sometimes this goes wrong. Either something went wrong when flashing and flashing your .BIN file again fixes it, but in other cases the bootloader completely breaks. I had the former happen a lot of times so I wanted to replace the bootloader with something else.
