1Programming the Bootloader
Program the ZDI bootloader using the flash utility included with the dbgutils package that is part of the Z8 Encore Tools repo.
./flashutil -u -c 5330000 -p /dev/ttyUSB0 zdiloader.hex
Where:
- -u enables 8-pin device OCD Interface unlock sequence
- -c sets the clock frequency during programming
- -p specifies the first CP/M 50 Mk II serial port
- zdiloader.hex is the firmware

I don't see any link to the "dbgutils" package, and have not encountered it before. Would be great to get a little more on how this is done. For example, is this programmed on your board, or with some sort of adapter cable?

Good question. The Z8 Encore Tools repo contains dbgutils. I've updated the instructions to include the github link, https://github.com/jessexm/dbgutils
The Z8 device includes a built-in programming interface that uses the uart/serial port. The flashutil application uses RTS of the USB serial port to place the Z8 into programming mode.
