Which variant of the ARM micro-controller did you order in the end? Was it the same STM32F105RBT6 specified for in HID2AMI?

Cheers.

Whole ARM circuit is the same as the HID2AMI except how it talks to the Amiga. That happens via the CPLD. So if in doubt copy HID2AMI.

And dont do what i did and solder on a JM2020 chip instead of a CPLD because they happened to be in my CPLD box. Doh!

OK so i can boot the CD32 without an accelerator (because i only have one MCA connector left) and i can see the arm and cpld.

My plan was to essentially port this firmware

https://github.com/mist-devel/mist-firmware

over to STM32F105 somehow.

Effectively the user io will work exactly the same way.

EDIT: Does anyone know how to (could they) master CD32 CD with Term + serial.device on it... just enough to interact with the Amiga Serial port if you boot from CD?

I have a number of CD32 bootable cover discs here that include Workbench and serial.device

I'll image one up and provide a link.

EDIT:

Better than me imaging it up and making a hash of it here is a link to one of the discs in CUE/ISO format.

https://archive.org/download/cu-amiga-super-cd-rom-14

You can view the file contents of the iso from the link there as well.

The CUCD's do have serial device but dont seem to have Term on them. Hmmm.

I'm up and debugging with Cube IDE though... but cant see output on the amiga yet.

Way to echo the serial port to the console?

EDIT:

TYPE SER:

seems to work
