I'm in the process of reverse engineering an old music peripheral (circa 2002 or so) that has a SH3-7706 processor in it. My goal is to fix a few niggling bugs.
I'm at a point where I need to be able to re-flash the device in the event I brick it (and being able to debug in situ would be a huge bonus). I did some research and found that I needed an E10A-USB to connect to the U-HDI pads on the PCB. I purchased a dev kit for the SH7216 which came with a E10A-USB and wired up a cable to connect the two.
I kept getting errors about targets not being supported in the Workshop program and went through the longer manual for the starter kit and found this line:
"E10A-USB for Starter Kit is a special emulator for only Renesas Starter Kit+ products." :(
So, it seems I wasted a bit of money thinking this would be universal.
Is there any way to make this compatible with this processor, it seems these can be reflashed to support other processors? If so, how would I go about doing this?
This is just a hobby project, not selling or manufacturing anything so I'm hoping this is still possible (and hopefully not expensive).
Any help would be greatly appreciated! I've poured a lot of time into disassembling and reverse engineering the code and would hate to have all that go to waste. I had assumed once I saw the U-HDI pads on the schematic that this would be something I could do. In retrospect, I probably should have tried this first.
thanks for reading
