I'm trying to put the monitor in an EPROM so I don't have to download over USB (using FX2 device). I've done everything that I think is needed, but still get monitor error 22 - no code memory at 1212h. The hex file does not contain any data at address 1212! The load completes (i.e. download hits 100%) but debugger won't start up. I do see that during the download, one time, the processor does a read from address 1212h which is probably not an instruction fetch but a read from code memory (since it reads one byte from that region and that's all, while executing up around CXXX). Has anyone successfully gotten the monitor to run on their board?
Yes, we can download code from the debugger and run it. The 9F00 area used by the monitor code is totally functional. We download large programs... and have been doing so for months. the hardware is good.
A phone call would be most effective in figuring this out. Is that possible? We could review everything that I've done, step by step, and perhaps find something. I could arrange to be here at odd hours if that helps. (949) 851-6989 x105
