As no one has any insight into why I'm getting a config register value
of 0x3c when downloading pcode, I am into speculation mode.
To refresh people's memory: All of DL, DLM, and HBDL refuse to download
the pcode to my chip, and HBDL reports that my config register is set
to 0x3c. I have replaced my HC11 with a new one, and still get 0x3c.
Three questions then:
1. As the error occurs when I begin to write to RAM, is it possible that
I have a bad RAM chip, and this returned config register value of 0x3c
is somehow a result of that?
2. Is there any other bit of hardware on the board that could poop out and
result in HBDL returning a config register value of 0x3c?
3. Are there *any* suggestions for diagnostic tests I could perform to
track down this error?
Cheers, Skye.
