Thank you Robert and Bob.
When I try to access the chip via Philips flash utility I get "Can't read
device, device error etc.
When I try to access the chip via JTAG I can't erase or download the flash
in it by I CAN DEBUG CODE ALREADY IN. I get "prefech abort" after around
100 instruction. (CPU fetches instruction which can't execute).
So if I can't erase the flash either way it's dead althrough CPU is
operating :-(
You might want to ask again in the yahoo group. This question comes up
fairly often. The debug failure could just be a program bug or it
could be a JTAG issue, but more information would be needed to track
that down.
The serial ISP problem sounds exactly like what you would get if you
are not pulling down the ISP pin. In that case you can download into
an unprogrammed chip but not again after the first download.
As far as programming via JTAG the obvious question would be what SW
are you using? I don't use the JTAG for programming but others do, so
if they know what SW and HW you are using they may be able to help
further.
