Since Crossworks is supposed to be bulletproof with wigglers, so I
downloaded a trial copy. It won't connect to the target - I get the
message "Cannot identify target. Check JTAG Connections and that the
target is powered" Same message as when there's nothing connected to the
parallel port.

Is it more likely that my olimex-jtag is DOA or it's the jtag port on
the 2129 board? If the olimex-jtag adapter is fried, can it endanger the
board - I have a 2nd board I can try, but don't want to risk frying it.

Your IAR debug macro file must have the following in order to debug from
RAM:

execUserPreload()
{
    __writeMemory32(0x00000002, 0xE01FC040, "Memory"); // MEMMAP = 2;
}
