Hi again,
Some new information on my problem: I have since tried using DL.EXE
with a different serial port and made better progress. Though IC
still will not come up after I power-cycle the board, the download
completes successfully as far as DL.EXE is concerned. There are
no "Expected xx, received yy" problems anymore.
A new and interesting clue: During the bootstrap download phase,
the green SER LED on the I/C board and the green PWR LED on the HB
both flicker visibly. Throughout the download of PCODE_HB.S19 that
immediately follows, however, the green PWR LED on the HB is lit
solid, and the yellow CHARGE LED on the I/C board lights extra
bright (it was on solid at brightness comparable to the red PWR
LED next to it before)! The green SER LED on the I/C board continues
to flicker until the transfer is complete, then goes on solid.
Perhaps a malfunction is occurring between the download phases?
