Hi!

I see that i've a real common problem, that's it:

Now, i'd read "Windows Serial Line Debugging" and i'd follow its
test sequence. But my problem still remain, on I/C board, i notice
that, untill the complete discharge of the mainboard C3 capacitor,
if i activate the mainboard with the SW1 switch, the I/C board yellow
led lightly blink.
Perhaps the problem is on the mainboard, (i'm at step 6 of
the Handy Board Assembling manual) i'd put the board in
bootstrap mode and i'd download the file (PCODE_HB.S19),
but at the end of the process, i saw an error message
("Error at address 0x0000")and the main board battery led
(11R - red one) begun to blink, i'd also tried to change
the U2 static memory chip but nothing happen, the only
difference with the original project is in mainboard U3
chip (transparent latch) because i installed an 74hct373
chip instead of 74hc373 original chip.......please give me
a solution....i'm really sick (sigh)!
