LPC2xxx / LPC2136 ISP difficulty
August 30, 2006, 08:28:42 AM
I've been programming some boards with an LPC2136 without any problems but the end of the batch have been failing during programming.

Operation Failed. (programming - failed to send data to the device)

After this it says "finished" and increments the counter/plays the sound as if there was no error.


I've noticed there is a different date code on the chips that don't program - is it possible they are different?

I'm using FLASHMagic 3.24.123 and 11.0592MHz crystal at 57600 baud.

All chips show device revision 196387 and bootloader 1.1

Working boards have markings
S60706.1 05
ZPG0540B

Others have
S60799.1 06
ZPG0618B

Help!
