Stuck on Writing Flash:

[hwiguna]

I'm sure this is user error, but I do not know how to correct it. I've tried two different hex files and one gets stuck at 75% the other at 92%. I've tried specifying 9600 baud. No difference. stuck at same spots. Please advise. Thank you!

Please try again with proper MAX232-based serial interface/s if any available. Also checkout carefully the VCC level, 5V vs 3V3, I had similar problems and they were really caused by that, see e.g.: Trivial solution to "bricked" STC15s

Kind regards and good luck!

It would be worth testing different protocols (stc12 / stc12a / stc12b) and reopen issue if needed.
