I have problem with programming my uC by ISP.
PSEN LOW / P2.7,P2.6 , ALE high /, EA +5 V T
The programmer shows
Sending Timing Parameters... Timing Command Failed.
I trace the data exchage
ISP is sending U
uC is sending back U
ISP is sending :0100000214E9
uc is sending back :0100000214E9
uc is supposed to send cr lf after :0100000214E9 and it's not the case
Do you have an idea why?
Try Flash Magic. WinISP has some bugs in it.
Let us know if you still have a problem.
