Re: Programing P89C51RC2BA by WinIsp

[Francois]

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.
