P89V51Rx2/P89LV51Rx2 / 89v51 isp problem
September 26, 2012, 01:00:28 PM
Hi,
Used Flash Magic to program a P89V51RC2 in ISP Mode;
When I execute command READ DEVICE SIGNATURE, it gives the error:
"Operation Failed.(reading signature)" or "UNABLE TO COMMUNICATE.(Tx/Rx)..."
I replaced my 89v51rd2 with 89s52, 89c52 and 89c52 but all the time getting same message and many times it hangs at "Reset device into ISP mode now" even after resetting it by hardware.
looking forward for your help.
thanks
