Hi friends,

I have a problem

Microcontroller for courses, P89V51RD2 did try the card.

This card is manufactured with the new 'P89V51RD2' processors do not assign a hex file. But former manufactured 'P89V51RD2' processors can throw hex file.

How can I fix this problem. I wonder if my problem, your card or Flash Magic program settings?

I would appreciate if you could help.

This means the device is not sending a 'U' back when it is reset. Put a scope on the RxD and TxD lines of the microcontroller. Do you see the 'U' going in after reset? Do you see anything coming out?
