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?

After reset is staying that way.
