Title: 89C51RD2BN Communication problem
Post by: akash on January 10, 2007, 11:41:32 am
Hi,
I am a newbi to MPU. This is the first time i developed with MPU. I am ahving problems in reprogramming the 89C51RD2BN. I accidentially ticked the "Erase all Flash+Security+Clks" and stared the operation.
 Now my MPU is not setting connected to the PC and i am getting the message "Unable to connect at specified baud rate. Try reducing the baud rate. Reset the hardware into ISP mode again"

 Please suggest me what can be done..

Thanking you in advance

Did you wait until this operation finished?
