Hello all, I am using ATMEL Flip S/W to download the hex code to the flash memory.Using Atmel Flip S/W I am able to select the device (T89C51RD2) chip and the communication baud rate 19200.I can see the connection getting established between the board and the flip software.But when i try to erase the program in the flash memory after the above steps, a timeout error pops out and established communication gets disconnected some how?I dont understand why this happens? Has anyone come across a problem like this? looking for your help.
