Does anybody in the forum has successefully programmed Winbond W78E516 using flash utilities downloaded from this website. I have been trying hard, but no luck so far. I feel that the provided documents are far for complete. My problem is that the ISPWRITER.exe does not communicate with the targeted device. Here are what I have done. 1. Program the LDU30919.BIN file into the device via conventional programmer. 2. Tie pin P2.6, and pin P2.7 LOW, and RESET pin HI. 3. Execute ISPWRITER.EXE The problem is that each time I hit CONNET bar, error comes up "connection failed". Eventhough, I have confirmed several times that my RS232 comm worked properly using Hyper terminal program. Any body has any idea? what I did wrong here. JIMMY
