You need a genuine bootloader to be programmed to BLOCK1. Is this the one : P89V51RD2_BL_V05.hex (Thanks to Andrew for his "insiders guide to the NXP website") John D. Maniraj said:
Yeah, this could also be the problem I am not able to read back the BLOCK1 boot code after programming (even with the lock bit open). Hummm. What exactly means "I am not able to read back BLOCK1", does it read all FFs, or does it refuse to read? Can chiperase be switched off? Are there any other options to set? Can you program BLOCK1 alone? JW |
