#76497 - RE: AT89C51Rx2 ISP - Bootloader address Responding to: ???'s previous message |
For the AT89C51RD2 0xf800 is the entry point for the bootloader. At least it is according to the 'sample' code on Atmel's site. According to the data sheet for the AT89C51RD2 (and 'ED2) 0FC00H is the entry point for the bootloader. I am not familiar with other Atmel derivatives which fit into your description "AT89C51Rx2". Which one are you using? I have used the AT89C51RD2. I also tried the AT89C51ED2 and AT89C51RB2 and both worked as described. Note that the data sheet for the 'RB2 is a mess. It refers to the boot loader address as 0FC00H, but in another section it says it is 0F800H. It also makes references to the old Temic T89... parts. -- Tom Bachmann |
