have a question I can't seem to figure out the answer to. We have existing boards running off the AT89c51RE2 processor. Works great because it supports In-System-Programming. This means we can use BatchISP to program them very easily while they're already socketed on the board.
The issue is, we are now trying to switch to the AT89LP51RD2 and it would seem it supports the same ISP programming, but I can't seem to find anything as far as devices to add to Flip or BatchISP in any way. If I try to just change the device parameter it obviously says that it's not a recognized device because it doesn't know what it is. If I just run the existing batch programmer it connects, opens ports, erases, reads buffer, but then when it tries to program the HEX file to the chip it fails.
Any information in this area would be a huge help. I thank you for any advice!
