if you can program it with your universal programmer then the chip should be fine.
not sure if this will help you, In the Atmel version (AT89C51RD2) when I had trouble with the bootloader I would just read a brand new chip with the universal programmer and copy it to the one that was not working including the fuse settings. (I use a labtool 48XP universal programmer). Works every time for restoring ISP functionality. If you erase the chip with your universal programmer, you will erase the bootloader! I have the file here somewhere, not sure if it will be the same for the device you are using. Good Luck |
