Hi,
I've just recieved my ATMEM 89C51RD2 chip, which has In system programming (ISP).
I have managed to get it to load the bootloader and send in the program via FLIP. I can also sucessfully read back and veryfy the contents of the flash, so i know it has programmed.

However when I set the boot conditions to boot the user program, it doesn't appear to work. The program is just a simple program thats writes 01010101 to P1.
All i get is all the ouputs running high.

Can anyone shed any light?

Thanks Anand
