P89V51Rx2/P89LV51Rx2 / P89V51RD2 not run
January 23, 2008, 08:09:27 AM
Hello,

for the a little production of old PCB I have to use P89V51RD2 instead P89C51RD2 (because not more available), now I'm trying to
program this new component but I have a problem.
I can program and verify the micro, so I'm sure that I write correctly the code but wen I try to restart the board this don't start.
Is the P89C51RD2 software 100% compatible with P89V51RD2 software?
Do I have to write a bootloader?
I already read the application note TN06007 but I don't find nothing to help me.
Thanks

D
