Hi,
Because 89c51 is no longer available I switched to 89v51. I put it instead of 89c51 onto working board (i made the shanges according to the manual). I programmed 89v51 with the same file that was used with 89c51 (it worked fine). The progrmming was successful but the program doesn't start - uart doesn't work, apparently it works only in isp mode. What can be the problem? Does the structure of 89v51 differ from 89c51?
please help.
