89v51rd2 doesn't run even if progtamming was successful
« on: July 08, 2008, 10:05:15 am »
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.

alex

You don't seem to have a problem with the programmer for the 89v51  but the implementation to convert from P89c51 to P89v51.

My understanding is this forum is for the programming of the device not the implementation of different cores..
