Title: P89V51RC2 does not erase
Post by: gesingle on August 10, 2006, 06:55:51 AM

I am using FM 3.12 with a breadboarded P89V51RC2FN. I have been able to program, verify, display memory, and erase pages, but cannot erase the entire block (Erase Block 0). Erase All Flash is checked. FM shows Erase Complete (with no delay), but a subsequent read shows it is not erased.

Any ideas of what the problem may be?

Thanks,
Glen

Download and install the latest version of FM

Press F1 to enter debug mode ([Debug] appears at the top)
Choose ISP->Erase and erase only block 0

Yep, noticed (and debugged) the same problem.
Just posted a message (without reading yours).

You can erase the device using Sector erase.
