P89V51RC2 does not erase
« 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

Please complete the following:

Download and install the latest version of FM
Start FM
Press F1 to enter debug mode ([Debug] appears at the top)
Choose ISP->Erase and erase only block 0
Choose ISP->Display Memory and view only block 0
Press F2 to exit debug mode

Email me the generated file C:\flashmagic.fmd
Delete C:\flashmagic.fmd

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

You can erase the device using Sector erase.
