Hello

I'm doing ICSP on 16F874's using a PICSTART+
If I program the devices with code protect on and then try to reprogram them
I get the "configuration bits not set"
error message from MPLAB.

I asked the local Microchip Tech Support about this and he said that I
should be able to perform a bulk erase by
just clicking the "Erase Flash Device" button on the PICSTART window.

If I do this, then the "active" LED on the PICSTART flashes for a fraction
of a second, but nothing else seems to happen.

I'm using v5.70 of MPLAB and v3.00 of PICSTART firmware.

Do I need a production type programmer to do a bulk erase, or is the problem
down to the in-circuit nature of the programming?


Thanks


Alan
