I have been using a DSPIC30f4011 for two days but suddenly I am no longer able to program the chip again.
The message I am getting:
Failed to verify at programming address 0x0000 (when I click the Verify button).
Failed to program at programming address 0x0000 (when I click the Write button).
Successful (when I click Read button).
Successful (when I click erase button).
I clicked on the erase button and tried to get rid of the error. But when I clicked read after erasing it, the first byte is still 0000 0000. Everything else is FFFF.
I am pretty sure the wiring and power supply is correct because when I put a new chip into the spot where the old chip was at, PICKIT 2 is able to program/verify it.
The pickit shows All protect for both old chip and new chip so it's not a problem.

AVDD and AVSS must be connected.
