Hi all,
I'm trying to program 18f4550, using MPLAB ICD2. I successfully compiled several timesat beforehand (with the same board design!!!).But this time something strange happened. This is really killing me, because I tried to solve the problem for last 4 hours and nothing changed. An error message keeps appearing when I try to compile with ICD2.
ICDWarn0020: Invalid target device id (expected=0x4F, read=0x0)
Does it mean my PIC is dead?
I'm using same devices, same board design.
Power is supplied to the board. Therefore I assume there is no failure in the connection.
Does this message appear when there is only hardware failures?
Best Regards
