8.2.1 Read/Write Error Actions

If you receive a read or write error:

1. Did you click Debug > Reset? This may produce read/write errors.
2. Try the action again. It may be a one-time error.
3. Ensure that the target is powered and at the correct voltage levels for the device. See the device data sheet for required device voltage levels.
4. Ensure that the debugger-to-target connection is correct (PGC and PGD are connected).
5. For write failures, ensure that “Erase all before Program” is checked on the Program Options for the debugger (see Debug).
6. Ensure that the cable(s) are of the correct length.
