Q.
What are the possible causes of error numbers 1110, 1111, 1112, and 1120, which occur during startup of PDB77?
A.
The most common error in these cases is a bad connection at the evaluation MCU or/and the target board. Please examine each
contact point around the evaluation MCU in the pod, as well as every junction on the PC4816 board and the connection to the target
board. In particular, the socket for the evaluation MCU is a very fine and fragile piece. Even a small bend in the lead or disposition
of the MCU pins may cause a short circuit at the socket junction points.
When one of these errors occurs in a target-less situation, the most probable cause is the evaluation MCU connection. In this case,
you will need to carefully remove any oxidation deposits from the MCU pin with the proper cleanser.
