How to fix it?

There is a communication protocol between A64 and MC. The MC has not replied what it should. It can signal multiple problems.

1. It can be a bug left in the production code.
2. It can be some random malfunction of the A64 or MC. i.e. some EMI, loose contact.
3. It can be a permanent failure of the A64 or MC. i.e. some inputs burned, or the MCU getting stuck due to being damaged.
