1. Unrecognized memory chip with ID = 0xAAAA/0xAAAA.
The DCC Loader upon startup always performs flash memory initialization and responds to host with valid memory ID, and with some parameters which describe current memory chip architecture.
In case DCC Loader fails to initialize or detect memory chip it will respond with default ID = 0xAAAA/0xAAAA – this means memory is not detected. May happen if target is currently in some unrecoverable h/w state or if memory controller is not properly initialized or due to hardware failure of the memory chip.
Replace memory chip.
