摘要
The present application relates to a flash memory controller and a method of operating thereof. A system bus interface is provided to interface with a system bus and a debug bus interface is provided to interface with a debug bus. A flash access control block is provided to perform storage I/O operations on a flash memory array. A debug control block is provided to monitor debug related information. The flash memory controller is configured to selectively operate in one or storage operating mode or debug operating mode. In the debug operating mode: the storage control block is configured to serve only read data access requests; and the debug control block is configured to store trace messages in an allocated part of the storage resources of the flash memory controller in response to trace events. The trace messages are generated on the basis of the monitored debug related information.
