Till our interface board get ready, I like to test my linux GPMC driver. Is there any trick (like Ethernet PHY loopback) to test the GPMC with-out the target device? Thanks.
The GPMC Bus Keeping Support can be used as a simple physical loopback to test the single word write/read, timing diagrams (using Logic Analyser) and basic driver operations.
