MAIN/DSP Update Procedure-2
Writing will not be shown even more than about 15 seconds passed after starting playback, audio signal does not output at Sampling frequency:44.1kHz. Check the connection and settings and try again.When another try results in failure again, use the other update method.
DURING FW UPGRADE,DO NOT TURN OFF THE UNIT. DO NOT REMOVE ANY CONNECTIONS.These operation will not allow FW Upgrade any more, andthe whole board or IC will need replacing.
