Sir,

  Do we have sample code to let customer know how to exit safe-mode of Semper flash ?

  Thanks.

Hello Glen,

Just for clarification, are you actually referring to exiting out of 'Safe-Boot" mode?  If yes, then an initialization failure of the embedded microcontroller or corruption of the nonvolatile configuration registers (within the Flash device) can render the flash device unusable.   However, it is possible to recover the Flash device. 

If the microcontroller embedded in the flash device fails to initialize, a hardware reset can recover the device, (unless it is a catastrophic failure).  This hardware reset must be initiated by the Host controller.  Upon detecting a failed microcontroller initialization, the Flash device automatically reverts to its Default Boot mode (1S-1S-1S) and provides a failure signature in its Status Register.

The Host controller must initiate the hardware reset for the Flash device to recover.

Best regards,

Albert
