Hi, 

       The error was solved after following the Document. Thanks for the solution.

       I tried to update the DAPLINK firmware for the QSPI flash . As per the document's "Updatng the DAPLink frmware" section everything went smoothly and I downloaded the QSPI support firmware from the OpenSDA Serial and Debug Adapter|NXP  and copied to the "MAINTENANCE" folder once the copying was succesful the folder was automatically renamed to RT1050-EVK. But the QSPI flashing was a unsuccessful one.

So I thought of reverting the changes , I copied the Hyperflash Supporting DAPLINK firmware to the MAINTENENCE folder and tried to flash to hyperflash using MCUXpresso, but READ timeout error is occuring.

Now If I connect the EVKB  to my WINDOWS PC  an empty Removable Disk is popping up

How can I revert back my board to the earlier condition?

Hi ,

 After trying with different PC's USB port the EVKB detected as a mass storage device under the name RT1050-EVK.

Thanks & Regards,
