Dear Sir or Madam:
We are having difficulty programming the QSPI flash and then let Vybrid (MVF50NS151CMK50) boot from it. Our planned flow is as follows.
However, this approach does not work as expected. Below is what we tried and saw.
- Configured the board for Boot Mode 0b10
- Connected USB cable & applied power
- Started ‘Vybrid MfgTool’ application
- MfgTool sees board connected and begins programming, but reports QuadSPI initialization failed
On the other hand, with the board configured for Boot Mode 0b00 this procedure works properly – MfgTool is able to program the QuadSPI on the board. The catch for Boot Mode 0b00 is that we are unable to blow the efuses to set Vybrid to boot from the QSPI flash. So even we can program it, Vybrid still cannot boot from the QSPI flash because Boot Mode is 0b00 and none of the efuses is blown.
Any suggestions or comments are greatly appreciated.

Hi SL,
You could refer to the following discussion, which provides useful information regarding QSPI module and booting on Vybrid processors:
Hope this will be useful for you.
Best regards!
