Hi,

   I am doing a Project using STM32L4 Microcontroller, keeping Reference of Available Example Codes i am able to Develop a code where i can Write and Read back the data from QSPI-Flash-Memory. 

   But my Requirement is as given below,

 

    1) Receive data from USB and write it on  QSPI-Flash-Memory.  

    2) Read data from QSPI-Flash-Memory and Transmit back through USB.

 

To do this i Re-Generated my code by enabling USB_HS_CDC mode using ST-Cubemx. but this time i am unable to Read / Write data on QSPI-Flash-Memory. 

(Note: i am getting this problem as soon as i am Re-Generating my code by enabling USB in ST-Cubemx )

 

please suggest me how to solve this problem.
