How to Use USB OTG(flashing port) port as a communication port?

[keshavakumarb]

Hi all,
We have custom i.MX6UL based board. Currently we have 2 USB ports. One port is used for Flashing purpose (thorough MFG tool) and another USB is being used as USB debug port. USB debug port is used continuously for debug purpose. USB port which is used for Flashing is always free when it is not used for Flashing purpose. I want to use it as a USB Communication port. For this I enabled USB CDC ACM class in  Linux and connected that port to PC expecting it to  detect as a serial port. But no luck. What are things I should do inorder to use USB port(which is used for flashing purpose through MFG tool) as a communication port. ??

With Regards,

THi,

here are two USB port on i.mx6ul evk board, one is USB OTG with microUSB connector, the other is USB Host.  For HID device, customer can connect it to USB host; for Mass storage, customer can use a USB OTG to HOST cable to connect microUSB connector, and the other side of the cable is used to connect mass storage, such as moble disk or U disk.

Hope this can do help for you.

Have a nice day
