Hi Team,

We are working on USB role switch with ci_hdrc.0 controller and hence while doing the gadget configurations using below command

# echo "ci_hdrc.0" > /sys/kernel/config/usb_gadget/g1/UDC

# cat /sys/kernel/config/usb_gadget/g1/UDC

gadget-cdns3

 

Also unable to create # mkdir /sys/kernel/config/usb_gadget/g1/configs/c.1 we are getting mkdir: '/sys/kernel/config/usb_gadget/g1/configs/c.1': Device or resource busy

 

Could you help us get over this

 

Thanks

Redwan
