Hi All,

Hi igor,

Thanks a lot!

Has this driver been tested by anyone?

I downloaded the uboot-imx,and checked out to imx_v2019.04_5.4.3_2.0.0 branch.It can be compiled successfully.

The u-boot-dtb.imx can run successfully with my iMX6Q board.However,the fastboot function also failed.

The USB host port of PC can recognize the usb gadget of iMX6Q,but no response to fastboot command.
