another problem: (Android 5.0)Patch code for i.MX6Q failed. c_patch does't work

We want to run android 5.0 on our I.MX6Q. We download the source code,freescale kernel,U-boot,path. Following the Android User's Guide, we now having a problem when patching. After running source /opt/android_L5.0.0_1.0.0-ga_core_source/code/l5.0.0_1.0.0-ga/and_patch.sh and enters help, it shows this:

Invoke ". and_patch.sh" from your shell to add following functions to your enviroment:

-- c_gotop:  Change directory .....

-- c_patch:  Recover working tree...

Then, running c_patch /opt/android_L5.0.0_1.0.0-ga_core_source/code/l5.0.0_1.0.0-ga imx_l5.0.0_1.0.0-ga does't work. It shows c-patch: commond not found. Why c_patch does't work? Was it really add c_patch function sucessfully when running “  source /opt/android_L5.0.0_1.0.0-ga_core_source/code/l5.0.0_1.0.0-ga/and_patch.sh”. How can we patch sucessfully?

Thank you

Hi Yong

dual-role mode (otg) is implemented in chipidea usb driver,

refer to Linux Manual sect.41.2.6 Changing the Controller Operation Mode,

controller mode is defined at dt file, eg arch/arm/boot/dts/imx6q-sabresd.dts

dr_mode =  “otg” /* Set controller as otg mode */

Best regards

igor
