Hi lyf sci,

When you use the Demo images running on your board, does it boot up success? Here how do you build the BSP, is any error occur during building?

Have a nice day

Hi Dan,

Thanks for the reply.

There is no error observed during the compilation process. But when the USB OTG cable remains plugged in then the above issues doesn't comes. Here how to disable the Suspend/resume in the Freescale AOSP ?

Hi Lyf,

Sorry for late reply. When the android system boot up, and then go to sleep mode, when you insert other device such as USB flash disk， mouse or keyboard by USB OTG the system will awake. So here you can go to the setting options on your android system, to set the display time. It will be OK.
Have a great day,
Dan
