You can find the NFS setup instructions in the Android BSP User Guide. Also, Android_Frequently_Asked_Questions.pdf is an useful document.
thanks jimmychan.
according to the docs you provided, have running android on my board, but i can't get root permission for some apps, then my question is : how to get the root permission.
i installed SuperSU, but can't found icon on desktop or app draw, and others app like kingroot, can't get root permission also.
thanks for reply.
I had set the "androidboot.selinux=disabled" and "androidboot.dm_verify=disabled" in uboot.
but i still can't get root permission with App, and no dialog display on screen for permission request.
then what should i check? thanks.
