It seems that Windows7 cannot detect i.MX6Q(and i.MX6DL) SDB when the board is in file transfer mode (MTP) in Android 6.0.1_2.0.0.
But the photo transfer mode (PTP) works fine, so I always copy files into /sdcard/DCIM folder and transfer to other folders in the console.
The Android KK4.4.2 works fine in MTP.
So any ideas to improve the MTP mode in Android 6.0.1?
All the best
