Input
  • Some Angstrom GUI setup utilities require superuser password, but do not accept it.
Workaround: login as root.
USB OTG
  • Sometimes the USB OTG port fails to transition from Host mode to Peripheral mode.
Workaround:
  • Unplug the USB cable from the CM-T3730 USB OTG port
  • Remove the USB Gadget driver module from the kernel:
root@cm-t3730:~# modprobe -r g_ether
  • Load the USB Gadget driver module again:
root@cm-t3730:~# modprobe g_ether
  • Plug the USB cable back to CM-T3730 USB OTG port
Power management
  • OTG port: in gadget mode prevents SoC entering sys off mode state.
Workaround: Unload the gadget driver module prior entering the off mode.
  • OTG port: USB flash drive does not work properly after resume.
Workaround: Use USB Host ports for USB flash drives.
  • DSP activity prevents SoC entering sys off mode state.
Workaround: Stop any encoding/decoding process prior entering the off mode.
  • Bluetooth device does not work properly after resume.
Workaround: stop the hciattach process and reinitialize the BT device.
Video Playback
  • In Debian filesystem Demo image sometimes while starting to play a video content with GStreamer in an X window (using omapdmaifbsink video sink element), the video is not shown.
Workaround: change (move) the window position.
