Enlightenment Window Manager
  • If the Touchscreen profile is selected the Settings Panel doesn't have Profiles setting menu. It is not possible to switch the profile.
Workaround : Launch the xterm from Applications->Accessories and change the default profile from the command line:
enlightenment_remote -default-profile-set Standard-copy
Frame buffer console
  • Sometimes the Frame buffer console is not visible and not possible to use.
Workaround : Use the serial or network ssh console.
Bluetooth initialization timed out
  • Sometimes attaching the ttyO1 serial port to the HCI Bluetooth subsystem can time out with the following message:
root@cm-debian:~# hciattach -s 115200 /dev/ttyO1 texas 3000000
Initialization timed out.
Workaround : Reset the WL1271 Bluetooth module manually, then run the hciattach command again:
root@cm-debian:~# echo 0 > /sys/class/gpio/gpio19/value
root@cm-debian:~# echo 1 > /sys/class/gpio/gpio19/value
root@cm-debian:~# hciattach -s 115200 /dev/ttyO1 texas 3000000
