{{IssueCategory|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 {{cmd|xterm}} from '''Applications->Accessories''' and change the default profile from the command line:
<pre>
enlightenment_remote -default-profile-set Standard-copy
</pre>
}}

{{IssueCategory|Frame buffer console|
* Sometimes the '''Frame buffer console''' is not visible and not possible to use.
:'''Workaround :''' Use the serial or network ssh console.
}}

{{IssueCategory|Bluetooth initialization timed out|
* Sometimes attaching the ttyO1 serial port to the HCI Bluetooth subsystem can time out with the following message:
<pre>
root@cm-debian:~# hciattach -s 115200 /dev/ttyO1 texas 3000000
Initialization timed out.
</pre>
:'''Workaround :''' Reset the WL1271 Bluetooth module manually, then run the '''hciattach''' command again:
<pre>
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
Found a Texas Instruments' chip!
Firmware file : /lib/firmware/TIInit_7.6.15.bts

}}

{{IssueCategory|Network interface name change|
* Network interface name can change if used with rootfs on NFS by more then a single CM-T335 unit.
:'''Workaround 1:''' Delete the udev persistent network interface rules file - should be repeated after every unit replacement:
<pre>
root@cm-debian:~# rm /etc/udev/rules.d/70-persistent-net.rules
root@cm-debian:~# reboot
</pre>

:'''Workaround 2:''' Disable persistent network interface rules:
<pre>
root@cm-debian:~# echo "# disable net-generator rules in /lib/udev" > /etc/udev/rules.d/75-persistent-net-generator.rules
root@cm-debian:~# reboot
</pre>
}}
