properly. Also, make sure that a 5V/2A power supply is being used,
and that it is plugged in.
Blue LED not flashing or glowing
If the blue LED is not flashing or glowing at all, something went
wrong with the image writing or the card is not correctly inserted. Try
to download, extract and write the image again. If that doesn’t solve
the issue, try downloading and flashing a different image.
Blue LED solid glowing
The C1 has stopped or frozen due to a kernel panic or software
bug and should be rebooted.
Mouse/Keyboard not working
Ensure that it’s correctly plugged in, or try a different USB port.
You can change it while the C1 is running.
No desktop image
Be patient, since some SD cards require several minutes to boot
and anywhere from 30 seconds to 2 minutes to show the first image.
Refer to the microSD card compatibility list above. Verify that the HDMI
cable is correctly plugged in, and edit the boot.ini on a PC and select
the correct resolution (see Chapter 1 for details).
Some HDMI cables have compatibility issues, so make sure to
use an official Hardkernel HDMI cable. Some monitors have non-stan-
dard EDID functions. In this case, you need to select the non-EDID
mode in the ODROID configuration utility.
Some cables have a shorter plug, and it may be necessary to
remove the plastic case for a better connection. If there is a USB host
port on the monitor, connect a microUSB cable from the ODROID to
the monitor, which creates a ground path between the TV and the
device. Add a short jumper wire between the outer casing of the mi-
croHDMI and microUSB ports to create a ground path.
On the next page the series of steps that should be followed in
order to troubleshoot issues is outlined in detail. Before requesting an
RMA, research the relevant forums and verify that a solution or work-
around doesn’t already exist for your issue.
If your issue has not been previously encountered by anyone,
create a new issue and post it on the forums at http://forum.odroid.
com, then carefully read any feedback and follow the recommenda-
tions. Provide as many details as possible, indicating not only your
software and hardware environment, but also the exact steps to recre-
ate the issue.
