ODROID C2 USER MANUAL
Other differences are that the block size (bs) parameter for the
dd command is in lowercase, and the USB adapter’s device name is in
the format /dev/diskX. Before writing the image to SD Card or eMMC
module using the “dd” utility, run the command “diskutil” to determine
the device name, then unmount it:
$ diskutil list
$ diskutil unmountdisk /dev/diskX
$ sudo dd of=/dev/diskX bs=1m \
if=./selfinstall-odroidc-eng-s805_4.4.2_dev_master-195-v1.2.img
Inserting the eMMC Module or SD Card
Now that the desired image has been flashed on to the boot me-
dia, it’s time to insert the boot media into the appropriate port on the
ODROID-C2.
Ensure that the work area is clear of unnecessary items. Wear
the grounded wristband. Touch a metallic surface, like that of your desk-
top. Then, open the ODROID-C2 packaging box. Place the anti-static
bag containing the ODROID-C2 board, on to the non-conductive work
surface. Open the bag and remove the board, holding the edges. Avoid
touching any of the components, peripheral connectors, ports, exposed
circuits or on board solder. Place the board on the work surface, with
the bottom side up. Check the annotated diagrams and follow the in-
structions from Chapter 1 for inserting the eMMC module or SD card.
Powering Up
Before powering the board, attach all peripherals as described in
Chapter 1. Insert the power cable, which will be indicated by the red
LED lighting up, and wait for the image to boot to desktop. It will take
anywhere from 20 seconds to 2 minutes for the desktop to appear,
depending on the operating system and the type of boot media used.
Troubleshooting
Red LED not glowing
If the red LED is not glowing, power is not being supplied to the
board. Check the connections, and verify that the plug is inserted
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.
