Download the following file to get U-Boot and Android firmware images for the ConnectCore 6 EA kit (based on the Adapter board):
https://ftp1.digi.com/support/developmentsoftware/82003474_1P.zip
Uncompress the zip the file to your TFTP exposed folder on your development PC.
- boot.img (Android kernel)
- system.img (Android root file system)
- u-boot-ccimx6adpt.imx (U-Boot image)
Connect an Ethernet cable to RJ45 on adapter board. Start a TFTP server.
Start the target and stop in U-Boot. On the boot message check the U-Boot version. If it is different than DUB-2.1.1.2 (lower or higher) you need to replace the boot loader using the downloaded U-Boot image. To update U-Boot via TFTP, you need to firstconfigure the network settings:
=> setenv ipaddr 192.168.42.30
(replace the above IP address with the static IP you can assign to the module)
=> setenv serverip 192.168.42.1
(replace the above IP address with the IP of your development machine running tftp server)
=> update uboot tftp
Do you really want to program the boot loader? <y/N> y

You need to reset the U-Boot environment to the defaults for the recently updated DUB-2.1.1.2 U-Boot. This will however reset the environment variables that hold the MAC addresses. Before resetting, please make sure you write down the MAC addresses of your device. There are three MAC addresses (Ethernet, WiFi, Bluetooth) that should be printed on a label on the ConnectCore 6 module. If not, the MACs can also be retrieved with the following command:
=> printenv ethaddr wlanaddr btaddr
ethaddr=11:11:11:11:11:11
wlanaddr=22:22:22:22:22:22
btaddr=33:33:33:33:33:33
Write them down to be able to restore them later. Then reset the environment with:
=> env default -a
Now restore the MAC addresses with the values read before(will be different on your case):
=> setenv -f ethaddr 11:11:11:11:11:11
=> setenv -f wlanaddr 22:22:22:22:22:22
=> setenv -f btaddr 33:33:33:33:33:33
Note: The variables that hold the MAC addresses have a write-once protection flag , to override the flag use -f along with protected variable.
Configure again the network addresses (lost after thereset):
=> setenv ipaddr 192.168.42.30
(replacethe above IP address with the static IP you can assign to the module)
=>setenv serverip 192.168.42.1
(replace the above IP address with the IP of your Linuxdevelopment machine running tftp server)
Optionallydisable the automatic bootscript by clearing the ‘bootscript’ variable:
=> setenv bootscript
Finally save all the changes in the environment.
=> saveenv
Partition the eMMC for holding Android images by running
=> setenv mmcdev 0
=> run partition_mmc_android
