In addition to the the Android release, Freescale has also released a Beta for Linux, and it appears that we’re two for two today: it also just works on Sabre Lite and Nitrogen6X.
In addition to sources, the release images contain a pre-built kernel and LTIB-based filesystem in typical Freescale fashion.
As with the Android release, I tested it out by copying the uImage file into /tftpboot and extracted the filesystem into an NFS share.
The filesystem is provided as both an ext2 image and a jffs2 image. The ext2 image is easier to use, and I extracted it like so:
~/$ gunzip rootfs.ext2.gz ~/$ mkdir rootfs ~/$ sudo mount -o loop rootfs.ext2 rootfs ~/$ ls rootfs bin etc lib mnt proc sbin sys unit_tests var dev home lost+found opt root share tmp usr ~/$ sudo mkdir -p /L3.0.35_MX6DQ_ER_1208-Beta/ ~/$ sudo cp -ravf rootfs/* /L3.0.35_MX6DQ_ER_1208-Beta/
Then I added a line to the file /etc/exports:
/L3.0.35_MX6DQ_ER_1208-Beta 192.168.0.0/255.255.255.0(rw,no_root_squash,no_subtree_check)
And booted like so:
U-Boot> set bootargs console=ttymxc1,115200 video=mxcfb0:dev=ldb,1024x600M@60,if=RGB666 U-Boot> set bootargs $bootargs video=mxcdi1fb:off U-Boot> set bootargs $bootargs ip=dhcp root=/dev/nfs U-Boot> set bootargs $bootargs nfsroot=192.168.0.95:/L3.0.35_MX6DQ_ER_1208-Beta/ U-Boot> set bootargs $bootargs rootwait U-Boot> dhcp 12000000 192.168.0.95:uImage-ltib U-Boot> bootm 12000000
The system came right up into the almost pointless Gnome U/I, but also provided a shell on the serial port where it was easy to confirm that:
Networking is up:

The kernel modules aren’t present to allow GPU testing and some work will be required to get touch screens working and audio on Nitrogen6x, but this is a lot of functionality for so little effort.
Thanks Freescale!
As with Android, we’ve added the kernel tree to our Github repository.
- Branch L3.0.35_MX6DQ_ER_1208-Beta contains the Freescale code.
- We’ll be adding our goodies on the boundary-L3.0.35_MX6DQ_ER_1208-Beta branch.
We’ll be running additional tests in the coming days. Stay tuned for announcements about these releases.
