Hi Mike,
We weren't able to get the official Nvidia Ubuntu distribution (R21.5) working on top of the version of Linux that we provide for the arm-camkes-vm. We created our own debian rootfs ourselves using debootstrap. The link to one we created is here (https://drive.google.com/uc?id=0B9-Sswvx8AZ2Tjg2UUQxWExqdnM). You would need to extract the rootfs onto your partition by:
cd destination_directory cat debian.cpio | fakeroot cpio --extract --make-directories --no-preserve-owner --preserve-modification-time
If you don't feel comfortable running some random unsigned OS binaries you downloaded off of the internet, you could build one yourself. When I originally made ours I used debootstrap with software floating point toolchains (armel). I have tried to recreate my process below. It will be faster to do the following on local disk, then move everything over to the sdcard partition at the end.
Hope this helps.
Kind regards, Kent McLeod

I have seL4 running on a TK1 using linux-tk1-initrd. I'd like to get the linux-tk1-debian version running to load the userspace off of the emmc drive of the TK1. FWIW, I did flash the TK1 to the latest verison, R21.5.
The default DTS has root=/dev/mmcblk0p2 in the bootargs. When booting with this, I get a kernel panic. I also tried changing that to root=/dev/mmcblk0p1 (since that partition was the larger one on the emmc). It also gives a kernel panic, albeit a different message.
With mmcblk0p1, the message I get is:
[ 10.092841] EXT2-fs (mmcblk0p1): error: couldn't mount because of unsupported optional features (240) [ 10.102749] EXT4-fs (mmcblk0p1): couldn't mount as ext3 due to feature incompatibilities [ 10.137427] EXT4-fs (mmcblk0p1): mounted filesystem with ordered data mode.

Is there a guide for how to setup the emmc on the TK1 to boot using linux-tk1-debian?
Will an older version of the TK1 image from Nvidia work or do I need to do a custom debian install (like this https://wiki.debian.org/InstallingDebianOn/NVIDIA/Jetson-TK1)?
