Fairly complete Odroid-C2 support wasn't added in linux upstream around 4.9 or 4.10, as I recall.

This is because flash-kernel doesn't have information about what to do with this device. You'll need to add a stanza to your chroot's /etc/flash-kernel/db something like this: Machine: Hardkernel Odroid XU4 Kernel-Flavors: armmp armmp-lpae DTB-Id: exynos5422-odroidxu4.dtb Boot-Script-Path: /boot/boot.scr U-Boot-Script-Name: bootscr.uboot-generic Required-Packages: u-boot-tools This example is obviously for the odroid-XU4; you'll have to adjust the machine, kernel-flavors and DTB entry for your board appropriately. Alternately, you could probably remove flash-kernel entirely, and just ensure the appropriate .dtb file is available in the chroot's /boot/dtbs/$version/, and configure pxelinux.cfg/default-arm appropriately. I think I added some support for network booting arm boards to ltsp-update-kernels/update-kernels, but it's been a while and it could probably use some updates...

That correctly causes the build process to download and install kernel package linux-image-c2 from the deb.odroid.in/c2 repo. But that fails with some dependency errors. There appears to be some issue with the package kernel linux-image-c2, I can't even get it to install on the regular Ubuntu Mate desktop on the C2. Google indicates there some dependency issues with that package. I guess what really needs to happen is that the correct kernel package needs to be downloaded from the Odroid repos, but that's not happening (see next comment below). > > > The build process gets to the point where it attempts to install > > the package linux-image-generic_4.4.0-66.70_armhf.deb.

I am not very familiar yet with how LTSP works, so not sure how to get build-client script to download the correct kernel package. The latest build on the C2 runs kernel version 3.14.x. Whereas, as you can see above, the ltsp-build-client script is downloading and installing kernel version 4.4.x. Problem is, I don't know how to get the ltsp-build-client script to download the correct kernel version which I believe needs to come from the Odroid repos. > > > and then throws the warning: > > > > Warning: root device does not exist. > > As long as you specify a root device on the commandline, this > shouldn't > be a problem. > Would you be kind enough to tell me how to do that?

Re: [Ltsp-discuss] Ubuntu LTSP for ODROID-C2 fails
Hi Had a similar issue building LTSP for RPI3 using Lubuntu, Xubuntu and Ubuntu Mate 16.04 and the flash-kernel. I could go into the technical details but in the end I had to move up to 16.10 before I overcame the problem. Put simply it seems its an issue with the 16.04 versions of flash-kernel. Try building with 16.10 (and yes I know its not LTS) and see. Regards, Russell On 19/03/2017 14:35, Prince Jeremy wrote: I have setup an Ubuntu server with LTSP server packages installed.

Re: [Ltsp-discuss] Ubuntu LTSP for ODROID-C2 fails
Russell, Thanks for that info. At least now I know it wasn't anything with the steps I was following. Unfortunately, Hardkernel hasn't released an Ubuntu 16.10 build for the Odroid-C2. So I guess I'm stuck waiting for them. In the meantime, I will try to get an arm64 build from the official Ubuntu repos and see if that works.
