i.MX6 Ubuntu 16.04 (Xenial)

[Davisg]

We have a custom i.MX6 board that is currently running Ubuntu 14.04. I need to upgrade to Ubuntu 16.04. Are there instructions available for installing Ubuntu 16.04? Including changes for systemd support?

Thanks

You may try the same steps for 16.04.

Still stuck...the current boot hangs after the following:

[ TIME ] Timed out waiting for device dev-ttymxc0.device.
[DEPEND] Dependency failed for Serial Getty on ttymxc0.
[ OK ] Reached target Login Prompts.
[ OK ] Reached target Multi-User System.
[ OK ] Reached target Graphical Interface.

I verified CONFIG_FHANDLE=y in kernel configuration.

I did try these steps for Ubuntu 16.04 but the board did not boot. I am making the assumption that I need to make changes to systemd init. I used http://cdimage.ubuntu.com/ubuntu-base/releases/16.04.3/release/ubuntu-base-16.04-core-armhf.tar.gz.

What you mean "the board did not boot"? is only the filesystem not working ? or the u-boot and kernel also not work?

[Davisg]

Sorry...filesystem is not working; u-boot and kernel are good. I am not sure the serial console is being setup correctly. U-Boot 2016.03 and kernel-4.1.15.
