Enable nv-oem-config on custom bootstrapped os

We are attempting to follow the directions in the developer guide to enable nv-oem-config on a custom Ubuntu 18.04.5 rootfs which was created via debootstrap. All dependencies are installed and we have followed the developer guide directions to enable the service on the image. This image does not contain any GUI, so we are running config on ttyTCU0.

The configuration starts on the terminal but immediately jumps from the “license” to “Lang” to “Timzone” and continues to do this on a loop. Any ideas would be appreciated.

Change the value of this property from ttyGS0 to ttyTHS0 in below config file to try.

etc/nv-oem-config.conf.t194

Thank you for your reply
We are using a custom carrier which uses ttyTCU0 in place of ttyGS0. Changing the etc/nv-oem-config.conf.t194 to ttyTHS0 results in oem-config never showing.

When we follow the exact same procedure using ttyTCU0 (also using the custom BSP), but use the default sample roots, we do not see these behaviours.

We are able to complete the setup If we reconfigure Debconf to run the readline frontend in place of dialog.

Output from systemctl status nv-oem-config-debconf@ttyTCU0
It looks like Ubiquity is starting multiple times

Hi sysopinit,

Due to issue happened at your custom carrier board, please compare the differences between your system and our dev-kit, narrowing it down to some specific causes then maybe you can have clue on why this is happening.
