ADB not working when using SHIELD TV (2017 edition) open source and binary driver release

Hello,

ADB works fine with OTA updates and the developer only version of the Software Upgrade 6.3.0 OS image for the NVIDIA SHIELD TV (2017, 16GB version). When I flash the SHIELD TV (2017 edition) open source and binary driver release for Software Upgrade 6.2.0 & 6.3.0, ADB stops working.

USB debugging is enabled under Settings->Developer options->Debugging. When I enable USB debugging, I am not prompted to confirm the RSA fingerprint of my ubuntu PC.

I built the SHIELD TV (2017 edition) open source and binary driver release for Software Upgrade 6.2.0 & 6.3.0 using NVIDIA CodeWorks for Android 1R7 under ubuntu 16.04 LTS.

Do I need to modify a system property prior to building the source for ADB to work correctly?

NVIDIA, please advise. Thank you in advance for your assistance.

NVIDIA, do you monitor this forum?

For anyone experiencing the same issue, I changed the buildtype to eng and rebuilt the code. That resolved it.

Example:
