Trying to get the provided (Zephyr) TI_HDC Sample running on my nRF5340. Having issues where it doesn't want to bind regardless of address I specify or pins I use. I created my own overlay according to the board. I will post my project files below.
I can run the i2c_scan sample and see it:
Running/building using:
west build -b nrf5340dk_nrf5340_cpuappns && west flash
I noticed that I get this when building, it is saying it is switching to a secure build instead of my specified NS? Not sure if this is a related issue.

I've followed/read the nRF Connect SDK Tutorial - Part 3 | NCS v1.5.0 which goes over the BME280 example a little. I have tried modify that example to work with the TI sensor instead but had similar issues where it doesn't bind.
Not really sure how to proceed here, any help is welcome. I've done other things I'm forgetting but this is the gist of my issue.
Edit: Here is my zephyr.dts output:
