CCS/LAUNCHXL-CC1352R1: TMP007 with sensors boosterpack - Tirtos

Part Number: LAUNCHXL-CC1352R1
Other Parts Discussed in Thread: OPT3001, STRIKE

Tool/software: Code Composer Studio

Hi,

I have a sensors boosterpack and I want to measure the temperature with the TMP007. I have run one example but it doesn't work:

I also ran this version too and it still doesn't work:

The problem is that the board doesn't find the TMP007:

I'd apreciate some help, I'll paste the code below so you can see what I've changed in my program, I'm using Tirtos:
