Arducopter Nooploop Navigation

Im working on the FC of what will be an octacopter. I have only the FC (Pixhawk 6c) connected to Nooploop, I tried with and without using an Ardunio nano , I also tried to use an ESP32 to fix the Tag’s Rx, to no success.

I only get flat lines for D1… D4.
I have followed the instructions from here: nooploop_instruction but I havent been able to arm.

I’m trying to take off in Loiter but it isnt possible since I get a Need Position Estimate
Since the FC is on its own I have turned off all the preArm checks.

I attach the params, bin and some images:
