Other Parts Discussed in Thread: AWR6843AOP, UNIFLASH
I just flashed the mmWave demo "mmwave_sdk_03_06_00_00-LTS" onto my AWR6843AOP and am trying to connect the visualizer to it. It immediately fails when trying to connect to the serial ports.
Here is my board configuration:
I am running on Ubuntu 20.04 with the download version mmWave Demo Visualizer 3.6.0. I have also tried both Firefox and Chrome with the extensions installed but neither behave differently.
Output from "ll /dev/serial/by-id" shows that the radar connects:

However, dmesg shows a "Failed to attach ACPI GPIO chip" error. I have already tried installing the driver from https://community.silabs.com/s/question/0D58Y00008u8b0SSAQ/cp210x-to-vcp-driver-failed-to-build-for-kernel-513-ubuntu-2004?language=en_US but it does not make a difference:
