Other Parts Discussed in Thread: UNIFLASH,
I'm trying to flash the xwr64xxAOP_mmw_demo.bin onto the AWR6843AOPEVM, but Uniflash says it cannot connect to the serial port.
To be in SOP flashing mode, I have all switches set to the "down" position except the one on the back (S3) and the top-third one on the front (S1.3). I pressed the top reset button after plugging into the computer and before clicking "load image" in Uniflash.
Trying with S1.3 also down makes Uniflash hang forever on "Opening to COM port".
I am running Uniflash 8.0.0 on Ubuntu 20.04, with sudo so there should be no permission issues.
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:
