Can set up ZHA integration. In the logs I found this when I try to select serial port:

create_serial_connection
raise PermissionError(
"The serial port is locked by another application"
) from exc
PermissionError: The serial port is locked by another application^[[0m
^[[36m2025-04-24 18:56:43.776 DEBUG (MainThread)

But nothing uses /dev/ttyAMA1. Maybe somebody faced the same problem and know how to fix it?

I tried using Siliconlabs-flasher, but also facing errors here 😢

#

This is the flasher configuration 👇

Did you disable all Thread and Zigbee integrations and add-ons using the radio?

oblique cave
#

Don't have any 😢

#

No ZHA or OpenThread integrations in the list or the OpenThread Border Router or Zigbee2MQTT add-on?

This is all I have. 😅

In that case I would shut the system down via the advanced options of the restart menu.
When it is finished shutting down, only the red LED will be active. At that point it is safe to pull the power and plug it back in.

I did that also, but nothing changed 😢
Also tried to wipe everything out and start from scratch - faced same thing. After long hours in communication with ChatGPT you guys are my last hope 😆

What exactly has ChatGPT told to do?

  1. Silicon Labs Flasher
  2. Tried to flash via command line
  3. Suggested to use fuser command to check what's blocking the port fuser /dev/ttyAMA1 (Spoiler alert - no processes using this port)
  4. bellows -d /dev/ttyAMA1 info returns same portal locked error

Added summarise screen shot what I and my robot friend already tried

Is the Compute Module fully inserted in its sockets?
