Operation not permitted: '/dev/gpiochip0' #73

I don't think this is a hardware issue. What other addons do you have? Integrations? |
Here is my addons, no integration that could possibly use zigbee devices is installed.
One notably thing is that I tried the multi-protocol addon offered by HA, but is unhappy with the buggy experience and decided to flash back to zigbee-only firmware. That's when this error occured.

The issue is that something has exclusive access to the GPIO chip on the Yellow. It's either some other addon or integration. Have you tried rebooting? That may clear it. |
I have tried rebooting, no luck. Maybe it's something access the GPIO chip, how can i findout which process is using it? |
|
Just to confirm, you're using the Silicon Labs Flasher Add-on? I didn't notice it in your list of addons. |
I also used the offical silabs-flasher addon, no luck there. So I installed the homeassistant/aarch64-addon-silabs-flasher docker using portainer, to enable cmd functions inside the docker container, for a more fine-grained cmd functions. |
|
That is likely the problem. Install it from the normal Home Assistant addon repository. |
Can you post a traceback of what happens when you try installing from the normal addon? Make sure to enable verbose mode:

Hi, same mind buddy! I literally just did that! Here is the log: |

Let's get everything back to the defaults by uninstalling the addon and the container from Portainer. Do you have ZHA or Z2M running? If so, they would prevent firmware flashing from succeeding. Disable them first. Afterwards, install the addon, enable verbose logging, pick |
That did not work for me. I might have to factory reset the device this weekend. I will update the situation in this issue. |
Turns out factory resetting the device is not enough. I have to reinstall the entire OS to solve this problem. |

I'm unable to flash my on-board zigbee module on Homeassistant Yellow board. The error showed "Operation not permitted: '/dev/gpiochip0', Here is the log:

Any clue why this is happening? End of the rope here, if you guys cannot help, might have to return my board for factory repair.
