HA Yellow - flashing OpenThread only firmware

Hi,

I already have a USB dongle with Zigbee and I want to use the embedded Zigbee/Thread chip only for Thread. I’m using the Silicon Labs Flasher add-on with this parameters:

The firmware was uploaded from: https://github.com/NabuCasa/silabs-firmware/tree/main/OpenThreadRCP with this specific URL fimware: https://github.com/NabuCasa/silabs-firmware/raw/main/OpenThreadRCP/NabuCasa_Yellow_OpenThread_RCP_v2.3.1.0_PA32_ot-rcp_hw_460800.gbl.

I’m getting this errors:

What I’m doing wrong with the flash process? Any Ideas?

Thanks.

Finally, I successfully flashed my HA Yellow using the manual procedure described at Flash Silicon Labs radio firmware manually · NabuCasa/silabs-firmware Wiki · GitHub, using the Update Advanced SSH & Web Terminal add-on with “protection mode” disabled:
image

Before that, I have to install the packages described in the thread :Dependency failure when trying to install · Issue #15 · NabuCasa/silabs-firmware · GitHub, because the error: “ERROR: Could not build wheels for cffi, which is required to install pyproject.toml-based projects”:

apk add python3 python3-dev gcc libffi-dev libc-dev

This is the final output:
