Exception is thrown when trying to flash

[danielBreitlauch]

Command used:

$ universal-silabs-flasher --device /dev/ttyUSB0 flash --firmware NabuCasa_SkyConnect_OpenThread_RCP_v2.3.2.0_ot-rcp_hw_460800.gbl

Exception:

The machine is an Ubuntu 20.4 on x86. I installed via pip and it is version 0.14

This sounds like a dependency problem. How did you install the package? Try it in a fresh virtualenv.

[danielBreitlauch]

Now I got further along. I did it this way now:

$ pipenv shell
$ pip install universal-silabs-flasher
$ pipenv run universal-silabs-flasher --device /dev/ttyUSB0 flash --firmware NabuCasa_SkyConnect_OpenThread_RCP_v2.3.2.0_ot-rcp_hw_460800.gbl

And got a new exception:

Ah, that is a bug. Thanks!

[danielBreitlauch]

Installed dependencies: Collecting bellows>=0.34.3

Requirement already satisfied: setuptools in /root/.local/share/virtualenvs/testflash-6R93O_W4/lib/python3.8/site-packages (from pure-pcapy3==1.0.1->bellows>=0.34.3->universal-silabs-flasher) (44.0.0)

If that helps.

[Baegi]

@danielBreitlauch I finally found the problem for this. The bellow release 0.37.0 removed the required CONF_DEVICE_BAUDRATE field. Run in your venv

pip install bellows==0.36.8

to force installation of the working version. Flashing worked flawlessly after that.

Got an error related to the same reason today. This was the stack trace:

Did you mean: 'CONF_DEVICE_PATH'?

Setting bellows to 0.36.8 also worked for me.

[danielBreitlauch]

@Baegi THX. That solved it and everything works.

[darkxst]

@puddly this breaks the SL web tools flashers as well it seems.

[puddly]

This has been fixed by https://github.com/zigpy/bellows/pull/597 so the existing web flashers now work again without needing modifications.

https://github.com/NabuCasa/universal-silabs-flasher/pull/47 is the proper fix for this problem, however, so update to sl-web-tools==0.10.1 once it's released.

[darkxst]

Thanks puddly, will update my web flasher once its released!
