The problem Regression : the raspberry pi zero internal yellow led, disabled in a previous release of pynab, is back to life on my rabbit following 0.9.0 pynab update. Update was succesfully done through the web interface.

Expected behavior The led shall be shut off after startup.

What exact version of the Raspberry Pi kernel are you running? (see Version information on the System Information page).

SonnyT72 commented 3 years ago

I am running Raspbian GNU/Linux 10 (buster) - Kernel 4.19.118+ armv6l

Kernel 4.19.118+ armv6l

This is not really a Pynab bug, but rather a Raspberry Pi kernel related glitch: the logic to toggle the Pi Zero LED on/off was inverted in kernel 5.x :-( A solution for you is to update your kernel from 4.x to 5.x:

either through the apt update / apt upgrade mechanism; Note: you will then also need to rebuild the TagTagTag drivers (https://github.com/nabaztag2018/pynab#1-configurer-les-pilotes-pour-le-son-les-oreilles-et-le-lecteur-rfid-et-redémarrer)
or by reflashing your SD card with the pynab-v0.9.0 image: https://github.com/nabaztag2018/pynab/releases/download/v0.9.0/pynab-v0.9.0.img.xz

Thank you for your answer! I will try the first solution now and give the result here for others to know. If I don't succeed I will then switch to your second solution.

Thanks again to you and the team working hard to bring our rabbits back to life!

If I find how to remove it, I will :)

mehdichaouch commented 3 years ago

In the meanwhile, can you remove the bug label from this issue?

As I know labels can be managed only by @nabaztag2018

pguyot commented 3 years ago

I beg to differ: this is a bug of pynab. We released 4.x images and allowed @SonnyT72 and others to upgrade our code without upgrading the kernel. We definitely should check kernel version and handle the led accordingly.

We definitely should check kernel version and handle the led accordingly.

Indeed; PR #158 for Issue #156 should not have been merged as is. PR #257 does it better...
