Bonjour,
comme indiqué dans mon lien que tu as cité plus haut, s’inspirer
de : GitHub - NabuCasa/universal-silabs-flasher: Flashes Silicon Labs radios running EmberZNet or CPC multi-pan firmware
et de : silabs-firmware-builder/firmware_builds at main · darkxst/silabs-firmware-builder · GitHub
Donc en résumé :
(Atlas en debian 11, en root, gbl en raw, démon plugin désactivé)
# pip install universal-silabs-flasher
# wget https://github.com/darkxst/silabs-firmware-builder/raw/main/firmware_builds/elelabs-elx0x3/ncp-uart-hw-v7.4.1.0-elelabs-elx0x3-115200.gbl
# universal-silabs-flasher --device /dev/ttyS2 probe
# universal-silabs-flasher --device /dev/ttyS2 flash --firmware ncp-uart-hw-v7.4.1.0-elelabs-elx0x3-115200.gbl
EDIT 29/01/2026 :
Avec Debian 12, universal-silabs-flasher s’installe dans un venv :
root@rpi3:~# mkdir venv
root@rpi3:~# python3 -m venv /root/venv
root@rpi3:~# cd /root/venv/bin
root@rpi3:~# source activate
(venv) root@rpi3:~# pip install universal-silabs-flasher
Avec clé USB Elelabs/Popp :
(venv) root@rpi3:~# wget https://github.com/darkxst/silabs-firmware-builder/raw/main/firmware_builds/elelabs-elx0x3/ncp-uart-hw-v7.4.5.0-elelabs-elx0x3-115200.gbl
(venv) root@rpi3:~# ls -la /dev/serial/by-id
lrwxrwxrwx 1 root root 13 Jan 29 12:54 usb-1a86_USB2.0-Serial-if00-port0 -> ../../ttyUSB0
/!\ ATTENTION : le démon jeezigbee doit être en gestion automatique désactivé et arrêté.
