Bonsoir a tous,

 

voila que j'utilise cette petite mervielle depuis presque 2 ans sans acros, et du jours au lendemain...

bim plus rien

On commence par la config

Raspberry PI4b

Debian bulleyes

Pizigate 1

.

 

niveau test j'ai ca

RPI Model searching ...
All it's OK
Verifying /boot/cmdline.txt ...
+ /boot/cmdline.txt seems to be OK
Searching /dev/serial0...
sh: 1: lsof: not found
+ Port : /dev/serial0 is not used
Verif GPIOs ...
+ GPIO 0 (RESET) --> OK
+ GPIO 2 (FLASH) --> OK
Config GPIOs ...
+ GPIO 0 (RESET) --> OK
+ GPIO 2 (FLASH) --> OK
Opening : /dev/serial0 ...
+ /dev/serial0 opened --> OK
+ Packet 01 02 10 10 02 10 02 10 10 03 sent --> OK
- No packet received - size sent : 11 - error : 11

la led est bien brillante donc en théorie fonctionnelle , pourtant je n'ai plus aucun contrôle sur mes device.

 

Quelqu'un aurais une idée ?
