Merci pour l'aide

The recalbox was running the scrapper for an hour or two. When I checked the screen I had the following error:

There was no music, but the Recalbox Manager was still working and I was able to connect using SSH. I launched recalbox-support.sh (https://file.ac/5jKasNA5rP0/)

It's the first time I have this error, but it's not the first time the system freeze.

I have a Pi 2 model B and I use hardware (microSD card, Game Controller and WiFi dongle) that is on the compatibility list.

Any idea ?

Merci pour l'aide

@oyyodams Je sais que recalbox et raspbian sont différents. Je voulais vérifier sur le forum s'il n'y aurait pas une astuce pour faire fonctionner le wifi. Je vais commander le Edimax EW-7811Un. Merci

@oyyodams C'est un "Comfast" cf-wu810n acheté sur KUBII. Je sais qu'il n'est pas dans la liste des dongle compatibles, mais il fonctionne sans problème avec raspbian.

I did an additional test. I'm able to perform a Wi-Fi network scan. My SSID is in the list.

$ iw dev wlan0 scan | grep SSID
        SSID: FreeWifi
        SSID: FreeWifi_secure
        SSID: le-wifi-de-morgoth
        SSID: FreeWifi
        SSID: Livebox-DE81
        SSID: FreeWifi_secure
        SSID: zita
        SSID: FreeWifi_secure
        SSID: FreeboxNanou14
        SSID: orange
        SSID: Freebox-0C6228
        SSID: FreeWifi_secure
$ 

So the Wi-Fi dongle seems to work properly. The question is why there is no IP assigned to the wlan0 interface ?

• I'm using a Pi 2 (Model B) with latest Recalbox installed (18.07.13). Ethernet network is working, but not Wi-Fi

• Wi-Fi network settings:

  • SSID visible ? Yes
  • Chanel: 3
  • WPA2-PSK/AES

• recalbox network Interfaces without the Wi-Fi dongle

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP8000> mtu 1500 qdisc pfifo_fast qlen 1000

    inet6 fe80::ba27:ebff:fea0:d977/64 scope link 
       valid_lft forever preferred_lft forever
$ 

• I configure Wi-Fi directly in recalbox.conf.

$ grep wifi recalbox.conf
##Activate wifi (0,1)
wifi.enabled=1
##Set wifi region
wifi.region=FR
wifi.ssid=le-wifi-de-morgoth
wifi.key=enc:U2FsdGVkX1/fU30c3mVxGS0ngl1HclFBOFv9Y1qPFFU=
#secondary wifi (not configurable via the user interface)
;wifi2.ssid=new ssid
;wifi2.key=new key
#third wifi (not configurable via the user interface)
;wifi3.ssid=new ssid
;wifi3.key=new key
$ 

• Here's the output of dmesg after connecting Wi-Fi dongle

• A new network interfaces (wlan0) is added but no IP assigned

• I reconfigured the wifi.key with clear text value before rebooting. Still no Wi-Fi after reboot. No problem with this hardware configuration when running raspbian.

• Let me know if you need the complete dmesg output after rebooting the recalbox with the Wi-Fi dongle pluged-in.

• Any idea ?
