Hi,

I managed to configure a custom xubuntu filesystem thanks to the tutorial with a lot of packages installed through qemu... Once the .img is done it boots and everything seems to work except the wifi.
The network manager keeps telling the "device is not ready". Restarting it doesn't change anything.
With :
  1. sudo ifconfig wlan0 up
Copy the code
I got : "SIOCSIFFLAGS: Operation not permitted". It seems the wifi adapter is powered off because there is no rfkill lock and :
  1. dmesg | tail
Copy the code
returns :

[ 2048.920017] dhd_wl_ioctl: returning as busstate=0
[ 2048.920031] dhd_net_bus_devreset: dhd_bus_devreset: -35
[ 2048.923774] sdioh_disable_func_intr: error for read SDIO_CCCR_IENx : 0xffffff92
[ 2048.923798] wifi_platform_set_power = 0
[ 2048.923811] ======== PULL WL_REG_ON LOW! ========
[ 2048.923826] [WLAN_RFKILL]: rockchip_wifi_power: 0
[ 2048.923847] [WLAN_RFKILL]: wifi shut off power.
[ 2048.923860] wl_android_wifi_off out
[ 2048.949115] dhd_stop: Exit
[ 2048.949136] dhd_open: Exit ret=-1

and with
  1. journalctl -ex
Copy the code

I got :

Aug 27 00:20:04 firefly kernel: ======== PULL WL_REG_ON LOW! ========
Aug 27 00:20:04 firefly kernel: [WLAN_RFKILL]: rockchip_wifi_power: 0

Aug 27 00:20:04 firefly kernel: dhd_stop: Exit
Aug 27 00:20:04 firefly kernel: dhd_open: Exit ret=-1

Last, with serial debugging:

[    2.360214] dhd_conf_set_txglom_params: txglom_bucket_size=0

[    2.361398] dhd_conf_set_txglom_params: tx_in_rx=1, tx_max_offset=0
[    2.361945] dhd_bus_devreset:  WLAN OFF DONE
[    2.362395] wifi_platform_set_power = 0
[    2.362735] ======== PULL WL_REG_ON LOW! ========
[    2.363156] [WLAN_RFKILL]: rockchip_wifi_power: 0
[    2.363576] [WLAN_RFKILL]: wifi shut off power.
[    2.364059] dhd_module_init: Exit err=0


The kernel is 4.4.55 (and everything worked with the vanilla filesystem)


Any idea ?

Wow thanks now I realize I miss the entire  /system folder..
How am I supposed to install the firmware stuff ? I followed the guidelines (http://wiki.t-firefly.com/index. ... Build_Ubuntu_rfs/en) but there was no mention of it..
Need I just to copy it from your default filesystem ?
