Udoo QUAD: Upgrading to 4.8.6-1 broke wifi & SIM reader

Postby Gorgo » Mon Nov 14, 2016 10:52 am

I flashed the arch image on the website on my Udoo QUAD.
I succeeded in working with wlan0 with wpa_supplicant and nmcli; my dekart dk-38t worked with pcscd too.
I did a pacman -Suy this morning and I updated all the packages.
After that wlan0 disappeared and dmesg doesn't detect if I plug in/off my dekart sim reader.

Code: Select all
[alarm@alarm ~]$ sudo ifconfig wlan0 up                                                                                                               
wlan0: ERROR while getting interface flags: No such device


Code: Select all
[alarm@alarm ~]$ lsmod

Could you help me to manage this problem? Should I reflash the previous image?

I guess that the problem is the same as in my post: UDOO Quad - USB Problems with Kernel 4.8.x as the WiFi module and your SIM-Reader are also both connected via USB. As a workaround, you can downgrade the kernel to the last 4.7.x version:
Code: Select all
pacman -U /var/cache/pacman/pkg/linux-armv7-4.7.6-1-armv7h.pkg.tar.xz
