Hi Guys,

 

today I've Updated from

"Armbian_5.67_Nanopiduo_Debian_stretch_next_4.14.90"  to

 Armbian_5.69_Nanopiduo_Debian_stretch_next_4.19.13"

 

now I've the follwing problem on my nanopi duo. It has Wifi onboard (XR819), but after an Update to Kernel 4.19.13-sunxi. my wifi device was lost. Before the Update the wifi device was listet as wlan0.

to avoid configuration errors i also reinstalled the system. It does not work with debian or ubuntu. If i roleback to an older kernel everything works great.

It seems to be a "mmc-pwrseq" issue, maybe using wrong gpio in DT for the power enabling ...

I think this is not a problem, but i downgrade my kernel with the same power supply, and wifi works again. After that i upgrade the kernel to 4.19 and 4.20 and wifi didnt work. Only with 4.19. and 4.20 exit a dummy0 interface.

With the part of the log I've highligthed above, for sure it is the reason why you don't have WiFi, the WiFi chip is attached on SDIO !
