[SOLVED] wifi doesn't work

Chip Platform Rockchip
1

hello everyone
I have some problem with wifi module.
I removed network-manager and configured wifi in /etc/network/interfaces manually.

auto wlan0
iface wlan0 inet static
address 192.168.111.1
netmask 255.255.255.0
network 192.168.111.0
broadcast 192.168.111.255
wpa-ssid name
wpa-psk pass

then

sudo ifup wlan0

and it used to work well.

But after board restarted, interface wlan0 just disappeared…
iwconfig shows only sit, eth0, and lo interfaces.

dmesg without wifi config | grep wlan:
