Subj. No wireless device, hence cannot connect wifi networks.
No wireless device in Armbian/Radxa Debian Buster @ Rock Pi 4C
What should be wireless driver/firmware? Want to check if it’s present in my server
Just installed Rockpi4 Debian from radxa github, still no wireless device

SIOCSIFFLAGS: Operation not permittedNice, after updating system and installing https://wiki.radxa.com/Penta_SATA_HAT and rebooting system again, penta sata hat started working, but one more reboot - and rock pi is bricked 
what a piece of …
What do you mean by ROCK Pi is bricked? What power are you using? 12V DC power from the sata hat or the USB C on the ROCK Pi?
By “bricked” I mean it’s not catching any address by DHCP. Since I don’t have DP monitor, network access is the only way I can configure OS.
I am using 12V DC power through SATA hat shipped with kit.
I also remembered now that before the last reboot I noticed that rockpi-penta service was failed due to following:
Dec 01 19:17:54 rockpi4c python3[7025]: this = _mraa.new_Pwm(pin, owner, chipid)
Dec 01 19:17:54 rockpi4c python3[7025]: ValueError: Error initialising PWM on pin
So I enabled interfaces as per https://wiki.radxa.com/Rockpi4/Debian#Common_Hardware_Interfaces.2C_I2C.2C_PWM.2C_SPI.2C_UART.2C_etc
Any ideas? I could even provide ssh access to fresh debian installation on that board.
Yes, please do a fresh Debian installation and provide a ssh access to me via PM.

Wrote to @jack 6d ago, but got no answer. Thinking of giving up and leaving rock pi connected to lan through Ethernet.
Thanks a lot for not helping!
