RPI4 OMV4 WiFi issue- Direct firmware load brcm* failed -2

[electrosam]

Debian v9.4 (stretch)
OpenMediaVault 4
Hardware- RaspberryPi 4

1. Tried to boot from a clean SD card (new etcher install, etcher reported success)
2. Added a user as sudo
3. ssh with this user, and did dmesg | grep brcm. It shows-

$ dmesg | grep brcm

Please help!

RPi4 is pretty new hardware. It probably requires drivers not available in Stretch.

Another update-
I followed steps in this thread and the driver/firmware seems to work-
https://www.linuxquestions.org/question ... 175627137/

Now the output of dmesg is-
root@raspberrypi:/usr/src# dmesg | grep brcm

However even with this, cannot use WiFi-

iwconfig
eth0 no wireless extensions.

lo no wireless extensions.

nmtui does not show wireless yet.

I also tried connecting external USB3.0 rtl8812au WiFi Dongle, it gets detected and drivers are installed. But iwconfig / nmtui does not show WiFI.

Something seems wrong in OMV 4 for RPI?
Why is this happening?
Please help!

You may need firmware-realtek for the USB wifi.

I don't have a RPi yet but thinking about getting one and I would certainly use Raspbian as it's set up to support the hardware. There is an installer available which includes Raspian Buster -
