I have been using a Rock Pi 4C Plus (v1.2) with M.2 slot with Armbian for some time. I boot from eMMC, but have a 500GB NVME device Cannot recall the original version of firmware installed, but it was originally a Debian bullseye image and I re-installed when a bookworm image became available. I regularly use "apt update" followed by "apt upgrade" to keep the software up to date. After a recent update the system went into a boot loop. I attempted to recover by creating an SD card with the latest Armbian image. When trying to debug the issue I noticed that the NVME in the M.2 slot is no longer recognized. Reverting to previously available 23.11 image and the NVME device is again available. I'll need to dig further to discover what exactly changed between 23.11 and 24.2, but this is definitely a regression for anyone with the earlier version of the 4C Plus using the M.2 slot. So, fair warning anyone using the M.2 slot on a RockPi 4C Plus should avoid updating!

I have both the BPI-M2 Pro and the BPI-M5 and very much appreciate that Armbian is available for them as it is a huge improvement over stock firmware! Ray

I'm powering with a 5V 3A barrel plug power supply. I'm reasonably sure its not a power issue as it has no problem simultaneously supporting 2 USB 3 thumb drives on the USB 3 ports and an SD card reader via the OTG port. I see your lsusb output has: Bus 001 Device 003: ID 0bda:c820 Realtek Semiconductor Corp. 802.11ac NIC Which is what is missing from mine. So it appears I have a defective board! Thanks for the quick responses. Much more helpful than the bananapi forums!

I think you are misunderstanding my issue. The BPI-M2 PRO has an onboard RTL8821CU WiFi which is supposed to be available on the USB bus. Plugging in devices on the 2 USB 3.0 Ports and the USB OTG port have the desired results. The onboard RTL8821CU WiFi just is not recognized. I'm suspect I have a defective board, but was hoping perhaps I was missing something!

Output of armbianmonitor -u is now at: https://paste.armbian.com/wotuxihezo Which does have the output from lsusb which doesn't indicate any USB WiFi device. 🙁

I have recently acquired a BPI-M2 Pro with what is supposed to be USB WiFi (Realtek RTL8821CU). I am running Armbian 22.08.7 Bullseye. armbian-config does not recognize any WiFi. The output from lsusb -t also does not show the presence of USB WiFi as expected. root@bananapi-m2p:~# lsusb -t /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 5000M |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 5000M /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/2p, 480M |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M Do I have a defective device, or is the WiFi not actually a USB module? Is there something else I need to try to enable WiFi? Thanks, Ray
