AFAIK RPi-Monitor works, if the device is reachable I'm using https://uptimerobot.com/ for a couple of hosted sites in different places and my own devices, offers ping/port and cron if the device has internet but is not reachable itself, just to see when something is going down

I took the original sources just for the device tree compilation, instructions from https://linux-sunxi.org/Mainline_Kernel_Howto git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git --depth=1 cd linux/ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- sunxi_defconfig edit arch/arm/boot/dts/sun7i-a20-orangepi.dts compile ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make -j4 dtbs copy arch/arm/boot/dts/sun7i-a20-orangepi.dtb to /boot/dtb/ the patch file has more than just phy-mode = "rgmii-id";, I guess you missed it?

? the orangepi mini didn't have the hdmi lines missing

see the patches https://github.com/armbian/build/pull/2750/commits/59797c3324e5f2db4a7727126a770049d274290c

USB seems fine with 5.10.y as the WiFi comes back and also an external WiFi adapter is getting recognized and sees networks, what did you experience? About HDMI, mine is running headless, but I will probably carry it towards a screen later and check // well, anything HDMI related was missing from the orangepi dts so only uboot output worked, compared/copied from other A20 dts et voila, working hdmi output from 5.10.21-sunxi // USB HID works, different WiFi dingle too, no issues here

Created a new dtb with the change described in https://github.com/armbian/build/commit/95b0b601b72d5b28ee22496a42e657bc89ffb420 but to sun7i-a20-orangepi.dts and it seems to solve it, unfortunately adding this as a patch to git is a bit beyond my skills for now :/ another note: setting eth0 to 100Mbit did not solve it before

I just wanted to chip in to confirm that on Orange Pi (A20) Armbian Bionic and Armbian Buster with mainline based kernel 5.10.y become erratic once fdtfile=sun7i-a20-orangepi.dtb is added. Pinging shows ~ 50% packet loss over any the wired interface, uploading a log fails, the headless system is quite unusable, I assume similar in Desktop... A kernel downgrade to 5.9.14-sunxi fixes things, maybe I'll find the time to slowly change to 5.10.y until it breaks, if this narrows done things. /edit my mistake, dues to metric the ping responses where send through the wired interface and got lost, once disabled the system is usable Will try the fix for Banana Pro gmac dtb for the record: happening since 5.10.4-sunxi apparently Thank you for all the work and support you provide here Igor!
