I've tried starting with edge, but none of them work for me. Maybe I have an old u-boot? Mine's on SPI, made with one of your EFI images from 2023.

I'm hesitant to post this here, because I am not really sure that this is an armbian issue to begin with. But I'm somewhat stumped. During the build process I configured the kernel to enable real time threads. CONFIG_NO_HZ_COMMON=y CONFIG_HZ_1000=y CONFIG_HZ=1000 CONFIG_PREEMPT_RT=y However, as I started to migrate my development I discovered I couldn't create a real time thread. So I pulled down areal time test suite (https://wiki.linuxfoundation.org/realtime/documentation/howto/tools/rt-tests) And confirmed it has the same issue: Unable to change scheduling policy! either run as root or join realtime group I am root, it is a real time kernel. Linux bananapim4zero 6.13.7-edge-sunxi64 #1 SMP PREEMPT_RT Thu Mar 13 12:08:08 UTC 2025 aarch64 GNU/Linux I am not sure what might be driving this. For the past several months I've been doing some dev work on a TI AM625 based board that I built a yocto distribution on and it's fine. I know that is a completely different board, but my kernel setting for real time enablement are the same. I pulled them from that build since. Appreciate any input!

hi, its too late (and glad you got documented thing as recommended in FAQ too), but recently I saw quite interesting presentation about reverse engineering unknown old routers, with plenty of info, but only as fun and relax ... at least info that ghidra decompiles any cpu isa into pseudo-c was new to me and it is very close to what I am (OT) trying around my risc-v-alike thing (search github apws vmex) as "aslix", thing slighlty below C ... )) youtube: MEnAKAbz-Y

I just saw your wifi chip in the picture. Unfortunately, this chip only has drivers for older kernel versions. You’ll need to use a usb wifi device or Ethernet.

When select the option of install the driver of wifi, return a message error: Invalid overlay_prefix sun50i_h616 @Nick A
