OK, so while documenting the Armbian patch process I needed something actual to patch. I added gpio-line-names to the device tree, so now all lines are defined. Once I finish the documentation I'll PR this patch. No more guessing what physical pin is! At some point it might make sense to put in jumper and physical pin #.

So I tried switching my MMIO GPIO to /dev/gpiomem from /dev/mem and it doesn't appear to support the GPZ block https://wiki.odroid.com/odroid-xu4/hardware/expansion_connectors#con_11_-_2x6_pins The address is 0x03860000. Hard Kernel's wiringPi doesn't seem to support this either. Should this be a question I ask Hard Kernel folks? https://wiki.odroid.com/odroid-xu4/software/gpio_register_map

Dear Readers I had quite some troubles migrating my armbian system from an SD-Card (16GB) to my emmc (32GB). I'd like to sum up my journey for future travelers ;-) I was not successful simply copying the image of the sd to the emmc and resizing the partition. It would not boot. Apparently emmc has additional boot partitions which must be set correctly. I "repaired" the emmc with this https://wiki.odroid.com/accessory/emmc/recovery_xu4 and it booted Android all right from emmc. I then rebooted on my SD-Card and used the nand-sata-install command to "Boot from eMMC - system on eMMC". It took some time to copy, but when booting on the emmc, still Android. Reboot on the SD-Card again and I manually deleted the emmc-partitions (using parted, fdisk should work just as well) and created a new ext4 partition. I don't know, if the creation was necessary (it got overwritten anyway, as it should). I then used the nand-sata-install command again and chose "Boot from eMMC - system on eMMC". After it finished I checked by mounting the new partition and it looked ok. And then it booted my system from emmc just fine. I can't tell what the problem was initially, may be nand-sata-install got confused by the 4 partitions the Android system had made on the emmc. Many thanks to all contributors of armbian, especially for the very handy nand-sata-install tool! Regards Ivo

I have an array of HC2's running lizardfs. The other units are running 5.4.72-odroidxu4 kernels, but I dared to upgrade one to 5.8.16-odroidxu4 Only this one unit threw a Since the other units didn't I show anything in their logs, I have to assume it isn't because a process running away or a memory leak. line of fstab to mount the spinning rust drive: UUID=be95e207-1768-4fd9-bda9-ddc126a47d50 /chunks/be95e207-1768-4fd9-bda9-ddc126a47d50 xfs rw,noexec,nodev,noatime,nodiratime,largeio,inode64 0 2 Can't think of any additional info that would be useful. If someone has suggestions, i would be interested.

Just doing maintenance tonight on my boxen, regular `apt upgrade && apt update` on ODROID-XU4 and I noticed Debian upgraded to latest kernel (5.8 or whatever). I go look in boot and notice `uInitrd' is pointing at the new Debian version (instead of Armbian version): drwxr-xr-x 4 root root 4096 Nov 15 19:53 . drwxr-xr-x 22 root root 4096 Nov 15 19:50 .. -rw-r--r-- 1 root root 65 Nov 15 19:28 armbianEnv.txt -rw-r--r-- 1 root root 1536 Jun 4 15:24 armbian_first_run.txt.template -rw-r--r-- 1 root root 38518 Jun 4 15:24 boot.bmp -rw-r--r-- 1 root root 4882 Jun 4 15:24 boot-desktop.png -rw-r--r-- 1 root root 12479 Jun 4 15:24 boot.ini -rw-r--r-- 1 root root 64 Jun 4 15:24 boot.scr -rw-r--r-- 1 root root 151722 Oct 18 15:42 config-4.14.202-odroidxu4 -rw-r--r-- 1 root root 238874 Apr 23 2020 config-5.5.0-0.bpo.2-armmp-lpae -rw-r--r-- 1 root root 246529 Sep 26 13:31 config-5.8.0-0.bpo.2-armmp-lpae lrwxrwxrwx 1 root root 22 Nov 15 19:49 dtb -> dtb-4.14.202-odroidxu4 drwxr-xr-x 2 root root 4096 Nov 15 19:49 dtb-4.14.180-odroidxu4 drwxr-xr-x 2 root root 4096 Nov 15 19:49 dtb-4.14.202-odroidxu4 lrwxrwxrwx 1 root root 22 Jun 4 15:24 dtb.old -> dtb-4.14.180-odroidxu4 -rw-r--r-- 1 root root 7011311 Nov 15 19:50 initrd.img-4.14.202-odroidxu4 -rw-r--r-- 1 root root 21912634 Nov 15 19:51 initrd.img-5.8.0-0.bpo.2-armmp-lpae -rw-r--r-- 1 root root 0 Nov 15 19:50 .next -rw-r--r-- 1 root root 2394556 Oct 18 15:42 System.map-4.14.202-odroidxu4 -rw-r--r-- 1 root root 4131671 Apr 23 2020 System.map-5.5.0-0.bpo.2-armmp-lpae -rw-r--r-- 1 root root 83 Sep 26 13:31 System.map-5.8.0-0.bpo.2-armmp-lpae lrwxrwxrwx 1 root root 26 Nov 15 19:53 uInitrd -> uInitrd-5.8.0-0.bpo.2-armmp-lpae # <--- see here -rw-r--r-- 1 root root 7011375 Nov 15 19:50 uInitrd-4.14.202-odroidxu4 -rw-r--r-- 1 root root 21912698 Nov 15 19:51 uInitrd-5.8.0-0.bpo.2-armmp-lpae -rwxr-xr-x 1 root root 5728872 Oct 18 15:42 vmlinuz-4.14.202-odroidxu4 -rw-r--r-- 1 root root 4817408 Apr 23 2020 vmlinuz-5.5.0-0.bpo.2-armmp-lpae -rw-r--r-- 1 root root 4874752 Sep 26 13:31 vmlinuz-5.8.0-0.bpo.2-armmp-lpae lrwxrwxrwx 1 root root 26 Nov 15 19:50 zImage -> vmlinuz-4.14.202-odroidxu4 Only uInitrd was changed, not any others (as you can see).

Hello I can not seem to get my USB Ethernet dongle with a r8152b chip to work on the latest armbian focal release. I tied both kernels 4.14.y. and 5.4.y with no luck. It works on "clean" ubuntu focal when i first plug it it without drivers and when i add the drivers. I am also posting in the odroid fourms here: https://forum.odroid.com/viewtopic.php?f=172&t=38713&p=306027#p306027 I am following these directions: tar -xf r8152.53.56-2.13.0.tar.bz2 cd r8152-2.13.0 make sudo make install lsmod | grep r8 If this works, and if the module does not load at reboot, add "r8152" in modules.conf: sudo vi /etc/modules-load.d/modules.conf or sudo vi /etc/modules.conf. Not sure which one it is on the Ubuntu running on your XU4. At the lsmod step nothing is showing up.

Hello I am wondering if there is a way to get the screen that comes with the OGST to work on Armbian?

Hi, i have odroid HC2 with up-to-date armbian (kernel 4.something - i am not at home, i do not remember its version) I have issues with samba speed - before last minority update it was 115/110 MB/s (read/write) now it is 100/90 with cifs mount in arch linux and 60/60 in Windows 10. Cables, router - everything is untact and still the same cpu governor is on demand, samba is installed over OMV, htop shows max 10%, ram the same where can be the problem?

Hi! my odroid HC2 is running pretty great on armbian 5.90 for >1,5 years (24/7) now. Running a nextcloud instance, with decent perfomance, even when clocked to 600/1200 Mhz in the summer, because of one (1) crash, that I think might have been heat-related. The thing I'm wondering about: in htop, it shows only ( .LITTLE) cores for eight lines, but the cpu is a (.big.LITTLE) architecture and my other HC2 sbc, which runs armbian 20.02.7, show "(.big.LITTLE)" in htop. Perfomance in sysbench is equal on both boards, so this might mean nothing, but it still seemed strange to me. Anyone knows why htop only shows "( .LITTLE)" cores?

Hi .. I try to upgrade to latest armbian. I run now bionic Only when i do sudo apt-get-dist-upgrade i get no upgrade options. I was thinking i need to chage somewhere in setting something with tls. Only... So i cannot find a wiki or a other good working how to. So please can some help me to get my xu4 update tot latest version.. Or give me a good wiki or a working how to. Thanks!!

My HC1 after changing from 4.14.157 to 5.4.6 using armbian-config is not able to get up ... zero response, no boot Does HC1 work with kernel 5 and boot, can anyone confirm?

First I have to thank all maintainers for their work. I ran this server for 1.5 years before something broke. Since armbian is maintained by volunteers I want to cheer you up and thank you for your hard work. However just today my little server would die after apt-update/upgrade. I use a SATA drive together with a boot SD-card (only containing /boot). I can observe the following behavior: The system leds indicate that booting is sucessful (blue LED does blink regularly, I can detect HDD usage by observing the green LED), yet SSH login that I have been using for years now is impossible. The device is also not responsive when pinging it. From my router's dashboard I can not detect a sucessful network connection, yet the NIC's orange LED would blink regularly. Sadly I do not own an UART adapter, maybe I should have bought one sooner. What I have already done: Mirror the SD card using dd. I am uploading the file and will post the link here for review. // Upload finished: https://mega.nz/file/yYJwEIiA#zw4lBfeJ8wXyxS1EeGDpMGERbQquEoxvNaCh2CFwTbg Notice that the focal images seem to be corrupt. I have added focal sources since I needed more modern packages for installing ntopng. Maybe this had something to do with it. I am very glad if someone has some advice, well any advice. I would hate to setup everything again

Linux 2b8e 4.14.150-odroidxu4 #2 SMP PREEMPT Mon Oct 28 08:07:45 CET 2019 armv7l GNU/Linux DB 10.5 updates and upgraded High everybody AAMOE the starting procedure brings very often a new address for local use. As XU4 should be reachable by some other machines automatcally withour searching seconds an seconds I wonder if DHCP6 could help, when searching takes too much time and they already do have fixed IPv6 adresses and DHCP is disgusting. So, how the IPv6 ist made in Armbian? TIA

My board is Odroid HC1 Using balenaEtcher under Windows 10 I have instaled today Armbian_20.05.7_Odroidxu4_buster_current_5.4.50_minimal.img.xz and also was trying before Armbian_20.05.7_Odroidxu4_buster_legacy_4.14.187.img.xz. On both images I wanted to increase verbosity to 7 to see in serial console boot process. Changes in boot.ini are not used during boot until symlink /boot.ini is created which point to /boot/boot.ini Until this is done you will se uboot error that script /boot.ini is not found. Please add this symlink to images for XU4/HC1. Second issue is that editing armbianEnv.txt is not overwriting values in boot.ini. I have added new line verbosity=7 and it has no effect. Only editing boot.ini is changing boot behaviour.

Hi armbian staff and users, i must/try to connect through uart (HC1 /Dev/ttySAC2) to an external uart device. 1. As uart /dev/ttySAC2 is used by boot/kernel, /sbin/agetty has been renamed to stop its launching / lock rather than rebuild uboot/... 2. So as powers supply of 2 uart are differents, 2 converters UART/USB are installed on 2 sides HC1 <-> UART/USB(CP2102N) <=======> USB/UART(XR21V14xy) <-> device. External PS 5v is connected on USB(vcc:gnd), red light on CP2102N is up. I precise 2 points : HC1 <-> UART/USB(CP2102N) <=======> laptop=OK DEVICE <-> UART/USB(XR21V14xy) <=======> laptop=OK Nothing TX/RX, where is the mistake ? Any clue are welcome Best regards Frederic ps: armbian buster 4.14

Hi! my nextcloud instance on an odroid hc2 running armbian has been running stable and smoothly for several months now. Thanks Igor and the whole armbian team! I have one question though: Task: I convert videos with ffmpeg to reduce file size and optimize them for streaming observed behaviour: the CPU is getting very hot! In the evening up to 100 °C (see below), but at noon I have seen temperatures of up to 115 °C! I read somewhere that 110 °C is the critical temperature for the board and the stock hardkernel image has an emergency shutdown implemented. But my board running armbian seems to be negligent of this. On a side note, the CPU frequency reported in armbianmonitor -m is 1800/1300, in htop all 8 cores show 1300 ( .LITTLE)? expected behaviour: shouldn't the CPU be throttled automatically? excerpts from armbianmonitor -m: Stop monitoring using [ctrl]-[c] Time big.LITTLE load %cpu %sys %usr %nice %io %irq CPU C.St. 17:56:51: 1800/1300MHz 2.20 2% 0% 0% 1% 0% 0% 84.0°C 2/13 17:56:57: 1800/1300MHz 2.99 93% 0% 17% 75% 0% 0% 87.0°C 2/13 17:57:02: 1800/1300MHz 3.79 93% 0% 18% 74% 0% 0% 89.0°C 2/13 17:57:07: 1800/1300MHz 3.89 82% 0% 13% 68% 0% 0% 84.0°C 2/13 17:57:12: 1800/1300MHz 3.74 80% 0% 18% 60% 0% 0% 85.0°C 2/13 ... 17:59:19: 1800/1300MHz 9.83 90% 0% 16% 73% 0% 0% 98.0°C 2/13 17:59:25: 1800/1300MHz 10.38 95% 0% 15% 79% 0% 0% 99.0°C 2/13 Time big.LITTLE load %cpu %sys %usr %nice %io %irq CPU C.St. 17:59:30: 1800/1300MHz 10.27 94% 1% 22% 70% 0% 0% 100.0°C 2/13 17:59:36: 1800/1300MHz 9.85 90% 0% 16% 72% 0% 0% 99.0°C 2/13 17:59:42: 1800/1300MHz 10.10 95% 0% 17% 77% 0% 0% 100.0°C 2/13 17:59:48: 1800/1300MHz 10.33 98% 0% 18% 79% 0% 0% 102.0°C 2/13 17:59:54: 1800/1300MHz 10.38 95% 0% 22% 71% 0% 0% 101.0°C 2/13 18:00:00: 1800/1300MHz 10.79 97% 1% 20% 75% 0% 0% 100.0°C 2/13

Hi all, I am trying to add SSH Keys to an HC1. The commands I am using are: sudo mkdir ~/.ssh sudo chmod 700 ~/.ssh sudo nano ~/.ssh/authorized_keys Then I select all the PUBLIC key from PuTTy Gen and copy/paste it on the file above, close and save the file. sudo chmod 600 ~/.ssh/authorized_keys sudo chown -R $(whoami):$(whoami) ~/.ssh/ sudo reboot I then try to SSH with PuTTy and SSH keys. Immediately I get an error saying "Server refused our key" and then it asks me for my normal password as a user. Any idea what I am doing wrong?

I do not use my HC2 for a while. Now I have issue to boot it up. I have download image ubuntu 18.04.3 from official odroid wiki link and during first boot blue led is blinking in heart beat rate forever, I was trying 18.04.1 and first boot run smooth, leds turn off and only red is on, but after reset I can not see my odroid in my network (I used two different cables to check if any is broken). Earlier when I was using it there was no problems.

https://dl.armbian.com/odroidxu4/archive/Armbian_20.05.2_Odroidxu4_bullseye_current_5.4.41.img.xz Third link on XU4 and HC1,2 MC1 download pages are 404 not found. Building an archive for a workshop I'm doing next week and got the 404. No big deal, just wanted to make a note.

I run armbian on an Odroid HC2. Using hdparm -t /dev/sda I get merely roughly 130MB/s on buffered disk reads. This is way below the expected value for my 2TB Crucial SSD. It is obviously not a major issue as the speed is anyway bottlenecked by the gigabit ethernet. I'm just curious, does anyone get better speeds with a similar setup? I read that poor performance can result from a misaligned partition. Checking the alignment with "align-check" of parted does report that the parition alignment is fine, so I suspect this is not the issue in my case.

Hello, first of all please excuse my bad englisch! I have an Odroid HC1 an running OMV 5 with armbian since 1,5 year. When I`m check dmesg i see some problems: root@odroidxu4:~# dmesg |grep imprecise [ 47.446247] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 47.511679] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 47.521702] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 47.591656] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 47.601670] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 47.666068] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 47.678776] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 47.742933] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 47.752947] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 47.815461] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 47.828150] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 47.891943] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 47.908810] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 47.964464] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 47.980735] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 48.059443] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 48.069462] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 48.144206] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 48.254583] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 48.323227] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 49.717492] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 49.786855] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 49.855635] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 49.924987] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 49.992386] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 50.061914] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 50.131333] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 50.199512] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 50.261724] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 50.384336] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 50.440713] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 50.456970] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 50.517214] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 50.573981] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 50.627603] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 50.685894] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 50.749572] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 50.818570] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 50.881186] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 51.027829] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84045.636325] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84045.692550] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84045.742272] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84045.796314] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84045.848398] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84045.904649] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84045.956062] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84046.007744] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84046.060760] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84046.204068] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84047.806436] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84047.861626] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84047.913278] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84047.970381] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84048.034722] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84048.097051] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84048.155366] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84048.210224] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84048.268885] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [84048.422761] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 But I recognized no problems with OMV. Does anyone know something about that issue? Thank`s very much for your help.

Hello I have Odroid xu4 with fan mounted on heatsink. I found several tutorials online and I have one problem. I have Armbian buster with Linux 5.4.28-odroidxu4 I tried edit temp curve and I did it with nano /etc/rc.local # Target temperature: 30°C, 50°C, 70°C TRIP_POINT_0=30000 TRIP_POINT_1=50000 TRIP_POINT_2=70000 echo $TRIP_POINT_0 > /sys/devices/virtual/thermal/thermal_zone0/trip_point_0_temp echo $TRIP_POINT_0 > /sys/devices/virtual/thermal/thermal_zone1/trip_point_0_temp echo $TRIP_POINT_0 > /sys/devices/virtual/thermal/thermal_zone2/trip_point_0_temp echo $TRIP_POINT_0 > /sys/devices/virtual/thermal/thermal_zone3/trip_point_0_temp echo $TRIP_POINT_1 > /sys/devices/virtual/thermal/thermal_zone0/trip_point_1_temp echo $TRIP_POINT_1 > /sys/devices/virtual/thermal/thermal_zone1/trip_point_1_temp echo $TRIP_POINT_1 > /sys/devices/virtual/thermal/thermal_zone2/trip_point_1_temp echo $TRIP_POINT_1 > /sys/devices/virtual/thermal/thermal_zone3/trip_point_1_temp echo $TRIP_POINT_2 > /sys/devices/virtual/thermal/thermal_zone0/trip_point_2_temp echo $TRIP_POINT_2 > /sys/devices/virtual/thermal/thermal_zone1/trip_point_2_temp echo $TRIP_POINT_2 > /sys/devices/virtual/thermal/thermal_zone2/trip_point_2_temp echo $TRIP_POINT_2 > /sys/devices/virtual/thermal/thermal_zone3/trip_point_2_temp This code above is working fine but when I try to edit fan speeds I can't find it $ echo "0 204 220 240" | sudo tee /sys/devices/platform/pwm-fan/hwmon/hwmon0/fan_speed when I do ls -l /sys/devices/platform/pwm-fan/hwmon/hwmon0/ there is no fan_speed file Please can you tell me where is location of file that has attributes to control pwm state so I can do echo from rc.local Why I want to do that, well I have one idea. When I try edit /sys/devices/platform/pwm-fan/hwmon/hwmon0/pwm1 with nano I try several speed of fan. Minimun of my fan is 40 but it doesn't start on that speed but is iq quiet and on that speed temp of my CPU is 43C. This is why I edited target temp. when fan is in stop state 40 in pwm1 doesn't have enough voltage to start fan. But 50 C will activate fan and it will drop to 40 pwm1 and it will keep spining. If it stops, againt 50C activate the fan and so on... I only need $ echo "0 40 120 240" | sudo tee /sys/devices/platform/pwm-fan/hwmon/hwmon0/fan_speed to correct place Thanks. Reply to: soerenderfor I can't reply so I will edit this post I will cut this part of post when system unlock option for reply I get one per day when I do sudo find /sys -name pwm1 | grep hwmon I get /sys/devices/platform/pwm-fan/hwmon/hwmon0/pwm1 I know for that pwm1, I even manualy edited it with nano but some part is constantly being updating this pwm1 and this just replace what ever I try to put in this file. when I do cat /sys/devices/platform/pwm-fan/hwmon/hwmon0/pwm1 I get 120 when I change this 120 to 40 after some time it gets updated to 120 Critical is to find location of that pwm or fan_speed file that contains 120 180 240 which is doing editing pwm1 file so I can echo into that file and problem is sloved. I tried everything but I just can't find that file. If I can find that file odroid xu4 will be extra quiet on performance mode with 43C

Hi all, I wanted to do some cross arch builds on my newly installed Armbian on an Odroid-HC1 buuut, it seems binfmt_misc support is not enabled in the kernel. Can I enable it somehow without recompiling the kernel? Thank you for this great image, kernel 5.4, omg!
