@SteeMan I added a post in TV boxes running Armbian with complete instructions based on your template: Let me know if there's anything I need to add/correct.

TV Box Name: OSMC Vero 4k CPU: Amlogic S905X Armbian build file name: Armbian_community_25.5.0-trunk.301_Aml-s9xx-box_bookworm_current_6.12.20_minimal.img Armbian_community_25.5.0-trunk.301_Aml-s9xx-box_bookworm_current_6.12.20_xfce_desktop.img DTB file used: meson-gxl-s905x-vero4k.dtb U-Boot used: u-boot-s905x-s912 Kernel Version: 6.12.20 Distribution Installed: bookworm Working Ethernet: Yes Max Ethernet Speed that works: 100Mbps Does wifi work: No Does bluetooth work: Yes Does HDMI audio work: No Additional Comments (provide any additional information you feel is important): WARNING: RISK OF BRICKING! Only proceed if you know what you're doing and are willing to accept the risk of bricking your device! If your use case doesn't require Armbian or the latest Linux kernel, you may want to try these solutions first: Run `systemctl disable mediacenter` from the OSMC terminal and continue from there Simple X11 desktop: https://discourse.osmc.tv/t/testing-x11-simple-desktop-chromium-web-browser-in-a-simple-installer-for-stretch/16846 Headless arm64 Docker: https://discourse.osmc.tv/t/non-official-headless-arm64-docker-solution-for-vero4k/108666/4 Toothpick method doesn't boot Armbian, because standard u-boot config expects kernel.img and dtb.img to be present in a different file format than Armbian provides. Getting Armbian to boot requires changing the u-boot environment to the one provided by aml_autoscript. This can be done from a working OSMC installation or recovery. The method below ensures you can still boot the original OSMC installation by removing the SD card. Prerequisites: Terminal skills and patience Vero 4k with working OSMC installation (https://osmc.tv/wiki/vero-4k/reinstalling-osmc/) USB keyboard and HDMI monitor attached to Vero High quality micro SD card PC with SD card reader Toothpick or similar (non-conducting) SD card preparation: Download latest image: https://www.armbian.com/amlogic-s9xx-tv-box/ Write image to SD card as described in this post: https://forum.armbian.com/topic/33676-installation-instructions-for-tv-boxes-with-amlogic-cpus/ Let's get dangerous! To change the u-boot configuration on the Vero 4k: Boot Vero into recovery by applying power and holding the (left) shift button. This might take a few tries The device should prompt a tty screen. Login with user osmc and password osmc Run the following commands (these are from the aml_autoscript file in the Armbian /boot partition): IMPORTANT: Make sure these lines are exactly correct, because if not it can mess up the boot process and brick your device! fw_setenv bootcmd 'run start_autoscript; run osmcfromsd; run osmcfromusb; run storeboot' fw_setenv start_autoscript 'if mmcinfo; then run start_mmc_autoscript; fi; if usb start; then run start_usb_autoscript; fi; run start_emmc_autoscript' fw_setenv start_emmc_autoscript 'if fatload mmc 1 1020000 emmc_autoscript; then autoscr 1020000; fi;' fw_setenv start_mmc_autoscript 'if fatload mmc 0 1020000 s905_autoscript; then autoscr 1020000; fi;' fw_setenv start_usb_autoscript 'for usbdev in 0 1 2 3; do if fatload usb ${usbdev} 1020000 s905_autoscript; then autoscr 1020000; fi; done' To verify, run `fw_printenv | grep bootcmd` etc. The fun part: boot into Armbian Power off the device: execute `poweroff` command, wait until device light is red and remove power. Insert the Armbian SD card into the Vero 4k. It should go in upside down and all the way until you hear a slight click sound. Apply power again After some u-boot and kernel logs the device should show the Armbian boot up screen Enjoy Armbian on your Vero 4k! Removing the SD card should boot into OSMC from eMMC again. Many thanks to @SteeMan for helping me with the original troubleshooting here: https://forum.armbian.com/topic/49733-installing-armbian-on-vero-4k-does-not-boot-from-sd-card Hardware video acceleration, HDMI audio and WiFi don't seem to work out of the box, but I can imagine that with some effort it's possible.

It worked! The Vero just booted into Armbian, thanks so much! 🎉 🙏

Just a thought, but since the current bootcmd is bootcmd=run osmcfromsd; run osmcfromusb; run storeboot Could I change it to this: bootcmd=run start_autoscript; run osmcfromsd; run osmcfromusb; run storeboot And keep the abillity to boot to osmc and osmc recovery? I assume here that when a "run" command succeeds it does not continue to the next. Given that I set start_autoscript to the one in aml_autoscript.

That's right, I'm fine with only being able to boot armbian, although having the ability to boot other distros as well would be nice. But for now I'm happy if I succeed in booting armbian.

Thanks for your reply! Just to be sure that I don't mess it up, these are the lines in aml_autoscript: 1. VS�cA|�#AlJ�if printenv bootfromsd; then exit; else setenv ab 0; fi; 2. setenv bootcmd 'run start_autoscript; run storeboot' 3. setenv start_autoscript 'if mmcinfo; then run start_mmc_autoscript; fi; if usb start; then run start_usb_autoscript; fi; run start_emmc_autoscript' 4. setenv start_emmc_autoscript 'if fatload mmc 1 1020000 emmc_autoscript; then autoscr 1020000; fi;' 5. setenv start_mmc_autoscript 'if fatload mmc 0 1020000 s905_autoscript; then autoscr 1020000; fi;' 6. setenv start_usb_autoscript 'for usbdev in 0 1 2 3; do if fatload usb ${usbdev} 1020000 s905_autoscript; then autoscr 1020000; fi; done' 7. setenv upgrade_step 2 8. saveenv 9. sleep 1 10. reboot 11. 12. # Recompile with: 13. # mkimage -C none -A arm -T script -d aml_autoscript.cmd aml_autoscript Do I need to enter line 2 through 8 in the uboot environment?

I see some references to bootm, kernel.img and dtb.img in fw_printenv, so tweaking with that may pave the way to booting Armbian properly. However I'm afraid to brick the device in the process. I vaguely remember that it's possible to backup the bootloader, but don't have any experience. Any pointers?

I went the naive approach and just copied `Image` as `kernel.img` in the boot partition. The "Unable to read file kernel.img" went away and it said "** Unable to read file dtb.img **". So then I copied meson-gxl-s905x-vero4k.dtb to dtb.img. Now it logs the following: reading kernel.img 29127168 bytes read in 1578 ms (17.6 MiB/s) reading dtb.img 40983 bytes read in 5 ms (7.8 MiB/s) loaded DTB from SD avb2: 0 ee_gate_off ... avb2: 0 Wrong Image Format for bootm command ERROR: can't get kernel image! [rsvmem] get fdtaddr NULL! rsvmem - reserve memory I'm guessing the file format is not what it expects.

I reflashed Armbian on an SD card and booted while connected to UART. Then I inspected the difference between the boot logs. Below is the diff (right is with SD card). It looks like the SD card is recognized and an attempt at booting is made, but it's unable to read a kernel.img file.

Apparently I had the baud rate wrong, it should be 115200, which explains the gibberish.

Hi, I'm in a similar situation as I decribed in this post, so I'm following this thread with interest. Maybe we can help each other. The Vero 4k is a bit different because it has no Android image, only Linux. It does use U-boot and has indications of an Android boot image (maybe chain loading?), but I'm not yet clear on the details. Like you I've also tried several methods, but none seem to work. I'm now at a point where I connect via UART to inspect the boot process. However, I'm very new to this so I'm learning as I go along.

It's been a while, but I have some results. It was quite the journey, because I started learning to solder, but this job was way too advanced for me. Then a friend of mine very generously offered to do it and now I have successfully made contact via UART! The power is not provided via the 3V3 cable (after taking this picture I disconnected the yellow jumper and it still works), but I can imagine it's powered via the Vero device itself? The next step would be to find out what exactly what happens. I have no idea yet what the character string is, but I was pleasantly surprised I could just login to the Vero afterwards.

Thanks for following up and for your advice! I guess I have my work cut out for me. I'll try to find a way to solder those points to a UART connector and report back after.

I'm a complete noob on this, but I just looked up a tutorial online. Could this be the UART points? If so, that would be a very precise solder job: those dots are about 1mm in diameter.

Well, turns it did unclick after some more attempts. Nothing broke as far as I can see. Here's a picture of the insides: On the top right there's the toothpick button behind the audio jack.
