No, is not. If you remove usb device, it will boot android. If put back usb, go to linux.

@sliver85 , I downloaded the image from: https://armbian.hosthatch.com/archive/aml-s9xx-box/archive/ Worked to me: - Armbian_23.02.2_Aml-s9xx-box_bullseye_current_6.1.11.img.xz - Armbian_23.5.1_Aml-s9xx-box_bookworm_current_6.1.30.img.xz Follow again these steps: 1) Burn SD (i.e. Balena Etcher) the above image 2) Mount and open that SD 3) Edit /extlinux/extlinux.conf and "FTD lines" with only "FDT /dtb/amlogic/meson-gxl-s905x-p212.dtb" (without quotes) 4) Copy (or rename) "u-boot-s905x-s912" root file to "u-boot.ext" 5) Create in that SD a ZERO BYTE file (i.e. "empty.zip"). SD is done. 6) Next step: Boot tv box normally (without SD) 7) In tv-box original Android, open "Update" app, select that empty zip file and click "update". This step unlocks boot from SD card 8)) Turn off tv box, insert SD card and turn on Try and give us a feedback

Great @thielj - USB "extlinux" folder: Update extlinux.conf: "FDT /dtb/amlogic/meson-gxl-s905x-p212.dtb" - USB root folder: Copy "u-boot-s905x-s912" to "u-boot.ext" - Create in USB device a zero byte file called "vazio.zip" ("empty" in portuguese) - In tv-box Android, open Update App and select above zip file and "update" On next boot, Armbian (bookworm) will start at USB device succesfully. THANK YOU

Sorry @Werner @stroma: "I managed to boot Armbian image from a usb flash drive." How do you get this? Solding wires and adb way? What about its perfomance comparing with RPi?
