Hello guys, first of all thank you @jock, @fabiobassa and other people for this amazing rk322x project.
 
I ordered myself few of these cheap boxes. Few days ago one box came. It looks like that i got same box as @TU-Student
 
I read all the instructions and a lot of posts on this forum about how I should backup Android and boot Linux.
 
I understand that "Multitool" is the swiss knife, but for some reason this TV Box does not boot from SD card and the tool does not load, i only get orange LED on box and no signal (blackscreen).
 
I cannot test anything because box does not boot backup tool, and I cant backup eMMC/eMCP and try to flash Armbian build.
 
From what I have found this TV Box has:
SOC CHIP Rockchip RK3229 r0p5
WIFI CHIP AP6210
EMMC MICRON Q2J95T 8GB
RAM 1GB
 
It has fake android 7.1 (10.0), android kernel is very old 3.10.104, boots only at 720p resolution, but kernel and build itself is freshly made in 20230606 signed with test-keys.
 
What else can I do to make this boot from SD Card and load Multitool? How to make flash storage snapshot with android and flash armbian manually if  I cannot use multitool.
 
Please help
 
 
 
 
 
 
 

If it's a TV box, you might get better results in the TV box forum.
 
But some systems have the DTB embedded in the kernel image. If you can get to a shell, you can dump it from a running system sorta like:
 
dtc -I fs -o devicetree.dts /sys/firmware/devicetree/base  
Keep in mind that there are periodic changes to the DT format over time, and some vendors put in nonstandard hacks. Keeping these DTB files current is a major issue for Armbian devs. If it's for an unsupported box, it'll almost certainly require changes for everything to work properly.
