Actually in that post it was about downloading the boot_a partition. Then extracting the dts.. you can skip the dts extraction part for now. We need your boot_a partition. also that’s not the android dts you posted. It has some info but not all of it.

Oh, so it is the devicetree of Linux we want. My bad. Here it is: devicetree.txt FYI I was able to use binwalk -e on the boot partition dump, nice to see there is another way. Thanks for all the help

This post should help extracting your boot.img from android. That’s if your box is already rooted.

/sunxi-fw info -v fulldisk.img @ 0: mbr: DOS MBR protective MBR, GPT used GPT version 00010000 usable disk size: 7419 MB number of partition entries: 17 @ 16: toc0: signed boot image 2 items size: 98304 bytes @ 321: toc0: signed boot image 2 items size: 98304 bytes @26812: fit: U-Boot FIT image fit:__overlay__: "<no description>" fit:__overlay__: "<no description>" fit:fragment@2: "<no description>" So I never dumped just boot0 (and no firmware update available), but I have full emmc dump named fulldisk.img. I would assume it is the toc0? Trying to extract does not work , however: (maybe because there are two?) /sunxi-fw extract -v -n toc0 -o uboot0 /home/Tr/fulldisk.img unknown image file extracting the mbr works fine though.

Wait, that was the Linux kernel, not uboot. I'll get that
