I already got some "late night success" 🎉 Thanks to the work from @granitr in the following thread I could already successfully boot the stvm8b using the default meson8b-onecloud.dtb Currently it just seems that WIFI is not (yet) working – HDMI output worked directly from the beginning. I will keep everyone posted here on my progress 🙏

Maybe we can bundle our effords regarding a working S805 image? I also have hundreds of new TV sticks (not boxes) with an Amlogic S805 (Meson 8B). The original Android ROM has the codename stvm8b. Currently I only have a working Android 4.2.2 image with a patched kernel for real 1080p output which can be flashed using TWRP onto the internal eMMC. I really would love to get some kind of more recent and non-Android image up and running. It's a real struggle to get any custom images as most links are dead already which makes it more complicated. Currently I have full UART access to the device and I'm able to interact with the uBoot shell. I also see the full kernel output of the working Android image and have a root shell there. But as others already pointed out kernel 3.10 is way to old to be used in production. So "porting" a more recent kernel would be great. My main goal is to get a Linux image up and running on the box which makes it still useful as device for digital signage or as a small webserver.

The device should be the same like the ODroid C1 Would love to participate in the process of creating a useful image for the S805 platform and especially for this piece of hardware.

I'm not sure if that helps but your log says "** Unable to read "dtb.img" from mmc 0:1 **" – so the dtb cannot be read from mmc and it is using the fdt instead: "Booting using the fdt blob at 0x11800000" So maybe the hardware cannot be initialized correctly because of a wrong / missing dtb?
