I lowered RAM clock to 648 MHz (taken from Android boot log). It's only 12 MHz difference, but may be important.
If this still doesn't work, boot Android, execute busybox devmem 0x3006100 over serial console and tell me what value you get.
Flashed that image, but still doesn't work.
Enter in serial console and executing the command give me :
I was able to get boot.img, but extraction give me errors.
Little clarification, boot to android without connected HDMI
chocho can you somehow extract DTB file? I usually do that from box image, but I can't find any for TX6 mini on the net. As last resort, you can make clone of eMMC to some external media like USB using dd, compress it and upload somewhere.
chocho I'm not able to find DT file. Can you check if /sys/firmware/devicetree/base exists? If so, it's binary version of device tree, which can be easily decompiled.
Yes, there it is, but for what to look :
:/sys/firmware/devicetree/base # cd

#size-cells n_brom/

chocho While that helps, it would be even better if you can upload /sys/firmware/fdt file somewhere.
Lets try to upload it here :
One question. Is it fdt file actually the device tree ?
Because I was able to convert it with dtc
yes it is. I'm comparing it to Tanix TX6 now, but till now I didn't find any important difference.
I noticed that DRAM parameters are very different. I will have to go over them and check what might cause the issue.
chocho box uses "Half DQ" DRAM configuration which is not implemented yet. Are you willing to test images in order to fix this? Hopefully only a few tries should be enough.
Yes, I will test your images.
And thanks for support !

If it doesn't work, some more text should be printed. I'm interested what it says. If it works, I'm interested if appropriate amount of RAM is detected.
@jernej Unfortunately it doesn't work. Here is the boot lines:
U-Boot SPL 2019.04 (Jun 28 2019 - 23:15:46 +0200)
DRAM:This DRAM setup is currently not supported.
resetting ...
U-Boot SPL 2019.04 (Jun 28 2019 - 23:15:46 +0200)
DRAM:This DRAM setup is currently not supported.
resetting ...If you want compile only u-boot and I'll flash it on top on this image.
chocho Here is new U-Boot: u-boot-sunxi-with-spl.bin
Burn it with sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdX bs=1024 seek=8 where /dev/sdX is your SD card device.
chocho Please wait, I figured few other things. I'll prepare another U-Boot.
