I've been trying to find the DRAM setting for this board. I found a firmware update that might help. Got it from androidpctv.com/firmware-transpeed-h618/ . I used the firmware unpacker from xdaforums.com/t/tool-imgrepacker-livesuits-phoenixsuits-firmware-images-unpacker-packer.1753473/ .
I used the Windows version of imgRePacker.exe to extract the boot0_nand.fex. Then read the boot0_nand.fex in linux using command hexedit boot0_nand.fex. It looks very close to the boot0 Andre Przywara used to find the DRAM settings on his board. lore.kernel.org/linux-sunxi/2123971.irdbgypaU6@jernej-laptop/ .
Not sure if this will work with our board. But if we can try these settings or find another firmware for our board. We might get past the DRAM setup errors.
