hexdump got a reaction from armar in Armbian for TV box rk3328
@armar - yes with the -I or -O fs options you can also use a device tree structure as input or output for the dtc command - it then works exactly like a dtb file with the -I or -O dtb options.
@Sico - your edited dts file looks right - the last easy option is see would be to set the dmc-opp entry (memory voltage and frequency scaling) for opp-600000000 and opp-800000000 from disabled to okay like in your dts, but i guess it will not help much neither. opp-hz should not really differ between the dts files, except for the higher disabled clocks by me.
if all that does not help, i would suggest you get some pl2003 usb to serial adapter and solder a serial console to your board (only gnd, rx and tx - usually tx from the board to rx of the adapter and the other way around). this way you will be able to see the bootup messages and get an idea about what really is the problem. one thing to be aware is that the baud speed of the serial console is 1500000 for rockchip devices instead of the usual 115200.
good luck - hexdump

hi @armar - the above device-tree-copy.tar.gz is the android dtb, just in another format and read from the system in an easier way
@Sico - your hardware is definitely different from the 4g/32g t9 hardware - atttached is the resulting android dts file for your box - what you can do is: take my rk3328-t9.dts file from above and change all the opp-microvolt* values in the various sections to the values in your dts file and then build your dtb from it on a linux machine with the command "dtc -I dts -O dtb your-modified-rk3328-t9.dts > rk3328-t9-2g.dtb" and try this dtb then. you might need to install the "device-tree-compiler" package on your linux system for this.
good luck and let me know about the result and post the resulting rk3328-t9-2g.dts and rk3328-t9-2g.dtb files here in case it works.

with this diff against rk3328-evb.dtb for the 4.4 rockchip kernel i got mmc, serial console and the usb2 port working for a t9 rk3328 box (4/32g) and i think the h96max+ is similar, so maybe it will work there too - the resulting rk3328-t9.dtb and .dts are attached as well. @balbes150 if it works for others too it might be worth to include it into future rk3328 tv box images maybe.
