Armbian for H313 X96-Q LPDDR3 TV-Box

[Nick A]

Your tv stick probably has secure boot enabled. You can compile a secure boot image using these steps.

Nice! I'll try that. Thank you for your help so far. Finding the right documentation has been a little tricky for me and I really appreciate the help.

Alright, I built the x96q-lpddr3 image using the patches suggested. It booted (partially). Nothing on the screen, but it is starting!
I chose that image because it is H313 and lpddr3 (the android uboot build that worked before detected it as such)
I attached the serial log. It's getting late here and I may not get much more done on this until Monday, but this is a good sign in my opinion.

H313/H616/H618 are pretty much the same SOC. It’s the AXP power management IC that’s different. Also RAM and WIFi chips are usually different.

Cool, good to know. I'll try one with the same AXP and go from there.

[Randlin]

Hmm, according to the config, the X96q lpddr3 uses the AXP313 already. Maybe ram is wrong? Pretty sure it's lpddr3, if there is any way to check that, I can. Gonna do a little digging in android.

According to Android uboot, DRAM_VCC= 1200mv
DRAM CLK =648 MHZ
DRAM TYPE=7 (lpddr3)
DRAM SIZE =1536 MBytes, para1 = 30fa, para2 = 6001000, dram_tpr13 = 26061
gonna try some of this in the x96q image, see what happens

Hmm, in boot log I see AXP1530 mentioned in theandroid boot (booted off the sd card, not emmc). I attached the log.

bootinfo.txt

[Randlin]

I set the dram speed to 648, no difference. Gotta be the axp or another option.

[Nick A]

AXP1530 is the same as AXP313a. Take a look at the link I posted above. 
 

You could use this tool to extract your dram settings from an android update or boot0.bin.

sunxi-fw info -v boot0.bin

Will do

[Randlin]

uboot-config-dump.txt Here it is

[Randlin]

I did notice in the log:
INFO:    PMIC: Probing AXP305 on RSB
ERROR:   RSB: set run-time address: 0x10003
INFO:    Could not init RSB: -65539

[Randlin]

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

[Randlin]

/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

@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.

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

[Randlin]

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

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 data.

 

also that’s not the android dts you posted. It has some info but not all of it.
