Obviously there is a problem with I/O on the mmc, perhaps not fully supported by the current kernel. Have you tried other images?

Only different versions of Ubuntu Server. On kernel 4.16, it can't see the emmc at all, but from a Balbes150 post I read, I think emmc install doesn't work on 4.16. On kernel 3.x, it all works fine, including emmc install.

Yes I get the same from fdisk on my box, but GPARTED does not see the partitions and therfore Linux does not either. SO, does gparted see the partitions on emmc?

 

Sorry about that. Here is the output of "parted print list,all" (It's ubuntu server so there is no gui)

To address your last issue first, I have also experienced some images where video output never comes back after screen is turned off due to timeout. It seems to be a general issue with newer kernels.

 

Now on 905x boxes the install.sh script does not work and there is no way to install to mmc. Period. On S912 it should work, are you able to access the internal partitions? Does Gparted see them without reporting errors?

Extracting dtb from Android firmware does not work either.

If by internal partition you mean the the emmc blocks, then yes. This is the output of "fdisk -l"

Greetings. I have two issues, and I would be equally grateful if either could be solved:

 

1) I have a T95Z Plus with an s912. I'm running Balbes150's Ubuntu Server 16.04 kernel 4.9. After boot, the system is able to recognize the emmc,  and /dev/data exists, but when I run the install.sh script, when it gets to "copy USR", it starts to hit a bunch of segmentation faults and a few bus errors, and eventually the system freezes up and I have to reboot. I'm using the gml_q200_2g.dtb from the dtb folder.

 

2) I have an X96 Mini with an s905W, running the same image as above. The system cannot at all recognize the emmc, and /dev/data does not exist. The output of "fdisk -l", "lsblk", and "ls -al /dev/block" all only recognize the boot device (my usb drive). I'm using gmx_231_1g.dtb from the dtb folder. I'm aware that it isn't the correct dtb file, but strangely it is the only one that will boot. I have extracted the dtb from firmware but it didn't work.

 

Bonus Issue) On the T95Z Plus (the first one), right from boot, the video output stops, and does not come back. I used an hdmi to dvi adapter on my monitor. It isn't a big issue because I'm able to ssh to it, but if anyone has a solution it would be appreciated.
