The problem is that the H9 (and a few other boxes originally designed for android) don't use a standard GPT table in flash, but something specific for android which is not native to Linux.

 

The restore looks for specific partitions in the GPT to restore the backup to, but those can't be found. We're looking into a way to get Android partition table support built in, but that won't be a quick fix (imho).

 

And there is no android for it so I could test the android on it

Yesterday I spend some time to analyze which data is stored on the emmc memory which is visible in linux.
The /dev/mmcblk0 don’t have any MBR or GPT. I don’t know how Linux knows that the emmc memory contains several partitions. I guess it’s built into the kernel. So no way for me to find rootfs and kernel partition.
I guess driver devs need to create a /proc/mtd or /proc/emmc which can be read.
Or we use fix devices for the boxes, which wouldn’t be very nice.

[Erik Slagter]

Indeed, afaik Android doesn't use real partitions, a shame.

[betacentauri]

h9 uses ubi filesystem:

root@h9:~# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00100000 00020000 "boot"
mtd1: 00100000 00020000 "bootargs"
mtd2: 00100000 00020000 "baseparam"
mtd3: 00100000 00020000 "pqparam"
mtd4: 00100000 00020000 "logo"
mtd5: 00100000 00020000 "deviceinfo"
mtd6: 00800000 00020000 "trustedcore"
mtd7: 01000000 00020000 "kernel"
mtd8: 0e200000 00020000 "rootfs"

This looks good. ofgwrite should be able to flash that box. You only need uImage and rootfs.ubi files, which are included in the image zip file.

[betacentauri]

@Persian Prince: You can also create a kernel.bin instead of a uImage file. That doesn't matter.

Don't use the sumo branch, it is very much WIP and completely untested.

[foxbob]

I understand that this is a test branch, but it’s necessary to check.

[WanWizard]

Yes, eventually. But currently is it way to early, we're still busy trying to get everything compiled. None of the images that can be build have even been flashed yet.

[Persian Prince]

I understand that this is a test branch, but it’s necessary to check.

As far as it's not merged into develop, not necessary for me or you but if you care contribute yourself, don't expect support for a WIP branch please.

No it is not.

 

The sumo branch is a feature branch which eventually will take the develop branch to sumo. That is something completely different than "a branch meant to build sumo from". Never build from feature branches.

 

As it happens I have rebased the sumo branches the last about 20 times, so it will have messed up your building environment quite badly, anyway.

Any news about a fix for backupsuite for H9 series ? Now that new H9 models are introduced....

[betacentauri]

I can only say that latest ofgwrite supports h9 if the box uses ubifs(my does but I don’t know whether all h9 boxes have that).
New OpenPLi version with this ofgwrite version will be released in near future.
Don’t know whether the plugin needs adaptions.
Which files does the plugin create?

[Dimmie]

The backup seems to be made correct.

 

The problem is that when you want to flash the backup with backupsuite, it doesn't work.

 

Screen becomes black, then after some minutes the box restarts but you still have your old image, so nothing is flashed.

Edited by Dimmie, 30 October 2018 - 18:25.

[betacentauri]

The black screen problem is fixed in new ofgwrite version, but also with black screen flashing worked for me. Maybe ofgwrite version is too old in the 6.2 release or something else.

Please test with attached new version. Unzip the file and put it into /usr/bin/. Please be sure that the file is executable (should be when you overwrite the existing file).

With the ofgwrite file replaced it gives the screen for flashing but at the end you get error: "error flashing rootfs" and it says that the box wil restart in 60 seconds and that it won't boot anymore.

 

But... >> the box restarts and boots fine, but nothing happened, the image is not flashed, it just restarts in the 'old' image.

[betacentauri]

No more information on the tv screen?
At which step does it happen?

[littlesat]

Sounds more the image you tried to flash was invalid...

[betacentauri]

Good point. But until now we "only" had rootfs.tar.bz2 files which were corrupt and no ubifs file.

I think it's better to switch for debugging to PM.

[Dimmie]

The image was made with the same backupsuite.

 

It first says flashing kernel. Then after a while (80% or so) you get this message in red letters.
