Problem flashing on a Miracelbox MBtwin #12

original-birdman · 2021-09-28T00:01:27Z

I'm trying to (couch) flash a build of the Python3 build of OpenVix.
The image build has completed OK and I have this:

[mbtwin]: unzip -l openvix-5.5.015.005.developer-mbtwin_usb.zip
Archive:  openvix-5.5.015.005.developer-mbtwin_usb.zip

 --------                     -------
107654185                     5 files

but when I try to couch flash this ofgwrite starts up, then the screen goes blank and nothing further happens.

The syslog is reporting (lots of) this error:

Sep 27 23:59:43 mbtwin user.warn kernel: !!!Error BERR_OS_ERROR(0x6) at /home/peteru/Source/T3/inihdx/device/refsw_release_97405_20110228/nexus/../magnum/basemodules/kni/linuxkernel/bkni.c:622

If I reboot the box at this point it boots back to the previous image (indicating that no flashing took place at all?)

If I take a full image backup of the current (Python2-based) system and couch flash that all is OK.
That image is:

[mbtwin]: unzip -l myimage-developer-5.4.015.006-20210927_234440.zip

125829242                     6 files

so it doesn't look as though it's an image size issue (as this one is larger)

Any ideas as to what the problem actually is?

Hmmmmm.....I can (now) see an oddity in the Py3 image build.

The kernel.bin is not a multiple of 512.
Could this be an issue???

betacentauri · 2021-09-28T05:56:14Z

Is the ofgwrite “GUI” visible on the TV screen?

You could try doing this:

Login via telnet. Execute this:
tail -f /var/log/messages
Then start flashing via ofgwrite.
Post log from Telnet window.
Try to flash the image via USB. Does this work?

What is that?Looks like it belongs to a Beyonwiz T3.

original-birdman · 2021-09-28T10:07:05Z

The GUI starts up, the first "block" is filled in on the top progress bar - then the screen goes blank.

At this point it is looping and filling the messages log with that error message.

The command being run is:

root      1245     1 10 Sep27 ?        00:00:18 /newroot/ofgwrite_bin -r -k /media/usb/imagebackups/imagerestore/miraclebox/twin

original-birdman · 2021-09-28T10:08:06Z

What is that?Looks like it belongs to a Beyonwiz T3.

It's a Miraclebox MBTwin. Which, IIRC, is very similar.

betacentauri · 2021-09-28T10:24:32Z

Can you please execute this in Telnet:
ofgwrite -n -r -k /media/usb/imagebackups/imagerestore/miraclebox/twin
(Edit: This is one line)

This won’t flash your box (because of -n switch), but it maybe shows the problem. Please post the output.

original-birdman · 2021-09-28T10:41:02Z

That finds nothing wrong...

It's a Miraclebox MBTwin. Which, IIRC, is very similar.

"peteru" is a Beyonwiz developer and "T3" is a Beyonwiz model so no clue what that is doing in mbtwin build.

original-birdman · 2021-09-28T10:59:05Z

Similar paths are mentioned through the dvb.ko file. Possibly he was involved in compiling it (10 years ago)?

Anyway, it's the same file that gets used when successfully flashing my Py2-Vix made backup.

betacentauri · 2021-09-28T15:19:54Z

Please flash the image via USB to confirm that it works.

Do you have a serial cable for the box?

original-birdman · 2021-09-29T01:20:06Z

Please flash the image via USB to confirm that it works.

It does. Slow, but it gets there and then I can boot into the Py3 version of OpenVix.

Do you have a serial cable for the box?

No.

betacentauri · 2021-09-29T16:47:33Z

And if you first stop e2 and then flash from telnet?
So first:
init 4
And then same command like above, but this time without the -n.

original-birdman · 2021-09-29T19:22:13Z

I actually tried a reflash of the image (from my now-running Py3 Vix) and that also failed (screen blanked shortly after the "start").
When I manually reran the command it produced:

^C^C^C

That ^C^C^C is me trying to get out of it, but it's hung (looping in the kernel).

Again, it hadn't actually flashed anything, as a power off/on brought back my Py3 Vix.

However, one further wrinkle.
I created an image backup of my Vix Py3 installation.
This one couch flashes fine (and takes me back to where I was...).

So it seems to be something specific to that one image file(?).

original-birdman · 2021-09-29T19:37:44Z

So, a quick recap.

openvix-5.5.015.005.developer-mbtwin_usb.zip
An image file produced by the Vix build process. This can be USB flashed, but cannot be flashed using ofgwrite in either 5.4.014.006 (Py2) or 5.5.015.005 (Py3)

myimage-developer-5.5.015.005-20210929_192243.zip
An image file created by the ImageManager on the running 5.5.015.005 (Py3) system. This can be flashed by ofgwrite on my running 5.5.015.005 (Py3).
EDIT: But has since FAILED on a bare install of 5.5.015.005 (Py3) after a USB flash an no restore of my settings/plugins.

original-birdman · 2021-09-29T19:42:12Z

And I've found out what the problem is!!!

The build process produces an image file that contains splash.bin, but the backup process does not.
And if I unpack the build image, remove splash.bin and rezip it, then ofgwrite is happy with it.

So the problem is related to the splash.bin.

Now, I do remember some time (years?) ago that the original OpenVix start-up splash banner went away and was replaced by a plain miraclebox one. Perhaps there is something wrong with the box that means the splash "location" is now non-writable?

betacentauri · 2021-09-29T19:51:21Z

Ofgwrite don’t use splash.bin.
And it don’t unzip the image zip. That does e2.

I still don’t understand how this can cause problems…

betacentauri · 2021-09-29T20:01:20Z

According to the log it might hang while opening the framebuffer. Is not 100% sure but this is one of the steps after the last log message.
In the other open issue here from technic he also has problems with the framebuffer.
I don’t understand why this happens. These kind of errors were not present in the last months/years…

original-birdman · 2021-09-29T20:09:45Z

OK. Having got the system to flash without the splash.bin I was left with a bare system. So I tried couch flashing my Py3 backup (which had worked earlier this evening).
That failed this time.
So there seems to be something odd and random going on?
