Ofgwrite fails to create bootpartion on SD card

[mihaip1948]

Tested on OpenATV 7.3 under Dreambox ONE.
I've create a SD card OpenATV 7.3 using Ofgwrite
... rootfs partition was created OK ! but Boot partition
event reported OK ! is bad and tge SD card does not boot !

[betacentauri]

What did you exactly do? Which command did you execute? Please attach ofgwrite log.
How is the SD card formatted?

As I have no Dreambox I cannot test.

The SD card was an old one used by Gemnini SD card image for Dream ONE !

• first partition FAT 32 Mb
• second EXT4
  I've tried also with clean partitions !

The boot partition isn't understood by OpenATV

I "solved" the problem ... leaving Boot partition "as is"
from Gemini and creating only the rootfs partition.
But the issue remains !!!

You can read it on my Forum translating from romanian !

[mihaip1948]

You can test this on any other STB ! Dreambox ONE is not relevant !
You must download Dream ONE OpenATV 7.3 from here 👍

http://images.mynonpublic.com/openatv/7.3/index.php?open=dreamone

it contains the Kernel and the rootfs you need ! then let Enigma2 to
mount your SD card and try to examine the partitions !

[betacentauri]

Maybe dream works different than other boxes. Is the boot partition from Gemini really FAT32 formatted? Can you mount it? If yes, which files are present?

Non Dreamboxes use a "raw" boot partition without filesystem. So the kernel will be written just into the device. Maybe this is the difference.
(By the way: ofgwrite was never developed for dreamboxes! Doesn't say it should not work there, but only to tell you, that it was never tested by me)

[mihaip1948]

No ! I don't think is different ! The boot partition should mountin Enigma2 because is an ordinary FAT16 GPT  one !  You-reright ... does not mount in Windows ! I can show how it looksin the case of Gemini-42-SD-card-image ! Pe duminică, 21 mai 2023 la 12:42:25 EEST, Betacentauri ***@***.***> a scris: Maybe dream works different than other boxes.

And if you use gemini kernel file and flash that with ofgwrite. Does that work?

Sorry, I need to know how gemini creates the kernel partition and how it fill it. Then I can maybe help.

[mihaip1948]

When I try to use the complete flshhing with "ofgwrite" as : ofgwrite -kmmcblk1p1 -rmmcblk1p2 /media/hdd/dreamone I have on a inseted USB stick the content of Open ATV installation files  as : The execution ends with "succes" but the boot partition type is "undefined"instead of FAT16 GPT ... and the SD card does not boot ! Can't boot becausethe bootloader assumes at FAT and mounted !!!

Please try to mount the fat16 boot partition (the one that works) in the dream box:
mkdir /tmp/b
mount /dev/mmcblk1p1 /tmp/b
ls -la /tmp/b
What is the output?

Ok, so a partition with filesystem which non dreamboxes don't have.
It includes a autoexec.img and a gemini.bmp. And something something with 10MB size.
The text formatting is very bad and some parts are missing. See here:
#18
Can you post it via browser and not via email?

OK ! I'm on the browser now !!!

Autoexec.img has in front some binary code !
then set the environments variables , displays
some image , witch can be changed ! and loads
the kernel and boot it ! Kernel is just the binary
code ... we have it !
I think is enough to expect SD card to be formatted as :

• FAT 16 GPT partition of some 32 Mb big enough to accommodate
  the Kernel witch is not greater than 20 Mb
• EXT4 GPT partition for rootfs

You must only copy into the boot partition the sample
autoexec.img , a bootlogo , and the Kernel as provided !
then unpack the rootfs into dedicated partition !
Eventually the user can supply his own bootlogo !!
Possible autoexec.img can be edited and eliminate
the display of a bootlogo !

Hi Betacentauri !
Can you add at the archive known types : .tar.xz ?
this is the extension for all DreamOS like images !

[betacentauri]

Can you add at the archive known types : .tar.xz ?

Please create new issue for it. It's possible, but not so easy as you might think and I have at the moment only very limited time for this. That's also why this issue isn't fixed yet.

Can you attach autoexeg.img here? Does dreambox two use the same one?
I don't really want to deliver bootlogo and several files with ofgwrite. Can you test whether it also works without bootlogo?

[mihaip1948]

This is the only public autoexec.img ! it comes with the SD card images released by Gemini Team.

Gemini is a development of DreamOS made by Dreambox !All Dream ONE and TWO are based on the same Kernel , theone released by Dreambox and kept secret at sources level !Some images are DreamOS OE 2.6 alike (Gemini ) othersOpenATV and PurE2 are trying to break the secrets !OpenATV is publishing the Kernel along with his rootfs !a good idea ! People are expecting a new Kernel from Dreambox !one to fit the new developments ... combo tuners an Dream Seven !
