Can I get a image of a neutrino?
My device has a dream 820 HD
I was able to play image Dream 8000 on my 820
But the image does not completely capture the interest
If you can help me get a complete image of my device
--
These are some patches
If possible, add it to the neutrino source

I don't have this box and I do not build blind a image. Also may not possible to build a DM820 image, because the full kernel sources/patches missing - same for DM800.

But your changes seems to be working except SIG/SNR, but they are only cosmetic, channels are found. The tuner configuration is strange with tuner A as Master and B as Independed - why? Is A Master then B Twin or Loop. Or set both to Independed if single signal cables.

Firstly, thank you for the response

The tuner was changed and a signal was obtained, but it was not complete either

As for the kernel patches
is here

Hmm... Seems this box uses a mmcblk* flash device (kernel config) and no NFI, complete different to DM800X. This may take a lot of time to change the GIT for build a "working" image. And I need some more informations (partions, how to flash, usb possible and so on). I have current late shift, so I can't change this the next days/weeks.

EDIT: The link has not the full kernel patches, some are missing. They was only avail at sources.dreamboxupdate.com, but the "new" server (dreamboxupdate.com/sources) is incomplete and has no kernel patches.

I must now go to work...

Thank you
take your time

I have build a kernel for testing, see attachment. But the dm820 ist strange, because the kernel is only valid at the rootfs.tar.bz2 in /boot and twice as gz and bin?! The kernel.bin (flash image from OATV) is empty ?!
I don't understand this box...

EDIT: Attachment removed.

dm820-kernel.tar.gz

I build on this oe-alliance-core naturally

Unfortunately, I do not have enough experience to guide you in correcting the matter
But I'm just an amateur

I have seen the original image at http://dreamboxupdate.com/opendreambox/ ... /index.php and they don't have a vmlinuz.gz*, only the uncompressed kernel vmlinuz.bin* found at /boot. And the flash file is a tar.xz. Means, the attached kernel should be working. Please check if modules loading.

But I think the file vmlinux.gz-rescue-3.4-r1-dm820-20200715.bin is the normal vmlinuz.gz, only renamed. But for what is this file? Is the name variable e.g. as vmlinux.gz-rescue-3.4-dm820-20240512.bin ? Hmm...

And what does
parted /dev/mmcblk0 print
shown?

This is a complete bootloader that has nothing to do with the image boot
It is downloaded to the device individually and sent to tmp
Then use the following commands

Code: Alles auswählen

flash-rescue /tmp/*.bin

It is closed source

I must go to work...

You have forgot the "print" at the end of the line.

parted /dev/mmcblk0 print

Then should all partions listet. Example hd51:

Code: Alles auswählen

hd51:~# parted /dev/mmcblk0 print
Model: MMC 4MEYMA (sd/mmc)
Disk /dev/mmcblk0: 3930MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:

Number  Start   End     Size    File system  Name     Flags
 1      1049kB  2097kB  1049kB               boot     msftdata
 2      2097kB  10.5MB  8389kB               kernel1
 3      10.5MB  978MB   968MB   ext4         rootfs1
 4      978MB   987MB   8389kB               kernel2
 5      987MB   1955MB  968MB   ext4         rootfs2
 6      1955MB  1963MB  8389kB               kernel3
 7      1963MB  2931MB  968MB   ext4         rootfs3
 8      2931MB  2939MB  8389kB               kernel4
 9      2939MB  3908MB  969MB   ext4         rootfs4

And, does the kernel working?

I apologize
Prefer the output

Code: Alles auswählen

root@dm820:~$ parted /dev/mmcblk0 print
Model: MMC SEM04G (sd/mmc)
Disk /dev/mmcblk0: 3959MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags: 

Number  Start   End     Size    File system  Name    Flags
 1      75,5MB  1074MB  998MB   ext4         rootfs
 2      1074MB  3959MB  2886MB  ext4         data

root@dm820:~$

EDIT by BPanther: Full quote removed.

Hmm, strange box. Where is the kernel stored? And what is in partition 2 ("data")? The box has 4 GB Flash, but only 1 GB used for root. No extra space for kernel. Or is the kernel at a "old flash type" how /dev/mtdX?
What is the output of

cat /proc/mtd

The hd51 has nothing.

Code: Alles auswählen

hd51:~# cat /proc/mtd
dev:    size   erasesize  name
hd51:~#

Or maybe same as a "real" linux, kernel and root in 1 partition.

I can try to make some changes for building, but I can't test anything and a online update will also not possible because I don't know how yet.

cat /proc/mtd

Code: Alles auswählen

root@dm820:~$ cat /proc/mtd
dev:    size   erasesize  name
mtd0: 01000000 00010000 "entire_device"
mtd1: 00100000 00010000 "bootloader"
mtd2: 00f00000 00010000 "recovery"
root@dm820:~$
