#341969 Jack the Ripper - PLi Special Edition for UBIFS Conversion of PLi OE 3.0 Images

Posted by Lost in Space on 1 April 2013 - 22:14

Yes, and I pray for world peace too!

 

To come back to the topic of this post - so far nobody complained about problems with JTR (which is pretty amazing for one of my plugins) or about any problems with the resulting images.

 

Thanks for all the downloaders and testers!

 

Happy Eeaster!

#341733 Jack the Ripper - PLi Special Edition for UBIFS Conversion of PLi OE 3.0 Images

Well, maybe this is part of the answer - ubifs is simply faster!

 

And if you read the bugfixing list of the drivers - why live with old drivers and old loaders and their bugs ?

 

And JTR is NOT mixing any drivers it uses the complete /lib/modules of the latest DMM Image - if you install there what you need it will be put fully operational into the Ubifs PLi Image. Off course it will not upgrade, but you can always repeate the procedure if a new kernel and drivers come out.

 

ALL the Drivers from DMM for their new OE 2.0 are experimental, so where is the point to use older ones ?

 

But the reason for JTR is not so much about newer drivers or kernels. For running UBIFS you simply NEED them as with the old ones UBIFS will not work (except on the 8000).

 

With the DMM kernel in Flash suddenly you also have working block2mtd drivers and can extract all ubifs and jffs2 images with nfidump without any problems.

 

PLi doesn't support any Multibooting, but with such a kernel in your PLi Image  you can now use it in Flash and Multiboot ALL other DMM OE 2.0 based images.

 

And finally - to find out if it runs smootly, the easiest and most efficient way is to RUN it, isn't it ?

 

And now everybody has the freedom to decide, and look and see him/herself...

 

Happy Easter!

#341663 Jack the Ripper - PLi Special Edition for UBIFS Conversion of PLi OE 3.0 Images

Dear Boardmembers!

 

On 'special request' of Erik Slagter I created a Special Edition of the Jack the Ripper Plugin.

 

The original JTR is able to convert Non-Dreambox Images from VU+, CT,.. to Dreambox nfi Images which are then flashable and behave almost like a normal Dreambox image.

 

The JTR Special Edition is now able to convert OpenPLI OE 3.0 Images to the latest kernel and drivers from DMM and their root filesystem to UBIFS.

 

Usage is quite simple, install the latest OE 2.0 Experimental Image from DMM to your dreambox (you can get one from www.opendreambox.org) or if you want to enjoy also the etra features of my initramfs Patch like Label mounting then get the latest OoZooN Image from www.oozoon.tv. and flash it.

 

Then you install in this image the attached ipk and after an enigma2 restart you have the JTR PLI Special Edition Plugin in your Plugin List.

 

On Blue in the JTR Plugin you may change UBIFS root file compression (default is zlib for 800se and 500hd to save space, and favour_lzo for the 8000 and 7020hd) and the location of your image backups - default is /media/hdd/backup and it always has to be a subdirectory of a mountpoint.

 

After reading the Disclaimer on Yellow you can start Conversion of an up.to-date OE 3.0 OpenPLI*.nfi Image for your box that you copied to the above backup directory.

 

After 5-10 minutes Jack the Ripper will have converted a new UbifsPli*.nfi for you in this directory.

 

If there are problems please post me the /tmp/jtr.log which is created during conversion.

 

The created nfi image can be then flashed in the normal ways (DreamUP, Bios WebIF or even with dFlash) to your Dreambox and you will enjoy the latest DMM drivers, kernel and a root UBIFS Filesystem in your PLi Image.

 

After Flashing an booting your UBIFS PLI Image your root first line of a df -h should look like this (sizes depend on the Dreambox you have):

 

root@dm7020hd:~# df -h
Filesystem                Size      Used Available Use% Mounted on
ubi0:rootfs             374.2M     43.7M    330.4M  12% /

 

And don't be too scared from space problems, as your images are already pretty small, but be aware that UBIFS needs about 10% more space, but even on a 500hd after conversion almost 6MB are still free.

 

The Plugin was tested on my 500hd, 8000 and 7020hd, but if you find bugs or have problems using it feel free to ask for help.

 

If you want to know what ubifs is, how it works and what it is good for on your Dreambox, please check first this article in the Dreambox blog before asking the questions answered there already:
