nfidump is now available since >3 years and since then there was always a working version available.

 

I didn't start the misuse of nfidump to support clones, so they are now stuck with old binaries lacking all new functionality like lzo compression or ubifs support and should not complain about the consequences.

 

And yes, I'm fully aware that is is a simple =m in the kernel config file to build the nandsim kernel module which means everybody with an up-to-date OE can build it themselves.

 

That's the reason why I'm a little bit dissapointed that we now have to collect modules from dubious sources instead of getting properly built standard module from the Feed of the image.

 

But when I'm dissapointed I stop complaining, I start acting

I would now be ready, but we still miss lots of nandsim modules for various boxes:

 

>>>>>>>>>>>> nfidump 0.10.0 by gutemine <<<<<<<<<<<<

based on code from tmbinc, noggie and others

extracting UBI image ...
extracting root image ...
extracting root with ubifs via nandsim ....

>>>>>>>>>>>> nfidump 0.10.0 finished <<<<<<<<<<<<<<<
 

On my dm8000 it now works nicely to extract root_cfe_auto.bin via nandsim module, hence I'm pretty sure that it will work also on your boxes.

 

Get the modules, then you get the testkit.

We now started preliminary NP tests on the VU boxes, anybody having ET/CT box and already found a matching nadsim module and wants to get the preliminary kit for early bird testing, then write PM.

 

But you have to hurry, because if everything works as expected I'll publically post the testkit late this evening.

 

And I can only support 2-3 users via PM, so don't be dissapointed if you volunteer but have to wait until then.

 

Testinstructions are simple - install nandsim ipk so that modprobe nandsim works, then install nfidump 0.10.0 ipk and then copy some DMM Images and some extracted ZIP images for your and other boxes to a directory of your harddisk like /hdd/backup

 

Then it is a simple nfidump /hdd/backup/imagename.nfi /hdd/backup/extractdirectory or /hdd/backup/xxx/root_cfe_auto.bin /hdd/backup/extractdirectory in telnet and we see if it works.

 

If it doesn't work I need the telnet output.

OK, so let's give it a try ...

You should not only download, you shout try out and report back if it works as it should

 

If it fails I need the telnet output and maybe the dmesg output.

 

And don't report any FATAL: nandsim not found errors , then you didn't install the nandsim module so the modprobe nandsim failed ...

some nandsim modules

 

more soon

[Lost in Space]

Nandsim modules for dreambox are NOT neaded as the dreamboxes running ubifs all have block2mtd driver in kernel so there is NO need to install it. Only when block2mtd is not found nandsim will be used and hence needs to be installed and due to the great wisdom of your devs you have to get them on your own.

Thanks, so it looks like Uno s not using 512 subpages from the 2048 byte blocks.

 

Remember, I have to develop/test this on an dm8000, because it also has 2048k Blocks in Flash, BUT it uses subpages.

 

Is any of your boxes using subpagest at all, because if not, then I will simply disable it ?

 

But we now have almost 40 downloads, and so far I only know that it works on sol2 to and not (yet) on uno, any further inputs ?

 

Coould you try to unpack a solo2 image on the uno with nfidump 0.10.0 so that we see if it then cashes also ?

 

Could you try also unpacking an DMM image on the uno ?

On Merlin extract the process has hanged - a forced reboot was the only solution to get rid of the process.

It freezes on every 2/3 nfidump extraction tries.

dmesg attached.

Could you try to add -v 2048 to the nfidump command, eg.

 

nfidump -v 2048 /hdd/backup/xxxx/root_auto_cfe.bin /hdd/backup/imagedir

 

This enforces the blocksize at the ubiattach, maybe it helps, becuaset he crahes in nandsim driver are always caused by wrong allignment.

 

At least you now know why I prefere block2mtd and spent so much time to make it run.

 

And uno is not that great on the memorysize - I run a permanent swapfile on all my boxes, maybe I will have to add at least a temporary one to the nfidump binary too.

 

Does the hanging/crash stop if you mannually add a swapfile ?

Looks like I had this feature only in the development kits. I'll re-enable it, because it allows to unpack images where auto detection fails.

Sorry for letting you wait, but I had a busy week.

 

Attached is a Version 0.10.1 of nfidump

 

Now the -v option for the vid header offset option should also work.

 

But normally this should not be needed

 

Please continue your tests with the attached version!

Unfortunately again segmentation fault. Now i`m not sure if this not caused by missing swap, same as you already pointed out by you.

I`m not gonna be available as a testing person for the weekend. Maybe someone else could help ?

[Lost in Space]

The segmentation fualt is not the point, the point is the reason why - if it is again due to wrong ubiattach commands then dmesg should tell the full story.

 

And I didn#t fix the segmentation fault, I just fixed the -v option so that we can try out if it is avoidable and with which parameter.

 

But I'm patient, if people don't want to have a feature and don't help to get it I will not push them.
