[ptxdist] Where to find parameters for UBIFS creation

[ptxdist] Where to find parameters for UBIFS creation

[Ivor Kruger]

Hi, I want to create a ubi image from my NFS root mount folder.

I will use mkfs.ubi.

Where can I find the settings that ptxdist uses for creating the ubi fs
files, since these work perfect?

Thanks in advance
Ivor

For the correct UBI image layout run the tool "mtdinfo" on your target.
$ ptxdist menuconfig
   Shell & Console Tools --->  
     <*> mtd-utils --->
         [*]   ubi utils  --->
             [*]   mtdinfo

You shouldn't use the NFS root directory as the base of your UBI image. Let 
ptxdist create this image instead. In the latter case ptxdist ensures the 
correct owners and permissions of the files inside the UBI filesystem.

If you are using the old way to create a UBI image, you can find the current 
parameters in the platform menu ("$ ptxdist menuconfig platform" -> image 
creation options).
If the new way to create a UBI image is used, you can find the settings 
in "configs/<your-platform>/config/images/<some-name>.config"

Juergen

Actually, let me rephrase my question slightly:

Where can I change the flder that is used to create the images from when
the command "ptxdist images² are used.

I can then just set that folder to my modified NFS root folder and run the
command normally.

Thanks

You can't. The folder is generated on the fly in a fakeroot with the proper
ownership and permission. This is done for good reasons. Just packaging the
NFS root folder can cause all kinds of problems.
You should create proper packages that install you files correctly and then
use the normal mechanism to create the images.

Don't do that. That doesn't work twice. If you need to change something in the 
NFS directory to make your target happy, you should store these changes into 
your BSP. Then you will be able to create this working image again and again 
whenever you need it.

In order to avoid having to do this, what is the easiest way to add a user
application to the root/home folder?
Where do I add custom init.d scripts to get them as part of the image?

You can build this application as a generic package like all other packages as 
well. That's the main goal of PTXdist.

> Where do I add custom init.d scripts to get them as part of the image?

$ ptxdist newpackage file

This will generate a rule file to simply copy new files into the image.

But if you just want to replace a generic (=already provided by PTXdist) file 
by your own specific version, just store your specific version into your 
BSP's "projectroot/<regular-path>/<specific-file>"

PTXdist will prefer the local file the next time the corresponding package will 
be generated.

Juergen

Jurgen, that sounds easy enough, thanks. I will give it a try on my next
build.

Hmm, you know how long the life cycles of interim solutions are? :))

Does it actually make sense to speak of "life cycle" when it comes to 
things that are bound to last forever (like interim solutions usually do)?

Lol, the software really is only interim, it was to take the device
outside for some sunlight readability tests.
