[ptxdist] Extra args to mkfs.ubifs with new image creation options

[ptxdist] Extra args to mkfs.ubifs with new image creation options

[Guillermo Rodriguez Garcia]

Hi all,

I am trying to switch from the "legacy" ptxdist image creation options
to the new system based on genimage. This is because I want to
generate an ubi image out of three separate volumes, and the legacy
approach does not support this very well.

I am still trying to see how it all works; first issue I have found
is, how to specify extra arguments to mkfs.ubifs? In particular I need
to add --space-fixup; however I don't see any place where I could
configure this with the new system.

Any hints?

Did you already find the genimage docs? Look for pengutronix at
GitHub. genimage works with config files, everything is set there.

ptxdist ships those genimage config files in folder 'config/images'
and you can "overwrite" those in your BSP as you would do with rules.

Thanks for the pointers! Now I see how to customize existing configs.
What is the proper way to add new targets?

For example in my case -- I want to generate a ubi image out of
three separate volumes; one of these is the rootfs volume which is
already supported out of the box. How to add new targets for the
additional volumes, so that ptxdist "notices" they need to be built?

The genimage README documents an extraargs option for
"Extra arguments passed to mkubifs". Would this work for you?

Cheers

Yes. The missing bit is that I was not sure where to add these extraargs.
But Alexander's reply already pointed me in the right direction.
