[RAUC] One more question about RAUC

[RAUC] One more question about RAUC

[Manuel Duran Flores]

Hello RAUC company!

I have only one more question about RAUC.

First of all, many thanks for your last reply!

Regarding Enrico's answer , and the problem of Adaptive update vs NAND 
FLash. In the last email, Enrico told a solution of this problem exists, 
although it could be more complicated. So I need to know if I could have 
access to this solution, because in the blog there is only a link to 
contact you. So, do I have to contact you that way to see the solution? 
Can you give me an URL?

I'm assuming this is all free, from what I've read RAUC is pure open 
source, but I could be confused.

I hope you can help me. Thanks a lot !!

Kind regards,

Manuel

You are welcome, but, is there a specific reason why you open a new thread? One benefit of mail
Communication is that you can have conversation threads and cite answers for reference and context.

To make this transparent, I guess you refer to this mail:

The Pengutronix blog post you reference is:

https://www.pengutronix.de/de/blog/2022-10-12-rauc-adaptive-updates.html


The note from my mail was:

Where I refer to this box note in the blog post:

| The block-hash-index method does not work with NAND / UBIFS yet.
| 
| If an adaption for NAND is required, feel free to contact us or to discuss and contribute via GitHub.

I would assume that this already clearly stated it but: there is NO ready solution hidden somewhere.
We have just thought about what would be required technically to add support for this.

Thus the two solutions are either to hire Pengutronix (or any open source consulting company) to
implement this for you or to implement this yourself with the aid of the RAUC community and
contribute it back.

For the latter (or anyway), a good starting point should be to open a GitHub Discussion or an RFE
Issue where you describe your needs since GitHub is our primary tool for tracking the project.

This is true and also soft copyleft as enforced the (LGPL) license.
But since it is meant to be FOSS, new features only make it into the mainline project if someone
contributes them to the project.

I hope I could clarify some aspects.


Best regards

Enrico
