If the cost isn't affordable and the company doesn't want to public all
source code, he can try this approach:
1. Enable userfs to move yaffs from kernel to userspace
2. Build yaffs as wasm module and run it in:

Hi Sebastien,
I think having YAFFS2 support on mainline will be very good.
Companies are free to decide if they want to use GPL code or not.
Many companies don't want to use it, but for some it is completely fine.
Xiang, I'm looking forward to test it. Please just put it dependent of
user enabl

I will just talk about some possible solutions for small companies. We
already pay the license from Aleph One which is very very cheap from my
point of view.

I am not confortable with NuttX having features that you have to pay for.
In this case yaffs should be provided as an external patch, but should
not be in mainline.
At the very least such features should not be advertised on public websites.
That is just my opinion but I find it good to bring

oh, I just found it:
"The fee depends on the number of distinct Products in which Yaffs
will be used, and there is a base price of GBP £10,000. If more than
one Product is included in the same Licence there is usually a
reduction in the second fee."
For a big company it is fine, but small compan
Also, sorry for the multiple messages, but why is that not new IOCTL
calls (used to "Support other, less frequently used commands") so the
structure is not modified ?
That would be a much more compatible way of doing things. Devices that
dont implement this would just automatically return -ENO

the callbacks are not activated by conditional compilation and are in
the middle of struct mtd_dev_s , so how are these optional?

Hi Xiang Xiao,
This is a great news, but I'm afraid yaffs is not a good option for
everybody because it uses GPL license.
But yes, it could be an option for people and companies that can
release all their software as open-source. PX4 project for example
could use it.

We are working on yaffs porting, mtd_s need a little bit of extension to
support NAND flash.
Here is the patch: https://github.com/apache/nuttx/pull/8670
LittleFS needs some modification to get the benefit.

Hi Michael,
In addition, if you want to load your elf directly to the memory mapped
flash storage, you need some flashloader for your debug tool. I can help
with segger's flashloader if that is of interest. (dsk)
