Hello,
Yes, the inability to write individual bits in already programmed
sectors is a HUGE constraint. We have flash like this in some high
security embedded products, and it required a full redesign of our flash
interface.
Wear leveling is doable, but the particular bit that made us think

There is some brief information about dhara here:
https://github.com/dlbeer/dhara . It is an FTL that provides many of the
features described previously:
* Wear leveling,
* Hardware/software EEC
It does not appear to do
* Bad block detection
* Marking of bad blocks
The nicest thing is th
I found the discussion in the thread "W25Nx NAND flash support"
I think they gave up submitting support after some bad criticism from a
user!

Unfortunately NuttX is full of "hidden features", that is something that I
try to avoid during the code view:
All new features needs proper Documentation/
I think YAFFS was discussed here sometime ago, but I don't remember all the
details.
I had the impression that

Seems like dhara.c was integrated into mainline, but they didn't submit
support to YAFFS (if I remember correctly it was because YAFFS requires
license payment for commercial usage).
There no references to either under fs/.
The YAFFS website is not responding. This is what I get about licensin
Thank you Greg for clarifying!
I think Xiang Xiao and guohao15 also worked with NAND recently (DHARA and
YAFFS).
Seems like dhara.c was integrated into mainline, but they didn't submit
support to YAFFS (if I remember correctly it was because YAFFS requires
license payment for commercial usage).

I did test the FS's that were available and they mostly worked on these
platforms. I could actually run nxffs and smartfs for a l
Hi Saurav,
AFAIK, the only MCUs with NAND Flash controllers supported on NuttX are
samv3 and sama5.
Mr. Greg Nutt implemented it for Atmel about 10 years ago, but if I
remember correctly, he never got it well tested because there is no FS for
NAND on NuttX.
I think if you decide to use an SPI NA
Hi all,
I'm working on creating a file system for NAND Flash for NuttX as part of
GSoC '24. I would be thankful of any suggestions that you might have for
the type of board that I should use and the NAND flash as well.
Thank you in advance.

Saurav Pal
