Hi Saurav,
Amazing! I'm happy to know you fixed it!
If you can create some board configuration or document how you are doing
it, I think it will be useful for more people here!
Some years ago Ken Petit created a small Flash Simulator to use with
SmartFS, but I think this one you are using is dif
Hi Alan,
I have figured out the cause...it was because of a very *small* error in my
rawwrite method which was confusing littlefs (which I think commits CRC,
flushes it and rechecks the written data for consistency at one point in
the forceformat operation).
Right now, mount() works as intended.
Hi Xiang and Alan,
Thanks for the info Xiang.
Alan, the first error returns ENOTTY as littlefs sends a BIOC_FLUSH command
in IOCTL which isn't supported in NAND, and Xiang has provided the
explanation on why that is fine.
As for the -ENOSPC, I'm looking into it currently. It *should *have enough
Hi Saurav,
I suggest you to verifyr these errors first:
*Command: 1293 | BIOC_FLUSH: 1293*
Error Upper! ioctl | -25
#define ENOTTY 25 /* Not a typewriter */
So, you can search where this ENOTTY is returned.
Some to:
nx_mount: ERROR: Bind method failed: -28
nsh: mount: mount failed: 28
#defin
BIOC_FLUSH is used to flush the cache which may exist in mtd driver to
guarantee the power-loss resilience. It's optional, so it's enough that
mtd_nand returns -ENOTTY.

Hi all,
I've been trying to develop a device simulator for the NAND flash (in the
sim).
A short note on what this does is create a virtual NAND flash (from RAM)
and provide a driver, as well as a wrapper around the upper half (which for
now, does nothing extra). This helps in creating records of
