Definitely an option!
Still need a good way to get data on and off easily from
Windows/Linux/Mac but a copy-on-write type file system is more than
adequate for this product - thanks for the suggestion :)

Now I have RNDIS working on Windows (Linux a work-in-progress) I am back
to thinking of the best way forward. If anyone has further thoughts on
the following I'm very interested:

The protocol is not complex, but it requires many HOST<->DEVICES integrations.
I started a MTP implementation some years ago, it was enable to be
detected to Linux as a media device, but I didn't finish the
implementation to file transfer.
If someone get enough motivation and want to suffer a
Are there any implementations of MTP using NuttX, or that could be
easily and legally ported?

Perhaps the emails in question have been waiting on a human moderator? I
I think there is some issues in the Apache Foundation email infra,
this is the second time it happens. The same email is send again after

In the past I have put the FAT in a SPI Fram and the clusters went to a SPI
nor flash.

Some time ago TizenRT (a NuttX fork) added Journalling support to SmartFS.
We couldn't get it from them in the past because they changed the
License to Apache, but now that NuttX is Apache license maybe it is
possible to bring it to NuttX:
FAT itself definitely is not suitable for your task.
You need a journaling (log-structured) file system.
Alternatively, FAT can be used as a container file system for the
target journaling file system you like. E.g. you can format your Flash
by FAT, then pre-write a dummy solid file to the FAT

There is MTP (https://en.wikipedia.org/wiki/Media_Transfer_Protocol),
