Well, there is also needs for storing data in a device that is not "ejectable" such as flash memory on PCB.

Btw, do you know of any FAT32 implementation suitable for tiny microcontrollers, i.e. no posix available?

@niclas @jeancf @lupyuen FatFs <http://elm-chan.org/fsw/ff/00index_e.html> is a portable implementation that even goes up to exFAT; we use it a lot in @RIOT_OS.

@chrysn

Thanks.... That was a lot faster than google... 😉

@jeancf @lupyuen @RIOT_OS

@niclas @lupyuen @RIOT_OS If rust is your thing, I wrote a bare metal driver for FATFS for the Sipeed Longan Nano that uses a lot of embedded-hal traits and should therefore easily portable.
