SD Card in Simulation
Hello,
I am working on a system that uses an SD card to read various files.
I am also using the simulator for testing this firmware.
I would like to test the parts of the system that read and parse these
files, so I need a way to simulate the SD card.
Is there any way to achieve this?
Ideally, I would like to mount a directory of the host system directly in
NuttX.
Or maybe select a set of files to be included in compile time?
Thank you!

Hostfs is exactly what I need. Thank you!

Hi
The closest way to achieve this, eg if you want to exercise the SD
drivers, would be to simulate a SPI/SD device that the main SD driver
could talk to.
The simulated SPI or SD would have to get,recognize and execute SD
commands, and it would get its storage from the host disk or memory.
This is a bit cumbersome, so if only a more functional file storage is
required, romfs or hostfs could be enough.

Hi Fotis,
you use the ROMFS feature to include files directly on the image … it depends on some external tool called ‚genromfs‘
You may check for ROMFS and ROMFSETC in the configuration and documentation.

You can try HostFS.
