|

This configuration is used to mount a FAT/FAT32 SD Card into the OS' filesystem.
|
||||
It uses SPI to communicate with the SD Card, defaulting to SPI3.
|
||||
|
||||
The SD slot number, SPI port number and minor number can be modified in ``Application Configuration → NSH Library``.
|
||||
|
||||
To access the card's files, make sure ``/dev/mmcsd0`` exists and then execute the following commands::
|

|

nsh> ls /dev

nsh> mount -t vfat /dev/mmcsd0 /mnt
|
||||
|
||||
This will mount the SD Card to ``/mnt``. Now, you can use the SD Card as a normal filesystem.
|
||||
For example, you can read a file and write to it::
|
||||
|

nsh> ls /mnt

/mnt:

hello.txt
