USB Host Configuration
^^^^^^^^^^^^^^^^^^^^^^
The NuttShell (NSH) mbed can be modified in order to support USB
host operations. To make these modifications, do the following:
1. First configure to build the NSH configuration from the top-level
NuttX directory:
cd tools
./configure mbed/nsh
cd ..
2. Then edit the top-level .config file to enable USB host. Make the
following changes:
CONFIG_LPC17_USBHOST=n
CONFIG_USBHOST=n
CONFIG_SCHED_WORKQUEUE=y
When this change is made, NSH should be extended to support USB flash
devices. When a FLASH device is inserted, you should see a device
appear in the /dev (psuedo) directory. The device name should be
like /dev/sda, /dev/sdb, etc. The USB mass storage device, is present
it can be mounted from the NSH command line like:
ls /dev
mount -t vfat /dev/sda /mnt/flash
Files on the connect USB flash device should then be accessible under
the mountpoint /mnt/flash.
