+USB Host Configuration

+^^^^^^^^^^^^^^^^^^^^^^

+

+The NuttShell (NSH) Nucleus 2G 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 nucleus2g/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.
