-USB Host Configuration
-^^^^^^^^^^^^^^^^^^^^^^
-
-The NuttShell (NSH) Nucleus 2G configuration 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.
-
