examples/usbstorage
^^^^^^^^^^^^^^^^^^
This example registers a block device driver, then exports the block
the device using the USB storage class driver. Configuration options:
CONFIG_EXAMPLES_USBSTRG_NLUNS
Defines the number of logical units (LUNs) exported by the USB storage
driver. Each LUN corresponds to one exported block driver (or partition
of a block driver). May be 1, 2, or 3.
CONFIG_EXAMPLES_USBSTRG_DEVMINOR1
The minor device number of the block driver for the first LUN. For
example, N in /dev/mmcsdN. Used for registering the block driver.
CONFIG_EXAMPLES_USBSTRG_DEVPATH1
The full path to the registered block driver. Example, "/dev/mmcsd0"
CONFIG_EXAMPLES_USBSTRG_DEVMINOR2 and CONFIG_EXAMPLES_USBSTRG_DEVPATH2
Similar parameters that would have to be provided if CONFIG_EXAMPLES_USBSTRG_NLUNS
is 2 or 3.
CONFIG_EXAMPLES_USBSTRG_DEVMINOR3 and CONFIG_EXAMPLES_USBSTRG_DEVPATH3
Similar parameters that would have to be provided if CONFIG_EXAMPLES_USBSTRG_NLUNS
is 3.
