usbnsh:
------
This is another NSH example. If differs from other 'nsh' configurations
in that this configurations uses a USB serial device for console I/O.
Such a configuration is useful on the stm32f429i-disco which has no
builtin RS-232 drivers.
NOTES:
1. This configuration uses the mconf-based configuration tool. To
change this configuration using that tool, you should:
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
and misc/tools/
b. Execute 'make menuconfig' in nuttx/ in order to start the
reconfiguration process.
2. This configuration does have UART1 output enabled and set up as
the system logging device. To use this UART, you must add an
external RS-232 line driver to the UART1 pins of the DISCO board
on PA9 and PA10 of connector P1.
usbmsc:
------
This is an example of enabling the FS OTG port on the DISCO board for
mass storage use. It provides an NSH session on UART1 to allow
accessing the connected USB mass storage device. Such a configuration
is useful on the stm32f429i-disco which has no onboard SD card or mass
storage solution.
NOTES:
1. This configuration uses UART1 as the system console. To use this
UART, you must add an external RS-232 line driver to the UART1 pins
of the DISCO board on PA9 and PA10 of connector P1.
2. The mass storage device will appear as /dev/sda and supports FAT
formatted "thumb" flash drives with:
