Appears to be fully functional.
12. Using USB Device as a Mass Storage for the host computer:
System Type --->
STM32 Peripheral Support --->
[*] OTG FS
Device Drivers --->
[*] USB Device Driver Support --->
[*] USB Mass storage class device --->
[*] Mass storage removable
[*] RAM Disk Support
Board Selection --->
[*] Enable boardctl() interface
[*] Enable USB device controls
File Systems --->
[*] FAT file system
[*] FAT upper/lower names
[*] FAT long file names
[*] PROCFS File System
Application Configuration --->
System Libraries and NSH Add-Ons --->
[*] USB Mass Storage Device Commands --->
(/dev/ram0) LUN1 Device Path
Compile and flash the firmware in the board as usual, then in the nsh:
nsh> mkrd -m 0 -s 512 64
nsh> ls /dev
/dev:
console
null
ram0
ttyS0
nsh> mkfatfs /dev/ram0
Connect a USB cable to STM32F4Discovery board (connector CN5) and run:
nsh> msconn
mcsonn_main: Creating block drivers
mcsonn_main: Configuring with NLUNS=1
mcsonn_main: handle=1000a550
mcsonn_main: Bind LUN=0 to /dev/ram0
mcsonn_main: Connected
In this moment a 33KB disk should appear in your host computer. If you
saved some file on this small disk you can now run disconnect command:
nsh> msdis
msdis: Disconnected
Remove the USB cable from microUSB connector and run:
nsh> mount -t vfat /dev/ram0 /mnt
nsh> ls /mnt
/mnt:
TEST.TXT
nsh> cat /mnt/TEST.TXT
