configured as Flash Disk. To find out the file system information,
please use command /mount as shown as below. In addition, use
command /df to find out the disk space of the disk. The
RAMDISK uses 8MB SDRAM space to store the root file system
and 8MB for uboot loader and Linux Kernel Therefore it is about
16MB free SDRAM for user application software. The image of
Linux kernel and root file system is stored in the flash memory
and it uses about 4MB flash memory space and the rest of 12MB
