OMAP3EVM # setenv bootcmd 'tftpboot 0x80000000 uImage;bootm'
This configuration boots a new Linux kernel via TFTP with a NAND flash based file system
3. The initenv-samsung.txt and initenv-micron scripts provide the options for setting the bootargs for the
appropriate target file system that is being used for the boot. Kindly refer to the appropriate script files
for the flash parts that is being used on the board for more details. In case of use of ramdisk file
system use the following commands:

You could use TFTP to transfer the ramdisk image from the development PC or flash it on the NAND
flash. Refer section 5.4.2, Running the Re-flash Procedure for more details on flashing the file
systems on the target
NOTE: Currently there is no full ramdisk image that includes OMAP3530 DVSDK demonstrations.
In case of use of NFS, use the following commands:
