[ELDK] How to Boot a New Kernal from TFTP Server

[Ashutosh Sharma]

Hello

Are you planing to boot using NFS or RAM disk.

In case of RAM disk you need to tftp ramdisk.img and kilauea.dtb files to ram.

in case of RAM disk use

=> bootm kernel_location ramdis_location kilauea.dtb_location
in case of NFS boot
=> bootm kernel_location - kilauea.dtb_location

Make sure to set bootargs for both before booting the system

Regards,
