From chapter 5.5.1 to 5.5.3, ramdisk boot-up sequence is commonly used.
5.5.1. Installing LMP
LMP boot-up using the ramdisk image and lmp-installer script on the ramdisk image
should be used to install all LMP deliverables (U-Boot, kernel, dtb, and rootfs). The
script considers redundant parts of the each device. All primary and secondary part can
be installed or upgraded using this script.
Run tftpboot on lmp U-Boot, like below.
After LMP Linux boot-up using ramdisk image is completed, edit and run lmp-installer
on linux, as shown below. Ipaddr / serverip need to be changed according to your
environment. lmp-installer downloads all image files from tftpserver, and install those to
proper locations.
