on your Linux host PC as explained in Section 2.1. Now go inside the following folder
$(TOP_DIR)/$(RFS_TOP_DIR)/scripts/. In this folder you will find file rfs_install.sh, open this
file and edit following variable in this file.
KERNEL
= Set kernel path
RFS = Set RFS source top directory path
ARCH = Set the architecture type
Now run “scripts/rfs_install.sh [kernel_type]” at $(TOP_DIR)/
