9.2.3 Control the installation process using parameters
With Yocto version 25.0 and above it is possible to add paramters to the update-script call. This can be used to
control the update process, add files and install additional features.
The options available are:
-b|--BS Boot script
-d|--DTB Device tree
-f|--FS Root file system archive
-i|--Image Boot logo
-o|--OS Kernel image
-p|--ParamFile Parameter file (each parameter on a separate line)
-r|--RPM Additional RPM packages
-t|--TFTP Additional file (Format: <filename>:<target> )
-u|--UserPartition User partition (Format: <filesystem>:<megabytes>:<label> , supported filesys-
tems: vfat, ext2, ext3, ext4)

!
FLASH-N-GO:/ export TFTP=192.168.1.100; curl tftp://$TFTP/fng-install.sh > /tmp/a.sh;
sh /tmp/a.sh --Image=my-logo.png

located in the TFTP server directory.
--Image=my-logo.png
--OS=custom-linuximage.bin
