7. μClinux Startup Scripts
Introduction
Various startup scripts are called during the Linux boot process. These initialization files are
found in the build environment under
<install directory>/linux/vendors/Lantronix/<platform>/romfs_extra/.
Edit them as appropriate.
/etc/inittab
The /etc/inittab file controls the configuration for the init process. It is here that the various startup
and shutdown scripts are configured, and the console device is specified. The default /etc/inittab
file is setup so that /etc/init.d/rcS will be called at startup.
/etc/init.d/rcS
The /etc/init.d/rcS script is responsible for mounting the target’s file systems, and calling the next
stage of initialization scripts.
/etc/start
The /etc/start script is called by /etc/init.d/rcS. It calls the /etc/netstart script to initialize
networking, and various other scripts if they are present. It also calls dBUG-config to reset the
boot failure counter which was previously incremented by dBUG.
