MPC8313E RDB Software
A board support package (BSP) is pre-installed on the MPC8313E RDB. This BSP consists of a bootloader
(U-Boot), a generic PowerPC Linux-based system, and an associated file system. U-Boot, the Linux
kernel, and the file system reside in the on-board flash memory. At power up, the Linux system runs on
the MPC8313E RDB.
The MPC8313E RDB BSP generation takes advantage of a tool called the Linux Target Image Builder
(LTIB). LTIB is a suite of tools that leverages existing open source configuration scripts and source code
packages and bundles them into a single BSP-generation package. The source code packages include boot
loaders and Linux kernel sources as well as many user-space source code packages to build a complete
BSP. LTIB also provides compiler packages required to build the BSP. Freescale developers use LTIB to
create BSPs for a multitude of Freescale development targets. LTIB leverages as many BSP elements as
possible for all Freescale-supported targets, and it offers the flexibility to customize components that
require platform-specific modifications.
The MPC8313E RDB BSP release package contains a file named
MPC8313E RDB-<yyyymmdd>.iso
. This file
is an ISO image that can be burned to a CD-ROM or mounted directly from your hard disk. Note that
<yyyymmdd>
is the release creation date. The LTIB installation script that installs all necessary packages on
a host Linux PC and allows you to modify the BSP and packages within the BSP is in the
/ltib-MPC8313E-RDB
subdirectory within the ISO image.
This ISO image contains a file called
Readme.txt
that describes how to generate and install the BSP on the
MPC8313E RDB hardware platform.
Readme.txt
contains the latest information for each BSP release. The
ISO image also contains
Release Notes.txt
, which describes changes to the current BSP version versus
earlier releases. To rebuild the BSP package or to add application software, carefully follow the
instructions in
Readme.txt
. This file contains details on how to build, run, and install the BSP. It guides the
