Power Up
The 4-pin power jack (P12) should be used to supply necessary DC power to the board.
WARNING
Turn off the main power for the RDB case before the power connector is
attached.
Power up the power supply. A few seconds after power up, the u-boot prompt => should be received by
the serial terminal program as shown here:
U-Boot 1.x.x (FSL Development) (Date - time) MPC83XX
Clock configuration:
Coherent System Bus: xxx MHz
Core: yyy MHz
Local Bus Controller: xxx MHz
Local Bus: yy MHz
DDR: xxx MHz

The normal function of the product may be disturbed by strong
electromagnetic interference. If so, simply reset the product to resume
normal operation by following the instructions in the manual. If normal
function does not resume, use the product in another location.

MPC8308_RDB Software
A board support package (BSP) is pre-installed on the MPC8308_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
MPC8308_RDB.
The MPC8308_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 MPC8308_RDB BSP release package contains a file named MPC8308_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
