14.7.1. LITE5200 Installation Howto
A nice "Application Note: Installing Embedded Linux on the Motorola MPC5200 Lite Evaluation Board"
which covers the installation of U-Boot and Linux can be found at:

14.7.2. USB does not work on Lite5200 board
Question:
USB does not work on my Lite5200 board. Also, the green LED behind the USB connector remains
always off. Why?
Answer:
This is a hardware problem. The green LED must be on as soon as you power on the Lite5200 board.
As a workaround you can short-circuit resistor R164 (bottom side of the board, close to the USB
connector). Please note that you will probably lose all warranty and/or may ruin the board. You have
been warned.
15. Glossary
ABI
- Application Binary Interface
The convention for register usage and C linkage commonly used on desktop Power Architecture® machines.
Similar, but not identical to the EABI.
Includes binding specific ppc registers to certain fixed purposes, even though there may be no technical
reason to enforce such binding, simplifying the process of linking together two separate sets of object code.
e.g the ABI states that r1 shall be the stack pointer.
BANK
- also "memory bank"
A bank of memory (flash or RAM) consists of all those memory chips on your system that are controlled by
the same chip select signal.
For example, a system might consist of one flash chip with a 8 bit bus interface, which is attached to the CS0
chip select signal, 2 flash chips with a 16 bit bus interface, which are attached to the CS1 chip select signal,
and 2 SDRAM chips with a 16 bit bus interface, which are attached to the CS2 chip select signal.
This setup results in a system with 3 banks of memory:
1 bank of flash, 8 bit wide (CS0)•
1 bank of flash, 32 bit wide (CS1)•
1 bank of SDRAM, 32 bit wide (CS2)•
