2.4 The PHYTEC phyCORE®-LPC3180

The phyCORE-LPC3180 supports the industry's first 90nm ARM-9 based microcontroller. The new

32-bit MCU high-performance, low power LCP3180 ARM926EJ-S device from NXP Semiconductors

(founded by Philips) is the only ARM9 microcontroller that provides a vector floating-point co-

processor and integrated USB OTG, as well as the ability to operate in ultra-low-power mode down to

0.9V. The on-board MMU supports many embedded operating systems. Other chip-level features

include 7 UARTs, SPI, I2C, a real-time clock with a separate power domain, and NAND Flash and

DDR memory controllers.

Please refer to the phyCORE-LPC3180 Hardware Manual for specific information on board-level

features, jumper configuration, memory mapping, pin layout, and carrier board features.

2.5 LPC3180 Boot Process

The LPC3180 boot process is a multi-staged effort involving one or more boot loaders. After a reset

the LPC3180 executes its on-chip bootstrap software located in the on-chip boot ROM. The bootstrap

software first looks at the latched value of the GPI_1/SERVICE_N signal of the MCU and either (1)

copies code from NAND Flash into internal RAM and executes it, or (2) attempts a data download

over UART5; if no code is received within the timeout period, booting proceeds from NAND Flash as

outlined in (1). Configuration of the boot mode is done via an external jumper on the phyCORE-

LPC3180 Carrier Board. By default the Carrier Board should be configured for boot process (2).

Please refer to the PHYTEC phyCORE-LPC3180 hardware manual for details on changing this

setting if required.

When booting from NAND Flash the on-chip bootstrap software copies the boot image located in

block 0 of the NAND Flash into internal RAM and executes it. For operation of Linux this boot image

must be the SIBL secondary boot loader. SIBL will initialize the SLC NAND controller and SDRAM.

After initialization SIBL will scan the NAND Flash for images and executables and load these into

memory. The first executable it finds, which in our case is U-Boot, will be executed. U-Boot will then

start Linux.

Besides starting Linux, U-Boot (Universal boot loader) is a feature-rich boot loader that can be used

to boot Linux in a number of different configurations (from Flash, from TFTP download, etc…) More

information on U-Boot can be found on the Internet or by typing help in U-Boot.

Getting Started

3Getting Started

What you will learn with this Getting Started example:

•installing Rapid Development Kit software

•interfacing the phyCORE-LPC3180, mounted on the Carrier Board, to a host-PC using the

Segger J-LINK

3.1 Installing Rapid Development Kit Software

3.1.1 Installing PHYTEC Spectrum CD

The current version of the PHYTEC Spectrum CD for ARM7/9 does not provide a setup program for

automatic installation of the LINUX specific kit contents1. You will need to manually copy the demos,

manuals, and other support documents for this Rapid Development Kit to your local hard drive.

•Insert the PHYTEC Spectrum CD into the CD-ROM drive of your host-PC. The PHYTEC

Spectrum CD should automatically launch a setup program.

•Please exit the installation screen.

•Open a Windows Explorer (or similar program) and browse to the PHYBasic\pC-LPC3180 folder

on the PHYTEC Spectrum CD-ROM.

The pC-LPC3180 folder within PHYBasic contains the following directories:

The Quickstart folder contains this QuickStart document L-698e_1.pdf

The Linux folder contains the ARM Linux tool chain, Linux BSP source code, file system,

Linux BSP documentation from NXP, and demo images required for this QuickStart.

The Manual folder contains the phyCORE-LPC3180 Hardware Manual

Copy the three folders listed above to your local hard drive in a location named C:\PHYBasic\pC-

LPC3180. Make sure to remove the read-only attribute from all files copied to you hard drive.

Note: All path and file statements within this QuickStart Instruction are based on the assumption

that you choose C:\PHYBasic\pC-LPC3180 as the default path when copying files from the

Spectrum CD-ROM to your hard drive.

1: Future versions of the Spectrum CD will offer automatic installaion for LINUX kit contents in the

same manner as currently available for KEIL and IAR kit versions.

It is important that you use the most recent version of the Segger J-Link drivers. PHYTEC

recommends installing the J-Link driver and jlink.exe from the Spectrum CD for ARM7/9.

•In a Windows Explorer (or similar program) browse to the C:\PHYBasic\pC-LPC3180\Segger

folder (or the same location on the PHYTEC Spectrum CD-ROM) and run the file

Setup_JLinkARM_V368b.exe.

•Follow the installation steps on the screen.

•Once the installation is complete jlink.exe can be found at the following installation location:

C:\Program Files\Segger\JLinkARM_V368b. jlink.exe will be required for flashing images as

described in section 3.3 of this QuickStart manual.
