Ethernut 5.0 Hardware Manual

Quick Start

This chapter will help you quickly set up and start usin the Ethernut board.

Prerequisites for Operation

Ethernut 5.0 boards are shipped with samboot boot loader pro rammed in internal

Flash memory, U-Boot boot loader, Linux kernel and a sample Nut/OS application

pro rammed in serial Flash memory and a Linux root file system pro rammed in

NAND Flash memory.

The followin items are included in the Ethernut Starter Kit:

•Ethernut 5 Board

•Turtelizer 2 JTAG pro rammin adapter

•Crossed serial communication cable with DB-9 female connector at both ends

•USB cable Type A to Mini B

•CD with all required software tools and documents

•This manual

To run the Ethernut Board, you additionally need:

•A standard PC runnin Linux, Windows or Mac OS X with serial COM port, USB

port and Ethernet interface

•Terminal emulation software, such as MiniTerm (Linux) or TeraTerm or

Hyperterminal (Windows)

•Twisted pair cable to ether with 10/100 Base-T hub or switch

For power supply the followin options are available:

•Connectin the Ethernut board to a USB port of your PC.

•Usin an unre ulated DC power supply providin a minimum 1.5 Watt at 7V,

but not more than 24V (preferably 12V) on a standard 2.1 mm barrel plu .

•Usin an IEEE 802.3af capable Power over Ethernet switch.

It is further assumed, that you ot some basic knowled e about di ital hardware,

Linux or Nut/OS and TCP/IP networkin . This manual will not present any of these

basics. You can find excellent books or web resources about these topics.

Precautions

Born out of an Open Source Project, the Ethernut Board itself is a commercial

product you paid for. You expect, that reliable and fail safe operation is uaranteed

by the manufacturer. But please keep in mind, that a bare electronic circuit is a

fra ile product, which demands careful handlin . In the first place learn how to

avoid problems caused by electrostatic dischar e.

Be sure to take proper precautions before removin the Ethernut board from the

antistatic ba . When not used, put the board back into the antistatic ba . Never

pass the bare board from one person’s hand to another.

Ethernut 5.0 Hardware Manual

Do not use the antistatic ba as a underlyin pad for Ethernut, because it’s

electroconductive. Plastic surfaces may be harmful too because of electrostatic

dischar e. It is advisable to put the board at least on a wooden surface or simply

on a piece of paper. The optimal way is to fix stand-offs in the mountin holes.

Board Installation

Step 1: Remove the board from the antistatic ba . Visually inspect it for any

dama e made durin shipment. If there are visible defects, return the board for

replacement.

Step 2: Connect Ethernut`s DB-9 RS232 port to an available COM port usin the

serial cable included in the starter kit. Any null-modem cable should work as well.

Step 3: On the PC, start the terminal emulation pro ram at 115200 baud, no

parity, 8 data bits, and 1 stop bit. Disable hardware (RTS/CTS) and software

(XON/XOFF) flow control.

Step 4: Use one twisted pair cable (patch cable) to connect Ethernut's RJ-45

connector to the hub or switch. Make sure that the PC is connected to the same

physical Ethernet network. Ethernut 5.0 comes with Auto-MDIX and may be

connected directly to the PC with a standard patch cable. However, dependin on

the PC's operatin system, link ne otiation may not work reliable in this

confi uration.

Step 4.1: If not connected to a PoE switch, you can use the USB cable for power

supply. Connect the Mini-B connector to the Mini USB receptacle on the Ethernut

board and the Type A connector to any USB port of your PC.

Step 4.2: Alternatively you may connect an external 7-24V, 1.5W power supply

to the barrel connector on the Ethernut Board. Ethernut is equipped with its own

rectifier brid e. Therefore the polarity of the barrel connector isn't important.

As soon as the board is powered up, the red LED at the reset switch will be lit.

Then the SAMBoot boot loader firmware will initialize the hardware and move the

U-Boot boot loader from serial Flash memory to the SDRAM and start it. U-Boot

messa es are displayed in the terminal emulator.

See the next chapter for a detailed description of the boot loader pro ram.

WARNING: As with all computer equipment, the Ethernut board may be severely

dama ed by electrostatic dischar e (ESD). Be sure to take proper precautions

before removin the Ethernut board from the antistatic ba . Do not hand the bare

board to another person.

Quick Start

Usin the Boot Loader

As soon as the board is powered up, the U-Boot boot loader will send several

status messa es to the serial port, which are displayed on the terminal emulator.

Hit any key to stop autoboot:

In the default confi uration, U-Boot will wait up to 3 seconds for any key entered

via the serial port and then continue to boot the Linux kernel from serial Flash. If

any key is pressed, U-Boot will display the command line prompt, waitin for a

command. Enter help and press Enter to display the list of available commands.

U-Boot> he p

More detailed informations about most commands are available by enterin help

followed by the specific command, e. .

U-Boot> he p usb

Beside the build-in commands, U-Boot is able to execute command scripts, which

are stored in environment variables. The command printenv lists the contents of all

environment variables.

U-Boot> printenv

Ethernut 5.0 Hardware Manual

Scripts stored in environment variables can be executed by enterin the command

run followed by the variable's name. The variable bootcmd contains the script that

is executed durin automatic bootin .

U-Boot> printenv bootcmd

bootcmd=run f ashboot inux

This simple script calls another script contained in the variable flashbootlinux,

which will boot the Linux kernel from serial Flash. You may alternatively boot

Linux from a TFTP server by chan in the bootcmd.

U-Boot> setenv bootcmd run tftpbootlinux

U-Boot> saveenv

Saving Environment to SPI F ash...

SF: Detected AT45DB321D with page size 528, tota 16.5 MiB

Erasing SPI f ash...Writing to SPI f ash...done

The command saveenv will store the modified environment in serial Flash, makin

it available on the next power-up.

Several predefined scripts are available to boot Linux or Nut/OS or to update Flash

contents:

run flashbootlinux Boot Linux kernel from serial Flash.

run flashbootnut Boot Nut/OS ima e from serial Flash.

run nfsbootlinux Boot Linux kernel from NFS mount.

run nfsbootnut Boot Nut/OS ima e from NFS mount.

run nfsinstallenv Update U-Boot environment in serial Flash from NFS mount.

run nfsinstalllinux Update Linux kernel in serial Flash from NFS mount.

run nfsinstallnut Update Nut/OS ima e in serial Flash from NFS mount.

run nfsinstalluboot Update U-Boot in serial Flash from NFS mount.

run tftpbootlinux Boot Linux kernel from TFTP server.

run tftpbootnut Boot Nut/OS ima e from TFTP server.

run tftpinstallenv Update U-Boot environment in serial Flash from TFTP server.

run tftpinstalllinux Update Linux kernel in serial Flash from TFTP server.

run tftpinstallnut Update Nut/OS ima e in serial Flash from TFTP server.

run tftpinstallrootfs Update root file system in NAND Flash from TFTP server.

run tftpinstalluboot Update U-Boot in serial Flash from TFTP server.

When usin an NFS or TFTP server, make sure to properly set the variables

nfsserver or tftpserver. The U-Boot documentation will provide further details.

Bootin Linux

When not interrupted by pressin any key, U-Boot will load the Linux kernel from

serial Flash. Alternatively you can enter the command boot on the U-Boot

command line.
