7 Objective/Introduction 1.0 Objective/Introduction This document describes how to setup an ethernet connection between an Intel IQ80310 evaluation platform board (IQ80310) based on Intel XScale microarchitecture (ARM* architecture compliant) running RedBoot* and a host computer running Windows*. Step-by-step instructions explain how to: Set up the IP address. Perform ping tests from both target and host platforms. Issue RedBoot commands via Telnet*. Run the GNU debugger GDB over the ethernet connection. Captured screen shots help explain the procedures. The procedures assume limited prior knowledge of RedBoot, GBD or Telnet. A trouble shooting section addresses some problematic issues you may encounter while performing these procedures. Application Note 7

A host computer system with an available PCI slot or......the Cyclone* PCI backplane (PCI BP) and power supply. The serial cable provided with the Intel IQ80310 Developer Kit. Either an ethernet crossover cable or......two standard ethernet cables and an ethernet hub. The RedBoot GNU/Microsoft Windows CD provided with the IQ Figure 1. Ethernet Connection Components 8 Application Note

9 SettingupIPAddressandPort 3.0 Setting up IP Address and Port First make sure the latest firmware is on the IQ80310, the latest Flash of RedBoot can be obtained from: Under the section: Flash Recovery Utility (FRU) Self-building FRU Disk File Manual-build FRU Disk File Intel Flash Recovery Utility (FRU) Reference Manual Select FRU Self-building File, and follow the instructions to extract the files to a local drive and then create the disks. 3.1 Procedure 1. With the host system or PCI BP powered off connect the IQ80310 into an available PCI slot. 2. Connect the supplied serial cable to a host systems com port 1 and to the serial connector (J-10) on the IQ Boot the host system to Windows NT* 4.0 or Windows 2000*. 4. Run the HyperTerminal connecting using the steps outline in the Intel IQ80310 Evaluation Platform Board Manual, page A2, section A Win32 on Host Connecting with HyperTerminal: To bring up a HyperTerminal session on a Win32 platform: Go to Start, Programs, Accessories, Communications, HyperTerminal > HyperTerminal setup screens Connection Description Panel > Enter name Connect To Panel > Select host com2 port (or whichever port you are using) Port Settings > Bits per second: >DataBits:8 > Parity: none >StopBits:1 > Flow Control: none Start HyperTerminal > Select Call from HyperTerminal panel 5. Power up the IQ80310 with the latest Flash of RedBoot. Application Note 9

10 SettingupIPAddressandPort 6. Applying power to the IQ80310 gives the RedBoot prompt RedBoot> in the HyperTerminal window. Figure 2. Intel IQ80310 Hyperterminal (RedBoot Prompt Screen) 10 Application Note

11 SettingupIPAddressandPort 7. At the RedBoot> prompt type: fconfig l. That returns some configuration information like that shown below: RedBoot> fconfig -l Run script at boot: false Use BOOTP for network configuration: false Local IP address: Default server IP address: GDB connection port: 9000 Network debug at boot time: false Figure 3. Intel IQ80310 Hyperterminal (fconfig -1 Screen) Application Note 11

12 SettingupIPAddressandPort 8. What ever was previously set up on the IQ80310 Local IP address and Default server IP address, is what is seen as this part of the configuration data. When no previous address had been set, these return as zeros ( ). 9. To set the Local IP address and Default server IP address, using the fconfig command at the RedBoot prompt. Type fconfig, this returns each of the line items one-at-a-time and they can be edited, by adding the variable at the end of the displayed line (i.e., Run script at boot: false true). This changes the Run script at boot option to true. When not changing the variable, just hit return to move onto the next variable. Example: RedBoot> fconfig Run script at boot: false Use BOOTP for network configuration: false Local IP address: Default server IP address: GDB connection port: Network debug at host boot time: false This changes the Local IP address and GDB connection port. 10. Set the configuration data to these settings: Run script at boot: false Use BOOTP for network configuration: false Local IP address: <IQ80310 IP_Address> (example ) Default server IP address: GDB connection port: 9000 Network debug at host boot time: false 11. Reset the IQ80310 after changing the configuration to save changes to Flash. 12. It is no longer necessary to maintain the serial cable connection. 12 Application Note

13 Ping Test Procedure 4.0 Ping Test Procedure 1. To ping the host system (the system at the other end of the ethernet cable), do a network connectivity ping test by typing: ping v <host IP address>. Refer to the RedBoot User's Guide at in chapter 2 - RedBoot Commands and Examples. Look under Common Commands and Connectivity, ping - Check network connectivity ping. ping [-v] [-n <count>] [-l <length>] [-t <timeouts>] [-r <rate>][-i <IP_addr>] -h <IP_addr> The ping command checks the connectivity of the local area network by sending special (ICMP) packets to a specific host. These packets should be automatically returned by that host. The command indicates how many of these round-trips were successfully completed. Figure 4. Intel IQ80310 Hyperterminal (Ping Command Screen) Application Note 13

14 Ping Test Procedure Figure To exit the HyperTerminal window, use the mouse to select FILE then EXIT. A dialog pop-up box asks to disconnect the HyperTerminal connection, click Yes 3. This allows pinging in both directions, to and from the host system. From the host system, open a DOS window and type: ping <IQ80310 IP Address>. CMD Window (Ping IP Address Screen) 4. To exit the DOS prompt window type: exit. This completes a successful connection of the two systems via the ethernet connection. 14 Application Note

15 Terminal I/O via Ethernet Running RedBoot Commands Using Telnet, Procedure 5.0 Terminal I/O via Ethernet Running RedBoot Commands Using Telnet, Procedure Figure Set up the IQ80310 as outlined in the Ping test. Insuring that the ping was successfully performed. 2. To open a Telnet session from the host system, open a DOS prompt window and type: telnet at the command line (i.e., C:\WINNT> telnet). 3. At the Microsoft Telnet prompt type: set local echo. Microsoft telnet> set local echo. CMD Window (Telnet Prompt Screen - set local_echo) This Telnet command invokes the full-duplex function of Telnet. Telnet defaults to half-duplex mode where the characters typed within the Telnet window do not appear on the screen, but do get set to the target system. In full-duplex mode the characters typed within the Telnet window do appear on the screen, as well as getting set to the target system. Application Note 15

16 Terminal I/O via Ethernet Running RedBoot Commands Using Telnet, Procedure 4. From the Microsoft Telnet prompt type: open <IQ80310 IP_Address> 9000 Where the <IQ80310 IP_Address> is what has previously been set to be (i.e., Microsoft Telnet> open Figure 7. CMD Window (Telnet Prompt Screen - open ) 5. This connects to the target IQ80310 and give a RedBoot prompt in the DOS window. Figure 8. CMD Window (Telnet Prompt Screen - Boot) 16 Application Note

33 Trouble Shooting 8.0 Trouble Shooting When applying power to the IQ80310 does not produce a RedBoot> prompt in the HyperTerminal window, first check: That the IQ80310 has indeed powered on. The two LEDs on the IQ80310 go from 8.8 to 02 to 66 and stop at 01. This indicates the board has booted and is up and running. When the board does not come up, ensure the power connections to the backplane and or the power supply are correctly connected and to specification. Ensure the serial cable is connected to J-10 on the IQ80310 and to the correct COM port on the host computer. Ensure all HyperTerminal settings are correct per the steps outline in Section 3.0, Setting up IP Address and Port on page 9 and that the newest firmware is used. Use the reset button to toggle the power on the IQ When not sure that the changes were saved to Flash, boot the IQ80310 and check the configuration, using the fconfig l command in a HyperTerminal window. When unable to ping the host computer from the IQ80310, as outline in Section 4.0, Ping Test Procedure on page 13, check that the ethernet cables are correctly connected. When using a crossover cable and it appears to be connected correctly, use a known good cable. When using regular ethernet cables and a hub, use known good cables and hub. Verify the IP addresses are correct and retry the ping test. When the board can be pinged from the host, but not the host from the board, reset the board and retry the ping test, ensuring the correct commands are being used. Application Note 33
