ARM DS-5 Using the Debug Hardware Configuration Utilities

Configuring network settings for your debug hardware unit3.9 TroubleshootingIf you encounter problems when configuring network settings for your debug hardware unit, seethe following:3.9.1 Why am I unable to see my DSTREAM or RVI unit on the network?Seeing or browsing for DSTREAM or RVI units on the network relies on the local area network(LAN) allowing propagation of broadcast packets (UDP) on ports 30000 and 30001. It iscommon to limit the propagation of these types of packets to a localized network region toprevent congestion, but it might be possible to allow propagation of packets on these specificports. Contact your network administrator to request this modification.NoteThis issue is seen when a DSTREAM or RVI unit is behind any network component that filtersnetwork traffic, such as a firewall.3.9.2 When is it appropriate to assign a fixed IP address to my DSTREAM or RVI unit?If it is not possible to browse for the DSTREAM or RVI unit on the network using the tools, youcan attempt to locate the unit by specifying the host name of the unit, for exampleMyDSTREAM.local.example.com.If the host name cannot be resolved, you can use an IP address, for example 192.168.1.16. Inthis case, you might want to assign a fixed IP address to the DSTREAM or RVI unit to preventthis IP address from changing. To request a fixed IP address, contact your networkadministrator. When the address is assigned to the DSTREAM or RVI unit, you can confirm itscorrect operation by using the ping command from a DOS or UNIX prompt prior to connectingthe tools.A fixed IP address is also appropriate when an Ethernet cross-over cable is used. In this case, aprivate network between the host PC and the unit is created, although this might not benecessary due to the availability of a USB connection.3.9.3 Why does my debug connection fail when I connect the Mictor cable to my target?Some target systems have their debug signals connected to both a Mictor trace connector and aseparate debug-only connector. In this scenario, if you connect the Mictor cable alongsideanother debug cable, there is effectively a large unterminated stub on the debug signals. Thiscan cause the debug interface to become unstable. To solve this problem, configure theDSTREAM or RVI software to use the Mictor cable for both the debug and trace signals, anddisconnect any other debug cables.3.9.4 See alsoTasks• Configuring the network settings for a debug hardware unit on page 3-8• Modifying the network settings for a debug hardware unit on page 3-10.Concepts• The Configure Debug Hardware unit dialog box on page 3-4• Debug hardware unit network settings on page 3-7.ARM DUI 0498F Copyright © 2010-2012 ARM.
