ARM DS-5 Using the Debug Hardware Configuration Utilities

Creating debug hardware target configurations5.28 Adding autoconfigure support for new platformsWhen adding platforms to the Select Platform dialog box, a platform detection file .det iscreated automatically after you have setup the board name and manufacturer. You can, however,add more .det files to the platformFiles directory, which allow different hardware versions tobe recognized when you click the Auto Configure button. A .det file can contain informationfor one or more platforms. The platform description consists of a JTAG ID code and mask foreach device on the JTAG scan chain of the target platform, and the name of the associated debughardware configuration file .rvc.For example:0x0B73B02F,0xFFFFFFFF, 0x07926001,0xFFFFFFFF, 0,0, 0x2B900F0F,0xFFFFFFFF =mycompany_eg1.rvcIn the above example, the platform is expected to contain four devices on its scan chain. Thefirst device must have a JTAG ID code of 0x0B73B02F, the second 0x07926001, the third devicecan have any ID code, and the code of the fourth device must be 0x2B900F0F.Several .det files can be supplied, and each file can contain more than one line. For example:0x22193024, 0xEFFFFFFF, 0,0, 0,0 = mycompany_eg2.rvc0x08210024, 0xFFFFFFFF, 0,0, 0,0 = mycompany_eg2.rvc0x05310024, 0xFFFFFFFF, 0,0, 0,0 = mycompany_eg3.rvcIn this example, a scan chain containing three devices, where the first device has an ID code of0x22193024, 0x32193024 or 0x08210024 is associated with mycompany_eg2.rvc. The mask value of0xEFFFFFFF means that both 0x22193024 and 0x32193024 are identified. If there are three devices,and the first has an ID code of 0x05310024, then it is associated with mycompany_eg3.rvc.When you click the Auto Configure button, the detected scan chain is compared against all theplatforms described by .det files. If the connected target matches any of these platforms, aSelect Platform dialog box is displayed, and asks the user to confirm that the platform has beencorrectly detected.It is possible to create platform information that associates a given scan chain with several .rvcfiles. If this happens, the Select Platform dialog box lists all the platforms that match, and youwill be asked to select the platform that matches your hardware.5.28.1 See alsoTasks• Adding new platforms on page 5-45.ARM DUI 0498F Copyright © 2010-2012 ARM.
