I guess I should use ddump to look at the .elf to see whether there is a goof up there or in ...

Does anyone know of any better documentation on how to make use of this? Our code has grown to exceed one of the allocated blo...

The problem is in the inner for loop. The first 16 times through the loop all lines execute as expected. After that, when I step through with the debugger, line 12 is executed and the debugger ski...

I am using VxWorks 5.5 with a BSP for the 5307 Coldfire CPU, and the Diab 4.4 compiler. The problem is this: The makeSymTbl.tcl script filters symbols that do not begin with an underscore =93_=94. This removes symbols from the symbol table such as =91dbmul=92 and =91fltused=92 found in libdcc.a., libcfp.a, and/or libimpfp.a. When creating a dynamically loadable module (.out), the load...

We are using the WindRiver ICE for downloading the executable to the board and stepping through. We have our software with the MPC5200B running in default big endian mode. Because the PCI bus is little endian mode we are evaluating the impact on software if we switch th...
