We are trying to run/debug the "FlexRay UNIFIED Driver for MPC5567 Rev A" code on MPC5567EVB board. We are using Codewarrior 2.3 version and for debugging we use the ICDPPCNEXUS debugger (external debugger). The "FlexRay UNIFIED Driver for MPC5567 Rev A" was not building in Codewarrior 2.3 as it was origianally built for Codewarrior 1.5. So to build it on Codewarrior 2.3 we made few changes in "arc.h" and "assert.h" which was documented in "C:\Program Files\Freescale\CodeWarrior for MPC55xxV2.x\Release_Notes\PowerPC_EABI\CW_Tools\Compiler_Notes\CWEmbedded PPC Notes 4.0.x.txt".
Now the problem is when we start the debugger the control comes and struck in assembly function "start" of the "startup.c" and we are not able to stepin from there. Do we need to make any changes in "startup.c" file.
