CodeWarrior 10 to CrossWorks project conversion

Hello,

what is the easiest way to convert CodeWarrior 10 project (we would like to use Freescale USB stack Kinetis sample projects) to CrossWorks? If it is not straightforward procedure, is it, at least, possible to debug Codewarrior AFX files in Crossworks?

We are able to build Codewarrior project, copy Codewarrior's AFX file to Crossworks empty project, rename it to <crossworks_project_name>.elf, launch debugging in Crossworks (it will load Codewarrior's AFX file - now elf file), but disassembly looks  weird, e.g.:

 SIM_SCGC5 |= SIM_SCGC5_PORTB_MASK | SIM_SCGC5_PORTC_MASK; /* Enable clock gating to port B & C */
    0138F248    teqeq r8, r8, asr #4
    0104F2C4    smlabteq r4, r4, r2, pc
    F4406808    vst2.8 { d22, d23 }, [r0], r8
    60086040    andvs r6, r8, r0, asr #0
--- Boot_loader_task.c -- 114 ------------------------------ /* Enable LEDs Port B pin 0 & 1 */
PORTB_PCR0 |= PORT_PCR_SRE_MASK /* Slow slew rate */
    0100F24A    undefined opcode
    0104F2C4    smlabteq r4, r4, r2, pc
    F0406808    undefined opcode
    60080064    andvs r0, r8, r4, rrx

The program executes but we are nut sure if it does what it should do.
