I tried to add the FreeMaster component to my MCF51JM128 project in CW for MCU v10.4. I had a problem because the component showed red X and did not allow a dependent component to be selected (Init_SCI or Init_MSCAN).
I found that the files "C:\Program Files\Freescale\CW MCU v10.4\MCU\ProcessorExpert\Beans\FreeMaster\Init_SCI.int" and "C:\Program Files\Freescale\CW MCU v10.4\MCU\ProcessorExpert\Beans\FreeMaster\Init_MSCAN.int" have an error in them.
"\Init_SCI.int" Line 47 reads: <Template>Init_SCI_CFV1</Template> should be edited to <Template>Init_SCI_COLDFIREV1</Template>
"Init_MSCAN.int" Line 45 reads: <Template>Init_MSCAN_CFV1</Template> should be edited to <Template>Init_MSCAN_COLDFIREV1</Template>
I needed administrator privileges to edit the files. After that I could get my project to run.
Previously I used CodeWarrior 'Classic' with FreeMaster support (other MCUs) outside of Processor Expert. Now I have FreeMaster for MCF51JM128 in CW for MCU v10.4 with Processor Expert!
I learned a lot of useful info from here as well: Tutorial: FreeMASTER Visualization and Run-Time Debugging | MCU on Eclipse
