Hello,
It got connected by following your instructions. But MCAT tool is showing this error. please reply me soon as I have spent lot of time on this. if I don't get any output from this. I may be lost of all my time which I spent on this development.
Check the following variables in FreeMASTER:
Board ID = hvp-kv46f
Motor Type = pmsm
sAppIdFM.cAppVer = 1.1.1
MCAT recognizes the type of application from these variables. If these variables are incorrect, double check the Symbol file (posted above, 1.6.2016 4:49).
BR,
Josef
I changed the device setting to KV46F150M. program compiled without errors. Then downloaded the program. but when I open MCAT file, it is showing no symbol found. Version of IAR is 7.40.3.8938.
Double check build configurations. If you build/download the debug configuration in IAR, you must select the "debug" path for symbol file in FreeMASTER. The same applies for the release configuration:
If I didn't answer your question or it doesn't help, make a screenshot of the error, please.
BR,
Josef
Check Project -> Options if a correct device is selected (MKV46F256xxx16):
And write me which version of IAR you are using. The IAR Project Options are sometimes confused among different versions.

Still the same problem with the symbol file and nonsense variables? There are 2 configurations (Debug = no optimization, Release = optimized for speed). If you compile/download debug configuration, there must be the debug in the symbol file path at FreeMASTER. The same applies for the Release configuration:
Let me know your comments,
Josef
U r absolutely right. Every time I open the MCAT tool, It gives me a pop-up saying that no symbol found. I click on continue to further use of MCAT tool.
I am tuning PMSM motor using HVP-KV46F150M board which has not got the dedicated MCAT file on NXP website. I only can see freemaster file. But I am using MCAT tool file which is given for HVP-KV46F256M. May be this is actually giving me a problem. Please attach the MCAT TOOL file for HVP-KV46F150M board. It would be a great help for me.
Otherwise, tell me where do I get those symbol file ??, Reply soon

If you have just started and have not written a lot of your own code to the original application, the best would be to download the newest MCRSP-PMSM (Motor Control Reference Solution Package for PMSM) here:
3-Phase PMSM Motor Control Reference Design|NXP
You can find there the project files, FreeMASTER file and MCAT for all supported platforms (KV46 too). At first try it as it is (just check Release/Debug configurations, see Release notes chapter 8.1).
If you don't want to try the MCRSP-PMSM and keep working with your application you can try to copy the FreeMASTER + MCAT from the package manually, but it won't work correctly because of development.
Where did you get the code you have? Is it the HVP-KV46 Quick Start Package? My advice is to download the MCRSP-PMSM package. The Quick Start Package is not maintained and no bugs are fixed there:

Hello,
I am tuning PMSM motor as per application note 4912 for FOC algorithm. To tune the motor, we will start by entering the motor parameters into the MCAT tool. once i generate the appconfig file from it. Application note says choose the V/F control. Every time i pressed the application switch, (scalar control is enabling, but application is not going to RUN state even i click on application switch) It always go to the fault mode while tuning in V/f mode to get the pure sinusoidal currents as motor currents. Please reply as i am half way through this procedure to get exact results.
Hi sandeep,
From the screenshots you shared, I can see that FreeMASTER is reading nonsense (see the Variable Watch window, e.g. unknown, ?, etc.). Most probably, the symbol file that your FreeMASTER is using doesn't correspond to code in your target. The symbol file says where the variables are placed in target memory so if it is incorrect or outdated, then FreeMASTER reads/writes wrong addresses. Symbol file selection (for IAR it is *.out):
Also when you rebuild your application, the symbol file is re-generated. FreeMASTER recognizes it and asks if you want to reload it. Always click yes:
If you get "Missing Symbol Definitions" pop-up, it means that the symbol file is missing or the listed variables (that FreeMASTER is trying to read) has no record in the symbol file:
Because MCAT interacts with FreeMASTER watched variables it is crucial to have the above fixed.
BR,
Josef
Hi
You can see the parameters tab screenshot above. What else parameters I can send?
The maxon motor, which I try to drive;
I'm not selecting any parameter form current tab. Each time I pressed, it gives error and calculates again. But I think it can not write/store these values.
