Hi,
When i connect the HVP-Kv31f120M with KMS I'm getting an error message which is the same as discussed in forum " Problem connecting KMS to FRDM-KV31F". All the solutions as discussed have been tried but still I'm unable to connect it. I'm using a 32 bit operating system. Is that could be a problem?
Kindly provide solution for this
Thanks and Regards

Solved! Go to Solution.
Sir,
I checked whether KMS image is erased using debugging mode in IAR. It stopped at hard Fault interrupt. But when we checked the daughter card the MCU is not with KMS enabled. (MKV31F512VLL12). There is no P specified in the MCU. We had MCUs with KMS enabled. so de-solder it and replaced with the new one. Now it is working. Thank you so much.
This is the daughter card which we have ordered from digikey.
Thanks and Regards,

Hello,
The KMS image might be erased. If the KMS execute only image is not there the KMS project will not execute.
To be sure of the cause of the issue please open the project in the IAR IDE, compile the release version of the project, download and debug the project.
After you hit the go, wait a couple of seconds, pause and look at where the project stops.
If it stops at a hard fault interrupt then the KMS library image is not present.
The image might not be there because
1) it was not there in the first place, you received a KV31 HVP daughter card that did not have KMS on it ever.
or
2) In your previous attempts to connect, you mass erased the MCU, which will destroy the KMS library image as well.
If the image is not there, the only solutions I can offer is to remove the MCU (de-solder) and replace it with another MCU that is KMS enabled. The other option is to purchase a new KMS known good HVP-KV31 board.
KMS supports either PMSM motors or ACIM motors. The HVP-KV31 was pre-programmed with the PMSM KMS library image. If you want to check out ACIM on KV31 you will need to send the HVP-KV31F board to me and I can re-program it with the ACIM KMS library image.
If the KMS library is gone, you can still use the card with the NXP reference projects which uses Freemaster. See this page to download the software package. or select here. Software for 3-Phase Permanent Magnet Synchronous Motor (PMSM) Motor Control(REV 1.2.0)

Perfect, I'm happy that you were able to get it working.
The stock at Digikey pre-dates the release of KMS in May of 2016. That is why the KMS library code was not there.
Happy motoring.

Sir,
I will check whether KMS image is erased. But when i try to connect daughter card with KMS i got the error message. So how it will get erased?. One more thing, before connecting with KMS we have tried to run the motor with the same card using the software package what you have suggested( Software for 3-Phase Permanent Magnet Synchronous Motor (PMSM) Motor Control(REV 1.2.0)) . i was able to build the program using KDS,but when we connect to freemaster some fault occured. We have worked with KV46F150M(without KMS enabled) with same software package.
Thanks and Regards,

In my experience with the PMSM motor control package the freemaster uses the release version of the symbol file. If you re-compile both the debug and release version then in freemaster re-specify the new .elf file it should work.
You should have all the tools to get just about any motor working.
If you want to use KMS with ACIM you will need to purchase a HVP-KV4 board from NXP directly. None of the distributors have stock of the KMS enabled HVP-KV4 boards.
The KMS updated HVP-KV4 with ACIM KMS library is also in all of the HVP -3PH platform kits from NXP directly as well.
Best Regards,
Philip
We will be releasing a new Reference manual and Data sheet as well as new part numbers for the KMS ACIM MCU's for KV3 and KV4. The PMSM have the P suffix and the ACIM parts will have a Q suffix.

Athulya,
When using the HVP-KV31F120M with the HVP-MC3PH are you plugging into the USB Type-B connector on the HVP-MC3PH or on the micro USB connector on the HVP-KV31F120M?
Can you share the text that comes up after clicking "Load Application Image"?
Sir,
I'm getting this notification. And Red led in the controller card started blinking
After you see that notification, click OK. KMS will still open. Next click Project -> Load Application Image. Please copy and paste all of the text that appears in that notification box and paste into the forum.
Sir,
After load application image ,the below notification image arise.
Again if try to connect Im getting the same issue message

Were you able to put the HVP-KV31 card into bootloader mode?
You can do the bootloader code work with the card removed from the HVP-3PH platform.
I hope this helps.

Sir,
Thank you for the reply. I tried with your solution and i could update the SDA version.
I have created KMS project with COM port 6
But when i try to connect again the same notification will come
After that i clicked on Load application image i got the message which is shown below
Again if try to connect same issue is occuring
Sorry for the late reply.
