I can't connect the FRDM-KV31F board with KMS.
At first, not CDC apears when I connect the board to PC. Next I install the "MBEDWinSerial" and now I have a CDC port (In my case COM3).
Now I open KMS and I select the COM port, but its impossible connect with KMS.
Finding a solution I read in other post maybe is a problem with the FRMD-KV31F boards (KMS won't connect to kv31f board.).
How can I solve this problem ??
Thank's a lot.
Unfortunately there was an error in processing over 200 FRDM-KV31 resulting in the MBED OpenSDA being put on the board instead of the P&E bootloader and OpenSDA.
Have you read the document I wrote? https://community.nxp.com/docs/DOC-332745
If this workaround does not work for you I can fix your board. I ask that you send it to me for repair. Let me know how you would like to handle this.

I already saw the post that you comment, but I don't work for me.
I download the Segger_OpenSDA2.1.bin and put it in bootloader mode.
Now the CDC apears as "JLink CDC UART Port (COM6)" in System.
I open a KMS sample "sensorless" project in KDS and I can able to debug using JLink debugger.
The FRDM board, now, show the red LED, and blue blinking LED.
If I connect the LVPMSM board to FRDM-KV31, the FRDM board show green LED and blue blinking.
But I still can't connect with KMS.
Alway get this error from KMS:
Loading a File from C:\Users\paloky\Documents\KMS_1.0.1\SavedProjects\FRDMKV31F_SNLESSVEL_KDS_1_0_1_211(1)\tools\..\KDS\Release\frdmkv31f_SNLESSVEL_KDS.elf
Target Board FRDM-KV31F not found. Cannot download.
I using Windows 10, KDS 3.2 and KMS 188.8.131.52.
If I send you the board, you can fix.
Can you send me the post address to send you the board (I'm from Spain)?
Thank's a lot.
Finally, I have been able to solve the problem.
I read that there could be problems with KDS 3.2. Well, I have installed version 3.0.0 of the KDS.
With KMS 1.01, it was imposile to compile with KDS 3.0. I always got error on the Linker.
I uninstalled KMS 1.01 and installed KMS 1.0.0, and now I have been able to compile with KDS 3.0.
Once the FRDM-KV31 has been programmed with KDS 3.0, I was able to connect to the KMS 1.0.0.
There seems to be some problem with version 1.0.1 of KMS.
Make sure you update the P&E eclipse plug-in if you ever want to use it.
KMS 1.0.1 is only compatible with KDS 3.2 and will not work with KDS 3.0
KMS 1.0.0 is only compatible with KDS 3.0.1 with updates and does not work with KDS 3.2.
All of this is in the release notes and the getting started videos.
Glad you were able to use it after all.
