我有一个由TWR-KV31F120M板、TWR-MC-LV3PH板和45ZWN24-40电机组成的评估系统，可以运行MCRSP-PMSM-V1.1.1参考解决方案。但这个系统与KMS(kinetis motor suite)总也连不上，每次总是提示“Could not verify communication over port COMxx”，不知是什么原因。我的TWR-KV31F板是今年3月才买的，我也在WIN8和WIN10上都试了，结果都一样
The low cost reference platform to get you started with KMS is available to order from nxp.com(here). You will need the following
You may provide your own PMSM motor for the testing. TheLVPMSM shield is typically used for up to 24V 5.1 Amp motors only.
I am assuming this tower board has been enabled for KMS at the factory. If not you will need to order a new TWR-KV31F512 board for use with Kinetis Motor Suite. The debugger must be "MSD-DEBUG-TWR-KV31F12_Pemicro_v118.SDA" or later.
If it is a KMS enabled TWR board and the debugger version is correct, then please try starting from a new KMS project, once KMS tries to open the serial port it might ask you to load the new project onto the MCU. If it does not use the project --> load .out file function to load the KMS project onto the TWR board. After this has completed and if there is voltage supplied to the LV3PH then the yellow LED will flash slowly on the TWR board. If there is a RED LED you may have a fault condition due to jumper issues. consult the KMS users guide for jumper placement.
Once the yellow light is flashing try communicating with the TWR board.
