Dear Edward,
in the "MC33771C/772C Evaluation GUI V5.13" please click the Info button and when it opens, please click the Help button. It opens an "EvalGUI Documentation".
Please follow the "Getting Started" instructions. Please confirm, that you have a battery emulator or a battery pack for each of the MC3377xC BCC used. I understand, that you are using the FRDMDUAL33664EVB for the TPL communication.
Please check if the S32K144=>OpenSDA is visible in the Device Manager on your machine. If not please disconnect and reconnect the USB cable and please check again.
After that please follow the instructions in the "Initial Configuration" section. Please download the SREC drive software for the S32K144.
Please select Port as it is visible in the Device Manager. In my case it's COM9. In your case might be and probably will be different.
After that please click Connect.
You also need to have connected a battery pack or a battery emulator with a voltage supply for each of the BCCs you are using. If you will follow the instructions above, the the S32K144 controller will be connected and the PackCtrl field in the GUI will be green, but the BMS will never be initialized and the BMS field will switch between orange color, trying to initialize the BCC, and red color, indicating error.
With Best Regards,
Jozef
