Other Parts Discussed in Thread: TMDSDOCK28379D, TMDSCNCD28379D
I recently purchased a TMS320F28379D Control Card and Docking Station (TMDSDOCK28379D kit). I plugged the Control Card into the Docking Station, and connected the supplied USB cable to the Control Card. Initially, I did NOT connect a USB cable to the Docking Station because I thought the Control Card was capable of operating in standalone mode. In this configuration, Code Composer Studio (CCS) Debugger was not able to communicate with the Control Card. As you can see in the first picture below, that only the green LED 'A-D2' on the Control Card is ON. The LEDs LD1, LD2, LD3 are OFF (indicating that the processor-portion of the Control Card is not powered up. I thought that having USB connected to Control Card would power the entire board, but apparently not. (see more text after photo)
So then I added a USB cable to the Docking Station. Now all the LEDs are ON (see photo #2 below) and I was able to use CCS to successfully load and run programs. (more text after photo)
Why do I need to provide USB Cable to the Docking Station if I have USB Cable to the Control Card? Shouldn't just one USB Cable to the Control Card be sufficient to load and run a program?
Please help me understand. Thanks.
