TMS320F28377S: UNUSED EPWM PINS

eeddii iiiiii

Hi !

I'm now facing some troubleshoot problem. I have constructed three phase inverter with TMS320F28377S dsp . The problem is the there is not connection with the DSP through JTAG connection . When I try just test connection , the connection is best. I'm using only EPWM1A, EPWM1B, EPWM2A,EPWM2B, and also EPWM3A, EPWM3B . Another unused EPWM pins are connected to ground. Is it true to connect unused EPWM and unused GPIO pins to ground ?

Thanks !

Yeah... that's recommended.

You mean to say that you're unable to debug and program?

What error do you get? Also, is this a custom board? If yes, are you trying to load the code for the first time?

Is it the F28377S launchpad?
