Hi Allison, I was able to resolve the issue thanks to your help. While debugging with the step over function, I found that the code execution was stuck at the following line in F2837xS_SysCtrl.c: while(ClkCfgRegs.SYSPLLSTS.bit.LOCKS != 1) After investigation, I discovered that the oscillator connected to the TMS320F28377S was not properly soldered. Once I re-soldered the component, the code executed as expected and I was able to confirm the EPWM6 signal. Thank you so much for your support. I really appreciate it! Best regards, Seungsoo Kim
