Hi, [quote userid="632656" url="~/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1495757/tms320f2800137-setting-gpio-pin-as-output-pulls-down-nsleep-pin-and-shuts-down-ldo-on-drv8317"]The problem is when the nSLEEP GPIO fom F2800137 is configured as output, the CPU looses debug connection. [/quote] Which CPU loses debug connection? Are you talking about f280013x CPU? GPIO config has no connection to CPU state, can you check the MCU separately (standalone) without connecting DRV, Zener or pull up. and toggle gpio Thanks
