Resolved! Did I brick my board? I'm trying to understand low power mode, and ran the code below and now can't connect to st link.
/* USER CODE BEGIN 2 */ HAL_PWR_EnableWakeUpPin (PWR_WAKEUP_PIN1); gotoSleep(); /* USER CODE END 2 *// * @brief void gotoSleep(void) * * @retval None */void gotoSleep(void){ HAL_Delay(1000); HAL_PWR_EnterSTANDBYMode(); SystemClock_Config();}
