When I debug the usb of stm32f103, using ST firmware library and st-link .Will appear the following questions:
I want to suspend operation, but the IAR will be prompted to me that "Target is running,Failed to stop the target"!!
If I delete the code:
NVIC_InitStructure.NVIC_IRQChannel = USB_LP_CAN1_RX0_IRQn;
  NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 6;
  NVIC_InitStructure.NVIC_IRQChannelSubPriority = 7;
  NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
  NVIC_InitStructure.NVIC_IRQChannel = USBWakeUp_IRQn;
  NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 5;
  NVIC_InitStructure.NVIC_IRQCha */
There is no problem for debug
Why ???   (My English ability is very poor, but I tried my best to in the description)aa18972bd40735fa0e8b8c2b9d510fb30f24082d.jpg
