STMicroelectronics STM32F3xx Devices

STMicroelectronics STM32F3xx devices support all CoreSight features including ETM, ITM, and DWT trace data. No additional target resources are needed for debugging. By default, these devices debug in JTAG mode, and can be switched to Serial Wire Debug mode.

To use CoreSight trace functionalities, the device, the debugger adapter and connector, as well as µVision have to be configured:


  • When debugging in low-power modes, configure the DBG_SLEEP or DBG_STOP bit of the DBGMCU_CR register first. Otherwise, the debug connection is lost.
