SWO

On the STM32H7 series devices from ST SWO is supported. However, a few device specifics apply which are described in the following section.

SWO register access

For most Cortex-M devices, the SWO registers are accessible by the AHB-AP. This is not the case for the STM32H7 series devices. In this case the registers need to be partially accessed by the APB-AP.

Note: J-Link handles the current setting of this registers automatically. J-Link software version V6.32a or later is required.


Note: The settings are applied by a compiled .JLinkScriptfile located in the J-Link software installation folder under /Devices, should you need the original source it can be requested at support@segger.com
