SWO is supported on the STM32H743I-EVAL.


In order to make SWO working correctly, min. J-Link software V6.33a is required. Previous versions are not guaranteed to work correctly with SWO.

Sample projects

The following sample projects that demonstrate SWO on the STM32H743I-EVAL are available:

This example project does not require any extra settings by the user. The SWO stream can be viewed with e.g. JLinkSWOViewer which is included in the J-Link software and documentation package and is available for free.

  • IAR EWARM 8.22 sample project
  • Note: IAR does not handle the special setup needed for this particular target device automatically so the project setting "CPU clock" must be set to 20 MHz when using 64 MHz default CPU clock. Any other value will not output the SWO printf stream.
