4. Getting started[edit | edit source]

Warning

sysprof is working only with screen resolution at least 700x1200, so it doesn't work on STM32MP135x-DK Discovery kit and STM32MP157x-DKx Discovery kit

Starting sysprof on the board: Need to specify the display to be used, for example:

sysprof --display=/run/user/1000/$WAYLAND_DISPLAY

Sysprof proposes a User interface through the board X interface to the display. It might be more convenient to plug a mouse (and optionally a keyboard) to use the tool interface.

Recording

Clicking on the top left Record button launches the recording. Recording is stopped by clicking on the top left Stop button (that replaces the record button).

The following report is then available on the board display:

5. To go further[edit | edit source]

Several options are available to the user in order to filter the report, and then study the results:

Possibility to browse on Functions list, Descendants list
Possibility to select a certain period of the CPUs graph.
Possibility to save traces, to make screen shots...
