how to use systemview #9991

Closed laoniaokkk closed 1 year ago

laoniaokkk commented 1 year ago

I tried to use sysytemview to reference the sim/segger configuration, but I didn't succeed, and the issue on systemview was also unsuccessful. I would like to know how to go about setting it up to use correctly.

@xiaoxiang781216 I think we need a concise Documentation like we have to Debug Trace

I checked this issue but my issue is not solved, my NUTTX system version is 12.0.0 and my chip is stm32f429. I made sure the program executed up_perf_init() and opened DWT inside. When I click "Start Recording", SystemView doesn't show anything, then click "Stop Recording" to display as below. Can you give me your profile?

SystemView

@Gary-Hobson could you share some defconfig?

@laoniaokkk you can try this PR https://github.com/apache/nuttx/pull/10006 There is an example systemview configuration for nucleo-f446re. The main problem I encountered with enabling systemview is CONFIG_DRIVERS_NOTERAM=y which is the default option and at the same time CONFIG_DRIVERS_NOTE_MAX=1. This causes systemview support to fail and no error is reported to the user.

Yes,I made CONFIG_DRIVERS_NOTE_MAX=2, and then the SystemView was work well
