I am using STM32F4xx and WICED SDK 3.0.0.
I found that the "Step Into/Step Over" options from the "Run" menu in WICED SDK IDE sometimes became unavailable while I was debugging a program. I'm wondering if there is anything I can do to make these options available by, for example, modifying the Makefile?
It works for me as expected.
Put a break point where your application application_start() then start debugging. Hit the F8 (resume) to run and it should stop at your break point. Then you can step through your application.
Please check out Creating and/or Editing Debug Configurations for settings.
