Q:

I have loaded in one of the example arm projects for the EFM32 Starter Kit with Keil µVision. When I enter debug mode, it only shows the disassembly window and I am not able to debug the C-code. What is wrong?

A:

Go to the project settings within Keil µVision and ensure that the "Debug Information" box is checked under the "Output" tab, like shown below. Once you have recompiled with these settings, you should be able to do C debugging.
