If the active application has several build contexts, you can set which of them is active. You can select the active build context by clicking on it.
Tip
You can also use the Set Active Context command in the Command Palette or in the extension status item in the Status Bar.
Setting the active context can have impact on several areas of the extension. The active context determines the content of the Details View because each context might use different files. As a result, Actions View can also show different actions for the selected context (for example, if the active build context does not have an ELF file, the extension does not show the Debug action for this context). The active context can also be configured to use a board target that is not compatible with connected devices.
