|
*************************
|
|
|
|
|
|
|
|
|
|
Use this configuration to run basic Zephyr applications and kernel tests in the QEMU
|
|
|
|
|
emulated environment, for example, with the :ref:`synchronization_sample`:

:goals: run

|
|
|

|
This will build an image with the synchronization sample app, boot it using
|
|
|
|
|
QEMU, and display the following console output:
