Programming and Debugging
*******************************
.. zephyr:board-supported-runners::
There are multiple methods to program and debug Zephyr
Option 1. Boot Zephyr by Using JLink Runner
===========================================
The default runner for the board is JLink, connect the EVK board's JTAG connector to
the host computer using a J-Link debugger, power up the board and stop the board at
U-Boot command line.
Then use "west flash" or "west debug" command to load the zephyr.bin
image from the host computer and start the Zephyr application on A55 core0.
Flash and Run
-------------
Here is an example for the :zephyr:code-sample:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:host-os: unix
:board: imx91_evk/mimx9131
:goals: flash
Then the following log could be found on UART1 console:
.. code-block:: console
*** Booting Zephyr OS build v4.1.0-3063-g2c7ef313ac38 ***
Hello World! imx91_evk/mimx9131
Debug
-----
Here is an example for the :zephyr:code-sample:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:host-os: unix
:board: imx91_evk/mimx9131
:goals: debug
Option 2. Boot Zephyr by Using U-Boot Command
=============================================
U-Boot "go" command is used to load and kick Zephyr to Cortex-A55 Core.
Copy the compiled ``zephyr.bin`` to the first FAT partition of the SD card and
