Create a new configuration database
|
|
***********************************
|
|
|

|
Create a new model configuration
|
|
********************************
|
|
|
|
Right click ``Zephyr`` in ``Project Explorer``, choose ``New -> Model Configuration``:
|
|
|
|
.. image:: images/create-new-model-configuration.jpg
|
|
:align: center
|
|
:alt: Arm DS create new model configuration
|
|
|
|
In the opened window:
|
|
|
|
1. Choose ``Iris`` for ``Model Interface``, then ``Next >``.
|
|
2. Choose ``Launch and connect to specific model``, then ``Next >``.
|
|
3. Set ``Model Path`` to ``$FVP_D/FVP_BaseR_AEMv8R``, then ``Finish``.

|
|
:align: center
|
|
:alt: Arm DS create new model configuration: set model path
|
|
|
|
Then in ``FVP_BaseR_AEMv8R`` tab, change ``ARMAEMv8-R_`` to ``V8R64-Generic``,
|
|
click ``Save`` and then click ``Import``:

|
|
Create a new launch configuration
|
|
*********************************
|
|
|
|
From ``Project Explorer``, right click ``FVP_BaseR_AEMv8R`` and select ``Debug as -> Debug configurations...``:
|
|
|
|
.. image:: images/create-new-launch-configuration_context-menu.jpg
|
|
:align: center
|
|
:alt: Arm DS create new launch configuration: context menu
|
|
|
|
Select ``Generic Arm C/C++ Application`` and click ``New launch configuration`` button.
|
|
A new configuration named ``New_configuration`` will be created.
|
|
|
|
1. In ``Connection`` tab:
|
|
|
|
- In ``Select target`` box, select ``Imported -> FVP_BaseR_AEMv8R -> Bare Metal Debug -> ARMAEMv8-R_MP_0``
|
|
- In ``Connections`` box, set ``Model parameters`` to::
|
|
|
|
-C bp.dram.enable_atomic_ops=1 -C bp.sram.enable_atomic_ops=1 -C bp.refcounter.non_arch_start_at_default=1 -C gic_distributor.GICD_CTLR-DS-1-means-secure-only=1 -C gic_distributor.has-two-security-states=0 -C bp.vis.disable_visualisation=1 -C cluster0.has_aarch64=1 -a /home/fengqi/zephyrproject/build/zephyr/zephyr.elf
|
|
|
|
These parameters are passed to ``FVP_BaseR_AEMv8R`` when launches. Run ``FVP_BaseR_AEMv8R --help``
|
|
to see all command line options. Run ``FVP_BaseR_AEMv8R --list-params`` to see all supported parameters.
|
|
The file ``zephyr.elf`` specified by ``-a`` is the binary built from Zephyr.

|
|
2. In ``Files`` tab:
|
|
|
|
In ``Files`` box, set ``Load symbols from file`` to full path of ``zephyr.elf`` that you built.

|
|
|
3. In ``Debugger`` tab:
|
|
|
|
- In ``Run control`` box, check ``Execute debugger commands`` and insert::
|
|
|
|
add-symbol-file "/home/fengqi/zephyrproject/build/zephyr/zephyr.elf" EL1S:0
|
|
|
|
Replace ``/home/fengqi/zephyrproject/build/zephyr/zephyr.elf`` with your local path.
|
|
|
|
- In ``Paths`` box, set ``Source search directory`` to the path to Zephyr source code.

|
|
|
|
After all these changes are made, click ``Apply``, then click ``Debug``. DS will
|
|
launch ``FVP_BaseR_AEMv8R`` and connect to it. You can see a new session is
|
|
connected in ``Debug Control`` window.
