Supported Features
|
|
==================
|
|
|
|
Khadas Edge-V board default configuration supports the following
|
|
hardware features:
|
|
|
|
+-----------+------------+--------------------------------------+
|
|
| Interface | Controller | Driver/Component |
|
|
+===========+============+======================================+
|
|
| GIC-500 | on-chip | GICv3 interrupt controller |
|
|
+-----------+------------+--------------------------------------+
|
|
| ARM TIMER | on-chip | System Clock |
|
|
+-----------+------------+--------------------------------------+
|
|
| UART | on-chip | Synopsys DesignWare 8250 serial port |
|
|
+-----------+------------+--------------------------------------+
|
|
|
|
Other hardware features have not been enabled yet for this board.
|
|
|
|
The default configuration can be found in (NON-SMP)
|
|
:zephyr_file:`boards/khadas/edgev/khadas_edgev_defconfig`
|
|
|
|
There are multiple serial ports on the board: Zephyr is using
|
|
uart2 as serial console.
|
|
|
|
Programming and Debugging
|
|
*************************
|
|
|
|
Use the following configuration to run basic Zephyr applications and
|
|
kernel tests on Khadas Edge-V board. For example, with the :zephyr:code-sample:`hello_world`:
|
|
|
|
1. Non-SMP mode
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:host-os: unix
|
|
:board: khadas_edgev
|
|
:goals: build
|
|
|
|
This will build an image with the synchronization sample app.
|
|
|
|
Build the zephyr image:
|
|
|
|
.. code-block:: console
|
|
|
|
mkimage -C none -A arm64 -O linux -a 0x10000000 -e 0x10000000 -d build/zephyr/zephyr.bin build/zephyr/zephyr.img
|
|
|
|
Use u-boot to load and kick Zephyr.bin to CPU Core0:
|
|
|
|
.. code-block:: console
|
|
|
|
tftpboot ${pxefile_addr_r} zephyr.img; bootm start ${pxefile_addr_r}; bootm loados; bootm go
|
|
|
|
It will display the following console output:
|
|
|
|
.. code-block:: console
|
|
|
|
*** Booting Zephyr OS build XXXXXXXXXXXX ***
|
|
Hello World! khadas_edgev
|
|
|
|
Flashing
|
|
========
|
|
|
|
Zephyr image can be loaded in DDR memory at address 0x10000000 from SD Card,
|
|
EMMC, QSPI Flash or downloaded from network in uboot.
