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) 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 Hello World:

  1. Non-SMP mode

# From the root of the zephyr repository
west build -b khadas_edgev samples/hello_world

This will build an image with the synchronization sample app.

Build the zephyr image:

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:

tftpboot ${pxefile_addr_r} zephyr.img; bootm start ${pxefile_addr_r}; bootm loados; bootm go

It will display the following console output:

*** 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.
