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:
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.
