This is the Wiki for the Renesas R-Car White Hawk board stack. It consists of:

  • White Hawk CPU board equipped with R-Car V4H SoC (RTP8A779G0ASKB0FC0SA000),
  • White Hawk BreakOut board (RTP8A779G0ASKB0SB0SA000),
  • White-Hawk CSI/DSI sub-board (RTP8A779G0ASKB0SC0SA000),
  • White-Hawk RAVB/Ethernet(1000Base-T1) sub-board (RTP8A779G0ASKB0SE0SA000).

Refer to the R-Car page for information about Renesas' R-Car SoC family.

Serial Console

Use a micro-USB cable to connect to "Debug Serial" (CN10) on the CPU board. Serial settings are 921600 8N1.

Booting Linux

 * Kernel config: defconfig
 * Kernel image: arch/arm64/boot/Image
 * DTB: arch/arm64/boot/dts/renesas/r8a779g0-white-hawk.dtb

U-Boot boot command:

tftpboot 0x48080000 Image
tftpboot 0x48000000 r8a779g0-white-hawk.dtb
booti 0x48080000 - 0x48000000


PSCI System Suspend

Not yet supported.


The system can be suspended ("frozen") using:

echo freeze > /sys/power/state

Alternatively (since v4.10), you can configure the system to use Suspend-to-Idle by default:

echo s2idle > /sys/power/mem_sleep

After that, you can suspend the system using the standard:

echo mem > /sys/power/state

Wake-Up Sources

Suspend-to-Idle supports the following wake-up sources:

  • gpio-keys: Wake-up using push buttons SW47..SW49 on the CPU board
  • ravb (Ethernet): Configure using one of:
ethtool -s eth0 wol g # Enable wake on MagicPacket
ethtool -s eth0 wol d # Disable

Wake-up by sending a MagicPacket from another system using:

wakeonlan <mac-address> | <hostname> | <ip-address> # <hostname> or <ip-address> must be in /etc/ethers
  • sh-sci (Serial): Disabled by default
