RK3399

8.1.7. RK3399#

This BSP family supports the following variants:

  • rk3399_rockpro64

This BSP should also support other boards using the RK3399 SoC. Not all supported boards have a dedicated image generated, in most cases it is sufficient to replace u-boot with the correct one.

The BSP is known to run on these boards:

  • PINE64 RockPro64

  • FriendlyELEC ROM-RK3399

    …

The basic hardware initialization is performed by the BSP. The BSP support the GICv3 interrupt controller present in the RK3399 SoC. The device tree is not supported.

8.1.7.1. Booting a RTEMS image on the PINE64 RockPro64 board#

Disable eMMC#

Please refer to the RockPro64 documentation to select the SD card as the boot device.

Boot via U-Boot#

This BSP supports mainline U-Boot. The U-boot version used when testing this BSP was the master branch 141be72e2a9d43aa4e3d1a6a6e0ab8f9eb8784c6.

Booting via Network#

The BSP can be booted via a TFTP server. To do that using an U-Boot console, use the following commands:

setenv ipaddr 192.168.1.2;
setenv serverip 192.168.1.1;
tftpboot ${pxefile_addr_r} rtems-app.exe;
bootelf -s ${pxefile_addr_r};
go 0x00200000;

This is the entire boot sequence:
