Download U-Boot

Upstream U-Boot

You can clone the u-boot repository by running: 

git clone git://git.denx.de/u-boot.git

Alternatively you can use u-boot-rockchip instead which may with some patches not get in mainline: 

git clone git://git.denx.de/u-boot-rockchip.git

 

Rockchip U-Boot

You can clone the u-boot repository by running: 

git clone https://github.com/rockchip-linux/u-boot.git

  1. EVB RK3328 - use evb-rk3328 configuration
  • RK3399 boards supported:
  1. EVB RK3399 - use evb-rk3399 configuration

 

 

Configure U-Boot

First you need to choose a correct defconfig for your board;

When you have determined what <board_name> you want to build, configure: 

make CROSS_COMPILE=arm-linux-gnueabi- <board_name>_defconfig

You may need to change the U-Boot function/feature support by modify the defconfig file or,

there is also menuconfig to play with settings if you feel like it: 

make CROSS_COMPILE=arm-linux-gnueabi- menuconfig

 

 

Build U-Boot

Get a toolchain

If you haven't done so before, get a suitable toolchain installed and add it to your PATH.

In Ubuntu 14.04, you can use below command to install cross compiler for armv7: 

sudo apt-get install gcc-arm-linux-gnueabi

Or for ARM64 

sudo apt-get install gcc-aarch64-linux-gnu

 

 

Build

For armv7: 

make CROSS_COMPILE=arm-linux-gnueabi-

or for ARM64: 

make ARCH=arm CROSS_COMPILE=aarch64-linux-gnu-

In order to support debug in ARM DS-5, you may need add ctags in make command: 

CFLAGS='-gdwarf-3'

For trust support, we are using FIT image with 'mkimage' cmd in Makefile and its script defined in defconfig: 

make u-boot.itb

Note: please copy the trust binary() to u-boot root directory and rename it to tee.bin(armv7) or bl31.elf(armv8).

The u-boot.itb including u-boot-nodtb.bin, board.dtb, and trust binaries.

Install U-Boot

Rockchip SoCs's bootrom need special format named IDBlock at special offset 0x40 block for boot, so we need to package SPL(or Rockchip miniloader)  in IDB format.

Rockchip bootrom supports SPL back to bootrom and bootrom load the U-Boot, so the SPL for Rockchip SoCs can option to back to bootrom, usually decided by if the IRAM is enough for driver to load U-Boot.

 

 

Using U-Boot SPL

After build complete, U-Boot with SPL support will generate a spl folder with u-boot-spl.bin inside 

tools/mkimage -n rk3288 -T rksd -d spl/u-boot-spl.bin  rk3288_idb.img

This image is supposed to flash to offset 0x40.

For u-boot.bin, it's different for SPL back to bootrom or not, if enable CONFIG_ROCKCHIP_SPL_BACK_TO_BROM, we can append the U-Boot to IDB data: 

cat u-boot.bin >> rk3288_idb.img

If CONFIG_ROCKCHIP_SPL_BACK_TO_BROM not enabled, no more package operation is need for u-boot-dtb.bin, and it need to flalsh to 0x200 which is decide by CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR.

Support ATF with SPL FIT image

 

 

Using Rockchip miniloader

Alternatively, you can use Rockchip miniloader and U-Boot instead which do not need SPL.

The miniloader is package as IDBlock, and the u-boot.bin need to package with rockchip tool: 

loaderimage --pack --uboot u-boot.bin uboot.img

According to the partitions definition, the miniloader should write to offset 0x40 and  this uboot.img should write to offset 0x4000.

 

 

 

Boot up

See boot option about how to boot from eMMC/SD card.

Firmware download in U-Boot

In U-Boot, there are multi way to update image for system, you can chose any of one easy use for you.
