Building

TF-A

TF-A is required when building ARM64 Rockchip SoCs images.

To build TF-A:

git clone --depth 1 https://github.com/ARM-software/arm-trusted-firmware.git
cd arm-trusted-firmware
make realclean
make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399
cd ..

Specify the PLAT= with desired Rockchip platform to build TF-A for.

For SoCs whose TF-A code is not available as open source, use BL31 binary provided by Rockchip:

git clone --depth 1 https://github.com/rockchip-linux/rkbin

TPL

For some SoCs U-Boot sources lack of support to inizialize DRAM. In these cases, to get a fully functional image following 1. Package the image with U-Boot TPL/SPL, use DDR binary provided by Rockchip rkbin repository as ROCKCHIP_TPL when building U-Boot. Otherwise, follow 2. Package the image with Rockchip miniloader.

U-Boot

git clone --depth 1 https://source.denx.de/u-boot/u-boot.git
cd u-boot

make evb-rk3588_defconfig
make CROSS_COMPILE=aarch64-linux-gnu-

Flashing

1. Package the image with U-Boot TPL/SPL

SD Card

All Rockchip platforms (except rk3128 which doesn’t use SPL) are now supporting a single boot image using binman.

To write an image that boots from a SD card (assumed to be /dev/sda):

sudo dd if=u-boot-rockchip.bin of=/dev/sda seek=64
sync

eMMC

eMMC flash would probe on mmc0 in most of the Rockchip platforms.

Create GPT partition layout as defined in $partitions:

mmc dev 0
gpt write mmc 0 $partitions

Connect the USB-OTG cable between the host and a target device.

Launch fastboot on the target with:

fastboot 0

Upon a successful gadget connection the host shows the USB device with:

lsusb
# Bus 001 Device 020: ID 2207:330c Fuzhou Rockchip Electronics Company RK3399 in Mask ROM mode

Program the flash with:

sudo fastboot -i 0x2207 flash loader1 idbloader.img
sudo fastboot -i 0x2207 flash loader2 u-boot.itb

Note:

For Rockchip 32-bit platforms the U-Boot proper image is u-boot-dtb.img

SPI

Write u-boot-rockchip-spi.bin to offset 0 of SPI flash.

Copy u-boot-rockchip-spi.bin into SD card and boot from SD:

sf probe
load mmc 1:1 $kernel_addr_r u-boot-rockchip-spi.bin
sf update $fileaddr 0 $filesize

2. Package the image with Rockchip miniloader

Image package with Rockchip miniloader requires rkbin [1].

cd ..
git clone --depth 1 https://github.com/rockchip-linux/rkbin

Create idbloader.img:

cd u-boot
./tools/mkimage -n px30 -T rksd -d ../rkbin/bin/rk33/px30_ddr_333MHz_v1.16.bin idbloader.img
cat ../rkbin/bin/rk33/px30_miniloader_v1.31.bin >> idbloader.img
sudo dd if=idbloader.img of=/dev/sda seek=64

Create trust.img:

cd ../rkbin
./tools/trust_merger RKTRUST/PX30TRUST.ini
sudo dd if=trust.img of=/dev/sda seek=24576

Create uboot.img [2]:

cd ../u-boot
../rkbin/tools/loaderimage --pack --uboot u-boot-dtb.bin uboot.img 0x200000
sudo dd if=uboot.img of=/dev/sda seek=16384

Note:

  1. rkbin binaries are regularly updated, so it would be recommended to use the latest version.

  2. 0x200000 is a load address and is an option for some platforms.

3. Package the RK3066 image with U-Boot TPL/SPL on NAND

Unlike later SoC models the rk3066 BootROM doesn’t have SDMMC support. If all other boot options fail then it enters into a BootROM mode on the USB OTG port. This method loads TPL/SPL on NAND with U-Boot and kernel on SD card.

SD Card

U-Boot expects a GPT partition map and a boot directory structure with files on the SD card.

Partition Map for MMC device 0  --   Partition Type: EFI
Part     Start LBA         End LBA           Name
1        0x00000040        0x00001f7f        "loader1"
2        0x00004000        0x00005fff        "loader2"
3        0x00006000        0x00007fff        "trust"
4        0x00008000        0x0003ffff        "boot"
5        0x00040000        0x00ed7fde        "rootfs"

Make sure boot and esp flag are set for the boot partition. Loader1 partition is not used by RK3066.

Boot partition:

extlinux
  extlinux.conf

zImage
rk3066a-mk808.dtb

To write a U-Boot image to the SD card (assumed to be /dev/sda):

sudo dd if=u-boot-dtb.img of=/dev/sda seek=16384
sync

NAND

Bring device in BootROM mode:

If bricked and no BootROM mode shows up then connect pin 8 and 9 of the NAND flash with a needle while reconnecting to the USB OTG port to a PC.

Show connected devices with:

lsusb
# Bus 001 Device 004: ID 2207:300a Fuzhou Rockchip Electronics Company RK3066 in Mask ROM mode

Create NAND image:

Size of SPL and TPL must be aligned to 2kb.

Program with commands in a bash script ./flash.sh:

#!/bin/sh

printf "RK30" | dd conv=notrunc bs=4 count=1 of=u-boot-tpl.bin
truncate -s %2048 u-boot-tpl.bin
truncate -s %2048 u-boot-spl.bin
../tools/boot_merger --verbose config-flash.ini
../tools/upgrade_tool ul ./RK30xxLoader_uboot.bin
