Building
--------
TF-A
^^^^
TF-A is required when building ARM64 Rockchip SoCs images.
To build TF-A:
.. code-block:: bash
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.
U-Boot
^^^^^^
.. code-block:: bash
git clone --depth 1 https://source.denx.de/u-boot/u-boot.git
cd u-boot
To build px30 boards:
.. code-block:: bash
export BL31=../arm-trusted-firmware/build/px30/release/bl31/bl31.elf
make evb-px30_defconfig
make CROSS_COMPILE=aarch64-linux-gnu-
To build rk3066 boards:
.. code-block:: bash
make mk808_defconfig
make CROSS_COMPILE=arm-linux-gnueabihf-
To build rk3288 boards:
.. code-block:: bash
make evb-rk3288_defconfig
make CROSS_COMPILE=arm-linux-gnueabihf-
To build rk3328 boards:
.. code-block:: bash
export BL31=../arm-trusted-firmware/build/rk3328/release/bl31/bl31.elf
make evb-rk3328_defconfig
make CROSS_COMPILE=aarch64-linux-gnu-
To build rk3368 boards:
.. code-block:: bash
export BL31=../arm-trusted-firmware/build/rk3368/release/bl31/bl31.elf
make evb-px5_defconfig
make CROSS_COMPILE=aarch64-linux-gnu-
To build rk3399 boards:
.. code-block:: bash
export BL31=../arm-trusted-firmware/build/rk3399/release/bl31/bl31.elf
make evb-rk3399_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 and pad_cat.
To write an image that boots from a SD card (assumed to be /dev/sda):
.. code-block:: bash
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:
.. code-block:: bash
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:
.. code-block:: bash
fastboot 0
Upon a successful gadget connection the host shows the USB device with:
.. code-block:: bash
lsusb
# Bus 001 Device 020: ID 2207:330c Fuzhou Rockchip Electronics Company RK3399 in Mask ROM mode
Program the flash with:
.. code-block:: bash
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
^^^
The SPI boot method requires the generation of idbloader.img with help of the mkimage tool.
SPL-alone SPI boot image:
.. code-block:: bash
./tools/mkimage -n rk3399 -T rkspi -d spl/u-boot-spl.bin idbloader.img
TPL+SPL SPI boot image:
.. code-block:: bash
./tools/mkimage -n rk3399 -T rkspi -d tpl/u-boot-tpl.bin:spl/u-boot-spl.bin idbloader.img
Copy SPI boot images into SD card and boot from SD:
.. code-block:: bash
sf probe
load mmc 1:1 $kernel_addr_r idbloader.img
sf erase 0 +$filesize
sf write $kernel_addr_r 0 ${filesize}
load mmc 1:1 ${kernel_addr_r} u-boot.itb
sf erase 0x60000 +$filesize
sf write $kernel_addr_r 0x60000 ${filesize}
2. Package the image with Rockchip miniloader
---------------------------------------------
Image package with Rockchip miniloader requires rkbin [1].
.. code-block:: bash
cd ..
git clone --depth 1 https://github.com/rockchip-linux/rkbin
Create idbloader.img:
.. code-block:: bash
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:
.. code-block:: bash
cd ../rkbin
./tools/trust_merger RKTRUST/PX30TRUST.ini
sudo dd if=trust.img of=/dev/sda seek=24576
Create uboot.img [2]:
.. code-block:: bash
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.
.. code-block:: none
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:
.. code-block:: none
extlinux
extlinux.conf
zImage
rk3066a-mk808.dtb
To write a U-boot image to the SD card (assumed to be /dev/sda):
.. code-block:: bash
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:
.. code-block:: bash
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:
.. code-block:: bash
#!/bin/sh
printf "RK30" > tplspl.bin
dd if=u-boot-tpl.bin >> tplspl.bin
truncate -s %2048 tplspl.bin
truncate -s %2048 u-boot-spl.bin
../tools/boot_merger --verbose config-flash.ini
../tools/upgrade_tool ul ./RK30xxLoader_uboot.bin
config-flash.ini:
.. code-block:: none
