Building
--------
TF-A
^^^^
TF-A would require to build for ARM64 Rockchip SoCs platforms.
To build TF-A::
git clone https://github.com/ARM-software/arm-trusted-firmware.git
cd arm-trusted-firmware
make realclean
make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399
Specify the PLAT= with desired Rockchip platform to build TF-A for.
U-Boot
^^^^^^
To build rk3328 boards::
export BL31=/path/to/arm-trusted-firmware/to/bl31.elf
make evb-rk3328_defconfig
make
To build rk3288 boards::
make evb-rk3288_defconfig
make
To build rk3368 boards::
export BL31=/path/to/arm-trusted-firmware/to/bl31.elf
make evb-px5_defconfig
make
To build rk3399 boards::
export BL31=/path/to/arm-trusted-firmware/to/bl31.elf
make evb-rk3399_defconfig
make
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 single boot image using binman and pad_cat.
To write an image that boots from an 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 configurations::
mmc dev 0
gpt write mmc 0 $partitions
Connect the USB-OTG cable between host and target device.
Launch fastboot at target::
fastboot 0
Upon successful gadget connection,host show the USB device like::
lsusb
Bus 001 Device 020: ID 2207:330c Fuzhou Rockchip Electronics Company RK3399 in Mask ROM mode
Program the flash::
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
^^^
Generating idbloader for SPI boot would require to input a multi image
image format to mkimage tool instead of concerting (like for MMC boot).
SPL-alone SPI boot image::
./tools/mkimage -n rk3399 -T rkspi -d spl/u-boot-spl.bin idbloader.img
TPL+SPL SPI boot image::
./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::
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 robin [1].
Create idbloader.img
.. code-block:: none
cd u-boot
./tools/mkimage -n px30 -T rksd -d rkbin/bin/rk33/px30_ddr_333MHz_v1.15.bin idbloader.img
cat rkbin/bin/rk33/px30_miniloader_v1.22.bin >> idbloader.img
sudo dd if=idbloader.img of=/dev/sda seek=64
Create trust.img
.. code-block:: none
cd rkbin
./tools/trust_merger RKTRUST/PX30TRUST.ini
sudo dd if=trust.img of=/dev/sda seek=24576
Create uboot.img
.. code-block:: none
rbink/tools/loaderimage --pack --uboot u-boot-dtb.bin uboot.img 0x200000
sudo dd if=uboot.img of=/dev/sda seek=16384
Note:
1. 0x200000 is load address and it's an optional in some platforms.
2. rkbin binaries are kept on updating, so would recommend to use the latest versions.
TODO
----
- Add Rockchip idbloader image building
- Add Rockchip TPL image building
- Document SPI flash boot
- Add missing SoC's with it boards list
