In order to support Arm Trust Firmware(ATF), we can use either SPL or
|
|
|
|
|
miniloader from rockchip to do:
|
2016-07-19 13:17:01 +00:00
|
|
|
* do DRAM init
|
|
|
|
|
* load and verify ATF image
|
|
|
|
|
* load and verify U-Boot image
|
|
|
|
|
|
|
|
|
|
Here is the step-by-step to boot to U-Boot on rk3399.
|
|
|
|
|
|
|
|
|
|
Get the Source and prebuild binary
|
|
|
|
|
==================================
|
|
|
|
|
|
|
|
|
|
> mkdir ~/evb_rk3399
|
|
|
|
|
> cd ~/evb_rk3399
|
|
|
|
|
> git clone https://github.com/ARM-software/arm-trusted-firmware.git
|
2017-12-15 03:15:05 +00:00
|
|
|
> git clone https://github.com/rockchip-linux/rkbin.git
|
|
|
|
|
> git clone https://github.com/rockchip-linux/rkdeveloptool.git

|
|
2019-01-21 21:53:26 +00:00
|
|
|
|
|
|
|
|
Compile ATF
|
|
|
|
|
===========
|
2016-07-19 13:17:01 +00:00
|
|
|
|
|
|
|
|
> cd arm-trusted-firmware
|
|
|
|
|
> make realclean
|
|
|
|
|
> make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl31
|
|
|
|
|
|
2019-01-21 21:53:26 +00:00
|
|
|
Get bl31.elf in this step, copy it to U-Boot root dir:
|
|
|
|
|
> cp build/rk3399/release/bl31/bl31.elf ../u-boot/
|
|
|
|
|
|
2017-12-15 03:15:05 +00:00
|
|
|
Or you can get the bl31.elf directly from Rockchip:
|
2019-01-21 21:53:26 +00:00
|
|
|
> cp rkbin/rk33/rk3399_bl31_v1.00.elf ../u-boot/bl31.elf
|
2017-12-15 03:15:05 +00:00
|
|
|
|
|
|
|
|
|
2019-01-21 21:53:26 +00:00
|
|
|
Compile U-Boot
|
|
|
|
|
==============
|
2016-07-19 13:17:01 +00:00
|
|
|
|
|
|
|
|
> cd ../u-boot
|
2017-12-15 03:15:05 +00:00
|
|
|
> export ARCH=arm64
|
|
|
|
|
> export CROSS_COMPILE=aarch64-linux-gnu-
|
|
|
|
|
> make evb-rk3399_defconfig
|
|
|
|
|
for firefly-rk3399, use below instead:
|
|
|
|
|
> make firefly-rk3399_defconfig
|
|
|
|
|
> make
|
|
|
|
|
> make u-boot.itb
|
2016-07-19 13:17:01 +00:00
|
|
|
|
2017-12-15 03:15:05 +00:00
|
|
|
Get spl/u-boot-spl.bin and u-boot.itb in this step.
|
2016-07-19 13:17:01 +00:00
|
|
|
|
2019-01-21 21:53:26 +00:00
|
|
|
Compile rkdeveloptool
|
|
|
|
|
=====================
|
|
|
|
|
|
|
|
|
|
Get rkdeveloptool installed on your Host in this step.
|
|
|
|
|
|
|
|
|
|
Follow instructions in latest README, example:
|
2018-06-03 14:50:20 +00:00
|
|
|
> cd ../rkdeveloptool
|
2017-12-15 03:15:05 +00:00
|
|
|
> autoreconf -i
|
|
|
|
|
> ./configure
|
2016-07-19 13:17:01 +00:00
|
|
|
> make
|
2017-12-15 03:15:05 +00:00
|
|
|
> sudo make install
|
2016-07-19 13:17:01 +00:00
|
|
|
|
2017-12-15 03:15:05 +00:00
|
|
|
Both origin binaries and Tool are ready now, choose either option 1 or
|
|
|
|
|
option 2 to deploy U-Boot.

|
|
|
|
|
-------------------------------
|
|
|
|
|
Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
|
|
|
|
|
> rkdeveloptool db rkbin/rk33/rk3399_loader_v1.08.106.bin
|
|
|
|
|
> rkdeveloptool wl 64 u-boot/idbspl.img
|
|
|
|
|
> rkdeveloptool wl 0x4000 u-boot/u-boot.itb
|
|
|
|
|
> rkdeveloptool rd
|

|
|
|
|
|
----------------------------------------
|
|
|
|
|
Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
|
|
|
|
|
> rkdeveloptool db rkbin/rk33/rk3399_loader_v1.08.106.bin
|

|
|
|
|
|
> rkdeveloptool wl 0x4000 u-boot/uboot.img
|
|
|
|
|
> rkdeveloptool wl 0x6000 u-boot/trust.img
|
|
|
|
|
> rkdeveloptool rd
|
|
|
|
|
|
|
