Here is the step-by-step to boot to U-Boot on Rock960 boards.
|
||
|
|
|
||
|
|
Get the Source and prebuild binary
|
||
|
|
==================================
|
||
|
|
|
||
|
|
> git clone https://github.com/96rocks/rkbin.git
|
||
|
|
> git clone https://github.com/rockchip-linux/rkdeveloptool.git
|
||
|
|
|
||
|
|
Compile the U-Boot
|
||
|
|
==================
|
||
|
|
|
||
|
|
> cd ../u-boot
|
||
|
|
> cp ../rkbin/rk33/rk3399_bl31_v1.00.elf ./bl31.elf
|
||
|
|
> export CROSS_COMPILE=aarch64-linux-gnu-
|
||
|
|
> make rock960-rk3399_defconfig
|
||
|
|
> make
|
||
|
|
|
||
|
|
Compile the rkdeveloptool
|
||
|
|
=========================
|
||
|
|
|
||
|
|
Follow instructions in latest README
|
||
|
|
> cd ../rkdeveloptool
|
||
|
|
> autoreconf -i
|
||
|
|
> ./configure
|
||
|
|
> make
|
||
|
|
> sudo make install
|
||
|
|
|
||
|
|
Package the image
|
||
|
|
=================
|
||
|
|
|
||
|
|
Package the image for U-Boot SPL(option 1)
|
||
|
|
--------------------------------
|
||
|
|
> cd ..
|
||
|
|
> tools/mkimage -n rk3399 -T rksd -d spl/u-boot-spl.bin idbspl.img
|
||
|
|
|
||
|
|
Get idbspl.img in this step.
|
||
|
|
|
||
|
|
Package the image for Rockchip miniloader(option 2)
|
||
|
|
------------------------------------------
|
||
|
|
> cd ../rkbin
|
||
|
|
> ./tools/loaderimage --pack --uboot u-boot/u-boot-dtb.bin uboot.img 0x200000
|
||
|
|
|
||
|
|
> ../u-boot/tools/mkimage -n rk3399 -T rksd -d rk3399_ddr_933MHz_v1.08.bin idbloader.img
|
||
|
|
> cat ./rk33/rk3399_miniloader_v1.06.bin >> idbloader.img
|
||
|
|
|
||
|
|
Get uboot.img and idbloader.img in this step.
|
||
|
|
|
||
|
|
Bootloader storage options
|
||
|
|
==========================
|
||
|
|
|
||
|
|
There are a few different storage options for the bootloader.
|
||
|
|
This document explores two of these: eMMC and removable SD/MMC.
|
||
|
|
|
||
|
|
Flash the image to eMMC
|
||
|
|
=======================
|
||
|
|
|
||
|
|
Flash the image with U-Boot SPL(option 1)
|
||
|
|
-------------------------------
|
||
|
|
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
|
||
|
|
|
||
|
|
Flash the image with Rockchip miniloader(option 2)
|
||
|
|
----------------------------------------
|
||
|
|
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 0x40 idbloader.img
|
||
|
|
> rkdeveloptool wl 0x4000 uboot.img
|
||
|
|
> rkdeveloptool wl 0x6000 ./img/rk3399/trust.img
|
||
|
|
> rkdeveloptool rd
|
||
|
|
|
||
|
|
Create a bootable SD/MMC
|
||
|
|
========================
|
||
|
|
|
||
|
|
The idbspl.img contains the first stage, and the u-boot.img the second stage.
|
||
|
|
As explained in the Rockchip partition table reference [1], the first stage
|
||
|
|
(aka loader1) start sector is 64, and the second stage start sector is 16384.
|
||
|
|
|
||
|
|
Each sector is 512 bytes, which means the first stage offset is 32 KiB,
|
||
|
|
and the second stage offset is 8 MiB.
|
||
|
|
|
||
|
|
Note: the second stage location is actually not as per the spec,
|
||
|
|
but defined by the SPL. Mainline SPL defines an 8 MiB offset for the second
|
||
|
|
stage.
|
||
|
|
|
||
|
|
Assuming the SD card is exposed by device /dev/mmcblk0, the commands
|
||
|
|
to write the two stages are:
|
||
|
|
|
||
|
|
> dd if=idbspl.img of=/dev/mmcblk0 bs=1k seek=32
|
||
|
|
> dd if=u-boot.itb of=/dev/mmcblk0 bs=1k seek=8192
|
||
|
|
|
||
|
|
Setting up the kernel and rootfs is beyond the scope of this document.
|
||
|
|
|
||
|
|
And that is it
|
||
|
|
==============
|
||
|
|
|
||
|
|
You should be able to get U-Boot log in console/UART2(baurdrate 1500000)
