Introduction
|
||||
============
|
||||
|
||||
RK3328 key features we might use in U-Boot:
|
||||
* CPU: ARMv8 64bit quad-core Cortex-A53
|
||||
* IRAM: 36KB
|
||||
* DRAM: 4GB-16MB dual-channel
|
||||
* eMMC: support eMMC 5.0/5.1, suport HS400, HS200, DDR50
|
||||
* SD/MMC: support SD 3.0, MMC 4.51
|
||||
* USB: USB2.0 EHCI host port *2
|
||||
* Display: RGB/HDMI/DP/MIPI/EDP
|
||||
|
||||
evb key features:
|
||||
* regulator: pwm regulator for CPU B/L
|
||||
* PMIC: rk808
|
||||
* debug console: UART2
|
||||
|
||||
In order to support Arm Trust Firmware(ATF), we need to use the
|
||||
miniloader from rockchip which:
|
||||
* 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 rk3328.
|
||||
|
||||
Get the Source and prebuild binary
|
||||
==================================
|
||||
|
||||
> mkdir ~/evb_rk3328
|
||||
> cd ~/evb_rk3328
|
||||
> git clone https://github.com/ARM-software/arm-trusted-firmware.git
|
||||
> git clone https://github.com/rockchip-linux/rkbin
|
||||
> git clone https://github.com/rockchip-linux/rkflashtool
|
||||
|
||||
Compile ATF
|
||||
===============
|
||||
|
||||
> cd arm-trusted-firmware
|
||||
> make realclean
|
||||
> make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3328 bl31
|
||||
|
||||
Compile U-Boot
|
||||
==================
|
||||
|
||||
> cd ../u-boot
|
||||
> make CROSS_COMPILE=aarch64-linux-gnu- evb-rk3328_defconfig all
|
||||
|
||||
Compile rkflashtool
|
||||
=======================
|
||||
|
||||
> cd ../rkflashtool
|
||||
> make
|
||||
|
||||
Package image for miniloader
|
||||
================================
|
||||
> cd ..
|
||||
> cp arm-trusted-firmware/build/rk3328/release/bl31.bin rkbin/rk33
|
||||
> ./rkbin/tools/trust_merger rkbin/tools/RK3328TRUST.ini
|
||||
> ./rkbin/tools/loaderimage --pack --uboot u-boot/u-boot-dtb.bin uboot.img
|
||||
> mkdir image
|
||||
> mv trust.img ./image/
|
||||
> mv uboot.img ./image/rk3328evb-uboot.bin
|
||||
|
||||
Flash image
|
||||
===============
|
||||
Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
|
||||
|
||||
> ./rkflashtool/rkflashloader rk3328evb
|
||||
|
||||
You should be able to get U-Boot log message in console/UART2 now.
