rock5b uboot制作

git clone https://github.com/u-boot/u-boot.git

cd u-boot

make rock5b-rk3588_defconfig

 make　　　　# 出错后安装缺少的包

apt install swig

apt install python-is-python3　　#依然出错

 apt install python3-dev　　　　不报错了

依然报错：　　binman: Filename 'rockchip-tpl' not found in input path

参考　　https://u-boot.readthedocs.io/en/latest/board/rockchip/rockchip.html

git clone --depth 1 https://github.com/rockchip-linux/rkbin

cd u-boot

export BL31=../rkbin/bin/rk35/rk3588_bl31_v1.33.elf

export ROCKCHIP_TPL=../rkbin/bin/rk35/rk3588_ddr_lp4_2112MHz_lp5_2736MHz_v1.09.bin

make CROSS_COMPILE=aarch64-linux-gnu-

这回报错：　　

binman: Filename '../rkbin/bin/rk35/rk3588_ddr_lp4_2112MHz_lp5_2736MHz_v1.09.bin' not found in input path (.,.,./board/radxa/rock5b-rk3588,arch/arm/dts) (cwd='/root/download/u-boot')

make: *** [Makefile:1115: .binman_stamp] Error 1

去找文件发现：

 改为： export ROCKCHIP_TPL=../rkbin/bin/rk35/rk3588_ddr_lp4_2112MHz_lp5_2736MHz_v1.12.bin

重新 make CROSS_COMPILE=aarch64-linux-gnu- -j8

出错：

binman: Filename '../rkbin/bin/rk35/rk3588_bl31_v1.33.elf' not found in input path (.,.,./board/radxa/rock5b-rk3588,arch/arm/dts) (cwd='/root/download/u-boot')

make: *** [Makefile:1115: .binman_stamp] Error 1

改为：　　export BL31=../rkbin/bin/rk35/rk3588_bl31_v1.40.elf

make依然出错： 

Wrote map file './simple-bin.map' to show errors

binman: Node '/binman/simple-bin/fit': subnode 'images/@atf-SEQ': Failed to read ELF file: Python: No module named 'elftools'

make: *** [Makefile:1115: .binman_stamp] Error 1

尝试　　　　apt install python3-pyelftools　　　　成功！

重新 make clean &&  make CROSS_COMPILE=aarch64-linux-gnu- -j8　　　　无错误，成功

插入我的8gSD卡读卡器到开发板然后　　fdisk -l

 销毁磁盘数据　　dd if=/dev/urandom of=/dev/sda　　　　非常耗时间，谨慎

dd if=u-boot-rockchip.bin of=/dev/sda seek=64

sync

取下原SD卡，拔下读卡器中sd卡插入rock5b开发板SD卡卡槽，开机，串口终端1500000波特率，打印出信息
