RK3588S开发板编译

自己购买了RK3588S的firefly的开发板，这里记录firefly板子的sdk编译方法。

Wiki地址

https://wiki.t-firefly.com/zh_CN/ROC-RK3588S-PC/linux_compile.html#huo-qu-sdk

仓库地址

firefly的gitlab仓库地址如下

https://gitlab.com/firefly-linux

拉取SDK

repo init --no-clone-bundle --repo-url https://gitlab.com/firefly-linux/git-repo.git -u https://gitlab.com/firefly-linux/manifests.git -b master -m rk3588_linux_release.xml 这里拉取在我的环境会报错，主要如下

DeprecationWarning: the imp module is deprecated 这里好像是和python3不支持import imp模块，如果默认是python3的情况下，则需要修改为

import importlib

str object has no attribute decode 然后继续运行，会出现如上错误，这里错误是没办法decode，根据百度搜索可知，去掉git_config.py内的decode函数即可。
firefly的repo推荐使用python2 通过提示可知道，repo推荐你去使用python2，这里修改python为python2即可

ln -sf /usr/bin/python2 /usr/bin/python

同步代码

跟着文档走，直接如下命令同步即可

.repo/repo/repo sync -c --no-tags
.repo/repo/repo start firefly --all

后续可以使用以下命令更新 SDK:

.repo/repo/repo sync -c --no-tags

切换分支

这里默认分支用tag: rk3588/linux_release_v1.1.1d。需要主动切一下

编译uboot

注意uboot的make.sh，这里如果默认的CROSS_COMPILSE_ARM64变量有问题需要根据实际情况修改，如果没问题就无需修改注意：编译uboot需要rkbin仓库，如没有rkbin仓库，则编译会因为无法编译miniloader而失败


-CROSS_COMPILE_ARM64=../prebuilts/gcc/linux-x86/aarch64/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-
+# CROSS_COMPILE_ARM64=../prebuilts/gcc/linux-x86/aarch64/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-
+CROSS_COMPILE_ARM64=YOUR_PATH/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-

编译命令如下


make rk3588_defconfig firefly-linux.config && ./make.sh

编译完成之后，会生成如下文件

uboot.img rk3588_spl_loader_v1.11.112.bin

修改

uboot通常不打开pcie的phy识别usb3.0，这里默认打开即可

firefly的日志比较烦人，可以去掉

uboot提示Bus usb@xxxxxxxx: usb maximum-speed not found 比较奇怪，可以显示指明usb3为super speed,其实默认就是super speed。感觉不舒服的可以去掉（强迫症）

uboot阶段开机慢，这里regulator这里上电故意停了1.2S,去掉也不影响

编译内核

编译内核主要选择好了设备树和配置即可，rk3588s-roc-ps-v1.0的配置如下


export ARCH=arm64
export CROSS_COMPILE=aarch64-linux-gnu-
make rockchip_linux_defconfig rk3588_linux.config firefly-linux.config
make roc-rk3588s-pc-mipi101-M101014-BE45-A1.img -j8
