【风火轮YY3568开发板免费体验】第一章：开发环境搭建，系统替换为原生Linux
第一章：yy3568 内核开发环境搭建本章主要记录如何替换 yy3568 出厂的安卓系统（开发起来有点不纯粹，我更习惯在原生的linux上进行开发）。在替换系统的过程中，有一些要点和经验做一些记录：
yy3568 的 uart2 是 uart debug。波特率为1500000使用 loader 模式分区烧写镜像，涉及到使用parameter.txt查看分区信息，在loader模式中根据这些分区信息进行烧写在 debian源码中分别编译kernel,uboot以及buildroot对应的根文件系统在使用 buildroot 编译根文件系统的时候，出现了 su 命令切换 root 提示错误的问题，通过修改 buildroot 打包根文件系统的过程手动打包出来rootfs规避了这个问题。这里还简单描述下https://youyeetoo.cn/thread-6228-1-1.html主要参考资料：yy3568 wiki
1. 获取源码，编译本次编译我使用的是在一台 fedora35 的 pc机上编译 debian10 的源码，相关资料在风火轮的wiki中都有体现，具体链接是https://pan.baidu.com/s/1nynxvl6vnqpbsovkru8j7q?pwd=t6cg
下载下来后根据编译方法进行编译就行了，我选择的是分别编译uboot,kernel和rootfs(buildroot)。具体流程是：
# 解压cat yy3568-debian10.tar.gz.0* | tar -xzvcd yy3568-debian10git reset --hard head#编译./build.sh yy3568-debian10.mk#./build.sh 这一步我没有执行，因为我担心编译太耗时./build.sh uboot # 比较流畅，主要修改了几个配置，1. 修改 env 存储到 emmc 2. 设置 boot_delay 为 5,默认是0./build.sh kernel # 比较流畅，就是耗时./build.sh buildroot # 这一步特别耗费时间，并且还需要根据错误提示进行修错处理，我做的一些修改做了一个 patch 文件放在附件中，仅供参考./build.sh firmware # 将需要烧写的文件存放到根目录的 rockdev 目录，这样方便烧写#./build.sh updateimg # 这一步是打包成一个单独的 img，没有成功，所以采用了分区烧写执行完 ./build.sh firmware 之后就可以看到 rockdev 目录下的内容

2. 分区烧录文件因为我在 fedora 下没有打包出来一个完整的 img,所以就需要分区烧写（实际这样也方便，可以随时更新kernel，uboot或者rootfs，一般开发只用更新这些就可以）。这时候就出现了一个新的问题分区的地址该如何填写呢？通过查找文档，看到了一段描述：
测试确实可以读出来分区信息，按照分区信息填写将文件烧录进去就可以了。
3.引导启动因为默认的 bootcmd 会首先尝试 boot_android, 所以可以修改 bootcmd 直接启动 boot_fit.加快引导。因为打包出来的 boot.img 是 fit 的。
前面部分的关键引导日志如下，完整的我放到附件*附件：yy3568_log.zip中了。

yy3568 的 uart2 是 uart debug。波特率为1500000使用 loader 模式分区烧写镜像，涉及到使用parameter.txt查看分区信息，在loader模式中根据这些分区信息进行烧写在 debian源码中分别编译kernel,uboot以及buildroot对应的根文件系统在使用 buildroot 编译根文件系统的时候，出现了 su 命令切换 root 提示错误的问题，通过修改 buildroot 打包根文件系统的过程手动打包出来rootfs规避了这个问题。这里还简单描述下https://youyeetoo.cn/thread-6228-1-1.html主要参考资料：yy3568 wiki
1. 获取源码，编译本次编译我使用的是在一台 fedora35 的 pc机上编译 debian10 的源码，相关资料在风火轮的wiki中都有体现，具体链接是https://pan.baidu.com/s/1nynxvl6vnqpbsovkru8j7q?pwd=t6cg
下载下来后根据编译方法进行编译就行了，我选择的是分别编译uboot,kernel和rootfs(buildroot)。具体流程是：
# 解压cat yy3568-debian10.tar.gz.0* | tar -xzvcd yy3568-debian10git reset --hard head#编译./build.sh yy3568-debian10.mk#./build.sh 这一步我没有执行，因为我担心编译太耗时./build.sh uboot # 比较流畅，主要修改了几个配置，1. 修改 env 存储到 emmc 2. 设置 boot_delay 为 5,默认是0./build.sh kernel # 比较流畅，就是耗时./build.sh buildroot # 这一步特别耗费时间，并且还需要根据错误提示进行修错处理，我做的一些修改做了一个 patch 文件放在附件中，仅供参考./build.sh firmware # 将需要烧写的文件存放到根目录的 rockdev 目录，这样方便烧写#./build.sh updateimg # 这一步是打包成一个单独的 img，没有成功，所以采用了分区烧写执行完 ./build.sh firmware 之后就可以看到 rockdev 目录下的内容

2. 分区烧录文件因为我在 fedora 下没有打包出来一个完整的 img,所以就需要分区烧写（实际这样也方便，可以随时更新kernel，uboot或者rootfs，一般开发只用更新这些就可以）。这时候就出现了一个新的问题分区的地址该如何填写呢？通过查找文档，看到了一段描述：
测试确实可以读出来分区信息，按照分区信息填写将文件烧录进去就可以了。
3.引导启动因为默认的 bootcmd 会首先尝试 boot_android, 所以可以修改 bootcmd 直接启动 boot_fit.加快引导。因为打包出来的 boot.img 是 fit 的。
前面部分的关键引导日志如下，完整的我放到附件*附件：yy3568_log.zip中了。
