前言

• 最近拿到 RT-Thread 柿饼派M7的开发板，默认运行的是RT-Thread Persim OS，不过我把固件给擦除了，无法开机了，所以先从最基本的启动下手
• 开发板板子SDEMMC，也就是板载 SD卡，所以无法使用全志的烧卡工具制作【启动卡】，RT-Thread 官方提供了可以烧写板载SD卡的xfel工具

xfel工具

• 全志 F133（d1s），进入FEL模式后，运行烧写，进入FEL模式，可以使用xfel工具进行各种烧写操作
• 默认当前的xfel版本不支持 SD卡的烧写（板载在线烧写），RT-Thread 提供的工具，增加了这个功能，所以很实用。
• 这里直接使用官方的xfel 工具进行操作，了解xfel 工具的使用方法
• https://github.com/xboot/xfel
• 这里直接下载 windows下的产物

xboot

• https://github.com/xboot/xboot，可以认为功能强大的bootloader，初步看了下，可用于初始化启动全志 F133
• git clone xboot的代码到 ubuntu，然后根据 xboot中的文档，编译xboot，生成 xboot.bin

运行xboot

• 经过了解，xboot.bin 可以使用 xfel 工具，写到 ddr中执行，这样比较的方便，当然后期软件固化，可以烧写到板载SD卡中
• 后面研究是否可以直接使用xboot 启动芯片，不再使用其他的 boot0之类的

ddr运行xboot

• 首先让开发板进入 FEL模式，有个按键可以在断电后按着，然后USB上电（OTG），松开按键即可进入FEL模式
• 在控制台，我使用RT-Thread ENV工具，输入 xfel version，如果正常，就可以直接操作了，如果无法找到FEL设备，就是安装一下驱动

• 操作命令，提前把编译好的xboot.bin，放在 xfel 工具目录下，或者可以找到的目录位置
• xfel ddr f133 初始化ddr，F133 内部有个64MB 的DDR RAM
• xfel write 0x40000000 xboot.bin，烧写 xboot.bin 到 DDR，烧写到 ddr 0x40000000 位置
• xfel exec 0x40000000，运行xboot，类似于uboot 的go命令

串口信息

• 接上DEBUG串口，可以查看串口的信息
