编译系统源码后,打包后生成的系统文件称之为固件。固件一般为.img
格式。把固件下载到开发板或者产品上的过程称之为 烧写固件 。
R128 有两种烧录模式,分别为 USB 烧录与UART烧录。烧录模式以芯片 RST 时 PA1,PA2 引脚高低电平控制。
R128 Module 默认配置为 USB 烧录,PA2 已经在模组通过下拉电阻下拉。
PA1 | PA2 | 模式 |
---|---|---|
1 | 1 | 非法模式 |
1 | 0 | 正常启动 |
0 | 1 | UART 下载 |
0 | 0 | USB 下载 |
R128 支持使用 USB 烧写系统。对于 Windows 用户可以使用 PhoenixSuit 进行烧写。是最常用的烧写工具,通过数据线将PC和开发板连接,把固件烧到开发板上。PhoenixSuit 支持分区烧写,适用于开发和小规模生产使用。
FEL
键,然后点击 RESET
键重置开发板RESET
点击后 PhoenixSuit 会自动进入烧录模式,开始下载在开发的时候,会遇到只需要烧录单独分区的情况,例如只修改了 RV 核心的固件,不需要全盘下载。就可以选择单独分区烧录功能。
Linux 版本 PhoenixSuit 支持的发行版本包括 Ubuntu、Fedora、Redhat 及 CentOS 等几个常见的发行版本。目前驱动已经可以支持 4.11.0 版本以上内核,建议安装内核版本号大于4.11.0 的 Linux 发行版本。
sudo apt install dkms dctrl_tools
来安装!
sudo ./PhoenixSuit.run
来运行安装程序。FEL
键,然后点击 RESET
键重置开发板使其进入下载模式lsusb
查看 USB 设备,找到 ID 1f3a:efe8
,找到即安装完成。sudo ./PhoenixSuit rtos_xxx_uart0_16Mnor.img
下载烧录 rtos_xxx_uart0_16Mnor.img
Clos image OK!
时,按住 FEL
引脚,点击 RESET
键使芯片进入下载模式sudo ./PhoenixSuit rtos_xxx_uart0_16Mnor.img
下载烧录 rtos_xxx_uart0_16Mnor.img
,先进入下载模式。Dev Plugout The Device Path is /dev/aw_efex0
会卡住sudo ./PhoenixSuit rtos_xxx_uart0_16Mnor.img
下载命令。会出现 Errpr!!!: PnpFesIn Error!
这是因为烧录启动时的 USB 模式不匹配导致的,之前的操作导致USB进入了 FFFF
模式。此时需要按住 FEL
引脚,点击 RESET
键使芯片进入下载模式重新下载(下载模式会显示 02B3
)PhoneixSuit_MacOS.zip
chmod 777 ./phoenixsuit
赋予运行权限./phoenixsuit rtos_xxx_uart0_16Mnor.img
下载烧录 rtos_xxx_uart0_16Mnor.img

R128 支持使用 UART 烧写系统。
请注意:R128 Module 在硬件上下拉了 PA2 引脚,默认配置为USB下载模式。如果希望使用 UART 下载需要摘除 PA2 下拉电阻,或者外部上拉 PA2 到 3V3
PA2 下拉电阻为 47K,可以直接上拉 PA2 到 3V3 进入UART下载模式
PhoenixMC
点击 刷新
,注意在下载过程中请断开各类串口监视器,不能占用串口,否则刷新找不到对应串口。如果选择太高的波特率会导致通讯错误,板载的 CH340C 仅支持最大2000000波特率
刷新
选择对应的串口如果出现 Open uart error!
则表示没有关闭串口助手或者选择错了串口。

文件注意:USB 烧写使用的是专有格式,需要 PhoenixSuit 解析并烧录,UART 烧写使用的是通用格式,为内置 SPI NOR 的镜像文件。
