环境搭建

工具链

命令行编译

在进行命令行编译之前,需要根据你的操作系统,选择对应的工具链,并配置到系统环境变量,并安装了 make 或者 ninja 工具,然后才能进行下面操作。更详细的搭建过程,参考 BouffaloSDK 环境搭建.

  • 进入要编译的 demo 目录,且该目录下有 main.cMakefile 文件
  • 执行下面命令即可,以 BL616 为例
cd examples/helloworld
make CHIP=bl616 BOARD=bl616dk
  • 如果使用 BL808 或者 BL606P ,需要添加 CPU_ID
cd examples/helloworld
make CHIP=bl808 BOARD=bl808dk CPU_ID=m0

如果你想使用 ninja 编译,你可以尝试:

cd examples/helloworld
make ninja CHIP=bl616 BOARD=bl616dk
cd examples/helloworld
make ninja CHIP=bl808 BOARD=bl808dk CPU_ID=m0

CDK 编译

TODO

调试

当前仅支持使用 CKLink 调试。详细参考 BouffaloSDK 调试指南

固件烧录

需要注意,如果使用的是 linux,linux 由于权限问题会拒绝访问串口设备,所以,为了方便后续使用,将你自己的用户名添加到 dialout 中。然后重启 linux 生效。或者在命令的前面加上 sudo

sudo usermod -aG dialout xxx # xxx 是你自己的用户名
cd examples/helloworld
make flash CHIP=chip_name COMX=xxx # chip_name should be bl602/bl702/bl616/bl808/bl606p, COMX in Windows, /dev/ttyxxx in Linux
  • 如果使用 BL808 或者 BL606P ,需要添加 CPU_ID
cd examples/helloworld
make flash CHIP=chip_name CPU_ID=m0 COMX=xxx # chip_name should be bl602/bl702/bl616/bl808/bl606p, COMX in Windows, /dev/ttyxxx in Linux

如果使用串口烧录而非 USB 烧录,不同的 USB2TTL 芯片支持的最高波特率不一样,烧录的时候需要注意。

芯片 波特率
ch340 <= 500K
cp2102 <= 2M
ft232 <= 2M
bl702 <= 8M
bl616 <= 10M
