程序烧写
-
注意：当前bsp需要在linux环境下才能编译
-
测试环境：Ubuntu21
Step 1: 下载sdk
menuconfig
pkgs --update
Step 2: 编译
scons -c
scons
gcc version >= 6.x.x
Step 3: 烧写
编译会生成uf2文件
按住boot键，再短按重启进入u盘烧写模式,此时将rp2350插入电脑会显示一个u盘
- 复制 rtthread-pico.uf2 文件到u盘中
- 自动重启运行
或者进入boot模式后输入以下命令烧写
picotool load rtthread-pico.uf2
picotool reboot
运行结果
输出的信息如下
