今天想用下 I2S，看泽哥的教程配置
（十四）零基础开发小安派-Eyes-S1【外设篇】——I2S - 小安派&M61零基础开发教程（官方） - 物联网开发者社区-安信可论坛 - Powered by Discuz! (ai-thinker.com)
我按教程步骤复制了8388的库
修改了代码
CMakeLists.txt 和 flash_prog_cfg.ini 也修改了
复制好了 main.c 文件
结果无法编译
发现，CMakeLists.txt 不添加这一行，可以编译，但是喇叭没音，
sdk_set_linker_script($ENV{BL_SDK_BASE}/bsp/board/bl616dk/bl616_flash_old.ld)
添加了这一行，报老多错误了
这是报错日志
