rt smart SDIO驱动问题

发布于 2022-01-28 16:38:27 浏览：851 订阅该版

最近把ART smart pi的程序跑在正点原子的阿尔法开发板上面，系统已经成功的启动并且运行了。测试发现，在访问SD卡时，如果访问根目录正常，访问的2级目录以下就失败了，分析是SDIO驱动的问题。还有等待详细深入的分析。

熊大，这个版本的rt smart中的librtthread.a无法连接生成可执行程序，我替换成1月26日（SHA1 ID:2407d4937da079bb5cc135260a2f4e741ac68beb）可以正常链接生成可执行程序，我使用的window来编译的。具体连接失败记录如下：编译生成其他应用的app也同样无法链接。
