[已解决]ESP32S3无法挂载EMMC芯片

Postby heipppppp » Wed Nov 24, 2021 6:03 am

硬件：ESP32-S3-DevKitC-1
环境：ubuntu+vscode
IDF版本：v4.4
问题描述：
我想使用一个8线的mmc芯片作为外部存储，但是当我稍微修改例程后，发现无法挂载文件系统

我把
Code: [Select all] [Expand/Collapse]
  1.  slot_config.width = 8;

改成
Code: [Select all] [Expand/Collapse]
  1.  slot_config.width = 1;

就成功了，目前还不知道为什么，先去查找资料再说
