关于esp32使用tf卡的异常请教

Postby xuankong » Mon Aug 26, 2024 5:15 am

我打了一块验证TF的pcb,d0,d1,d2,d3,clk,cmd都10k上拉:

但是通过1线sdmmc尝试访问tf卡的时候始终报错如下:

我通过vspi的方式是可以访问tf卡的,但是sdmmc方式,不论是1线还是4线都不行
电路上面已经经过如下尝试:
1,d0,d1,d2,d3,clk,cmd 全上拉;
2,clk不上拉,其他上拉;

连接线也是检查好多天了

折腾好多天了,实在想搞明白是怎么回事,谢谢,期待有个回复。

换成了s3 ,1线sdmmc方式可以读取 tf卡了,但是esp32 版本怎么都不行,所以这个问题到底是发生了啥?
目前看来同我的tf 的pcb上的电阻是否上下拉没有关系的。
