关于esp32使用tf卡的异常请教
Posted: 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。
但是通过1线sdmmc尝试访问tf卡的时候始终报错如下：

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。
