I have tested the SD_card_example and it works on my ESP32 P4 development board. However, I had to adjust the pins in the menuconfig. My settings are:
(44) MOSI GPIO number
(39) MISO GPIO number
(43) CLK GPIO number
(42) CS GPIO number

Maybe it will help you with your project.

Thank you for your help. I'm using the bsp_sdcard_mount() API from the managed components. Normally, this API works without any issues, but in this particular demo, it’s causing the error I mentioned earlier. Since the API is official and has been well-tested, I’m puzzled as to why it’s not working in this case. Could you provide some insight into this?

[chegewara]

Normally yes, but i believe that all examples for P4 may have incorrectly assigned pins for peripherals.
I am strongly suggesting to check always with schematics.
The same situation is with some example (dont remember which one) and ethernet.

[liujkek22]

Thank you for your suggestion. I followed your advice and checked the assigned pins. Interestingly, I conducted a test in another project, such as "lvgl_demo_v8/v9." In that test, I performed the following steps:

1. Called bsp_sdcard_mount();
2. Tested opening and reading a file

Everything worked fine. However, in the ESP_UI_DEMO project, the same steps don't seem to work as expected. This is quite puzzling.

If the bsp_sdcard_mount(); API were faulty, it wouldn't work in the other project either, so the issue might be related to some setting or an API conflict within the ESP_UI_DEMO project.

[st3m0r]

same problem, if you are using the wifi than mmc doesn't work, only sd_spi

[Horion0415]

Currently, the SD card initialization method conflicts with esp_hosted, but this issue has been resolved and is being merged into ESP-BSP. If you need to test it urgently, you can use the PR (espressif/esp-bsp#401).
