Title: ESP32-EVB-EA-IND Rev K - SD Card Mount and use
Post by: moises on March 28, 2024, 08:08:09 PM
Hello everybody

I'm using a ESP32-EVB-EA-IND Rev K board but I can't seem to get the SD card to mount.
I keep having the error:

[E][sd_diskio.cpp:739] sdcard_mount(): f_mount failed 0x(3)

I've tried to the the SD.begin() with:
GPIO 14
GPIO 15
GPIO 02

And all of them gave me the same error.

Can someone please help me?

Did you configure your code for 1-bit SD mode?

Did you try our demo for the SD card:
