I'm not able to connect the a microSD card with the ESP32. I AM able to connect to the same card/reader with an Arduino Uno, so I know the the card and reader are OK.
When I try to connect I get the following
Code: Select all
[W][sd_diskio.cpp:491] ff_sd_initialize(): READ_OCR failed: 0 [E][sd_diskio.cpp:739] sdcard_mount(): f_mount failed 0x(3)
I have looked at tons of posts across the internet, but have not been able to get this to work. Any ideas?
