I have uncomented the line and rebuilt, but it doesn t work. I get this :

E (433) sdmmc_req: handle_idle_state_events unhandled: 00000004 00000000
E (434) sdmmc_cmd: sdmmc_card_init: send_op_cond (1) returned 0x107
Card Mount Failed

I am trying to use SD card of rev B board.
I have tried the example of https://github.com/espressif/arduino-es ... braries/SD.
No way to make it work!
There is any way (example) of accessing SD card?
A new or different library is required?
