Postby z43740979 » Mon Jun 12, 2017 3:20 am

I downlaod SD card example from ESP-IDF and
always got this error:
[0;31mE (1216) example: Failed to initialize the card (265). Make sure SD card lines have pull-up resistors in place.

Have you made sure the SD card lines have pull-up resistors in place? More generally, what's the hardware you're working with?
