Problem with SD Card example
Posted: Wed May 23, 2018 6:37 pm
Hi, I'm trying to get my SD card up and running. I have it set for SPI mode. I have a microSD breakout board from "WaveShare" that has 10K pullup resistors on all of the pins, save ground. I've wired it to the default GPIO pins from the example program, but when I run the monitor I get the following errors:
E (314) sdmmc_cmd: sdmmc_card_init: send_if_cond (1) returned 0x108
E (314) example: Failed to initialize the card (264). Make sure SD card lines have pull-up resistors in place.
Any ideas what I could be doing wrong? I looked through the forums, but most of the threads were of people using SD mode (and the problems there moved me towards trying to use SPI mode).
Thanks...
