SD card driving with SPI

Postby m3ayko83 » Sat Jan 26, 2019 9:50 am

i try to make the demo code for SD card work but i get the error
Failed to initialize the card (ESP_ERR_INVALID_STATE). Make sure SD card lines have pull-up resistors in place. attached is my schematic for the SD card,

I (1246) SD_CARD_TASK: Initializing SD card
I (1246) SD_CARD_TASK: Using SPI peripheral
I (1250) gpio: GPIO[22]| InputEn: 0| OutputEn: 1| OpenDrain: 0| Pullup: 0| Pulldown: 0| Intr:0
I (1281) gpio: GPIO[23]| InputEn: 0| OutputEn: 0| OpenDrain: 0| Pullup: 1| Pulldown: 0| Intr:0
I (1281) gpio: GPIO[19]| InputEn: 0| OutputEn: 0| OpenDrain: 0| Pullup: 1| Pulldown: 0| Intr:0
I (1289) gpio: GPIO[18]| InputEn: 0| OutputEn: 0| OpenDrain: 0| Pullup: 1| Pulldown: 0| Intr:0

Hi m3ayko83,

We can't tell exactly what's the problem from the information you given. Personally I guess it's a driver initialization issue.
Can you provide your code and the complete log for us to help you?
