I'm trying to get my esp32 wroom32 to get to work with an sd-card reader in sdmmc 4-line mode. The spi and 1-line modes are working, but the 4-line mode isn't.
I'm using the sdcard example:
- I've put six 10k pullup resistors on the pins
- I have already used the "set_flash_voltage 3.3V" command so the GPIO12 pin isn't the problem
- When I'm flashing the esp the GPIO2 pin is on the GND, and when I'm monitoring it's on the 10k pullup
- I'm using a breadbord so I added the next line to my code : host.max_freq_khz = SDMMC_FREQ_PROBING;
The log file:
Code: Select all
