What is the expected behavior?

The SD card should've been initialized and mounted in SDMMC mode normally, as it did in SPI mode.

What is the actual behavior?

The SD card appears to give responses to some commands during initialization, as the logs notify that the card present is an SDHC/SDXC card. However, initialization later fails with a 0x107, suggesting that the SD card did not respond to a command (or several).

Steps to reproduce.

1. Hook up the SD card to the board. GPIO choice shouldn't matter given it's an ESP32-S3, but these are the GPIOs I used during testing:

SD card	GPIO
CLK	14
CMD	13
D0	12
D1	11
D2	10
D3	9

2. Make a copy of the SDMMC example.
3. Configure the example's GPIOs in menuconfig.
4. Flash the project into the board.

More Information.

• I have tried both 1-bit and 4-bit SDMMC mode, both of which do not work. SPI mode works just fine.
• I have pull-up resistors in every line. Removing the pull-ups doesn't make a difference in the results. Note that I'm using 4.7k resistors instead of 10k as I currently don't have enough 10k resistors for all of the lines.
• I have tried two different SD cards, both of which generate the same results. One is 2GB, the other one is 8GB, and they're both formatted as FAT32.
• I have tried using different GPIOs.
• I have tried changing the max_freq_khz to SDMMC_FREQ_PROBING, SDMMC_FREQ_DEFAULT and SDMMC_FREQ_HIGHSPEED.
• I have tried using older versions of ESP-IDF, such as v5.1 and v5.1.2.

Seems like the real issue all this time was the power supply. I hooked up an external 3.3V power supply to the SD card and it started working perfectly. 4-bit won't work (for some reason, sdmmc_init_ocr still timeouts if DAT1 and DAT2 aren't grounded, even when trying to initialize the card as 4-bit), but 1-bit is more than enough for my project.

I will be closing the issue now.

Nice to hear you have solved the issue. Thanks for the update
