SDMMC example only works on one board
Posted: Thu Jul 03, 2025 7:10 pm
Hellooo
I am trying to flash the SDMMC example from the IDF github: https://github.com/espressif/esp-idf/tr ... card/sdmmc. I have three boards:
1) a ESP32S3-WROOM-1
2) a ESP32S3-WROOM-2
3) a ESP32S3-WROOM-1 N16R8
I am in 1-bit mode with CMD(pin 35), CLK(pin 2), D0(pin 37) on all boards.
The example flashes fine for the first board.
The example gives me these logs infinitely repeating for the second board:
These are the logs I get for the third board. These do not repeat.
I am hooking up the SD card to a 9 pin SD card module that has internal 10k pullups. Yes, the SD card has been formatted to FAT32. I have used different pin assignments on the third board with no avail.
Any help would be appreciated.

I (371) main_task: Returned from app_main()I am hooking up the SD card to a 9 pin SD card module that has internal 10k pullups. Yes, the SD card has been formatted to FAT32. I have used different pin assignments on the third board with no avail.
Any help would be appreciated.
