ESP32 Forum

Hello,

I get a issue when I initialise PSRAM and then use SD-Card with on my custom ESP32-S3 board.
If I activate the Option Initialize "SPI RAM during startup" the sdcard can not be mounted.
If the SD-Card format option is activated, the ESP32-S3 will destroy the file system.

Here is the Error which I get from mount function

The pinning is correct, because if I deactivate the option the SD-Card is mounted correct.
Thanks for your help

So you've checked that you're not trying to use an IO pin allocated to the PSRAM for the SD card?

Yes already Double checked that. There is no Pin allocated from PSRAM to SD Card based in espressif Datasheet.

Here is the pinning:
#define BSP_SD_HOST_CMD (GPIO_NUM_14)
#define BSP_SD_HOST_CLK (GPIO_NUM_17)
#define BSP_SD_HOST_D0 (GPIO_NUM_2)
#define BSP_SD_HOST_D1 (GPIO_NUM_4)
#define BSP_SD_HOST_D2 (GPIO_NUM_12)
#define BSP_SD_HOST_D3 (GPIO_NUM_13)
#define BSP_SD_DET (GPIO_NUM_21)
#define BSP_SD_ENABLE (GPIO_NUM_8)

The same issue is if I use one Data width 1.

Im having the exact same problem. Did you find a solution already?
