boards/lckfb-szpi-esp32s3: add sdmmc defconfig
Add SD card configuration for lckfb-szpi-esp32s3 board using
SDMMC peripheral in 1-bit mode with the following pin mapping:
- CLK: GPIO47
- CMD: GPIO48
- D0: GPIO21
Features enabled:
- ESP32S3 SDMMC driver
- FAT filesystem with long filename (LFN) support
- mkfatfs utility for on-device formatting
Usage:
mkfatfs -F 32 /dev/mmcsd1
mkdir -p /mnt/sd
mount -t vfat /dev/mmcsd1 /mnt/sd
Update documentation with sdmmc configuration details.

+Pin GPIO

+CLK GPIO47
+CMD GPIO48
+D0 GPIO21
+===== ======
+
+You can run the configuration and compilation procedure::
+
+ $ ./tools/configure.sh lckfb-szpi-esp32s3:sdmmc
+ $ make flash -j$(nproc) ESPTOOL_PORT=/dev/ttyUSB0
+
+Then format and mount the SD card::
+
+ # Format the SD card with FAT32
+ nsh> mkfatfs -F 32 /dev/mmcsd1
+
+ # Create mount point and mount
+ nsh> mkdir -p /mnt/sd
