Supported Targets	ESP32	ESP32-C2	ESP32-C3	ESP32-C6	ESP32-H2	ESP32-S2	ESP32-S3

This test app runs a few FATFS test cases in a FAT-formatted SD card.

These tests require a development board with an SD card slot:

• ESP32-WROVER-KIT
• ESP32-S2 USB_OTG
• ESP32-C3-DevKit-C with an SD card breakout board

The test cases are split between [sdmmc] and [sdspi]. Only a few tests are executed for sdspi, though. The app could be refactored to ensure that a similar set of tests runs for sdmmc and sdspi.

See ../README.md for more information about FATFS test apps.
