esp_vfs_fat_sdmmc_unmount() is now deprecated, you can use esp_vfs_fat_sdcard_unmount() instead. This API is deprecated in previous IDF versions, but without deprecation warning and migration guide. Since IDF v5.1, calling this esp_vfs_fat_sdmmc_unmount() API will generate deprecation warning.

SPI Flash Driver

XMC-C series flash suspend support has been removed. According to feedback from the flash manufacturer, in some situations the XMC-C flash would require a 1ms interval between resume and next command. This is too long for a software request. Based on the above reason, in order to use suspend safely, we decide to remove flash suspend support from XMC-C series. But you can still force enable it via CONFIG_SPI_FLASH_FORCE_ENABLE_XMC_C_SUSPEND. If you have any questions, please contact espressif business support.
