Hi,
Is it possible to format an SD card as FAT32 at runtime using ESP-IDF ?
Thanks!

// Compatibility definition
typedef esp_vfs_fat_mount_config_t esp_vfs_fat_sdmmc_mount_config_t;

Re: Formatting SD card
Still not really understand how to get it to format on runtime.
Having such a thing in an unreachable esp32cam would be great, when the data corrupts. (it happened..)
this is 'if mount fails'..
