Hi, the issue isn't fully clear based on the current description. Could you please share your custom or modified code to help us better understand the issue?

Hello, Yes, you can use a 64GB SD card with the ESP32-C6. You can use it on the SPI interface. Please refer to this example: https://github.com/espressif/esp-idf/tree/master/examples/storage/sd_card/sdspi . Using exFAT requires purchasing a license from Microsoft, and we do not support exFAT in IDF....

I'm not sure why you're adding the esp_vfs.h file to the `esp-idf\components\spi_flash\sim\stubs\vfs\include` directory. It is present at `esp-idf/components/vfs/include/esp_vfs.h`. However regarding the "esp_vfs.h: No such file or directory" issue, you need to include the `spi_flash\sim\stubs\vfs\i...

Hi @plusorc, Could you please try the same example on IDF v5.2? The issue you are facing has already been addressed in this version.

Question 2 : Have you already managed to flush the things you had writen in a file without closing it (Using FAT FileSystem and VFS component) ? This would enable me to write things in my file without opening and closing it. => Maybe it would be faster ? You can check a config option called "Enable...

Hi, I'm not sure why you need to know the erase_size for using LFS. Check out the IDF examples at https://github.com/espressif/esp-idf/tr ... lash_fatfs and https://github.com/espressif/esp-idf/tr ... e/littlefs – it should help.

Hello, Yes you can enable flash encryption for single partition by adding encrypted flag for respective partition in partition table.
Please refer this for more details: https://docs.espressif.com/projects/esp ... ition-flag

Hello @akolodner25, the memory allocated by the function 'esp_vfs_fat_register' is utilized to store the FAT context, which serves as essential metadata required for the file system. This is the minimum memory requirement for any scenario.

The example at https://github.com/espressif/esp-idf/tree/master/examples/storage/sd_card/sdmmc shows you how to set SDIO the pins. Also on ESP32-S3, any available I/Os which is not used for other purposes can be used for SDMMC peripheral. The driver will use the GPIO matrix to route the I/Os to the ...

Well, I did not get your exact question, can you please explain it again?
If you want to use 16GB eMMC for storing data along with 1GB external RAM then it’s possible.
But if you want to use 16GB eMMC as external RAM then it’s not possible.
