Compatibility of High-Capacity microSD Cards with STM32MP157F-DK2

Dear ST Team,

I'm considering purchasing a microSD card for the STM32MP157F-DK2 development board, but I want to ensure compatibility before buying.

The documentation mentions support for SanDisk Class 10 and UHS Speed Class 1 cards but doesn’t specify the maximum supported capacity. I know the board supports SDHC and SDXC standards, so theoretically, it should handle up to 2 TB (per the SDXC specification).

Here are my questions:

  1. Has anyone successfully used a 256 GB microSD card (e.g., SanDisk SDSQUAC-256G-GN6MA Ultra 256GB UHS-I Class 10) with this board?
  2. Are there any practical limitations or known issues when using SDXC cards with capacities above 128 GB?
  3. Does the STM32MP157F-DK2 fully support exFAT, or is additional configuration required?

Any insights or experiences with high-capacity microSD cards on this board would be greatly appreciated.

Thanks in advance!

    I bought this microSD card: https://www.e-shop.gr/sandisk-sdsquac-256g-gn6ma-ultra-256gb-micro-sdxc-a1-u1-uhs-i-class-10-sd-adapter-p-PER.323711 , and it works well.

    There is a small delay of about 15 minutes during the first boot (resize storage), but after that, it works perfectly.

    Best regards,
