1. Failed to Mount MicroSD Card​

  1. Ensure the MicroSD card is of reliable quality.
    We recommend using Class 10 or higher cards to guarantee sufficient read/write performance and stability.
    We have verified that cards from SanDisk and SmartQuickly work properly.
    Since there are many brands and models on the market, it is impossible to test them all, but the above brands are recommended.

  2. Verify that the MicroSD card is properly formatted.
    Supported file systems include FAT32 and ext4.
    If you are using the card for the first time or have recently changed the system, please reformat the card to ensure compatibility.
