    All SD Cards compliant to the SD Card Association physical layer specification are required to be backwards compatible to the data transfer modes supported by AM335x. Therefore, I would not expect any hardware compatibility issue. You will need to check your SD Card software driver to see if it supports these cards.

    Hi Akshay,

    AM3356 doesn't have special MMC requirement in software. Whatever MMC functions supported in kernel v4.14.67 would work on AM3356 too.

    Please note that - as stated in the AM335x Errata Section 3.1.5, only Standard (STD) and High Speed (HS) modes are supported on MMC0/1/2 interfaces. SDR12, SDR25 and SDR50 modes are not supported.
