AM2634-Q1: Request for AM2634 to eMMC Interface Details & Design Guidance

Part Number: AM2634-Q1
Other Parts Discussed in Thread: AM2634

Hello,

I am working on a design using the AM2634 MCU and would like to interface it with an eMMC memory device (data storage/logging). I have reviewed the available documentation but could not find detailed guidance on the recommended interface configuration for eMMC.

Could you please help with the following information:

  1. Supported eMMC interface mode on AM2634 (e.g., legacy MMC, HS200/HS400, 1‑bit/4‑bit/8‑bit modes).
  2. eMMC used only for data storage/logging.
  3. Which memory part# I have to use? 
  4. Pin mapping / peripheral assignment for the MMC/eMMC interface on AM2634.
  5. Reference designs or hardware design guidelines for connecting AM2634 to eMMC.
  6. Any available SDK/driver examples for MMC/eMMC on AM263x devices.

Any pointers to documentation or example projects would be greatly appreciated.

Thank you!

    The MMC on AM263 supports MMC4.3 specification. I am not able to find eMMC 4.3 standard. 

    The AM263x MCU+ SDK (latest version 11.00.00.19) provides comprehensive support for eMMC storage, including drivers, file system integration, and bootloader functionality to boot applications directly from eMMC.

    Key eMMC Features in AM263x SDK:
    • Drivers & File System: Includes low-level drivers (LLD) for eMMC and often integrates libraries like FatFs for file system management.
    • Bootloading: Supports SBL (secondary bootloader) to load applications from eMMC.
    • Examples: The SDK provides examples for accessing and using non-volatile storage like eMMC.

    I am not sure if all the eMMC features are supported by the SDK.
