Why is there no MMC usage information on A10 SoC uboot?

Environment

  • Intel® Quartus® Prime Pro Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to that SoC EDS v17.0 & 17.1 Bootloader code has not been switched to mainstream uboot code, there is no usage information when you run mmc command in uboot command shell. Currently the information is as below:

    SOCFPGA_ARRIA10 # mmc

    mmc - MMC sub system

    Resolution

    The SoC EDS Bootloader can support the MMC commands. The MMC usage information just likes as below:

    SOCFPGA_ARRIA10 # mmc

    mmc - MMC sub system

    Usage:

    mmc info - display info of the current MMC device

    mmc read addr blk# cnt

    mmc write addr blk# cnt

    mmc erase blk# cnt

    mmc rescan

    mmc part - lists available partition on current mmc device

    mmc dev [dev] [part] - show or set current mmc device [partition]

    mmc list - lists available devices

    mmc setdsr <value> - set DSR register value

    You can run these commands directly.

    The MMC usage information will be added into a future SoC EDS Bootloader version.
