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