eMMC Support

Introduction

This plugin reads the sysfs attributes corresponding to eMMC devices. It uses the kernel MMC API for flashing devices.

Protocol

eMMC devices support the org.jedec.mmc protocol.

GUID Generation

These devices use the following instance values:

  • EMMC\%NAME%
  • EMMC\%MANFID%&%OEMID%
  • EMMC\%MANFID%&%OEMID%&%NAME%

Update Behavior

The firmware is deployed when the device is in normal runtime mode, but it is only activated when the device is rebooted.

Vendor ID Security

The vendor ID is set from the EMMC vendor, for example set to EMMC:{$manfid}

External interface access

This plugin requires ioctl MMC_IOC_CMD and MMC_IOC_MULTI_CMD access.
