'''SUMMARY '''<br><br />
The MMC (MultiMediaCard) / SD (secure digital) / SDIO (secure digital input/output) subsystem implements a standard Linux<sup>&reg;</sup> host driver to interface with MMC / SD memory cards or SDIO cards.<br />
<br />
== Framework purpose ==<br />
The purpose of this article is to introduce the MMC Linux<sup>&reg;</sup> subsystem (MMC / SD) by: <br />
* providing general information<br />
* describing the main components/stakeholders<br />
<br />
The SDIO is addressed in the [[WLAN_overview|WLAN overview]].<br />
<br />
==System overview==<br />
<br />
[[File:MMC_overview.png|center|link=]]<br />
<br />
===Component description===<br />
* User space applications handle '''file I/O''' management to view the card memory as a disk, whereas programs that perform '''raw I/O''' accesses see the memory as a block device<ref>https://en.wikipedia.org/wiki/Device_file#Block_devices</ref>.<br />
<br />
* '''VFS''' (Kernel space)<br />
Virtual File System. Please refer to the VFS documentation <ref>{{CodeSource | Linux kernel | Documentation/filesystems/vfs.txt | VFS}} </ref>.<br />
<br />
* '''MMC core/SD/MMC/SDIO''' (Kernel space)<br />
The '''MMC core''' ensures compliance with MultiMediaCard ('''MMC''')<ref>[https://www.jedec.org/standards-documents/technology-focus-areas/flash-memory-ssds-ufs-emmc/e-mmc MultiMediaCard], embedded MultiMediaCard specification</ref> / secure digital ('''SD''')<ref>[https://www.sdcard.org/ Secure Digital], secure digital specification</ref> / secure digital input/output ('''SDIO''')<ref>[https://www.sdcard.org/ Secure Digital Input Output], Secure Digital Input Output specification</ref>.<br />
<br />
* '''SDMMC driver''' (Kernel space) / '''SDMMC''' (hardware) <br />
The '''SDMMC driver''' handles:<br />
* the registers, the clock, the interrupt and the IDMA control.<br />
* the communications over the bus based on command/response and data transfers.<br />
Please refer to the [[SDMMC internal peripheral]].<br />
<br />
===API description===<br />
The MMC core handles the file system read/write calls.<br />
<br />
==Configuration ==<br />
===Kernel configuration===<br />
The MMC framework is activated by default in ST deliveries. If a specific configuration is needed, this section indicates how the MMC framework can be activated/inactivated in the kernel.<br />
<br />
The MMC framework can be activated in the kernel configuration via Linux<sup>&reg;</sup> Menuconfig tool: [[Menuconfig or how to configure kernel]]<br />
<br />
<pre><br />
[*] Device Drivers<br />
[*] MMC/SD/SDIO card support<br />
<*> HW reset support for eMMC<br />
<*> Simple HW reset support for MMC<br />
<*> MMC block device driver<br />
(16) Number of minors per block device<br />
...<br />
<*> ARM AMBA Multimedia Card Interface support<br />
[*] STMicroelectronics STM32 SDMMC Controller<br />
</pre><br />
<br />
===Device tree configuration===<br />
DT configuration can be done thanks to [[STM32CubeMX]].<br />
<br />
Please refer to the [[SDMMC_device_tree_configuration| SDMMC device tree configuration]].<br />
<br />
==How to use the framework==<br />
A file system, which handles read/write/erase operations, can be used with the MMC framework. Please refer to the [[How to support EXT4 through MMC|EXT4 support through MMC]].<br />
<br />
<br />
==How to trace and debug the framework==<br />
<br />
===How to monitor===<br />
The sysfs interface provides detailed information on each mmc device:<br />
<br />
<pre><br />
root:~# cat /sys/kernel/debug/mmc0/ios<br />
clock: 50000000 Hz<br />
vdd: 21 (3.3 ~ 3.4 V)<br />
bus mode: 2 (push-pull)<br />
chip select: 0 (don't care)<br />
power mode: 2 (on)<br />
bus width: 2 (4 bits)<br />
timing spec: 2 (sd high-speed)<br />
signal voltage: 0 (3.30 V)<br />
driver type: 0 (driver type B)<br />
</pre><br />
<br />
===How to trace===<br />
For details on dynamic trace usage, refer to [[How to use the kernel dynamic debug]].<br />
<br />
root:~# echo "file drivers/mmc/* +p" > /sys/kernel/debug/dynamic_debug/control<br />
<br />
==Source code location==<br />
The MMC framework is available {{CodeSource | Linux kernel | drivers/mmc | here}}.<br />
<br />
==References==<br />
Please refer to the following links for a full description of the MMC framework:<br />
