Storage

The Intel® Joule™ platform offers multiple solutions for data retention: eMMC, SD Card, and SDIO. Each storage type is intended for a specific use but offers the developer the flexibility to choose between them.
eMMC*
The module contains an embedded MultiMedia Card (eMMC) with ether 8GB or 16GB of storage capacity. See the System on Module Overview for module configurations.
A 5.1 controller handles eMMC* Protocol at transmission, packing data, adding cyclic redundancy check (CRC), start/end bit, and checking for transaction format correctness.
The eMMC* 5.1 controller specifications and datasheet can be found online at: http://arasan.com/products/emmc51/emmc51-device.html
SD Card 3.0
Out of the box,the Intel® Joule™ developer kit has a removable 16 GB Micro SD Card v3.01 whose primary function is a removable storage device.
 
 It uses an Arasan SD3 controller that handles SD Protocol at transmission, packing data, adding cyclic redundancy check (CRC), start/end bit, and checking for transaction format correctness.
 
 This controller can also support SDIO (Wi-Fi + BT) devices instead of an SD (storage) card.
The Arasan SD3 controller datasheet can be found online at: https://arasan.com/wp-content/media/SD3-0-SDIO3-0-eMMC5-0-Host-Controller-_Rev-1.0-2.pdf
To format your card, locate the home for your SD card connector by the command:
$ df
It should produce something similar to:

 /
Identify the path to your SD card.
 
Use the
mkdosfs
command to format the card:
sudo mkdosfs –F 32 –v /path/to/sd/card
where:
               
 -F flag is for the Fat32 file system
               
 -v flag is for verbose
S
DIO
The SDIO is intended to provide storage for an external Wi-Fi* device.
 
 It uses an SDIO 3.0 controller that handles SDIO Protocol at transmission, packing data, adding redundancy check (CRC), start/end bit, and checking for transaction format correctness.
