SDWire

SDWire is a small board with two features:

• SD card reader
• SD card MUX

SDWire allows to flash SD card connected to the DUT (Device Under Test), without physical contact with the device. There is only one micro USB socket for connecting to host PC. Both USB mass storage and MUX control are served through the same USB connection.

The PCB board is designed in such a way that it fits into micro SD card slots. Thanks to this, there is no need for special cables with a micro SD adapter, like in the muxPi product.

SD-MUX has dedicated software which is a simple tool meant to control the hardware. Source code of the tool is published on tizen git server. This is simple to use, command-line utility software written in C and based on open-source libFTDI library.
