From the project
SD CARD and eMMC Device Multiplexer with Infrared Remote Controller
The SDCDMUX provides a convenient and quick change of a SW image of a device that has an SD Card interface from a remote.
When I am developing by booting from an SD memory card on a device such as the Raspberry Pi, it is not easy to rewrite the SD card image and replace it by hand. Remove the SD card, insert it into the host PC, and take a dozen minutes rewriting the SW image, after that, return the SD card to the device and turn on the power... But, This tool can change the image of the eMMC directly from the host PC, and the device can be booted as an SD card with the new image.
