SDWireC is a yet another implementation of SDWire of Tizen. In our design we used USB-C interface to interact with the host device or in other words Test Server(TS).
In sdwirec-hw folder, you can find the KiCAD project files of SDWireC, hardware design mostly based on Tizen but we changed some of the components since they are out of stock today.
In sdwirec-sw folder, you will find the clone of https://git.tizen.org/cgit/tools/testlab/sd-mux which has the software that you need to interact with SDWireC.
