Isn't FTx232 chip an example of interface that provides access to raw GPIO? As a general note - it we would build a list of "wanted features" for OpenOCD I guess SWD would be nr 1 for now. That's why I just don't understand why noone's interested in implementing that... 4\/3!! ------------------------------------------------------------------------------ Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
