Yes, seems like UrJTAG does not detect my scan chain well.
Can somebody please tell me how do we configure scan chain parts ?
I have a OpenOCD configuration that works fine, so I want to do
something similar for UrJTAG. Is this possible or only autodection is
an option? If so, how do we lounch correct autodetect procedure ?
Here is an output of what I have now :

Virtualization is moving to the mainstream and overtaking non-virtualized
environment for deploying applications. Does it make network security
easier or more difficult to achieve? Read this whitepaper to separate the
two and get a better understanding.
