Thank you for the detailed feedback. That is very helpful. Looks like I have some homework to do...</div>

For the Zynq platform, the only bidirectional bulk data interface that<br>
is supported out-of-the-box is the Ethernet port. There's also an<br>
NFSv2 client (look for librtemsNfs.h) if your code is tightly coupled<br>
to filesystem-like interfaces... and you're willing to deal with the<br>
network security issues inherent to NFSv2.<br>
<br>
For a one-way interface from your development environment to the<br>
application, you can also package some program data with your<br>
application using the UnTar_Xz* family of support functions and<br>
rtems-bin2c.<br>
<br>
Depending on how early you are in the development cycle, it may be<br>
worthwhile to take a look at nexus-devices.h to get a better idea of<br>
which BSP's support which features. The Other Leading Brand (Intel<br>
nee Altera Cyclone V) has better RTEMS support right now.<br>
