I have a 7 tile (4 packages) design that I'm trying to get to boot over XLink but I'm running into an issue.
The system looks like so (link numbers are in parenthesis). The formatting is not working but the QSPI flash is connected to the first XE216 part. Also note the pair of links between the XE216 parts:
XL208 (0)<--->(4) XU216 (0) <---> (0) XE216 (7,4) <===> (0,3) XE216

QSPI Flash
I'm able to xrun the application with no problem which would seem to validate the links and validate the network is routable.
When I attempt to xflash the application I'm met with:
Is this an issue with XFlash not supporting my topology?WARNING: Trying to communicate over XLink0 when it is not connected
Segmentation fault: 11
Here is my XN file for reference. If anyone has a moment to look at this problem I would be grateful!!
