Hello sir. I'm a relative newbie with rfnoc to build X310 loads so I may have missed something, but if so, I can't find what it is.
After successfully making many HG builds (one 1GbE link, one 10GbE link), I reached a point where I needed higher X310 to host bandwidth so switched to making XG builds for the X310 with two 10GbE links with the following: ./uhd_image_builder.py fft ROMsiggen keep_one_in_n -I ~/rfnoc/src/rfnoc-X310ROMtx/ -d x310 -t X310_RFNOC_XG -m 5 --fill-with-fifos This worked well and I was then able to communicate to the X310 over a 10GbE link on port 0, but when I wanted to make an HG build again with the same HG command used previously, Vivado failed with fatal errors about unassigned physical pins when I used the following: ./uhd_image_builder.py fft ROMsiggen keep_one_in_n -I ~/rfnoc/src/rfnoc-X310ROMtx/ -d x310 -t X310_RFNOC_HG -m 5 --fill-with-fifos I found that when making XG builds, at least one constraints file, including x300.xdc in ~/rfnoc/src/uhd-fpga/usrp3/top/x300 was changed to reassign physical pins on the ethernet links but was not changed back when I later tried to make an HG build again. I was able to work around the problem by restoring the x300 constraints files to their original versions but it would be nice if the build scripts did this automatically. Assuming this is not due to an error on my part, is there any planned update for this? OS: Ubuntu 16.04 SW: Vivado HLS 2015.4 Thanks, John McGinn Cognitive Systems Corp.
