Because we tend to change all sorts of stuff under the hood between releases. We try to keep things sane by using a FPGA "compatibility number", and use that compatibility number to ensure you're using compatible host code and FPGA images. > > 2.

You can do whatever you want to the FPGA image, we're just saying you should start with corresponding FPGA and UHD host code versions. --n > > Thank you in advance. > > Nemanja > > > _______________________________________________ > Discuss-gnuradio mailing list > Discuss-gnuradio@gnu.org > https://lists.gnu.org/mailman/listinfo/discuss-gnuradio _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
