Hi Rurik I have been mostly using the SKA mlib branch until now. When I saw the problem of compiling ROACH2 and ASIAA ADC, I tried to switch to SMA mlib to see if the problem was there as well (my assumption was that since you guys are using the ASIAA ADC actively, you must not have this issue). And indeed while it solved the MMCM clock issue, the fi dependence on Fixed-Point toolbox is a show-stopper there. So I might spend some time cherry-picking the fi dependency out of the SMA branch. I'll let you know the success of this effort.
