If you configure any board to work in CMOS mode, and it does not, this is expected. If it does work, it just means the combination of AD9361 board, AD9361, connectors, carrier layout and FPGA are barely working. CMOS mode is known to work on platforms without connectors between the AD...

hii all i want to implement MCS with 2 ad9361 devices with the ad9361_do_mcs() function but one of the ad9361 i1 and i1 are not getting proper. i want to know both devices having different sync in pins are both having the same sync in . please help me out with thia rega...
