Hi, We are using the reference design for AD9364 along with ZC-706 in Non-OS mode. We changed the AGC mode to MGC mode with rx1_rf_mode=0. When I tried to change the Rx gain with rx1_rf_gain=50 found that the AD9364 chip stops transmitting Power and not allowing further commands. When the chip is used in Linux mode with HDMI Monitor, it is working fine in MGC mode where able to change Rx gain. Please let us know do need to do any modifications for the reference design?

Nothing to do, device is already in 10 state

Ignoring lmt/lpf/digital gains in Single Table mode
