Running MCU Calibration via LimeSuite

Hi @IgnasJ,
Now I am able to set the LPF Bandwidth successfully . I am using LMS_Calibrate() to do RX chain calibration and it gives me the following error
Rx calibration: MCU error 5 (Loopback signal weak: not connected/insufficient gain?) .
I am not using LMS_Init as this is a custom board . I have the following questions —

  1. Do I have to enable some components before using LMS_Calibrate ?
