TX DC calibration not working

Correct about that function, but currently GUI uses the API function LMS_Calibrate() which always passes false to the useExtLoopback parameter.

case LMS_CLOCK_CGEN:
{
    int ret =0;
    lms->Modify_SPI_Reg_bits(LMS7param(MAC),1);
    if (freq <= 0)
    {
        ret = lms->TuneVCO(lime::LMS7002M::VCO_CGEN);
    }
    else
    {
        ret = lms->SetInterfaceFrequency(freq, lms->Get_SPI_Reg_bits(LMS7param(HBI_OVR_TXTSP)), lms->Get_SPI_Reg_bits(LMS7param(HBD_OVR_RXTSP)));
    }
    if (ret != 0)
        return -1;
    return SetFPGAInterfaceFreq();
}

    lime::ReportError(ENOTSUP, "Setting TSP clocks is not supported.");
    return -1;
