LimeMini PowerON sequence

EnthuMan · 16 May 2019 10:37

Hello,
We wish to know what happens when the LimeMini first powers ON. Is the calibration data (precalibrated Tx, Rx chain calibration, filter calibration) retrieved from the on-board flash memories and written to the LMS?
Or does the MCU inside the LMS do it on power up, as a background process.
Regards,

Hi @EnthuMan,

All the initialization is done from PC side on LimeSDR boards. No MCU or Flash memory involved. This is initialization of LimeSDR-USB board:

github.com

myriadrf/LimeSuite/blob/master/src/API/lms7_device.cpp#L1326


            tx = true; //assume that Tx PLL used for TX and RX
   }
   return lms->GetFrequencySX(tx) - offset;
}


LMS7_Device::Range LMS7_Device::GetFrequencyRange(bool tx) const
{
    return Range(100e3, 3.8e9);
}


int LMS7_Device::Init()
{
    struct regVal
    {
        uint16_t adr;
        uint16_t val;
    };


    const std::vector<regVal> initVals = {
        {0x0022, 0x0FFF}, {0x0023, 0x5550}, {0x002B, 0x0038}, {0x002C, 0x0000},
        {0x002D, 0x0641}, {0x0086, 0x4101}, {0x0087, 0x5555}, {0x0088, 0x0525},
