As other people in this list, i face issues with calibration.
I use a limeSDR board, v1.4s, and the LimeSuite, compiled from latest git master, on Ubuntu
So, I see in the source tree: mcu_program, nevertheless no documentation, even a short readme
Looking into this source tree, it seems it tests the calibration, that may be done inside the on board MCU.
I compile with cmake, copy the files it needs ( rxtest.ini, calibrationsLMS7_MCU.hex)
- remane RxTest.ini as rxtest.ini (looking into the source code)
Then I run
$ sudo ./MCU_TestBench
[INFO] LMS7002M cache /home/laurent/.limesuite/LMS7002M_cache_values.db
[INFO] Estimated reference clock 30.7195 MHz
[INFO] Selected reference clock 30.720 MHz
Running tests with LimeSDR-USB FW:3 HW:4
MCU programming : 16384/16384
MCU Programming finished, 926 ms
MCU calibration FAILED : 0x72
F: 1000 MHz, DCI: 0 DCQ: 0 GI:2047 GQ:2047 PH: 0 - FAIL | 100 ms
So, test fails, great but WHAT does IT means ?
Thanks in advance
