i am also getting this error āMCU error 4ā
i have been using my limesdr-mini for over a year with no problems with this laptop and its beefy powersupply.
i only just now started to get that error after i recently upgraded limesuite to 19.01 as per the readme and also installed pothos core per readme.
i then updated my lime-mini with āLimeSuite --updateā and it updated the firmware successfully.
i now am getting this mcu error 4.
grrrr
Just throwing it out there, Iām running into this problem too with osmo-trx-lms and srsenb and even the associated example tools. Running LS 19.01 and Gateway Firmware 1.29 on a LimeSDR Mini.
I am having this exact same issue. I got srsENB to work once yesterday and then never again. I donāt specifically recall this error when it was working, but I have it now. Itās very frustrating. Any update on this since the end of April?
To determine if you board is OK, check if you can tune the same frequency using LimeSuiteGUI:
Connect to your board
Press āDefaultā button
In SXT tab set frequency and press āCalculateā (there should be no error messages).
(optionally) check if Tx calibration works at that frequency by using āCalibrate TXā button in āCalibrationsā tab
The error in the first post may appear because Tx calibration is run before setting Tx frequency.
Iām a bit late to the party here but seeing similar issues. I tried the steps above with my LimeSDR-Mini and get āERROR: Tx Calibration: MCU error 4 (SXT tune failed)ā when I click on āCailbrate Txā. Even when running the SimpleSiggen.py script I get the same message on the command line. Is there a way to troubleshoot this? Iām using an external powered USB3 hub so I donāt think low power is the issue hereā¦
