I’ve recently taken delivery of a LimeSDR USB board and am trying to get it working, using the directions in Quicktest. I am running on Windows 7 on a laptop with USB2.0 ports.
So far I have installed the device driver and the board successfully enumerates and I can see it in Device Manager under the USB devices as “Myriad-RF LimeSDR-USB”. I have installed LimeSuiteGUI by installing Pothos SDR environment (vc12-x64) and can connect to the LimeSDR board using the Options | Connection settings tab in the GUI, where it comes up as
“LimeSDR-USB [USB 2.0] 9072C02871918”. From connecting I can get the temperature of the board by clicking the “Read Temp” button. So everything seems to be working there.
I have downloaded the “self_test.ini” and “example.ini” files to be able to run the QuickTest, together with the waveform files (onetone, wcdma, LTE_DL_TM31_20MHZ in lms7suite_wfm directory - is there anywhere special this directory should live? Nothing mentioned in the Quicktest doc)
Following the directions in Quicktest I clicked the Open button in LimeSuiteGUI to open a file and selected “self_test.ini” When I hit ok, a dialog box comes up and tells me that it “Failed to load file” and in the log window I get
[10:24:59] ERROR: Write(64 bytes) failed
When I click ok on the dialog box the GUI hangs for several minutes and then writes out another load of the same error message in the log window. I have tried this several times and noticed that one of the two normally green LEDs flashes red during the time the error messages are printed in the log, once for each error message
I was surprised that there is any comms between the PC and board at this stage - I thought that I would have to press the GUI->Chip button before the settings read from the file would attempt to be transferred. Note that I haven’t got that far - the failure to load seems to screw up comms between the PC and LimeSDR to the extent that if I click Read Temp button I get back a value of 0, not around 50C as previously. The only way to restore comms is to unplug the LimeSDR USB and reinsert, then reconnect the GUI
Any idea what I am doing wrong, or have I missed downloading something? Could there be a problem with the format of the “self_test.ini” file? I have updated the gateway and firmware in the LimeSDR to match the versions expected by LimeSuiteGUI
Any help gratefully received
