Problem running Quicktest on LimeSDR USB


#1

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
Thanks

@Zack could you assist, please.

Hi @PaulC,

Test you board using LimeQuickTest and share the log file please.

Hi @Zack
Here are the results of the LimeQuickTest. The test gets into the Loopback test and then just hangs

Paul

Could you test it via USB3?


#7

Hi @Zack
Sorry for the slow reply - I’ve been trying to source a PC with USB3 and cabling so I can run the test as you suggested.

I have connected the board to the USB3 port with a 1m extender cable (USB3 A plug to USB3 A socket)

The first time I tried it, LimeQuickTest app ran ok, but since then I haven’t managed to get it to work; it always fails in the RF Loopback Test.

I have tried it multiple times, sometimes back-to-back with a previous run and other times depowering the LimeSDR-USB board between runs, but it always fails in the TX_1->LNA_W and TX_2->LNA_H tests in the Loopback

Enclosing a sample log file of one of the failing runs
