Weird Gateware version mismatch

1

Hi,

I’m trying to use SdrAngel w/ LimeSDR.
I’ve upgraded the FWs w/ LimeUtil.

However, I see in the log message that a version discrepancy is detected:

[INFO] Make connection: ‘LimeSDR-USB [USB 3.0] 90726074D2515’
[WARNING] Gateware version mismatch!

Expected gateware version 2, revision 18
But found version 2, revision 20

Follow the FW and FPGA upgrade instructions:
http://wiki.myriadrf.org/Lime_Suite#Flashing_images
Or run update on the command line: LimeUtil --update

[INFO] Reference clock 30.72 MHz
[INFO] Device name: LimeSDR-USB
[INFO] Reference: 30.72 MHz
[INFO] LMS7002M calibration values caching Disable
Segmentation fault: 11

but the LimeUtil fails to find any other upgrade.

$ LimeUtil --update
Connected to [LimeSDR-USB [USB 3.0] 90726074D2515]
Existing firmware is same as update (4)
Existing gateware is same as update (2.20)
Firmware and Gateware update is not required.

Programming update complete!

What’s wrong?
What SW component is actually expecting the 2.18 version here?

Thanks,
Manu.

The expected version is coming from LimeSuite library. Best guess sdrangel is linked to old library version.

My understanding is that SDRangel is not linked against any Lime-specific library, as it is supposed to use SoapySDR to access a SoapySDR compliant device, so I would think there is no dependency between Lime & SDRangel (but the SoapySDR library) . I may be wrong.
I used the very last library version from Git to build the Soapy wrapper for LimeSDR.

Would there be a VM image with pre-installed SDR software ready-to-use with LimeSDR?
I spent (hum, lost) the whole day trying to make it work under both macOS then Linux with no luck.

Thanks.

@elot - Emmanuel,

For the --Update it’s likely that an older version of LimeSuite is present and not updated to the latest LimeSuite. Try doing that and then do another update to see if this happens again…

Hi @martywittrock,

I’m using LimeUtil rebuilt yesterday from limesuite 19.01.0.
Is there a newer version?

Thanks.

@eblot - Emmanuel,

Appears you have the latest…Strange issue, normally this doesn’t happen with the latest version of gateware and LimeSuite - it knows it has to recognize the latest and doesn’t report any errors. We’re blazing a new trail here…

This issue looks similar:

I had not time to investigate it yet.
