Decided to update limesuite and see if limesuitecaibrate.py had been fixed because the limeutil --calibrate brakes HF reception … error error error … why for do you error

In the build directory “grep -r mfpmath *” will display a number of files.
Edit each and remove “-mfpmath=both”
The make -j 4 works.
I haven’t checked for a shorter way of removing it from all files or if it’s generated from one file and propagated to the others.
Could try removing it from CMakeLists.txt in the LimeSuite directory on the line and running cmake … again.
CMakeLists.txt: add_definitions(-march=native -mfpmath=both)

P.S:- removing -mfpmath=both from that one line in CMakeLists.txt does the trick.

Rthanks sid …

Was going to see if limeutil – calibrate still brakes HF rx … iv posted a video if it

I don’t see an option to set the sample rate.

LimeUtil --cal --start 3500000 --stop 30000000

Expected gateware version 2, revision 8
But found version 0, revision 0
Follow the FW and FPGA upgrade instructions:

Or run update on the command line: LimeUtil --update

I dont know … it worked a few months ago …
But didnt test the results till recent …

Wonder when/if LimeSuiteCalibrate.py is going to be reinstated … its the only one that actually worked for hf …
