Caliberation/AGC Issue Help

Post by nipunamr » Mon Sep 17, 2018 9:09 am

It seems my bladeRF (x115) AGC is not working properly. I tried to run it in Matlab (bladeRF_rx_gui) and I get the following warning.

>> bladeRF_rx_gui
Cannot enable AGC. AGC DC LUT file is missing, run `cal table agc rx' in bladeRF-cli.

when I run the version command from "bladeRF-cli program" I get the following,

C:\>bladeRF-cli -i
bladeRF> version

bladeRF-cli version: 1.6.1
libbladeRF version: 2.0.2

Firmware version: 2.2.0-git-3d38fac2
FPGA version: 0.7.3

bladeRF>

I tried to run the "cal table agc rx" and I get the following errors.

bladeRF> cal table agc rx

Then I used the "print" command to print everything, and I get the following and says "AGC" is disabled

bladeRF> print

I have attached the Matlab GUI screenshot while running. If I tried to change the AGC dropdown to "AUTO" from "MANUAL" I keep on getting the same Matlab warning (Cannot enable AGC. AGC DC LUT file is missing, run `cal table agc rx' in bladeRF-cli.)
and it goes back to "MANUAL"


What's happening here? Is there a way to enable the AGC?

Can you try running the "cal table agc rx" command in the CLI with verbose output?

Code: Select all

bladeRF-cli -v verbose -e "cal table agc rx"

When I ran the command, it was outputting so much information. So, I did a Ctlr+C to stop the program. It eventually, stopped an gives me an error. Here's some output. I'll try to copy the whole output to a file, I haven't figured out yet. Do you want the full output?

No, that is okay. This appears to be a bug as we are able to reproduce it on our end. Feel free to track the progress on the issue tracker.

Thanks, Hopefully it will get fixed quickly. I will work on my time stamping problem in the meantime.

Hello

I've run into this same issue. What is the fix now? I've just installed the latest bladeRF on my Windows computer and updated the firmware as instructed.

What is the next step to add this fix? Sorry...I'm not the world's expert in GIT hub or software.

Thanks

You said you updated the firmware -- do you mean the FX3 firmware, the FPGA, or both? When you open the bladeRF-cli, what is the result of the 'version' command?
