Re: Loading to the FPGA

Copying/pasting revisions like that seems prone to errors. There's probably some path or file name issue happening there. Did you follow the guide on our Wiki on how to create a custom revision?

Re: Loading to the FPGA

I believe the problem you are having is that you are running the nios2_command_shell.sh instead of sourcing it. The "source" command will execute the nios2_command_shell within the current shell session, allowing it to setup the environment so the build_bladerf.sh script can find all the Quartus bin...

Re: Building bladeRF on Arch

I have the same issue on Arch, gcc v8.1.0-1. We may already have a fix for this in our dev repo that we can push out soon. Please create an issue on GitHub so we can track it.

Thanks for reporting!

Re: abnormal calibration with kalibrate-bladerf

Kalibrate is terrible -- we don't recommend it. Instead, we recommend grabbing a decent GPS disciplined oscillator like the one from Leo Bodnar or a decent 10 MHz reference. Take a look at our blog post about VCTCXO taming with a GPSDO. Ideally you want a GPSDO or reference that will output a 10 MHz...

Re: GPIO: Set output pin by sample count

Is rx_sample_fifo.wclock equivalent to lms_rx_clock_out in the diagram shown in the tutorial [https://github.com/Nuand/bladeRF/wiki/F ... chitecture]? Yes. My sample rate is going to be 20M. So if I'm reading the diagram correctly, the lms_rx_clock_out will be 40M (or 2x sample rate). Yes. So, I th...

Re: External clock input of 10MHz

We have a factory calibration lookup page: http://www.nuand.com/calibration.php

If nothing shows up for your serial number, please send us an e-mail with your serial number and I'll see if we can get it from the factory.

Re: GPIO: Set output pin by sample count

Yes, you can do this. I would suggest rising_edge( rx_sample_fifo.wclock ), then count the number of cycles that rx_sample_fifo.wreq is '1' to get your sample count. Also consider how you want to clear the counter. One suggestion is to do this when rx_enable is '0'.
