Re: External power supply

Just in case anyone else has trouble and comes across this post, the relevant information is in our bladeRF Accessories Wiki article: https://github.com/Nuand/bladeRF/wiki/bladeRF-Accessories#external-dc-power Unfortunately, the bladeRF has no way of knowing whether it is being powered over the USB ...

Re: How to extract a header file

Oh, yeah it's not in a header file. The timestamp is a run-time value that used for synchronous TX or RX. It can be used to transmit or receive at a specific time, or to simply RX/TX and report back the current time of the data buffer. Some more information about this is in our API: http://www.nuand...

Re: Terrible sensitivity?

The NOAA satellites are at 137 MHz, so I assume you are using the XB-200. There are some additional losses that occur on that board in addition to the bladeRF itself, so you may need an LNA. What is your filterbank set to on the XB-200? The custom path is probably where you want to be, and either us...

Re: [SOLVED] Loading to the FPGA -> operation timed out

My best guess is shipping damage based on the fact that we test these boards for proper operation before they ship. If there's an issue loading the FPGA, the tests would (should!) fail. I am glad that the fix is holding up. Please do let us know if the issue returns as it could be indicative of some...

Re: [SOLVED] Loading to the FPGA -> operation timed out

That is... very interesting. I am not sure why / how L51 could have broken, or how it could have passed our testing prior to shipment, but it does seem somewhat of a peculiar error. I have a note in to check for this in the test code. At any rate, I am glad you were able to track it down to that and...

Re: How to extract a header file

Would you mind providing more information? I'm not quite sure what you are asking. The official hosted FPGA image and libbladeRF support timestamping already, so you could do the demodulation on the host in software or on the bladeRF in the HDL. Demodulating in HDL is of course more accurate, but yo...

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!
