BB60C Intel Atom Functionality

[Labbench1]

Would it be possible to get a recompiled library for operation of the BB60C on Intel Atom chipsets?

Hi Labbench1,

The current releases should run on Intel Atom right now. I should let you know that we have not tested the BB60C on the Atom architecture. It is unlikely that the available Atoms are able to perform the necessary signal processing needed for the BB60C to operate. I suspect most sweeps will be OK and slow, but it will have issues with modes like zero-span, real-time, or demodulation (audio/digital).

If you are able to try it, we would be interested to hear about your results.

Hi Labbench,

Additionally, I do not know what support is like for USB 3.0 on the Atom CPUs and motherboards, so I would not be surprised if you run into issues with this.

Would there be any reason you could think of why it wouldn’t run using Ubuntu 14.04 on the Atom chipsets? Looks like I can follow the build guide and compile the programs okay, and the device is attached without any noticeable errors, but when I run the sample programs I get core dumps.

When I tried Windows it looked as though the device was able to communicate.

Hi Labbench1,

I apologize, I did not realize you were working on a Linux OS. Yes, there is an issue on Linux, the library was compiled naively on a Haswell CPU and now requires a Haswell CPU or newer i-series model CPU to run properly. It was compiled with the -march=native flag, which inserted architecture specific instructions.

We haven’t set aside time to recompile it again for Linux. I’ll see if this could be done sooner than later. In the meantime, you mentioned you have a Windows OS you can run it on?

I apologize for the inconvenience.

Regards,
A.J.

No problem. We’re definitely interested in Linux as our primary development environment. Windows was installed to see if that had any different results.

Thanks for your extremely fast replies!

Of course,

Since you are using the Atom CPUs, it would be good to characterize the behavior on Windows first. Our application uses the API under the hood, so you can get a good idea on how various features work. The API functions similarly on both Windows/Linux, so when I get it recompiled, porting should be easy, if you are able to start development on Windows. Shoot me an email at aj at signalhound dot com and I will email you when I get a new Linux version up. I can’t guarantee any time frame though, maybe in the next couple weeks.

Morning! Just wanted to make sure you got my email outside the forum. Thanks again!

[Andrew]

Hi Labbench1,

Yes I did. I have made a note to notify you when the API has been compiled on Linux and is on the website. I suspect early next week. I’ll make a point to do it on Monday or Tuesday.

Apologize for the wait.

Regards,
A.J.

No problem at all. Just wanted to confirm the email was received.

We really appreciate your help with this!
