Code Generating for Usrp Receiver Block for Raspberry Pi

Hi,

When generating embedded code to run on raspberry pi 2, I get the following build error:

./libmwusrp_uhd_capi.lib: error adding symbols: File format not recognized
collect2: ld returned 1 exit status

The simulink model includes only Sdru Receiver block and a spectrum analyzer.

The lib file was installed with hardware support package. Any ideas to solve this problem?

The whole error message is as follows:

The call to realtime_make_rtw_hook, during the after_make hook generated the following error:

The libmwusrp_uhd_capi.lib library is compiled for a desktop Linux distribution. As a result, you cannot link it to another executable compiled for a Raspberry Pi 2. As of R2015a release, USRP support package can be used on Windows, Linux, and Mac OS X desktop configuration. Regards, Ethem

Hi Ethem I have a similar problem, I don't really get what you mean on your answer. I want to run my model on a RPi which has connected a B200 with UHD drivers working on it. PLease let me know if that is possible.

USRP support package does not support Raspberry Pi targeting. libmwusrp_uhd_capi.lib is a library that is used to make UHD library accessible to MATLAB. That library is only provided for Windows, Mac OS and Linux (desktop) but not for Raspberry Pi.
