Hello Martin, Thanks for your reply and apologies for my late reply.
I now have the MPM daemon & MPC server up & running by executing the file ‘uhd/mpm/python/usrp_hwd.py’. There were a few issues, one of which was successfully building & installing the mprpc python module. I “WOULD” like to start by enabling the simulator. I have written some C++ code to do this. I see the following o/p. Q. Would you be able to help with the exception that I am seeing ? Many Thanks, -Phil ==================== Device address: type=sim 1st find() Number of addresses found = 1 Device 0: Device address: type=mpm,addr=127.0.0.1,mgmt_addr=127.0.0.1 Creating a USRP device !!!

Before we go down the rabbit hole of debugging, why are you doing this?

The following MPM build sequence creates the file ‘libusrp-periphs.so.4.8.0’ in the directory ‘/usr/lib’. In the same directory ‘/usr/lib’, the symlink ‘libusrp-periphs.so’ references ‘libusrp-periphs.so.4.8.0’. cd uhd/mpm mkdir build cd build cmake ../ sudo make -j2 install ==================================== I also see the shared object file ‘libpyusrp_periphs.so‘ located in the sub-directory ‘/usr/lib/python3.10/site-packages/usrp_mpm’. ==================================== To start the MPM daemon and RPC server, I am executing the python file ‘uhd/mpm/python/usrp_hwd.py’ using the following command. python3 ./usrp_hwd.py Q. Is this how I should be starting the MPM daemon and RPC server ? Note that this file does the following import. import usrp_mpm.libpyusrp_periphs as lib ==================================== This is the output I see on the command-line (see error at the end).

It SHOULD therefore be found when using the following import statement. import usrp_mpm.libpyusrp_periphs as lib Q. Any idea why this is NOT working for me ? _______________________________________________ USRP-users mailing list -- usrp-users@lists.ettus.com<mailto:usrp-users@lists.ettus.com> To unsubscribe send an email to usrp-users-le...@lists.ettus.com<mailto:usrp-users-le...@lists.ettus.com>
