Description

Demonstrate configuring PicoSDR and launching demo application that utilizes Perseus carrier board for RX/TX.

Set up

Before you can access the testbed, you need to ​make a reservation and get it approved by the reservation service. After receiving the reservation's confirmation (approval) email, load the ubuntu-14-04-64bit-sdr.ndz on the node. Once loading is finished turn the node on. For this example we'll use node1-12 which is a ​PicoSDR. 

ssh username@grid.orbit-lab.org
omf load -i ubuntu-14-04-64bit-sdr.ndz -t node1-12
omf tell -a on -t node1-12

Once the node1-12 is up, ssh into the node1-12 (which is the PicoSDR's embedded PC) and configure the eth2 interface 

ifconfig eth2 192.168.0.100 up

Verify connection to Perseus carrier board: 

ping 192.168.0.101

Use a command line interface to load the Perseus carrier board with an FPGA bitsteam - for this example we'll use the "/opt/Nutaq/ADP6/ADP_MicroTCA/sdk/fpga/bin/GNURadio_Radio420_PCIe_sx315.bit": 

cd /opt/Nutaq/ADP6/ADP_MicroTCA/sdk/bin
python adp_cli.py
connect 192.168.0.101
fpgaflash 1 ‘/opt/Nutaq/ADP6/ADP_MicroTCA/sdk/fpga/bin/GNURadio_Radio420_PCIe_sx315.bit’
reboot

The PicoSDR2x2E block diagram shown below describes how all the peripherals interconnect with the embedded CPU (Quad-Core CPU) and FPGA (Virtex-6).

Since GNURadio_Radio420_PCIe_sx315.bit uses the PCI Express Bus to interface between the embedded PC and carrier board's FPGA (Virtex-6), install the PCI Express Driver on the embedded PC: 

cd /opt/Nutaq/ADP6/ADP_MicroTCA/sdk/PCIe/driver/host
sh make-modules.sh
sh setonpc.sh

If the embedded PC is restarted then setonpc.sh must be excuted again

Launch demo scripts

Now the system is ready to build and run the demo application. Navigate to the demo project directory: 

cd /opt/Nutaq/ADP6/ADP_MicroTCA/sdk/examples/perseus6010_radio420x_rtdex_record_playback/host/prj_linux
sh build_demo.sh

Run the demo file: 

sh Launch_radio420x_rtdex_record_playback.sh

Choose the appropriate option to run. 

Choose the data path:
 - Type '0' to execute passthrough (data looped from ADC to DAC in the FPGA)
 - Type '1' to output DDS signal (generated in the FPGA)
 - Type '2' to execute a data record
 - Type '3' to execute a data playback
 - Type '4' to stream data to the host
 - Type '5' to stream data from the host

From here you can use a nearby USRP node on the grid for signal generation / verification. Please refer to ​this tutorial for instruction on using USRPs.
