== Nutaq - PicoSDR start-up and configuration ==

[[TOC(Tutorials/k0SDR*)]]

=== 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 [https://www.orbit-lab.org/schedule make a reservation] and get it approved by the  [wiki:Software/Scheduler 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 [http://www.nutaq.com/products/picosdr 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
}}}

Since ''GNURadio_Radio420_PCIe_sx315.bit'' uses the PCI Express Bus to interface between the embedded PC (Quad-Core CPU) 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 [http://www.orbit-lab.org/wiki/Tutorials/k0SDR/Tutorial00#WorkingwithUSRP2-UniversalSoftwareRadioPeripheral this tutorial] for instruction on using USRPs.
