ADRV9364/PlutoSDR

Prepare firmware

Build the firmware follwing the instructions in the Build firmware section.

For PlutoSDR, you can download prebuilt firmware files from https://github.com/seanstone/adrv-fw/releases/tag/201907, and put the files underplutosdr-fw/build/pluto/images/. You can then flash them via the upload target like:

$ make upload

Hardware setup (for ADRV9364)

1. Insert SD card
2. Connect Power, USB, Ethernet
3. Switch on power

Login via serial port (for ADRV9364)

1. Connect USB-UART such that the red LED is on.
2. Login via serial terminal. For example:

install picocom

# apt-get install picocom

and

$ picocom -b 115200 /dev/ttyUSB0

account/password: root/analog

Network initial configuration (for ADRV9364)

The IP address for the host and the device need to be set. For example,

(adrv9364) # fw_setenv ipaddr_eth 192.168.1.1
(adrv9364) # fw_setenv ipaddr_host 192.168.1.100
(adrv9364) # reboot

You can adjust the IP address configuration for different devices.

Login via network (for ADRV9364/PlutoSDR)

Once the network is configured, you can login via ssh:

• ADRV9364

$ ssh [email protected]

or

$ ssh [email protected]

• PlutoSDR

$ ssh [email protected]

or

$ ssh [email protected]

Password: analog

Applications (for ADRV9364/PlutoSDR)

retrogram-plutosdr

Console based spectrum analyzer.

Example usage:

(adrv9364) # retrogram-plutosdr --rate 61e6 --bw 56e6 --gain 73 --freq 935e6 --step 5e6

GNURadio

Installation

1. Install GNURadio

# apt-get install gnuradio

2. Install GNURadio blocks for IIO

# apt-get install libiio-dev libad9361-dev gr-iio

Stream IQ from host

(no module specified) -> Industrial IO -> PlutoSDR Source/Sink

• Buffer size: Size of the internal buffer in samples. The IIO blocks will only input/output one buffer of samples at a time
• Device URI: 192.168.1.1
• RF Bandwidth(MHz): Configures TX/RX analog filters
• Sample Rate(MSPS): Frequency at which the hardware will input/output samples

For more information, see https://wiki.analog.com/resources/tools-software/linux-software/gnuradio

Example RX flowgraph: rx.grc

Running the flowgraph on the device

1. Disable GUI blocks and adjust the top block:

• Set Generate Options to "to No GUI.
• Set Run Options to Run to Completion.

2. Generate the flowgraph and copy the generated python script to the device by scp.

$ scp top_block.py [email protected]:/root/

3. Log in to the device and run the python script on the device.

(adrv9364) # ./top_block.py

See pluto_tx_onboard.grc for example.

GQRX

Host-based spectrum analyzer.

Installation

Follow steps descibed here

1. Add PPAs

# add-apt-repository -y ppa:bladerf/bladerf
# add-apt-repository -y ppa:myriadrf/drivers
# add-apt-repository -y ppa:myriadrf/gnuradio
# add-apt-repository -y ppa:gqrx/gqrx-sdr
# apt-get update

2. Install GQRX

# sudo apt-get install gqrx-sdr

Usage

Set device options:

Build firmware

1. Install requied system packages

# apt-get install build-essential libncurses-dev device-tree-compiler libssl-dev dfu-util

2. Install Xilinx Vivado HLx Editions (2018.3)

• Download from https://www.xilinx.com/support/download.html
• Install to /opt/Xilinx/

3. Init repository from https://github.com/seanstone/adrv-fw

$ git clone https://github.com/seanstone/adrv-fw
$ cd adrv-fw
$ git submodule init
$ git submodule update

4. Apply necessary patches

$ make patch
$ make patch-hdl

5. Choose target to build:

• Build for ADRV9364

  $ make TARGET=adrv9364

• Build for PlutoSDR

$ make TARGET=pluto

• Adding a file to the firmware root filesystem: Put the file in targets/platform/rootfs_overlay in the fimrware source and rebuild the firmware

Flash firmware

For PlutoSDR, there are two interfaces to flash the firmware.

MSD interface

Flash the firmware file using the upload target. This will copy the firmware file to the PlutoSDR MSD(Mass Strorage Device), and start flashing once the device is ejected:

$ make upload

The MSD interface requires a working Linux system with a properly set up MSD gadget. If the MSD interface is working, you can see the MSD device on the host computer file manager when you plug it in.

DFU interface

The DFU is a low-level interface tht can be used to recover the firmware if the Linux system fails to boot up.

Reference: https://wiki.analog.com/university/tools/pluto/users/firmware

1. Enter the DFU mode by holding the hidden button using a pin while powering on (before plugging the USB cable).

2. Flash the DFU firmware by the dfu-all target:

$ make dfu-all
