Build Artifacts

• Main targets

  File	Comment
  pluto.frm	Main PlutoSDR firmware file used with the USB Mass Storage Device
  pluto.dfu	Main PlutoSDR firmware file used in DFU mode
  boot.frm	First and Second Stage Bootloader (u-boot + fsbl + uEnv) used with the USB Mass Storage Device
  boot.dfu	First and Second Stage Bootloader (u-boot + fsbl) used in DFU mode
  uboot-env.dfu	u-boot default environment used in DFU mode

Customizations

• Include hacks for larger bandwidth and dual core
• Add retrogram-plutosdr
• Add GNU Radio
• Remove wifi and other firmware to save space
• Use xz compression to save space

Note that the firmware boots slower than the official firmware.

Frequency correction

# ad936x_ref_cal -e 860000000 /sys/bus/iio/devices/iio\:device1/

To read the xo correction value,

# cat /sys/bus/iio/devices/iio\:device1/xo_correction

Build SDK in Ubuntu Docker

Build Docker image:

$ make docker

Log in Docker image and build SDK:

$ make docker-run
[docker] $ make sdk

Install Xilinx Vivado

On ArchLinux,

$ sudo pacman -S ncurses5-compat-libs lib32-libpng12 xorg-xlsclients xorg-server-xvfb libxcrypt-compat

Set IP Address

For example,

# fw_setenv ipaddr 192.168.3.1
# fw_setenv ipaddr_host 192.168.3.10

Power off completely then power on.

Set sample rate

out_voltage_sampling_frequency as well as in_voltage_sampling_frequency are not entirely independent, by default the both need to match unless adi,fdd-rx-rate-2tx-enable is set.

Troubleshooting

• Make sure the daughterboard is tightly connected to the breakout board

To do

• Time sync
• Separate toolchain
• Update hdl
• Package for hdl
• Package for Pluto specific stuff
• Fix for TX buffer clean
• Network / Mass storage settings
• Customize MOTD
• LED for ADRV9364
