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.
