Requirements
AM6xA EVM must be connected to network via Ethernet.
The PC and EVM must be connected to the same network. The PC must be able to ping the EVM.
A VPN connection can interfere with this. Please disconnect the PC from VPN before trying live tuning.
Find the EVM IP address using
ifconfig
on the EVM Linux console and enter it in the box as shown below.
Figure 9-1
EVM IP Address
Run a GStreamer pipeline so that (1) sensor streams a raw image to AM6xA and (2) AE, AWB, and tuning server in GStreamer are also running.
