Live Tuning

Live tuning features allow tuning tool to interact with target system at runtime over Ethernet interface.

Prerequisites

  • J7 EVM connected to network using Ethernet.
  • PC and EVM on the same network. PC must be able to ping the EVM.
    • VPN connection can interfere with this. Please disconnect PC from VPN before trying live tuning.
    • EVM IP address can be found using “ifconfig” on EVM Linux console.
  • app_single_cam application must be running on the EVM.

After the app_single_cam application is launched, the connection can be established by entering EVM IP address in the tool window.
