Hi, Now my question is if anybody was successful to setup kernel debugging using {host}Thunderbolt-to-FW<— FW ——>Thunderbolt-to-FW{target}. If so could you please give the args you used for nvram settings, and the steps for host machine to kick off the connection. I can issue an NMI from the target’s (Cmd + Cmd + Pow ). That’s about it. I can not connect using either lldb or gdb. Thanks, Prokash _______________________________________________ Do not post admin requests to the list. They will be ignored.
