Connecting to the bootloader console from Ubuntu

[Torsten Schlabach]

Dear list!

I am trying to talk to my Neo from my Ubuntu system to change some 
settings in the bootloader environment.

I can select the option "Set console to USB". After that, I get a 
message "Press [AUX] to return to boot menu". I don't press anything, 
but after about 1-2 seconds, I am back in the boot menu.

In the meanhwhile, I try

sesu cu -l /dev/ttyACM0

but I don't have that device node at all on my system.

Should I?

Regards,
Torsten
