In this case the hardware changes when the device is connected to a service jig. The serial port won't work without an external level converter that is on the jig. I guess console= could set UPF_DEAD or something similar for 8250.c to ignore that port rather than leave it out of the plat_serial8250_port. Regards, Tony
