FreeBSD not booting on Raspberry with VGA 666

[Oliver Psotta]

Hello,

FreeBSD-11.0-CURRENT-arm-armv6-RPI2-20160121-r294499 did not boot on a Rasberry Pi 2 B with the Gert VGA 666 adaptor connected to the Raspberry's GPIO port. This adaptor basically is a passive resistor network, using most of the GPIO's pins.

My guess is that FreeBSD tries to activate the serial port on GPIO and this fails. Is there a solution to turn off the serial port or set the config.txt to enable booting?

By the way I've managed to get VGA 666 working for FreeBSD with the same settings and files as for Linux and Risc OS. Of course booting stops after the message
