    How to disable "vidconsole"?

    What am I missing? % cat /boot/loader.conf boot_multicons="NO" console="comconsole" boot_serial="YES" % conscontrol list Configured: ttyu1,ttyv0 Available: ttyu1,ttyv0 Muting: off I get boot messages on both ttyu1 and ttyv0. This is in BeagleBone Black, if it matters.

    Solved How to use LCD with BeagleBone?

    This is not about X. In general. For example, how to get console on LCD? When running the official FreeBSD 12.0 for BeagleBone I see: % grep fb0 /var/run/dmesg.boot fb0: <AM335x LCD controller> mem 0x4830e000-0x4830efff irq 43 on simplebus0 But there is no such device node. Am I missing something?

    Is it possible to get an older version of a port? I'll explain why I need it. I built sysutils/u-boot-beaglebone and discovered an issue when I use it with BeagleBone Black. I checked the version: now it's u-boot-2019.04. However, the official FreeBSD 12.0 image for the BBB comes with...

    Solved Default serial console to login?

    How to change the default serial console? I couldn't find any reference. In my case (BeagleBone Black) the boot messages and login prompt go to /dev/ttyu0. With the peripherals I use that port is not accessible, and I'd like to use /dev/ttyu1 instead. I don't care much about boot messages, but I...
