In /boot/loader.conf I have for some time now the directive loader_color="NO" in order to prevent the serial console changes from my default scheme black text on white background to white on black. Since today, the serial console shows again everything white on black. Is this directive not functional anymore? How can I force the serial console keep on showing black text on white background?

The first message that I see in white on black is that efi/freebsd/loader.env was consulted. However, I cannot find that loader.env file. Perhaps, I need to add the teken.fg_color and teken.bg_color directive to this one.

We are talking about a serial console of a BeagleBone Black, which is connected via J1 over FTDI232/USB to a macOS computer. In the Mac Terminal I have running:
sudo cu -s 115200 --nostop -l /dev/tty.usbserial-00000000

Below comes a copy of the console messages between the end of reboot until Loading the kernel (s below). My original e-mail comes in formatted text, so you would see when the terminal color is switched from black on white (the default of the Mac Terminal since 20++ years) to white on black (the default of MS-DOS in the 80ths :-). The color switch happens together with the following output:

Consoles: EFI console  
    Reading loader env vars from /efi/freebsd/loader.env

The actual capture comes below, and as you can see, loader.conf is loaded afterwards.

Thank you very much for looking into this.

Best regards

Rolf
