I have a Debian on beaglebone without an X server and I need to get rid of any console output to the framebuffer device.

I was trying few things I found, like console=null or kernel argument vga=0, but without luck.

Any advice?

You do not have a vga in your BeagleBone.

In my Lamobo R1 (ARM like the BB) I am passing to the kernel the parameters

sunxi_ve_mem_reserve=0 sunxi_g2d_mem_reserve=0 sunxi_fb_mem_reserve=0 console=ttyS1,115200n8

and took out the ones:

console=tty1 disp.screen0_output_mode=1920x1080p60

Why this parameters:

sunxi_ve_mem_reserve=0

This eliminates the reserved memory for the video acceleration engine, saving 80MB.

sunxi_g2d_mem_reserve=0

This eliminates the reserved memory for the 2D acceleration engine.

sunxi_fb_mem_reserve=0

This sets the amount of total reserved memory for the framebuffer to 0.

console=ttyS1,115200n8

  • Using the console via a PL2303HX USB to UART TTL cable

console=tty1

  • Took it out because the terminal output was using the framebuffer.

Since you are not interested in video output, you might also be interested in a BeagleBone Green, a BeagleBone without a HDMI connector.
