Re: ##3 Frame Buffer Questions?

["Steve Spano" <steve@flconsult.com>]

Hi There

Thanks again for the help - very much appreciated.

Still not seeing the terminal on the display.

We have linux running in a FPGA. The FPGA has a vga-ish hardware core
inside of it. The core transfers 16/32bit pixels from the frame buffer
to the display.

It looked like there were options for a display that had a built in
character generator and there were options for the "VGA console"

Do you (or someone) have an autoconf.h that you could share for a linux
build that properly displays the bash/logins/startup on a VGA display?

Thanks so much!

CONFIG_VT=y;
CONFIG_FRAMEBUFFER=m or y (of course)
CONFIG_FRAMEBUFFER_CONSOLE=y (or CONFIG_FRAMEBUFFER_CONSOLE=m followed
by modprobe fbcon)
CONFIG_FONT_8x16 (or any built-in fonts available).

In your boot parameters, include console=tty0, just to be sure.
