By default, Buildroot(Ver. 2012.11.1) use /dev/ttyO2.

This is the serial port of Pandaboard. But if i would like use only HDMI, How-to setup buildroot config ?

i think you are a litte confused. /dev/ttyO2 is for the UART/serial
port. what you probably want is to enable the framebuffer console, in
which case you will get a 'console' on HDMI. make sure that you have
CONFIG_FRAMEBUFFER_CONSOLE enabled.

CONFIG_FRAMEBUFFER_CONSOLE is enable.

I set /dev/ttyO0 115200 in buildroot

It's a pandaboard es.

Perhaps, options is passing in bootargs on u-boot ???

do you have DSS enabled? is your screen turning ON and OFF during the boot?

is fbcon built statically or dynamically? if as a module, you might
need to load it.

I have build the kernel with omap support (not in module) and the screen when i boot it's 2 penguins but i have no message during the boot of the screen (hdmi) but in the serial port.

The port to use it's /dev/fb0 ? and what the speed (to set in the menuconfig of buildroot) ?

re-creating my buildroot env, then I will try to see what's going
wrong, and let you know.
