is it just the FB selection that's causing problems?
and what do you mean by "failed"?  you'll have to
be more specific.  does the system fail to boot?
does it boot but the FB doesn't work?  etc, etc.

Sorry,I neglected some points here.Firstly,I could
make the 2_4_devel work on RPXlite DW board with
rpxlite_defconfig.Then when I added FB configuration
to build these two kernel tree,both could boot right
with "console=ttyS0,9600" but hanged after kernel
uncompressed with "console=tty0".There were no display
on LCD panel.Yeah,2.4.18 kernel can work right on
RPXlite DW board with FB and USB HOST mode
support.Also the LCD panel is NL6448BC20-08.

Thanks.

You must be joking. This is for embedded systems, and code  size  and
especially boot time are critical.

Also, this suggestion does not coder Robert's intention of preventint
the user from selecting bogus configuration options for  stuff  which
doesn't exist on his chip.

Could 2_4_devel support RPXlite DW LCD panel?

[Song Sam]

Hi,

I want to port 2_4_devel on RPXlite DW with
framebuffer support and tried linuxppc_2_4_devel in
linuxppc official BK tree and DENX tree repectively
but failed.Could anyone try it before?Worked?

----[The config part of frame buffer support]----
...
CONFIG_RPXLITE=y
...
CONFIG_FB=y
CONFIG_DUMMY_CONSOLE=y
...
CONFIG_FB_8xx_LCD=y
...
CONFIG_FB_RPX_LCD_NEC=y   ---[Linuxppc BK tree]
CONFIG_NEC_NL6448AC33=y   ---[DENX CVS tree]
...
CONFIG_FBCON_ADVANCED=y
...
CONFIG_FBCON_CFB8=y
CONFIG_FBCON_CFB16=y
...
CONFIG_FBCON_FONTS=y

Anyinput would be appreciated!
