: Thank you very much for your help. I was able to compiled the code
: successfully after setting FBVGA=N.
:
: However, I still have another problem with the driver of my LCD frame
: buffer. I built the kernel with the (Embedded Planet HIOX) LCD frame
buffer
: support. The device file that represents the LCD frame buffer is not
The Embedded Planet box kernel supported two versions of a
framebuffer. The older MontaVista kernel supported /dev/lcd,
and the newer 1.2 CDK I believe supports /dev/fb0. Check out
the different versions of the MontaVista (www.mvista.com) CDK
for which one you have (or pull down their kernel) and you'll
be on your way.
If you are using /dev/lcd, you need to pull down an older version of
Microwindows (try somewhere in between 0.87 and 0.88) and
you will find a src/drivers/scr_fb.c which has the special
#define EMBEDDEDPLANET /dev/lcd driver, which is
now removed because of the newer fb kernel support.

Greg
: "/dev/fb0" but "/dev/lcd". When I "cat /proc/devices", the response was:
:
: Character devices:
: 1 mem
: 2 pty
: 3 ttyp
: 4 ttyS
: 5 cua
: 10 misc
: 62 lcd823
: 128 ptm
: 136 pts
:
: Block devices:
: 1 ramdisk
: 7 loop
:
: So there's no "fb" in the devices list. Instead I have "lcd823".
: As a result, when I ran the "mvdemo" or "mdemo" program, it complained
about
: "Error opening /dev/fb0".
:
: Do you have any suggestion about how to get around the problem.

: Thanks,
