Hello,
I am having trouble with running SDL games on Techsol’s TPC-57 computer
using the fbcon video driver on ARM Linux. You can find some
information on this computer in this press release:
http://www.medallionsystem.com/products/News/TechsolProductNews_TPC57.html
The games in question are prBoom (a Doom source port using SDL) and
Abuse-SDL. The behaviour differs depending upon whether or not I
comment out the following ioctl call in SDL_fbevents.c:
ioctl(keyboard_fd, VT_WAITACTIVE, current_vt);
If I comment out this line, prBoom and Abuse-SDL both crash with a
segfault in the SDL_FillRect function. If I uncomment the line,
execution of the two aformentioned games hangs in the ioctl call while
waiting for a certain virtual terminal (VT) to be activated.
Here are some backtraces:

As you can see, I am using 320x240 resolution. The TPC-57 uses the
s3c2410fb frame buffer driver and Linux kernel v2.6.12. The colour STN
display’s maximum resolution is 320x240. I know that the frame buffer
works, because both the testsprite program and an SDL Mandelbrot program
(http://www.temnet.org/wendigo/fractals/) work fine. I can also copy
bitmaps to /dev/fb0 and have the image displayed on the framebuffer.
“cat /dev/urandom > /dev/fb0” and “cat /dev/zero > /dev/fb0” both work
too. 
I am cross compiling all applications using Techsol’s OpenEmbedded
toolchain in a chroot environment hosted on my x86 Linux PC. The GCC
version is 3.4.4.
I do not remember exactly which ./configure command line I used the last
time I rebuilt SDL, but it would have been similar to the following:
./configure --prefix=/home/devel/sdl --build=i686-pc-linux-gnu
–host=arm-linux --enable-oss --disable-alsa --disable-esd
–disable-arts --enable-video-fbcon
–x-libraries=/home/devel/projects/oe/01/build/tmp/work/arm-linux/diet-x11-6.2.1+cvs20060206-r6/install/diet-x11/usr/lib
–without-x --x-includes=/usr/X11R6/include --enable-debug
–with-sdl-prefix=/home/devel/sdl --without-opengl --without-nasm
–without-mmx
I am using SDL v1.2.9, by the way.
Please let me know if there is something else that I should have mentioned.
Thanks,
Brolin
