Infos

Doom clone derived from original ID Software sources and enhanced (SDL support, bugs correction...). Doom is the sequel of Wolfenstein. It is working quite well on 8bpp framebuffers; for 16bpp one, a bug has to be corrected in i.MX framebuffer (ongoing).
PrBoom is integrated in Buildroot on latest SVN snapshots. It needs SDL, SDL_mixer & SDL_net. Currently there is no sound support on Armadeus boards. Video was taken on the new LCD. Runs at full speed in 320x240 with only ~40% CPU usage in 8bpp mode.

Install

• Launch Buildroot configuration:

# make menuconfig

Activate PrBoom package (it will autoselect SDL, SDL_mixer and SDL_net). Then, exit and save your config. Re-Build your rootfs:

# make

APF9328 with only 8 MBytes of FLASH

As the generated rootfs is too big to be put on the 8MBytes APF9328 FLASH, there are 2 solutions:

• 1] put rootfs on a MMC/SD. In Buildroot configure rootfs to be tar-ed:

Target filesystem options ---> and then:

[armadeus]$ sudo tar xvf /.../buildroot/binaries/armadeus/rootfs.arm.tar -C /media/usbdisk
[armadeus]$ sudo umount /media/usbdisk

in U-Boot then use (with MMC inserted):

BIOS> run mmcboot

After Linux boot on Target, launch the game.

• 2] put games files on NFS export: armadeus/buildroot/build_arm_nofpu/root/usr/games/prboom, armadeus/buildroot/project_build_arm/armadeus/root/usr/share/games/doom/prboom.wad and doom1.wad.!! Files should be in the same directory !! Then cd in directory and launch the game:

# /mnt/nfs/usr/games/prboom -width 320 -height 240 &

Launching

# /usr/games/prboom -width 320 -height 240 &

If SDL is complaining because it can't find any mouse (Unable to init SDL: Unable to open mouse) then, before launching the game, do:

# export SDL_NOMOUSE=1
