hi bigboss25,

sorry no french, just a french name and some "not polite" french words ;-)

you can grab my sdl sources from :

sdl for nios2 (http://drunken.intershit.com/sdl.tar.gz)

look in the file configure.nios for my ./configure options. after compiling, the library is in /src/.libs/ or in the directory you specified with --prefix.

some small example programms from :

example sdl programms (http://drunken.intershit.com/examples.tar.gz)

and a thread at gmane about uclinux and libsdl :

gmane sdl on uclinux (http://comments.gmane.org/gmane.comp.lib.sdl/4795)

the next few days i will try to use the nioswiki framebuffer with a separate external

sram chip. maybe this will speed up sdl on nios2!?

let me know if you need some 3d/opengl stuff for nios. i got picogl,tinygl and

some parts of libfixgl running.

Thanks a lot http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/biggrin.gif

Your sources will be very useful for me.

And yes, I think you really should use external SRAM to put frame buffer in it, otherwise you may overkill you memory bandwidth.

Do you use a custom board or an eval board ? If you use 2C35 NIOS2 eval board, you should consider using the external SSRAM chip to store frame buffer datas.

I will try graphics on nios2 in the next weeks and post about my experience.

Thanks again.

Regards.
