Fixed altfb, it was a bug to use ioremap to map return of kzalloc for sgdma descriptor table. Please see the update in unstable-nios2mmu branch of linux-2.6.git of sopc server.

Oh sorry, I forgot to commit on this. Clearly we don't need to remap 'desc1'. In my case, I only comment the code

//    desc1 = ioremap((unsigned long)desc1, ndesc_size);

out, and do 'flush_cache_all()' before the return. I will do git and check your code later.

Though getenv() is still a problem.

I think that this is only the shell problem. In 'hush' or 'bash', we need to export shell variables, like

/> TSLIB_CONSOLEDEVICE=none
/> export TSLIB_CONSOLEDEVICE

.

Now I'm tackling 'fltk' demo programs. They request 'libstdc++.so**', so I copied it, but will not run and say 'Segment fault'.(Segment? in Nios ?:)). I want to make 'core dump', but the kernel will not output those. Of course, I set 'ulimit -c unlimited'. Why?

Thank you, in advance.
