Denis,
In the "directfb-src-0.9.22\systems\fbdev\fbdev.c", this function
"dfb_fbdev->framebuffer_base = mmap" failed, maybe ucLinux does not
support this function.
Do you know which directfb version had been ported to ucLinux? How to
download it?
Thanks!
static DFBResult
system_initialize( CoreDFB *core, void **data )
{
DFBResult ret;
CoreScreen *screen;
long page_size;
...
/* Map the framebuffer */
dfb_fbdev->framebuffer_base = mmap( NULL,
dfb_fbdev->shared->fix.smem_len,
PROT_READ | PROT_WRITE,
MAP_SHARED,
dfb_fbdev->fd, 0 );
if ((int)(dfb_fbdev->framebuffer_base) == -1) {
D_PERROR( "DirectFB/FBDev: "
"Could not mmap the framebuffer!\n");
SHFREE( dfb_fbdev->shared );
close( dfb_fbdev->fd );
D_FREE( dfb_fbdev );
dfb_fbdev = NULL;
return DFB_INIT;
}
...
}
Best regards,
Sing
