I am getting the same problem, that LCD times out exactly around 12/13 mins. I tried to disable hsync and vsync powersaves and also power management suspend. Still the LCD times out.
Even
# setterm -blank 0
did not work.
By the way i did not find a structure like
in
Quote:
struct fb_ops mxc_fbstructure {
.open = some_function
.close = some_other_function
.blank = the_blanking_function
};
in the mxcfb file.
Though there is a similar structure like below.
static struct fb_ops mxcfb_ops = {
.owner = THIS_MODULE,
.fb_set_par = mxcfb_set_par,
.fb_check_var = mxcfb_check_var,
.fb_setcolreg = mxcfb_setcolreg,
.fb_pan_display = mxcfb_pan_display,
.fb_ioctl = mxcfb_ioctl,
.fb_fillrect = cfb_fillrect,
.fb_copyarea = cfb_copyarea,
.fb_imageblit = cfb_imageblit,
.fb_blank = mxcfb_blank,
// .fb_cursor = soft_cursor,
};
Commented out the fb_blank part and as you mentioned i get a blank display.
It would be nice if you could post more info on this.
Thanks
