Hi, thanks. If you need some more info write me.
Can you please test with attached patch? Does it help to solve your problem on N900?
Thanks, Anatolij
Hi! This patch solving problem on my N900.
Hi, I found a problem why code (without) this patch garbage display output. I played with code in function video_draw_cursor and every time when I tried to only read what is stored in *dest, on n900 dispaly was show some random white or blue pixel. This code not working on n900:
static u8 foo; ... for (y for (x u8 *dest foo *dest } }
But if I commented assign foo So I think that reading memory of framebuffer on n900 does not working (it also write something somewhere...) What do you think, where can be problem?
I have a suspicion that your framebuffer area configured for the display controller is not exclusively used. In another email [1] to Marek I explained where the problem could be.
Thanks, Anatolij
