thanks for the reply.
in my board, there is a sharp lcd display.
We are using RFBI. and manual update.
So after configuraing dispc, rfbi, sharp from omapfb_do_probe
calling fbdev->ext_if->transfer_area(240,320,omapfb_cb,fbdev); return 0;
I see linux logo and debug prints but after some boot time prints, it
stop refresing the display.
I mean I cant see any more prints. (I have few prints in key press).
But if I use printk("omap_irqH\n"); in omap_dispc_irq_handler. I saw
all prints coming including key press.
I mean if I use that printk then display is working.
let me know if you need any more info.
Regards,
-SG
