Are you sure you physw_status and mmio addresses are right, if one were off by one word, this might happen ?

1.I must comment out the      physw_status[2] = kbd_new_state[2];Ohterwise,the screen is not work.
2.After comment out it.The camera can start succ with any key is disable.And I can draw text on the screen.
1  30x200xc             
2    c2000eb                 
3     2d0ff

any key have no response.
the x are digit on the screen which change all the time.I press key.Likely there is no response to the key.

I check the kdb.c many times.
I think the code in kdb.c is right.Now I think if it is some function with incorrect address cause the screen not work.
