OK, I will check your evb.bin when I have time.yes everything is as you say. thanks for taking a look. good luck.
Please note:
When the tablet booting, if you could find the LCD backlight turn on (even it is black colour), please wait for 2~3 min more. You should see the X window starting. I remember that the first booting was longer time than the second booting very much.
Hope could help you.
