Hello,
Thanks for your previous mail
We have written the routine to initialise our
Color LCD Controller( S6B33B0A)
But we are not able to get anything on the LCD Screen
We checked the coninfo we are getting like this
$ coninfo
List of available devices:
lcd 00000002 ..O
serial 80000003 SIO stdin stdout stderr
nulldev 80000003 SIO
Our LCD controller is on VLIO & uses static Chipselect CS4
We are giving statics CS4 Address ( 10000000 on PXA255) for lcd_base
We are not sure whether we need to give this address ? If not what
other address has to be given?
Is this the reason for the nothing coming on the LCD?
Thanks & Regards
Praveen

The current implementation of the I/O drivers supports only one one
device at a time, i. e. you can have output either on serial _or_ on
LCD, but not both at the same time. But you can switch any time you
like.
