[U-Boot-Users] Serial & Framebuffer Console together

[U-Boot-Users] Serial & Framebuffer Console together

[Praveen VS]

Hello,

Our board is customised board based on PXA255 processor, in that we have
the samsung Color LCD Controller( S6B33B0A) . 

The LCD is not interfaced to the Default PXA255 LCD pins.
IN our board the LCD controller ChipsSelect is connected to the Static
Chipselect 4 of PXA255
The LCD is a 16bpp LCD.

We are able to initialise the LCD. We are able to get the plain colors
sucessfully.
We are trying to display u-boot logo on this  16bpp LCD.But it is not
displaying..

When we looked at code bmp_logo.c , we found utility called bmp_logo, 
which converts bmp file into header
This header file is for 8 bpp & has a bmp palette field.
It tries to write the Pallette info on to Palette Ram of PXA255.

But our LCD controller is external & doesn't have pallette RAM.It only
has a standard DisplayRAM
The 16 bit colors which this controller supports doesn't have the
Pallete information.

How can we display the logo of 16bpp color depth image onto the LCD.in
U-boot?

Thanks
Reagrds
Praveen

What is not clear to you? As you can see in your log the  LCD  device
has  been  registered  as an output device, and input and poutput are
directed to the serial port. So everything looks  perfectly  fine  to
me. What did you expect?

Hello,
In U-boot Can we have serial console & Framebuffer 
Console working together.Because we are testing our LCD 
& we neeed to give some commands thro serial.

And what exactly is your problem? Just set stdin (and  maybe  stdout)
to serial, and enter your commands.

Thanks for your reply..
But we want to use both Serial ( Both for STIN & STDOUT)& 
Frame buffer LCD console for only STDOUT

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.

[U-Boot-Users] Serial & Framebuffer Console together

[Praveen VS]

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

We don't know your hardware, we don't know your driver, we don't know
how you integrated it into U-Boot.

This is not even enough information for a wild guess.

[U-Boot-Users] Serial & Framebuffer Console together

[Praveen VS]

Hello,
I am very sorry that I haven't given enough information.

Our board is customised board based on PXA255 processor, in that we have
the samsung
Color LCD Controller( S6B33B0A) .
The LCD is not interfaced to the Default PXA255 LCD pins.But it is on
VLIO

In our board the IDE is on VLIO & so also LCD 
We are able to successfully boot from the Harddisk  
Now we are trying to initialise the LCD.IN our board the LCD controller
ChipsSelect is connected to the Static Chipselect 4 of PXA255

We have followed the basic routine given in the u-boot source to
initialise the LCD,
 We are giving the  the Static Chipselect 4 ( CS4 ) address for lcd_base
(10000000 on PXA255)
After initialising we are getting the shell prompt on stdout(serial)
In that when we did the cninfo we got the following..
$ coninfo
List of available devices:
lcd      00000002 ..O
serial   80000003 SIO stdin stdout stderr
nulldev  80000003 SIO 

We are not sure if the lcd console info is correct..

Thanks
Regards
Praveen
