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

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.

Wolfgang Denk

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.

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.

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

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 ,] Thanks for you mail. We are trying to draw logo on to the LCD Screen, we are not able to see anything on it.. Regards Praveen
