Hi,

Is the LCD being enabled in the prebuilt image ? You can test it by issuing 

ls /dev/lc*. If you can find a device /dev/lcd this indicates LCD is enabled.

If  LCD is not enabled you have to build a image with LCD enabled. Refer

this  link for enabling LCD. Refer this link for LCD commands

Thx,

Hello, Prabhakar Lad!

Thank you for answering.

I built uImage with options from that link. Now there is device /dev/lcd. 

I typed (through COM port in TeraTerm):

#target: echo ^[[LD > /dev/lcd 
#target: echo "Hello" > /dev/lcd

... but nothing! Screen is black. 

By the way,

these settings are for Character LCD, aren't? But I have no such character LCD. 

I have only WQVGA 4.3" LCD panel. 

P.S. From configuration help file:
Please take care while choosing this option, Graphical LCD will
not be functional if Character LCD is selected.

What does it mean?  WQVGA LCD panel can be as Character and Graphical LCD or not? 

Please check out my settings

So. When Linux starts I can see in virtual terminal:

On the LCD I see only the logo of Texas Instruments. But I really need in console output on LCD (WQVGA 4.3" LCD panel). Thanks for any advice!!!
