LCD controller

The LCD controller driver module (pxafb) is configured by default for the 640x480 TFT

display (part number NL6448BC20-08E), which is an optional addition to the ZEUS

Development Kit. The driver module can be loaded using the normal modprobe

command:

# modprobe pxafb

In order to use other LCD modules, extra parameters must be passed to the modprobe

command, either on the command line or using one of the methods described in the

AEL Embedded Linux Technical Manual. The options are given as a comma separated

list of parameters. Where a parameter requires a value, it is separated from the

parameter name using a colon. The available parameters are listed in the following

table. The default values shown are suitable for the NL6448BC20-08 TFT display

optionally supplied with the kit. The registers referred to are described in section 7.5.5

of the PXA270 Processor Developer’s Manual, which is in the /references/ folder on

the Development Kit CD.

Parameter Description Default

Mode The required video mode written as:

XRESxYRES-BPP

Where XRES is the X axis resolution, YRES is the

Y axis resolution and BPP is the desired bit depth.

The hardware supports bit depths of 1, 2, 4, 8 and

16-bits. The LCD driver is known to work well in 8-

or 16-bit mode.

This parameter corresponds to the LCCR1[PPL],

LCCR2[LPP] and LCCR3[BPP] registers.

mode:640x480-16
