S1D13705 Linux Console Driver
X27A-E-004-02 Issue Date: 01/09/19
Copy the remaining source files
/tmp/Config.in
/tmp/fbmem.c
/tmp/fbcon-cfb4.c
/tmp/Makefile
into the directory /usr/src/linux/drivers/video replacing the files of the same name.
If your kernel version is not 2.4.5 or you want to retain greater control of the build
process then use a text editor and cut and paste the sections dealing with the Epson
driver in the corresponding files of the same names.
4. Modify s1d13705.h
The file s1d13705.h contains the register values required to set the screen resolution,
color depth (bpp), display type, display rotation, etc.
Before building the console driver, refer to the descriptions in the file s1d13705.h for
the default settings of the console driver. If the default does not match the configura-
tion you are building for then s1d13705.h will have to be regenerated with the correct
information.
Use the program 13705CFG to generate the required header file. For information on
how to use 13705CFG, refer to the 13705CFG Configuration Program User Manual,
document number X27A-B-001-xx, available at www.erd.epson.com
After selecting the desired configuration, choose “File->Export” and select the “C
Header File for S1D13705 Generic Drivers” option. Save the new configuration as
s1d13705.h in the /usr/src/linux/drivers/video, replacing the original configuration
file.
5. Configure the video options.
From the command prompt in the directory /usr/src/linux run the command:
make menuconfig
This command will start a text based interface which allows the selection of build time
parameters. From the options presented select:
“Code maturity level” options
“Prompt for development and/or incomplete drivers”
“Console drivers” options
“Frame-buffer support”
“Support for frame buffer devices (EXPERIMENTAL)”
“EPSON LCD/CRT/TV controller support”
“EPSON S1D13705 Support”
“Advanced low-level driver options”
“xbpp packed pixels support” *
* where x is the color depth being compile for.
Once you have configured the kernel options, save and exit the configuration utility.
