Tutorial Video: How to boot uClinux on NIOS II Processor with MMU

Hi,

--- Quote Start ---

There is a LCD driver( http://www.alterawiki.com/wiki/lcd_16207 ).

Can I compile It for this linux without recompiling the kernel?

--- Quote End ---

It's possible to compile driver modules without recompiling the kernel each time, but you may once compile it and make the 'linux-2.6.x' folder.

The attached file includes the sample code of LCD 16207. Please extract it and copy 'lcd_16207.ko' to your SD or somewhere.

To load the module, type

insmod lcd_16207.ko

('modprobe' will not work). After the verbose messages, if you get

...
reltype 12 0x38 name:<device_release>
Applying relocate section 16 to 15
reltype 12 0xbc name:<init_module>
reltype 12 0x104 name:<cleanup_module>
Device /dev/lcd16207 registered

then make a 'device file' by typing

mknod /dev/lcd16207 c 250 0

and you can send your message to the LCD by

echo "Hello LCD!" > /dev/lcd16207

.

If you want to recompile this module, please refer the header comments of the source file 'lcd_16207.c'.
