How to make driver:

in driver directory ~uClinux-eisc\uClinux-2.4.6（ 或20）\drivers\mydriver

write a driver file

in ~uClinux-eisc\uClinux-2.4.6\drivers\mydriver\Makefile

append the line

###################

obj-y += mydriver.o

###################

 

and execute the ~uClinux-eisc\uClinux-2.4.6\Makefile

reference program:

ethernet driver：

E:\Jupiter\uclinux\Patch prog\eth1driver\

and E:\cygwin\home\administrator\uClinux-eisc\uClinux-2.4.20\drivers\net\jupiter_eth.c  , jupiter_eth1.c,  space.c,  makefile

Driver of eth1

Put jupiter_eth1.c, jupiter_eth1.h, Space.c, Makefile to /drivers/net/, re-compile the kernel.

Boot uclinux, then do:

ifconfig eth1 up

ifconfig eth1 192.168.0.4

ifconfig lo 127.0.0.1

Use ifconfig to take a look:

===============================================

/bin> ifconfig

Keypad driver

E:\Jupiter\uclinux\keypad

and E:\cygwin\home\administrator\uClinux-eisc\uClinux-2.4.20\drivers\char\ jupiter_keypad.c  Makefile

 

Boot uclinux

Execute：cat /proc/devices

to list the device table.

 

Other driver program：

/drivers/char/serial_se3208.c    ==> UART

/drivers/char/dmc9512_ts.c       ==> touch pad

/drivers/net/jupiter_eth.c       ==> ethernet

 

Note do re-compile the kernel every time you add driver.
