How to make driver:

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

参考程序：

网口驱动程序：

E:\Jupiter\uclinux\补丁prog\eth1driver\目录

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

eth1的驱动

将jupiter_eth1.c, jupiter_eth1.h, Space.c, Makefile拷贝到/drivers/net/,重新编译内核

uclinux 启动后执行

ifconfig eth1 up

ifconfig eth1 192.168.0.4

ifconfig lo 127.0.0.1

然后看ifconfig列出所有的网络

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

/bin> ifconfig

键盘驱动程序

E:\Jupiter\uclinux\keypad目录

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

在uclinux启动后

执行：cat /proc/devices

列出驱动设备表

另外几个参考程序：

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

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

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

最后都要重新便宜kernel
