学做家庭树网站,html 购物网站,wordpress 字典,网站建设的工作计划在厂家提供的dm9dev9000c.c上修改#xff0c;
1、注释掉#ifdef MODULE #endif
2、用模块化函数修饰入口出口函数
3、在dm9000c_init入口函数#xff0c;增加iobase (int)ioremap(0x20000000,1024);irq IRQ_EINT7;
4、一路进入#xff0c;在dmfe_probe1中注释掉if((db…在厂家提供的dm9dev9000c.c上修改
1、注释掉#ifdef MODULE #endif
2、用模块化函数修饰入口出口函数
3、在dm9000c_init入口函数增加iobase (int)ioremap(0x20000000,1024);irq IRQ_EINT7;
4、一路进入在dmfe_probe1中注释掉if((db-chip_revision!0x1A) || ((chip_info(15))!0) || ((chip_info(12))!1)) return -ENODEV;
5、dmfe_open中if (request_irq(dev-irq,dmfe_interrupt,0,dev-name,dev))修改为if (request_irq(dev-irq,dmfe_interrupt,IRQF_TRIGGER_RISING,dev-name,dev))
6、在出口函数dm9000c_exit中增加iounmap((void *)iobase);
7、增加头文件#include asm/irq.h #include asm/delay.h #include asm/io.h #include asm/arch-s3c2410/regs-mem.h
编译通过。
8、在dm9000c_init入口函数里添加时序volatile unsigned long bwscon; volatile unsigned long bankcon4; unsigned long val; bwscon ioremap(0x48000000,4); bankcon4 ioremap(0x48000014,4); val *bwscon; val ~(0xf16); val | (116); *bwscon val; *bankcon4 (16); iounmap(bwscon); iounmap(bankcon4);
编译通过。
9、测试驱动在内核/drivers/net中替换.c文档修改makefile编译新的uImage。烧写后启动 # ifconfig eth0 Link encap:Ethernet HWaddr 00:60:6E:33:44:55 inet addr:192.168.42.222 Bcast:192.168.42.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:317012 errors:0 dropped:0 overruns:0 frame:0 TX packets:1239 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:32863664 (31.3 MiB) TX bytes:191590 (187.0 KiB) Interrupt:51 Base address:0xa000
