以上是我终端输出的全部内容

现在有个问题
DM9000驱动在友善mini2440开发板上加载成功，但启动设备时出现 WARNING: no IRQ resource flags set.
我用printk跟踪了下，发现在初使化函数dm9000_probe()里面 就出现个怪现像（最初在这里发现问题）---EINTMASK 的第七位不能置0
也就是说不能enable EINT7 ，可是这个DM9000的INT就是接在EINT7 上了（硬件连线我没法改啊）
这导致后面启用设备时，dm9000_open()调用出现WARNING: no IRQ resource flags set。

程序运行到这里就没反映了，过几分钟后会出现下面的错误。我想知道为什么EINTMASK的第七位不能清零（其它位都可以），烦请各位帮帮我。dm9000驱动源码，已经附在后面了

[Quote=引用 7 楼 pottichu 的回复:]
GPF7 已经设置成了外设模式呀。
writel(((readl(gpfcon)&0x3fff)|0x8000),gpfcon);

那你启动以后看一下
cat /pro/interrupt
会不会是有其他设备已经占用了 EINT7 ?

个人觉得就是那一位没enable起来，所以后面一连带的问题都出来了。

就是不想动硬件，我才跑到这里来请教的，因为用友善之臂提供的 内核+rootfs是可以正常上网的，说明硬件不会有问题
正因为如此，所以我没先 飞线---我怕，飞了线之后，那一位又起不来就!@$##$%^。
如果不是硬件问题，飞线也没办法啊。

[pottichu]

http://blog.chinaunix.net/u2/84348/showart_1387402.html

移植dm9000驱动 要改的地方也就那么几处，实在不行，飞条线应该也没关系吧。

我就是按这两篇文章来移植的。。(他们的都有点问题（那是细节问题，不要照搬就行了）)

还有，他们给的头文件也因为版的问题不能用（后来我就没用那些头文件，编译也通过了）

现在我在看 光盘里的那个源码（它那个在2.6.13内核上可以用），希望能把2.6.27内核（自带）的那个整合成 符合我要求的


这只是个实验板，在硬件没出问题的时候还是不要飞线.以后还要做别的实验。问题出在软件，不想就这么放弃了。
对了，在linuxsir上面我看到也有一个人碰到这问题，有很久了，他应该也没搞定，没下文了。

碰到这问题的人 应该不多，就拿来研究下吧

呵呵。

经过修改之后 cat interrupts的结果

[root@(none) /proc]# cat interrupts

但是问题还是没有解决，如下

[root@(none) /proc]# ifconfig eth0 up

[root@(none) /proc]#


参考了他原来的代码，虽然eth0没能up 起来，但如红色部分所示，第七位已经成功置0了

那位 老师能帮我解答
WARNING: no IRQ resource flags set
Resource temporarily unavailable
在这里的原因？

[Gdatasheet]

现在
bwscon:221d1110
gpfcon:95aa
extint0:42222222

输出的数据表明，我应该设好了

但eth0还是起不来。。。

我突然发现 一个新的怪现像。。

当我执行三次ifconfig eth0 up后，再cat interrupts
结果
如红色部分所示，51号中断有三个。。。。

执行4次ifconfig eth0 up
他就变成四个eth0，但网卡还是没起来（执行ifconfig 没有输出活动的网卡）
真是奇怪了。

我已经弄好了,你可以看看这个,丢包就是用他的总线配置语句解决的
http://blog.chinaunix.net/u1/34474/showart_400516.html
不过还有一点毛病就是ping停不了,我想应该不是ash的不能接收控制台中断的问题,再查查看

[Gdatasheet]

你的解决了、？

是BWSCON寄存器的设置问题吗？

对了，你的ping停不了，应该如你所猜。

我先试试，希望你早那个问题早点解决~
