help: armlinux的skyeye.conf

[复制链接]

发表于 2004-5-15 14:31:25 | 显示全部楼层 |阅读模式
谁能帮我贴一下典型的适合armlinux的skyeye.conf吗?
或者是用于linux-2.4.18-rmk7的，
或者是最新的用于linux src(2.4.13)patched for ep7312的。
我找不着啊。



Don't tell me to download the testsuite.
It's too large.

谢谢！我试了一下。这个是for ep7312的，请问romfs-zmrx.img是怎么来的呢？我只下到了for linux-2.4.18-rmk7的initrd.img。
run之后报mount root fs error之类的信息。
希望帮助！

在skyeye.conf中把romfs-zmrx.img改成initrd.img

改了才报cann't mount root fs, super block之类的问题，不改它会报找不着了。
而若用在linux-2.4.18-rmk7上，它干脆到starting……这第一句的位置就停了。
是不是非要自己弄一个initrd.img根文件系统盘出来呀？但这个应该比较通用啊，最好我就不要再费劲了，而且实际上主要是由于我不熟，虽然知道有这么回事。要选目录、文件，要mknod或mkdev之类的吧？选哪些？建哪些dev？

唉，还没回信。大哥们帮帮忙。小弟上回网拨回号不易呀。这个50块的TP-link的内猫要让小弟的机器蓝屏三次以上不是难事。想来驱动写得很破。(要有资料的话真想自己牛得能写个驱动才解气)

把你的错误信息详细贴出来看一下。包括使用initrd.img和romfs-zmrx.img的情况，你说的比较简单，别人很难解答你的问题的。

感谢ksh大虾出手。眼前一亮,:-)。

我因为看到前面版主回caolingzhi的帖子，其中报的问题的表现差不多；
再加上不太了解有什么好的方法将输出信息重定向出来，以为这种问题很常见，所以只说了一下情况。
以下是重定向时盲输入的，请教有无更好的方法？

我查找了一下问题出的地方，得到如下线索； 我给register_blkdev()加一些打印语句：

(mtdblock.c (?))
int register_blkdev(unsigned int major, const char * name, struct block_device_operations *bdops)
{
    printk(KERN_NOTICE "param1-major %d, 2-name %s 3-bdops %p,MAX_BLKDEV %d\n", major, name, bdops,MAX_BLKDEV);
        if (major == 0) {
                for (major = MAX_BLKDEV-1; major > 0; major--) {
                        if (blkdevs[major].bdops == NULL) {
                                blkdevs[major].name = name;
                                blkdevs[major].bdops = bdops;
                                return major;
                        }
                }
                return -EBUSY;
        }
        if (major >= MAX_BLKDEV){
                printk(KERN_NOTICE "seem exceeded the MAX_BLKDEV, return.\n");
                return -EINVAL;
        }
         
        if (blkdevs[major].bdops && blkdevs[major].bdops != bdops){
                printk(KERN_NOTICE "seems problem with bdops, return.blkdevs[%d].bdops is %p, while bdops is %p\n", major, blkdevs[major].bdops, bdops);
          //      goto SKIP;
                return -EBUSY;
        }
        
        blkdevs[major].name = name;
        blkdevs[major].bdops = bdops;
        //SKIP:
        printk(KERN_NOTICE "seem ok, return 0.\n");
        return 0;
}

然后skyeye运行显示如下：

在这里似乎是两次块设备注册的意思(?)，一个叫Blkmem，一个叫mtdblock，major都相同，为31，
但bdops不同(设备的操作函数不同)，所以程序判断有问题，返回EBUSY.这个是引起问题的原因吗?

我觉得首先skyeye.conf的文件中的内存地址应该是连续的。内存地址应该和硬件手册一致。
第一次的错误可能是因为本来是ROM的地方，不应该放initrd.img,initrd.img应该是ramfs才对。我建议你用下面的内存配置试一下：
mem_bank: map=I, type=RW, addr=0x80000000, size=0x00010000
mem_bank: map=M, type=RW, addr=0xc0000000, size=0x00200000
mem_bank: map=M, type=RW, addr=0xc0200000, size=0x00200000, file=./initrd.img
mem_bank: map=M, type=RW, addr=0xc0400000, size=0x00c00000
注意你的initrd.img不要超过2M

首先，我不知道ep7312应怎样设置为妥，也没什么硬件手册，所以想求得一个典型配置。
试了一下，还是有问题啊，输出好像一样的：

以下是试用的你建议的skyeye.conf:
cpu: arm720t

mach: ep7312
mem_bank: map=I, type=RW, addr=0x80000000, size=0x00010000
mem_bank: map=M, type=RW, addr=0xc0000000, size=0x00200000
mem_bank: map=M, type=RW, addr=0xc0200000, size=0x00200000, file=./initrd.img
mem_bank: map=M, type=RW, addr=0xc0400000, size=0x00c00000


怎么解决这个问题呢？请教原因明显吗？

噢！我错了！我刚才又试了一下for linux-2.4.18-rmk7的，ksh大虾的这个.conf起作用了！终于见到了“ARMLINUX”字样！感谢！
上面我是对linux-2.4.13 patched for ep7312试的，所以没有成功。
那么也就是说这两个的根文件系统不一样。是否ep7312的是那个romfs-zmrx.img,请问在哪儿可以找到？

直接用linux中的genromfs命令生成即可。例如：
mount -o loop initrd.img /mnt
genromfs -d /mnt -f romfs-zmrx.img
