dm9000 not found at 0x04014000 id: 0x00000000是怎么回事了？

qsxiaoyao 2008-10-27 09:30:34

在调试一块板时UBOOT已经起来，可是用ping或tftp时都会提示dm9000 not found at 0x04014000 id: 0xc0c0c0c0
我用的dm9000a，对应的驱动是dm9000x.c，按说读出来ID应该是0x90000a46才对
这样的问题一般出现在什么地方？

#define CONFIG_DM9000_BASE 0x04014000

#define DM9000_IO CONFIG_DM9000_BASE

#define DM9000_DATA (CONFIG_DM9000_BASE+2)
这几个设置是正确的，还有什么地方会引起这个问题？

我的也是这个问题，not found你的最后怎么解决了哦啊[Quote=引用 4 楼 qsxiaoyao 的回复:]
解决了，是DM9000的mode和io模式在操作后没有切换引起的

我这用方案商提供的一个二进制文件烧进去能起来，说明硬件是好的，但那个没源代码，只能自己改。
#define CONFIG_DM9000_BASE 0x04014000 这个供方说是对的，我实在找不出还有哪有问题，请高人指点。
我用的TI的TMS320DM355平台，DM355的EM_BA1脚接的dm9000的CMD

dm9000 not found at 0x04014000
#define CONFIG_DM9000_BASE 0x04014000
最容易联想的就是 base addrress不对了。

dm9000所在片选可能没设置好

本课程是linux驱动开发的第11个课程，主要内容是linux的网络驱动的介绍，首先讲述了网络设备驱动接口和之前讲的2种的不同，然后以一个虚拟网卡驱动源码学习了网卡驱动的框架，后分析了一个实际网卡DM9000的驱动细节。

这几天真被dm9000aep折磨的受不了，在今晚12.5终于宣告对它的完美征服，回顾这几天的历程，真是一波三折。 1、首先我要说的是dm9000aep和dm9000是不一样的，虽是同一个公司的网卡，但是前者是后者的升级版，如果直接把u-boot下的网卡那部分程序拿来用，最终烧到优龙板里后在u-boot下是实现不了tftp的，因为之前我已经在...
