錯(cuò)誤很明顯啊，自己不好好看kernel打印的消息
你這個(gè)是把NFS做根文件系統(tǒng)吧
首先是網(wǎng)卡沒驅(qū)動(dòng)起來，可能網(wǎng)卡驅(qū)動(dòng)有問題，
IP-Config: No network devices available.
后面還有沒有NFS server
Root-NFS: No NFS server available, giving up.
可能你的主機(jī)上的NFS沒有啟動(dòng)，或者NFS啟動(dòng)了，但是防火墻開著，導(dǎo)致NFS不能正常使用
后面就是NFS不能當(dāng)根文件系統(tǒng)，然后kernel嘗試本地文件系統(tǒng)，但是你那個(gè)mtdblock2又搞成unknown了
后面的報(bào)錯(cuò)不重要，關(guān)鍵是要把網(wǎng)卡驅(qū)動(dòng)以及啟動(dòng)配置搞定，還有就是主機(jī)上的NFS server要能用
作者: geyingzhen 時(shí)間: 2009-12-6 12:32
非常感謝，查看了一下內(nèi)核配置(menuconfig)發(fā)現(xiàn) 是沒有選擇NFS支持，是內(nèi)核的問題
作者: geyingzhen 時(shí)間: 2009-12-6 12:45
小弟剛學(xué)驅(qū)動(dòng)開發(fā)，對(duì)這一塊不是太熟悉，不過有了這回以后會(huì)注意的！
