用nfs啟動(dòng)系統(tǒng)的問題

a104727798

nand flash啟動(dòng) 進(jìn)入vivi模式，輸入以下
param set linux_cmd_line "console=ttySAC0 root=/dev/nfs nfsroot=192.168.1.21:/opt/FriendlyARM/QQ2440/root_nfs ip=192.168.1.23:192.168.1.21:192.168.1.21:255.255.255.0:sbc2440.arm9.net:eth0ff"
我的虛擬機(jī)linux是192.168.1.21 板子是192.168.1.23 我電腦是192.168.1.22，這樣設(shè)置對(duì)嗎？
出現(xiàn)這樣的情況：
IP-Config: Complete:
      device=eth0, addr=192.168.1.23, mask=255.255.255.0, gw=192.168.1.21,

    bootserver=192.168.1.21, rootserver=192.168.1.21, rootpath=

估計(jì)是你的nfs配置有問題，防火墻沒關(guān)閉

網(wǎng)關(guān)192.168.1.21?設(shè)置有問題吧。還有，啟動(dòng)NFS服務(wù)要關(guān)掉防火墻……

發(fā)現(xiàn)幾個(gè)問題，1.linux防火墻沒關(guān)。2.不是nand flash啟動(dòng)。3.板子的ip恢復(fù)到默認(rèn)的230了。
哎，問題更正后還是沒有啟動(dòng)起來，還真是個(gè)問題啊
