У меня есть плата ARM, на которой я пытаюсь настроить NFS так, чтобы rootfs был подключен по сети. Как я могу решить это?
Моя конфигурация сервера:
ОС: Научный Linux 6.0
Мои акции NFS:
#cat /etc/exports
/tftpboot/squashfs-root 192.168.1.5(rw,insecure,sync,no_root_squash)
#showmount -e 192.168.1.100
Export list for 192.168.1.100:
/tftpboot/squashfs-root 192.168.1.5
Мои настройки цели:
U-Boot> printenv
bootcmd=sf read 0xa00000 0x30000 0x1d0000;sf read 0x3000000 0x200000 0x800000;jump 0xa00000
bootdelay=3
baudrate=38400
netmask=255.255.0.0
modelname=DEVBOARD
ethaddr=02:00:11:21:32:45
serverip=192.168.1.100

ipaddr=192.168.1.5
bootargs=root=/dev/nfs nfsroot=192.168.1.100:/tftpboot/squashfs-root nolock,tcp mem=64M console=2
