[TQ210] 网络挂载文件系统

流程

  片内os起来后,从SDCARD加载uboot,然后使用 tftp 从 PC 下载 kernel,然后使用 nfs 挂载 PC 上的文件系统。

 

搭建 TFTP 和 NFS server

TFTP

  sudo apt-get install tftp-hpa  tftpd-hpa xinetd

  sudo vim /etc/xinetd.d/tftp

  service tftp  {        socket_type    = dgram        protocol       = udp        wait           = yes        user           = root        server         = /usr/sbin/in.tftpd        server_args    = -s /data/tftpdir/ -c        disable        = no        per_source     = 11        cps            = 100 2        flags          = IPv4  }

 

 

  sudo vim /etc/default/tftpd-hpa

  # /etc/default/tftpd-hpa  TFTP_USERNAME="tftp"  TFTP_DIRECTORY="/data/tftpdir"  TFTP_ADDRESS="[::]:69"  TFTP_OPTIONS="--secure" 

 

  sudo vim /etc/xinetd.conf

defaults
{
# Please note that you need a log_type line to be able to use log_on_success ont-size: 12pt; "> # log_type = SYSLOG daemon info
}
includedir /etc/xinetd.d

 

  restart tftp server: 

  sudo service tftpd-hpa restart 

  sudo /etc/init.d/xinetd reload

  sudo /etc/init.d/xinetd restart

 

  若遇到错误可查看:tail /var/log/syslog

  某些情况下要kill进程:

    ps -aux | grep tftp

    ps -aux | grep xine

    sudo kill xxx

 

NFS

sudo apt-get install nfs-kernel-serverportmap

sudo vim /etc/exports

/data/nfsdir/ *(rw,no_root_squash,sync)

 

sudo /etc/init.d/nfs-kernel-server restart

测试:sudo mount -t nfs <ip>:/data/nfsdir /mnt

 

配置bootargs

#define CONFIG_ETHADDR        d0:67:e5:18:02:a4#define CONFIG_NETMASK      255.255.255.0#define CONFIG_IPADDR        10.0.161.50#define CONFIG_SERVERIP        10.0.161.83#define CONFIG_GATEWAYIP    10.0.161.254#define CONFIG_BOOTARGS        "console=ttySAC0,115200 rw root=/dev/nfs nfsroot=10.0.161.83:/data/nfsdir ip=10.0.161.50:10.0.161.83:10.0.161.254:255.255.255.0:chuck:eth0:off"#define CONFIG_BOOTCOMMAND        "tftp 0x20008000 uImage.bin;bootm 0x20008000"

 

 

配置DM9000寄存器地址

#ifdef CONFIG_DM9000#define S5PV210_PA_DM9000_A     (0x88001000)#define S5PV210_PA_DM9000_F     (S5PV210_PA_DM9000_A + 0x300C)static struct resource tq210_dm9000_resources[] = {    [0] = {        .start = S5PV210_PA_DM9000_A,        .end = S5PV210_PA_DM9000_A + SZ_1K*4 - 1,        .flags = IORESOURCE_MEM,    },    [1] = {        .start = S5PV210_PA_DM9000_F,        .end = S5PV210_PA_DM9000_F + SZ_1K*4 - 1,        .flags = IORESOURCE_MEM,    },    [2] = {        .start = IRQ_EINT(10),        .end = IRQ_EINT(10),        .flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHLEVEL,    },};
