busybox-1.24.0制作AM335X文件系统         第五天

/*****************************************************************************************************************************/

开始：

1、打开telnet服务

    发现在编译Busybox时已经选择了telnet服务，只要启动telnet服务。

     在etc/init.d/rcS文件中添加启动telnet服务。

           在最后一行添加 telnetd &

2、尝试运行

     先将SD卡格式化成两个分区，分别为boot卷标的FAT32，rootfs卷标的EXT4

     可以用TI的AM335X的SDK中的SD卡制作脚本（见附件：文件名：create-sdcard.rar）。 create-sdcard.rar (5.81 KB, 下载次数: 944)

    将这前的MLO 、u-boot.img、zImage、am335x-wsdv.dtb复制到boot分区下

    将刚才做好的rootfs下的所有文件复制到rootfs分区下

    (注意：复制时要加-rfa参数)

    板子上电启动，发现停在UBOOT中，

    这时可以手动输入命令启动LINUX

    #load mmc ${mmcdev} ${fdtaddr} /${bootdtbfile}

    #load mmc ${mmcdev} ${loadaddr} /${bootkernelfile}

    #bootz ${loadaddr} - ${fdtaddr}

    此时linux已经起动启来了。

    可以看到串口打印如下信息：

reading /am335x-wsdv.dtb

31354 bytes read in 10 ms (3 MiB/s)

reading /zImage

4429464 bytes read in 330 ms (12.8 MiB/s)

2、连接网线测试ftp与telnet

     测试发现FTP可用，telnet服务端口没有打开。

     最后修改内核配置问题解决

     打开配置make menuconfig

     Device Drivers  --------->

        Character devices --------->

           //选择上Legacy(BSD)PTY support

           [  *  ]    Legacy  ( BSD )  PTY support

           (256)   Maximum number of legacy PTY in use

     重新编译内核

     启动测试，发现telnet可用了^_^

网络笔记，呵呵

正点原子
