通过BOOTWARE基本段加载扩展段操作指导
当Bootware基本段能够启动,而Bootware扩展段由于损坏等原因导致启动失败的时候,可以通过在基本段加载扩展段的方式,来引导扩展段启动。 具体操作步骤如下:
步骤一、设备上电,当出现System is starting...,输入Ctrl +D,进入基本段,出现如下类似界面:
======================
<1> Modify Serial Interface Parameter <2> Update Extend BootWare <3> Update Full BootWare <4> Boot Extend BootWare <5> Boot Backup Extend BootWare <0> Reboot
============================================================================
步骤二、输入1,选择修改波特率 注:本案例设备默认波特率是9600。
Enter your choice(0-5): 1
===============================
Note:'*'indicates the current baudrate
Change The HyperTerminal's Baudrate Accordingly ---------------------------
============================================================================
步骤三、为了加快上传速率,输入5,选择使用最大波特率115200(注意:将PC恻波特率同步修改为115200)
Enter your choice(0-5): 5
Baudrate has been changed to 115200 bps.
Please change the terminal's baudrate to 115200 bps, press ENTER when ready. The current baudrate is 115200 bps
===============================
|Note:'*'indicates the current baudrate Change The HyperTerminal's Baudrate Accordingly ---------------------------
<2> 19200 <3> 38400 <4> 57600 <5> 115200* <0> Exit
============================================================================
步骤四、输入0,返回操作主界面
Enter your choice(0-5): 0
======================
<1> Modify Serial Interface Parameter <2> Update Extend BootWare <3> Update Full BootWare <4> Boot Extend BootWare <5> Boot Backup Extend BootWare <0>
Reboot
步骤五、输入3,选择下载Bootware文件,下载。
Enter your choice(0-5): 3
Please Start To Transfer File, Press
Download successfully! 329344 bytes downloaded!
PC侧超级终端发送文件的设置如下:(注意:将PC恻波特率同步修改为115200)
步骤六、下载完成后,按照提示操作,升级基本段和扩展段。
Updating Basic BootWare? [Y/N]Y Updating Basic BootWare...............Done! Updating Extend BootWare? [Y/N]Y Updating Extend BootWare...........Done!
步骤七、升级完成后,进入主菜单,如同步骤2进入修改波特率菜单,把波特率修改回默认的波特率,例如:本案例是9600。(注意:将PC恻波特率同步修改为9600)
===============================
Change The HyperTerminal's Baudrate Accordingly
---------------------------
============================================================================ Enter your choice(0-5): 1
Baudrate has been changed to 9600 bps.
Please change the terminal's baudrate to 9600 bps, press ENTER when ready. The current baudrate is 9600 bps
步骤八、输入0,返回主菜单,再次输入0,重启即可。
===============================
---------------------------
<4> 57600 <5> 115200 <0>
Exit
Enter your choice(0-5): 0
====================== 0.00)>======================= <1> Modify Serial Interface Parameter <2> Update Extend BootWare <3> Update Full BootWare <4> Boot Extend BootWare <5> Boot Backup Extend BootWare <0> Reboot ============================================================================ Enter your choice(0-5): 0
