网通给的KM300A Viking芯片的猫被刷坏了，求救。

xelite

看了坛子上了相关条目，看到有做个并口线的重新刷flash的方法，这个麻烦了。还看到有短接插针让modem的tftp服务器启动的方法，这个方法比较简单。但是试了好久也不行。有没有具体一些的方面？:L

主芯片是GS8120-174-004DC0。flash是spansion的s25fl016a，16 Megabit。这个modem和华硕的6000EV很像，只是flash用的不太一样，不是atmel的。

刷坏的现象是power灯和lan网络灯可以亮，其他的灯不亮，ping 192.168.1.1也没有反应。

我在手册里找到了如下的描述，短接的方法是可以的
4.5.2 Recovering from a Failed Upgrade
If the upgrade process fails while uploading the application code file,
(for example, your FTP/TFTP connection is lost during the process),
or if for any reason the new application code fails to boot after
loading, the device may boot to a special TFTP mode that enables
you to continue the upgrade. This procedure enables you avoid
having to re-flash the device with an entire image using a serial
connection to the flash header.

This TFTP server mode is invoked automatically when the
application checksum test fails during boot-up. If you have a serial
connection to the board, the following message will display on the
terminal:
Testing Application Checksum ... Failed
TFTP Server Started ... Please upload flash image to 192.168.1.1

In addition, all the software controlled test LEDs will blink at about
twice per second. This indicates that the application code has not
been loaded and all subsequent routine boot processes were
aborted. The unit’s built-in TFTP server is invoked and an IPenabled
Ethernet interface is set up with the following properties:
  IP Address: 192.168.1.1
  Mask: 255.255.255.0

To continue the image upgrade via TFTP, verify that the IP
properties on the PC assign it to the same subnet as this Ethernet
interface. Then, upload the new application code file via TFTP (FTP
is not supported in this mode). The LEDs will blink rapidly as the
image is uploaded.

You can also access this mode as a shortcut if you want to boot a
board solely to perform an image upgrade via TFTP. To force a unit
into this mode, begin booting the board and monitor the boot
messages on your PC. Before “Testing Application Checksum.....”
displays (or during), type “tao” and press <Backspace>. The
ordinary boot process will be aborted and the board will boot in the
TFTP mode as described above.

奇怪的是，用本站的2.55版程序报的是可以刷成功，但是用tftp命令直接刷报的是超时。是不是那个程序有问题

又是一个受害者，在用并口刷固件前，难道你没备份一份固件吗？
不要说你没啊，
找个一样的机子来一份固件吧

我备份下来的只有1.6MB。但是备份的另一个版本老一些的km300a，大小却有2MB。

我的这个版本maxipsession只能设到192，并且dhcp服务器支持的范围好像只有50几个，不能指定192.168.1.2 - 192.168.1.254 这样。所以才想升级firmware

直接做好的文件1.6M是正常的，从猫里面备份下来就一定是2M。备份的是整个flash，也就是说FLASH后面空余部分也做为数据备份到文件里面去了（当然都是FFFF)。

不知道为什么我备份下来的只有1.6M。最开始我使用web升级，开始用的是无线，我赶快停止了。换成有线后，升级报失败，重新启动后猫就不能用了。

这个猫到底可以刷什么版本的firmware。我刷的是3.A45INT2.jetSpeeed520。据说在6000EV上成功过。

ps. about 3.A45INT2.jetSpeeed520.zip (Fog Wang's own words..)

It suit for the viking 1 ADSL routers.But the DSL version turn to Y.1.24.18,not T93.X.XX.
I had try it in my ASUS 6000EV A/J.I think it suit for the other viking 1 DSL.
And I think it is the best viking 1 firmware.
hope you will like it.

顶一个，不解啊

这个应该可以刷60005EV的 固件吧

argeoo

这款就是6000EV的翻版嘛，至少PCB是一模一样。直接用6pin线刷公版软件吧。华硕这款机线路设计的不错，仿制的用料好一点应该还是可以的。至少比MT800强。
