NOTES: 1) If 'flashing' - the source filename must exist as follows:
CFE.BIN, NVRAM.BIN, KERNEL.BIN, WHOLEFLASH.BIN or CUSTOM.BIN
BSP.BIN, CFE.BIN, TERNEL.BIN
2) If you have difficulty auto-detecting a particular flash part
you can manually specify your exact part using the /fc:XX option.
3) If you have difficulty with the older bcm47xx chips or when no CFE
is currently active/operational you may want to try both the
/noreset and /nobreak command line options together.Some bcm47xx
chips *may* always require both these options to function properly.
4) When using this utility, usually it is best to type the command line
out, then plug in the router, and then hit <ENTER> quickly to avoid
the CPUs watchdog interfering with the EJTAG operations.
5) /bypass - enables Unlock bypass command for some AMD/Spansion type
flashes, it also disables polling
6) When enable 64K tiny CFE option, two option combins can be uesed.
one, CFE or KERNEL choice and add /tinycfe option.
another, use TFE and TERNEL to replace CFE and KERNEL ons.
***************************************************************************
* Flashing the KERNEL or WHOLEFLASH will take a very long time using JTAG *
* via this utility.You are better off flashing the CFE & NVRAM files *
* & then using the normal TFTP method to flash the KERNEL via ethernet. *

终于知道我的JLINK为啥不能用了，原来是我升到了最新4.20版FW的缘故，降回到4.08版就可以了。 307# hugebird
这两天调试代码，RG100AA遇到JTAG挂住的问题，虽然尝试修改软件，但收效甚微。
不过还是想办法解决了。另外这个帖子里面遇到同样的问题，有兴趣的可以参考一下
https://www.chinadsl.net/viewthread.php?tid=30557
现象是这样，brjtag提示无法进入Debug模式，1.6r -1.7t所有版本都会挂在这里，不能继续，
Halting Processor ... <Processor did NOT enter Debug Mode!> ... Done
挂住的原因是：处理器由于flash 启动扇区的混乱代码造成进入非正常状态，无法响应jtag调试中断，所以调试指令无法被响应执行。
解决方法： 在打开modem电源之前，将flash的输出使能OE#引脚接地，再打开电源，
释放OE的短接线，最后执行Brjtag代码。
附件里的这个版本加入了 Spansion S29GL128N 16MB flash的支持，没有设备测试不知道ID检查是否正确，S29GLxxxN系列的flash采用的是统一扇区架构，S29GL128有128个扇区，每扇区128KB。
如果不能正确检测ID号，可以强制使用/fc:78定制使用新加入的16MB芯片参数。
因为这个新的16MB flash是128KB扇区，而NVRAM只有64KB，所以删除或者写操作NVRAM可能会出现问题，原ejtag代码没有考虑这一点，我一直想改这部分代码，因为没有时间，所以到现在也没去修改。如果有人要清NVRAM，还是用TTL在CFE系统里去擦除吧。
顺便说一下，-probeonly 现在可以显示未知flash芯片的ID号，便于增加新的芯片参数。
[ 本帖最后由 hugebird 于 2008-7-13 05:20 编辑 ] 不错的软件，刚好支持我的BCM6358，可惜我没JTAG线。 不知道我的S29GL128N10TF101要用哪个fc参数。 顶，修复的好工具:victory: :( 不会用。。有教程吗 楼主能帮下我吗？我的Flash是S29GL128N10TFI01，，，是个16M的Flash，下边有这个Flash的PDF文件，能不能帮下编译个可以支持这个Flash的版本发给我啊。先谢谢啦。
下图为我的猫的接口，看样子应该是JTAG接口，不过不知道针脚定义和JTAG的线如何做法。帮下啦。
现已经知道，2.4.6.8.10.12为GND其它的就不知道了。
