Broadcom路由DSL猫用的JTAG工具最新版

谢谢，大了，无法用语言的感觉为大家提供这么好的工具

spanning

再次学习，等JTAG线到了就开搞

今天用brjtag 1.8c刷ST M29W128GH  新flash芯片的rg100a，指令如下：


1、输入 brjtag -probeonly /erasechip /fc:94 全片擦除flash芯片数据

2、输入 brjtag -flash:tfe /fc:94  写入hugebird提供的USR9113  M29W128GH 的改版cfe，
   遇到一个问题是写入速度非常非常慢，20多分钟才写入1%并且好像停在那里，很久才动一下，
   显示如下，不知是机器问题还是brjtag程序问题？

速度慢，一种可能是jtag线，另外就是pc机与jtag线和modem的配合存在问题。
第一种情况仔细查一下并口接地引脚是否都焊好。另外jtag线不能太长。
第2种情况，可以尝试换台电脑，还有就是命令上加些参数:
增加命令时延

1. brjtag -flash:tfe /ejtag0

复制代码

改用Pracc模式访问

1. brjtag -flash:tfe /nodma

复制代码

pracc加时延

1. brjtag -flash:tfe /ejtag0 /nodma

复制代码

取消写入等待。

1. brjtag -flash:tfe /bypass /ejtag0

复制代码

另外尝试giveio.sys的其它版本。

因为问题的机理不清楚，没有最终解决办法 。另外/fc:xx 不需要加

HUGEBIRD大侠，我也遇到擦很快写较慢的问题，我认为还是giveio.sys还要改进，按说1.8C很先进的，但是写不很正常，问题应该在giveio.sys没有改进上。呵呵，您是行家，你参考。

1、giveio.sys 我用的是一楼的压缩包里面的版本
2、不加 /fc:94 参数，我的机器上无法自动认出ST M29W128GH  新flash芯片
3、JTAG线是在淘宝上买的成品线，双列10PIN ，1和11脚空着  ，6脚取的GND，其它3 5 7 9连接了。

只有先尝试换台电脑看看了，其次就是加参数试试。

昨晚电脑没关机刷了一晚  还是在3％ 早上只有停掉了。

贴一下下面命令的显示结果，flash不能自动检测肯定有问题。 如果连flash都检测不到，强刷也没用。/fc：xx命令不是这么用的。

1. brjtag -probeonly /verbose

复制代码

这不是已经自动找到芯片参数了吗，1.8a开始cfi只要能自动检测到参数的芯片都报成CFI兼容，并给出芯片生产厂商。操作只关心芯片参数是否识别正确，芯片代号对操作不能提供任何帮助。

看来刷新慢最好还是换太电脑试试。
