又扣我猫粮

binyue009 发表于 2009-8-26 18:14:12

在这里,没有粮可什么都不能做呀

可惜我没JTAG线。

熟悉Broadcom路由器的朋友，应该知道HairyDairyMaid WRT54G DeBrick JTAG工具。此次发布的是个Mod版。主要增加了对Big Endian BCM6338,6348等Broadcom DSL芯片的支持，修正了DMA数据访问和字节颠倒的问题，读写时间大 ...

RG100A已经被折腾坏了，只有试试这个了。

不错!有空研究一下!

271# hugebird

1.7j 增加了2个开关，

/pracc0使用HD最初的Pracc代码，速度慢，兼容性好
/ejtag0jtag读写周期加入20ns延时，确保高主频机器的兼容性

有人要1.5的源码，抱歉我也没有，这只是个中间版本。用1.7j吧

另外ST 和EON的flash ID只是从手册上查到的，没实际测试过，如果检测不到请用下面命令，把结果贴上来

brjtag17j -probeonly /verbose

hugebird 发表于 2009-9-4 03:19:24

271# hugebird

对了，1.7j最大的亮点是它现在可以自动检测63x8系列flash访问的地址。基本适合所有的cfe了，前面天涯遇到的alice CFE 访问地址不要加 /window:1e000000开关了
