求助：MX29LV640BBTC-90无法被BRJTAG2.05识别。

我的这个路由器是H618B 原为M29flash现换8M为MX29LV640BBTC-90 。可是不能被识别到
有时候用C:\brjtag>brjtag -probeonly /cable:2 可以识别为/fc:107 (00C2 22CB) ........... MX29LV640EB/DB
请大侠帮忙看下是没有焊好还是什么原因
C:\brjtag>brjtag -probeonly /cable:2

而且刷机的时候一直卡在 Erasing block: 1 (addr = 1C000000)...
经常会出现BRJTAG 错误关闭 我的是WIN7 系统 使用的是JLINK V8 安装了LIBUSB-WIN32 驱动
