我的 WRT160N V3一直用jtag口连不上？

WRT160N V3的jtag口是12针，在论坛中找到的针角排列如下，之前我用并口试了没连上，想到上手有Jlink V7尝试可还是不行显示如下图，请高人指点谢谢
12Pin:
nTRST  ← 1    2 → GND
TDI        ← 3    4 → GND
TDO      ← 5    6 → GND
TMS      ← 7    8 → GND
TCK      ← 9   10 → GND
nSRST ←11   12 → GND

我增加些参数执行后就卡在Clearing Watchdog ...不动了
如果不加/dma就卡在Halting Processor ... <Processor Entered Debug Mode!>... 不动了

C:\win32>brjtag -probeonly /cable:2 /skipdetect /dma
