最新消息,今日无事收了个WLA-G54迷你AP,在网上找了找都说刷成砖的,找不了JTAG口,刚好我有个WBR-G54,,,手多将CPU拆下来了,用表测量得出JTAG在CPU座上的脚位,看根据大概的位置,以WLA-G54C的PCB板上有几个引线,本是接电阻到地的,但空出来了,刚好空出4个位,最后查得
R317对应7: TMS
R314对应9: TCK
R315和R316是3: TDI, 5: TDO
就这两个不确定是对应3: TDI, 5: TDO
按思路R315是对3: TDI
R316是对5: TDO
等拿到相机再上图

JTAG pinout for Buffalo WLA-G54 / WBR-G54:
jtag is pins 1-12 (normal jtag pinout: 3: TDI, 5: TDO, 7: TMS, 9: TCK)
