推一台好玩的AP--Sparklan WX6615GT可以刷Tomato (http://www.mobile01.com/topicdetail.php?f=110&t=371211&p=1)
這一台AP是由 正文集團 Linksys WRT54G & Nergear WGR614的ODM廠 做的
所以 WRT54G 的第三方任體 很多這台機器可以用
但他跟 WRT54G 一樣 Debug port 是使用 JTAG 有別於像 Fon or 其他ADSL Router 的 MAX232

不知道有沒有人知道怎樣 用 MAX232 接 JTAG?
我搜到的資料 JTAG 都是做 JTAG-to-LPT (並列埠) 的線!

我想找接入這台AP Debug port 的 console線
由目前搜尋到的資料看來應該也可以刷 FON or OpenWrt 的韌體才對

翻了三天資料測試了兩天終於讓我try出來了@@!
原來位於 燈號排插 旁邊的 J5 才是接 MAX232 (RS-232) 的 Debug port 同 FON 一樣
接正確就直接進入
以印刷版上有小箭頭指示的地方設為PIN1的話


TX - 1　2 - VCC
NC - 3　4 - VCC
NC - 5　6 - GND
RX - 7　8 - GND
NC - 9

接腳順序跟找到的所有資料都不一樣@@!
上述腳位 NC 部分用三用電表量出應該是空接腳

一開始找錯方向了找 CONN1 那個 JTAG 好像需要擬真器 or 研發平台做橋接@@! 這部分我就不知道了
