STC15W104

逆向STC-ISP V6.86E(IDA Pro)


由於司徒想要在N900上開發STC15W104程式,希望所有東西都在N900上完成,當然,包含也燒錄步驟,因此,首要步驟就是先取得Linux平台上的STC-ISP燒錄軟體,不過,原廠並沒有Linux平台上的相關資源,因此,也不可能提供Linux平台上的燒錄軟體,更不可能提供燒錄的Protocol,實在是相當遺憾的做法。雖然網路上,有一些熱心的開發者有提供自製的燒錄軟體,如:gSTC-ISP、stc-isp、stcflash、stcgal,不過支援的STC單晶片型號還是不及Windows STC-ISP多,因此,司徒打算使用逆向工程的方式去逆向Windows STC-ISP,而目前最新的版本是V6.86E(sha1: a36cc41f89170c7f4de283e4ec34f42c251d728e),因此,司徒就鎖定這個版本,因為逆向的過程還蠻花費時間的,因此,司徒將利用空閒的時間,慢慢的逆向Windows STC-ISP,期望有多餘時間可以逆向移植到Linux平台上。

首先使用OllyDBG打開確認載入的模組


0x73dd22b5就是OnCmdMsg@CCmdTarget的入口點,可以參考司徒的其它逆向文章


0x73dd238f為AfxFindMessageEntry()入口點,在下一行設定條件式中斷(Shift + F2)


條件為ebx==111(WM_COMMMAND)並且eax!=0(代表需要執行觸發事件)


設定後


接著按F9執行
