As a crucial embedded development tool, the embedded system debugger is usually used to debug and test embedded software 。 a embedded system debugger consists of a cross debugger and a debugger agent, which characteristic lies in the separation of running environments between the cross debugger and the debuggee and the dependence on the gdb agent in the debug session 。 with the development of embedded technique, various embedded debug techniques continuously advance and all kinds of embedded system debuggers are playing a more and more important role in the embedded software development 。 the gnu debugger, gdb as a tool in the gnu toolkits, is an extremely powerful source - level debugger 。 among gdb ’ s many noteworthy features, its ability to debug programs “ remote ” is fascinating 。 this capability is not only essential when porting gnu tools to a new operation system or microprocessor, but it ’ s also useful for developers who need to debug an embedded system based on a processor that gnu already supports 。 gdb is the preferred solution in embedded development because it provides portable, sophisticated debugging over a broad rang of embedded systems 。 this paper discusses the status quo of various embedded system debuggers ; deeply analyses the overall structure of gdb and the debugging mechanism of gdb based on its source codes ; introduces the gdb ’ s remote debug technique and gdb / mi, which are usually used to develop the gdb - based embedded system debugger 。 then dwells on how to use gdb / mi to develop a gui front and how to use rsp 、 stub and gdbserver to design a debug agent, in order to expatiate on the design method of the gdb - based embedded system debugger 。 in the end, provides a concrete implementation of the gdb - based embedded system debugger of “ embedded simulation development platform ”, the project of the innovation fund for technology based firms 。
這個特性不僅在將gnu工具移植到一個新的操作系統和微處理器的時候很有用，對于想調試一個基於gnu支持的晶元的嵌入式系統的開發人員來說，也是非常有用的。由於gdb提供了在大多數嵌入式系統上的可移植的、復雜的調試功能，它已成為嵌入式開發的首選解決方案。本文討論了當前的各種嵌入式調試器的現狀，結合源代碼詳細分析了gdb的結構和調試原理，介紹了開發基於gdb的嵌入式系統調試器常用的遠程調試技術和gdb / mi介面;然後詳細闡述了如何使用gdb / mi開發gdb的圖形前端和怎樣使用rsp協議、 stub和gdbserver設計一個調試代理，從而較深入地討論了基於gdb的嵌入式調試器的設計方法;最後，結合國家中小型企業創新基金項目「嵌入式模擬開發平臺」 ，給出了一個基於gdb的嵌入式系統調試器具體實現。 -
