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。 -
Basic interoperability test is designed to check alarms on physical connections, the error rate of information delivery and the 2mbits cross - connect state when stm - 1 signals pass the transmission system. high - level interoperability test is to check the consistency of generated against readout overhead bytes, alarms and the performance monitoring as well as the synchronization, protection rotation, the interworking possibility of nm information and the o & m capability
基本互通能力測試包括：檢查物理連接是否告警，檢查信息傳送有無差錯，交換機stm - 1經過傳輸系統進行2mbits交叉連接的測試；高層次互通能力測試包括：開銷位元組產生和讀出的一致性，告警一致性，性能監視一致性，同步，保護倒換，網管信息互通的可能性及維護操作能力的測試等。 -
