Based on the embedded debugging tools ( lambdagdb and lambdatra ) which have basic debugging features , this thesis introduces some key technologies involved in a task - level debugging tool , including task recognition , running control , dynamic load / unload and binding task or task group to debug , etc . the task - level debugging system adopts cross - debugging mode , which means both of the debugger of host , lambdagdb , and the debug agent of target , lambdada , support task - level debugging feature 本論文總結了,在只具有基本調(diào)試功能的嵌入式調(diào)試工具( lambdagdb和lambdatra )基礎上,設計實現(xiàn)了一種能針對任務進行調(diào)試的任務級調(diào)試工具所涉及的若干關鍵技術,包括增加對被調(diào)試任務的識別、運行控制、動態(tài)加載卸載,以及根據(jù)用戶的不同要求,綁定某個任務(集)進行調(diào)試等。
