Abstract: To solve the p roblem that it is difficult to debug embedded L inux kernel and drivers, this article re2 searches some key points of embedded L inux kernel debugging technology and discusses the feasibility of stub scheme. Finally we accomp lish a stub module which is simp le, flexible and portable. The module communicates with the GDB by using GDB remote serial p rotocol. In coordination with GDB, the module p rovides a convenient and economical solution for debugging embedded Linux kernel and drivers.
