Abstract: Embodiments of the present invention provide a debugging method, a chip, a board, and a system and relate to the communications field. Remote debugging can be performed on a board having no main control CPU without affecting hardware distribution and software performance. The method includes: receiving, by an Ethernet port, a data packet and determining a current service type according to a service identifier carried in the data packet; when determining the current service type is a debugging service, writing the data packet into a memory through a bus and sending an interruption notification to a CPU through the bus; reading, by the CPU, the data packet from the memory according to the interruption notification, obtaining a debugging instruction by parsing the data packet, and sending the debugging instruction to an ASIC through a protocol conversion module.

Abstract translation: 本发明的实施例提供了调试方法，芯片，板和系统，并且涉及通信领域。 可以在没有主控CPU的板上执行远程调试，而不影响硬件分配和软件性能。 该方法包括：通过以太网端口接收数据包，并根据数据包中携带的业务标识符确定当前业务类型; 当确定当前服务类型是调试服务时，通过总线将数据包写入存储器并通过总线向CPU发送中断通知; 由CPU根据中断通知从存储器读取数据包，通过解析数据包获得调试指令，并通过协议转换模块将调试指令发送到ASIC。
