Debugging method and debugging system of SOC chip

Abstract

The invention provides a debugging method of an SOC chip, which includes the following steps: step 102, connecting the SOC chip to a level switch device through a universal asynchronous receiver / transmitter (UART) port and connecting the level switch device to a control main machine; step 104, generating debugging operation indications received through the picture user interface into debugging orders through the control machine; step 106, conducting level switch on the debugging orders through the level switch device to generate level switch debugging orders; and step 108, obtaining and operating level switch debugging orders through the SOC chip. Correspondingly, a debugging system of the SOC chip is further provided. By means of the technical scheme, debugging of the SOC chip can be achieved through the UART port, and cost in the debugging process is greatly reduced. Simultaneously, the picture user interface is adopted to receive operation indications and generate debugging orders to achieve batch processing of the SOC chip and improve debugging efficiency.

Description

technical field [0001] The invention relates to a debugging technology of an SOC chip, in particular to a debugging method and a debugging system of an SOC chip. Background technique [0002] SOC (System-on-a-chip, system on chip) video processing chip is a collection of many IP resources, including CPU, VIDEO DECODER and many video processing modules. After the overall architecture of the chip is built, a unified debugging method is required to debug all the modules and system software in the chip. Common debugging interfaces include USB (Universal Serial BUS, Universal Serial Bus), JTAG (Joint Test Action Group, Joint Test Action Group), etc., but these debugging methods need to purchase a set of debugging tools and a debugging development environment. Tends to be more expensive. However, SOC chips generally have a hardware UART (Universal Asynchronous Receiver / Transmitter, Universal Asynchronous Receiver / Transmitter) interface, and the debugging instructions are transmi...
