Abstract
A method of debugging using a USB connecting system. A debug signal function is installed in the BIOS of a target PC, and a host PC is provided with monitor software. A USB interface is used to connect the target PC and the host PC, using the host PC to monitor the debugging state of the BIOS of the target PC. The invention thus achieves the goal of debugging a system through a USB.
Claims20
A debugging method using a USB (universal serial bus) connecting system for debugging a target PC from a host PC, which comprises the steps of:
- driving a USB interface to connect the target PC and the host PC through the USB connecting system;
- reading a flow control flag of a BIOS and detecting the value of the flow control flag;
- compiling a program code with the function of outputting a debug signal into data of the BIOS of the target PC;
- outputting the data through a transmission unit;
- and
- displaying the data on a screen of the host PC.
