Problems solved by technology
[0002] At present, various errors often occur in the communication process between the master device and the slave device connected through the bus. For example, in the communication process between the master device and the slave device on the I2C bus, the slave device does not respond to read commands and write commands. , Continuously pull down the data line and other errors
However, in the prior art, such errors as the slave device continuously pulling down the data line generally require engineers (users) to use an oscilloscope for positioning, making it difficult for users to quickly locate errors in the communication process, and if the above errors occur on the customer's site On the shelf, there are still problems such as difficult disassembly and reproduction, which affect the debuggability of the board

The invention discloses a board card debugging method. The board card debugging method comprises the following steps: acquiring communication process information between master equipment and corresponding slave equipment; Analyzing the communication process information, and judging whether an error exists or not; If yes, generating corresponding error positioning information; According to the invention, the acquired communication process information is analyzed; whether an error exists is determined, the communication process information on the bus between the master device and the slave device which are connected by the role of the slave device is analyzed; Therefore, the corresponding error positioning information is generated when the error occurs, so that a user can more conveniently and quickly position the error in the communication process according to the error positioning information, the debugging performance of the board card is improved, and the user experience is improved.In addition, the invention also discloses a board card debugging device and system, which also have the above beneficial effects.
