Referring to fig. 2, in an implementation manner of the present embodiment, the communication chip 100 includes a hardware wireless debugging apparatus 110, a memory 120, a debugging control module 130, and a wireless communication module 140. The hardware wireless debugging device 110 is a virtual device of the program code stored in the memory 120, the debugging control module 130 is a separate hardware module capable of reading or changing the hardware information of other functional modules in the communication chip 100, and the debugging control module 130 can read or change the hardware information of other functional modules in the communication chip 100 when the hardware wireless debugging device 110 is operated.
Referring to fig. 3, in another embodiment of the present invention, the communication chip 100 includes a memory 120, a debugging control module 130, a wireless communication module 140, and a processor 150. The debug control module 130 may be a program firmware code stored in the processor 150, and the processor 150 may read or change hardware information of other functional modules in the communication chip 100 when running the code of the debug control module 130.
The components of the communication chip 100 are electrically connected to each other directly or indirectly to achieve data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines.
The Memory 120 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read-Only Memory (PROM), an Erasable Read-Only Memory (EPROM), an electrically Erasable Read-Only Memory (EEPROM), and the like.
The wireless communication module 140 is used for testing the terminal communication connection, and the wireless communication module 140 may be a WiFi communication module.
The present embodiment provides a hardware wireless debugging method applied to the debugging terminal 200 and the communication chip 100 shown in fig. 1.
When the communication chip 100 receives the debugging terminal 200 to debug the communication chip through the wireless interface, the debugging terminal 200 can passively receive and observe the content of the wireless interface, but a general debugging method cannot actively acquire the hardware information of a specified position in the communication chip 100, and cannot actively modify the hardware information. If the hardware information of the communication chip needs to be actively read or modified, the debugging needs to be performed by adopting a JTAG, UART and other wired connection modes.
Therefore, in this embodiment, the debug control module 130 is designed in the communication chip 100, the debug control module 130 can read or change hardware information in the communication chip 100, the debug control module 130 cooperates with the wireless communication module 140 to multiplex the wireless communication module 140 to receive a debug instruction for hardware sent by the debug terminal 200, and the debug control module 130 reads or changes the hardware information according to the debug instruction.
Referring to fig. 4, fig. 4 is a flowchart of the hardware wireless debugging method, and the method including various steps will be described in detail below.
In step S110, the debug terminal 200 generates the debug command into a debug packet with a preset format, and wirelessly transmits the debug packet.
The WIFI communication carries multiple communication data through time division multiplexing, and the debug terminal 200 needs to encapsulate a debug instruction into a data packet with a specified preset format, so that the communication chip 100 can accurately obtain the debug instruction without affecting other functions being executed by the communication chip 100.
In an implementation manner of this embodiment, the debug packet in the preset format may include a packet of a vector specific content format frame specified by the 802.11 protocol, so as to be distinguished from a packet sent by another data service.
In another implementation manner of this embodiment, the debug packet in the preset format may also include a packet with a special Check Sequence (FCS), such as a packet with an inverted FCS, so as to be distinguished from packets sent by other data services.
It should be noted that the setting manners of the debug packets in the preset format are only two preferred embodiments provided in this embodiment, and in other embodiments of this embodiment, other setting manners of the packets that can be distinguished from other data services may also be adopted.
In step S120, the communication chip 100 receives the wireless signal through the wireless communication module 140, and detects and obtains the debug data packet sent by the debug terminal 200.
The communication chip 100 receives data packets sent by the debugging terminal 200 through wireless signals, and screens out the debugging data packets in the preset format from the received data packets.
Step S130, the communication chip 100 analyzes the debug data packet to obtain a debug instruction.
The communication chip 100 parses the debug packet, and obtains the debug instruction included in the debug packet. In this embodiment, the debug instruction may be to read hardware information of a specified location or to change the hardware information of the specified location.
In step S140, the communication chip 100 reads the hardware information of the debug instruction through the debug control module 130, generates the read hardware information into a feedback data packet, and wirelessly transmits the feedback data packet, or modifies the hardware information of the debug instruction.
When the debug instruction is to read the hardware information at a specific location, the debug control module 130 reads the hardware information of the communication chip 100 according to the data location specified by the debug instruction, where the hardware information may include, but is not limited to, a value of a register, a value of a data point in a memory, or a value of a preset observation signal point.
The debug control module 130 generates the read hardware information record into a feedback data packet, and wirelessly transmits the feedback data packet through the wireless communication module 140, so that the debug terminal 200 can receive the feedback data packet.
When the debug instruction is to change the hardware information at a specific location, the debug control module 130 obtains the verification information, the target data address information, and the data value in the debug instruction, and verifies the verification information, so as to ensure that only the debug instruction holding the credential related to the communication chip 100 is allowed to change the hardware information.
After verifying the verification information, the debug control module 130 writes the data value to the location indicated by the target data address information, where the target data address may be an address of a register or an address in the memory 120.
Step S150, the debugging terminal 200 obtains the feedback data packet sent by the communication chip 100, and analyzes and displays the hardware information in the feedback data packet.
Specifically, the debugging terminal 200 acquires the feedback data packet in the wireless signal through a sniffer communication software debugging tool, and analyzes and displays the hardware information in the feedback data packet.
The sniffer communication software debugging tool is a general wireless signal packet capture tool, and in this embodiment, the debugging terminal 200 may interface with the sniffer communication software debugging tool to obtain the feedback packet in the wireless signal. After receiving the feedback data packet, the debugging terminal 200 directly displays the original content of the feedback data packet or develops a corresponding interpreter to restore debugging information.
Based on the above design, for the communication chip 100, the wireless communication module 140 is multiplexed to receive the debugging data packet, and the debugging control module 130 changes or reads hardware information according to the debugging instruction, so that a small amount of internal circuits are added without adding precious pins, and wireless debugging is realized. For the debugging terminal 200, observation and debugging of the internal state of the equipment are realized by multiplexing a sniffer communication software debugging tool without extra wiring.

Step S210, receiving the wireless signal through the wireless communication module 140, and detecting and acquiring the debug data packet sent by the debug terminal 200.
Step S220, analyzing the debugging data packet to obtain a debugging instruction.
Step S230, reading the hardware information of the debugging instruction through the debugging control module 130, generating the read hardware information into a feedback data packet and sending the feedback data packet wirelessly, or modifying the hardware information of the debugging instruction through the debugging control module 130.
Specifically, please refer to step S120, step S130, and step S140 of this embodiment for detailed steps in step S210, step S220, and step S230, which are not described herein again.
Referring to fig. 6, the present embodiment further provides a hardware wireless debugging apparatus 110 of the communication chip 100 shown in fig. 1, the apparatus includes:
