Description

Technical Field

[0001] This invention relates to the field of computer hardware technology, and in particular to a chip firmware burning status detection device, method, equipment, and storage medium. Background Technology

[0002] During server manufacturing, a large number of chips need to be firmware-programmed to achieve their preset functions. However, whether the firmware is programmed manually using a fixture or using a dedicated machine, programming failures can occur.

[0003] Programming failures can occur in several ways: 1) Missed programming, meaning the chip was not programmed; 2) Incorrect programming version, causing functional problems; 3) In some cases of programming failure, the programming software may still display "programming successful," leading to misleading results. These failed programming chips, undetected, will continue the production process and be soldered onto the PCB. This ultimately causes problems such as the device failing to power on or malfunctioning in some areas. Furthermore, because they are already soldered onto the board, reprogramming requires rework, significantly delaying production.

[0004] In existing technologies, some chips support subsequent updates via I2C pins, but this does not allow for a determination of whether the programming was successful before the chips enter the production line. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a chip firmware burning status detection device, method, apparatus, and storage medium, which can immediately detect and verify whether the burning was successful after the burning operation is performed in the factory. The specific solution is as follows:

[0006] The first aspect of this application provides a chip firmware burning status detection device, comprising:

[0007] Power supply lines and intermediate signal transmission circuits;

[0008] A chip test base connected to the power supply line for placing the chip to be tested that has undergone firmware burning.

[0009] A power stage chip connected to the power supply line and connected to the chip under test on the chip test base via the intermediate signal transmission circuit is used to acquire the pulse width modulation signal output by the chip under test through the intermediate signal transmission circuit when the power supply line is in a powered state, and generate a corresponding voltage value under the control of the pulse width modulation signal, so as to determine whether the firmware burning operation is successful based on the voltage value.

[0010] Optionally, the device further includes:

[0011] Signal transmission lines;

[0012] The control chip, which is connected to the chip under test on the chip test base via the signal transmission line, is used to output a control signal to the chip under test via the signal transmission line when the power supply line is in a powered state, so as to use the control signal to control the chip under test accordingly.

[0013] Optionally, the control signal is an initialization signal used to perform initialization control on the chip under test.

[0014] Optionally, the control signal is an enable signal used to enable the chip under test.

[0015] Optionally, the device further includes:

[0016] Information transmission line used to connect the control chip and the chip under test on the chip test base;

[0017] Correspondingly, the control chip is also used to obtain the burning version information output by the chip under test through the information transmission line, and to determine whether the firmware burning version is correct based on the burning version information.

[0018] Optionally, the information transmission line is an I2C bus.

[0019] A second aspect of this application provides a method for detecting the firmware burning status of a chip, applied to a chip firmware burning status detection device. The device includes a power supply line, an intermediate signal transmission circuit, a chip test base connected to the power supply line for placing a chip under test that has undergone firmware burning, and a power stage chip connected to the power supply line and connected to the chip under test on the chip test base via the intermediate signal transmission circuit. The method includes:

[0020] When the power supply line is in a power supply state, the power stage chip uses the intermediate signal transmission circuit to obtain the pulse width modulation signal output by the chip under test, and generates a corresponding voltage value under the control of the pulse width modulation signal.

[0021] The success of the firmware burning operation is determined based on the voltage value.

[0022] Optionally, determining whether the firmware burning operation was successful based on the voltage value includes:

[0023] Determine whether the voltage value is within the reference voltage range determined based on the power supply voltage of the power supply line;

[0024] If the voltage value is within the reference voltage range, then the firmware burning is considered successful.

[0025] A third aspect of this application provides an electronic device, which includes a processing unit and a storage unit; wherein the storage unit is used to store a computer program, which is loaded and executed by the processing unit to implement the aforementioned chip firmware burning status detection method.

[0026] A fourth aspect of this application provides a computer-readable storage medium, wherein the computer program, when executed by a processing unit, implements the aforementioned chip firmware burning status detection method.

[0027] This application provides a chip firmware burning status detection device comprising a power supply line and an intermediate signal transmission circuit; a chip test base connected to the power supply line for placing a chip under test that has undergone firmware burning; and a power stage chip connected to the power supply line and connected to the chip under test on the chip test base via the intermediate signal transmission circuit. When the power supply line is powered on, the power stage chip acquires the pulse width modulation signal output by the chip under test via the intermediate signal transmission circuit and generates a corresponding voltage value under the control of the pulse width modulation signal. Based on this voltage value, the success of the firmware burning operation can be determined. Therefore, by measuring the corresponding voltage value generated by the power stage chip under the control of the pulse width modulation signal, the success of the firmware burning operation can be determined. This allows for immediate verification of successful burning after the factory burning process, avoiding situations where problems are only discovered after production is complete, thus significantly saving production time.

[0036] In existing technologies, some chips support subsequent updates via I2C pins, but this does not allow for verification of successful programming before the chips enter the production line. This invention will introduce a...

[0037] See Figure 1As shown, this embodiment of the invention discloses a chip firmware burning status detection device, including: a power supply line 1 and an intermediate signal transmission circuit 7; a chip test base 2 connected to the power supply line 1 for placing a chip 6 to be tested that has undergone firmware burning; and a power stage chip 8 connected to the power supply line 1 and connected to the chip 6 to be tested on the chip test base 2 via the intermediate signal transmission circuit 7. The power stage chip 8 is used to acquire the pulse width modulation signal currently output by the chip 6 to be tested via the intermediate signal transmission circuit 7 when the power supply line 1 is in a powered state, and to generate a corresponding voltage value under the control of the pulse width modulation signal, so as to determine whether the firmware burning operation was successful based on the voltage value. The intermediate signal transmission circuit 7, as shown... Figure 2 As shown. In this way, the success of the programming can be verified immediately after it is performed in the factory, thus avoiding the situation where problems are only discovered after production is completed, and greatly saving the time cost of production line operations.

[0038] In this embodiment, the chip firmware burning status detection device further includes: a signal transmission line 4; and a control chip 3 connected to the chip under test 6 on the chip test base 2 via the signal transmission line 4, which is used to output a control signal to the chip under test 6 via the signal transmission line 4 when the power supply line 1 is in the power supply state, so as to use the control signal to perform corresponding control on the chip under test 6.

[0039] In this embodiment, the control signal is an initialization signal for initializing the chip 6 under test and an enable signal for enabling the chip 6 under test.

[0040] In this embodiment, the chip firmware burning status detection device further includes: an information transmission line 5 for connecting the control chip and the chip under test on the chip test base; correspondingly, the control chip 3 is also used to obtain the burning version information output by the chip under test 6 through the information transmission line 5, and determine whether the firmware burning version is correct based on the burning version information. The information transmission line 5 is an I2C bus. In this way, the firmware burning version can be checked and verified immediately after burning in the factory, thus avoiding the situation where problems are only discovered after production is completed on the production line, thereby greatly saving the time cost of factory production line production.

[0041] As can be seen, this embodiment provides a chip firmware burning status detection device comprising a power supply line 1 and an intermediate signal transmission circuit 7; a chip test base 2 connected to the power supply line 1 for placing a chip 6 to be tested that has undergone firmware burning; and a power stage chip 8 connected to the power supply line 1 and connected to the chip 6 to be tested on the chip test base 2 via the intermediate signal transmission circuit 7. This power stage chip 8, when the power supply line 1 is powered on, acquires the pulse width modulation signal output by the chip 6 to be tested via the intermediate signal transmission circuit 7, and generates a corresponding voltage value under the control of the pulse width modulation signal, so as to determine whether the firmware burning operation was successful based on the voltage value. Therefore, by measuring the corresponding voltage value generated by the power stage chip 7 under the control of the pulse width modulation signal, the success of the firmware burning operation is determined based on the voltage value. This allows for immediate verification of successful burning after the factory burning process, avoiding situations where problems are only discovered after production is completed, thus significantly saving production time costs.

[0042] See Figure 3 As shown, this invention discloses a chip firmware burning status detection method, applied to a chip firmware burning status detection device. The chip firmware burning status detection device includes a power supply line, an intermediate signal transmission circuit, a chip test base connected to the power supply line for placing a chip to be tested that has undergone firmware burning, and a power stage chip connected to the power supply line and connected to the chip to be tested on the chip test base via the intermediate signal transmission circuit; comprising:

[0043] Step S11: When the power supply line is in the power supply state, the power stage chip uses the intermediate signal transmission circuit to obtain the pulse width modulation signal output by the chip under test, and generates the corresponding voltage value under the control of the pulse width modulation signal.

[0044] In this embodiment, when the power supply circuit is in the power supply state, the chip under test controls the power stage chip through control signals such as pulse width modulation signals and feedback signals. Since the method of measuring the voltage between the chip under test is relatively complicated, the power stage chip can be controlled through control signals such as pulse width modulation signals and feedback signals, and then the voltage output by the power stage chip can be measured. In this way, it is only necessary to measure the voltage output by the power stage chip to determine whether the chip under test has been successfully programmed.

[0045] Step S12: Determine whether the voltage value is within the reference voltage range determined based on the power supply voltage of the power supply line.

[0046] In this embodiment, since the power supply circuit has a certain influence on the output voltage of the chip under test and the power stage chip, the influence of the power supply circuit needs to be considered when determining whether the firmware burning operation is successful based on the voltage value. Therefore, it is necessary to determine whether the voltage value is within the reference voltage range determined based on the power supply voltage of the power supply line. It is understood that when the power supply voltage changes, the reference voltage range will also change accordingly. This avoids errors in determining the success of the firmware burning operation due to changes in the power stage chip's output voltage caused by the power supply voltage.

[0047] Step S13: If the voltage value is within the reference voltage range, then the firmware burning is confirmed to be successful.

[0048] In this embodiment, the operation of determining successful firmware burning further includes: using a control chip to obtain the burning version information output by the chip under test through the information transmission line, and determining whether the firmware burning version is correct based on the burning version information. The control chip controls the chip under test through control signals such as initialization signals and enable signals, and then communicates with the chip under test through the I2C bus. By obtaining the burning version information output by the chip under test, the control chip prints and displays the burning version information. The correctness of the firmware burning version is determined based on the burning version information. In this way, it is possible to avoid the situation where the function of the chip under test is malfunctioning due to different burning version information.

[0049] As can be seen, this embodiment provides a method for detecting the firmware burning status. When the power supply line is powered on, the power stage chip in the firmware burning status detection device uses the intermediate signal transmission circuit in the device to acquire the pulse width modulation signal output by the chip under test, and generates a corresponding voltage value under the control of the pulse width modulation signal. Based on the voltage value, it is determined whether the firmware burning operation was successful. Therefore, by measuring the corresponding voltage value generated by the power stage chip under the control of the pulse width modulation signal, the success of the firmware burning operation is determined. This allows for immediate verification of successful burning after the factory burning process, avoiding situations where problems are only discovered after production is complete, thus significantly saving production time.
