Description
Technical Field

Background
With the development of optical communication technology, optical module technology as a key node in the construction of optical communication networks is increasingly refined, and the packaging form of optical modules is also developed towards the direction of smaller volume at the same rate and higher rate at the same volume.
Due to the increase of the integration level of the optical module, in the technical field of the optical module, a Microcontroller Unit (MCU) is increasingly adopted for the optical module with a digital diagnostic function. The method mainly monitors parameters such as temperature, power supply voltage, bias current, transmitting and receiving optical power and the like of the optical module with a digital diagnosis and detection function in real time, judges the communication working condition of the optical module by analyzing a digital measurement result, and can establish a corresponding communication link for register configuration in an EML laser driver by programming a Micro Controller Unit (MCU) chip.
In order to meet the requirements of various systems, the variety of optical modules will be increased, and the performance will also be higher. The selection of the microcontroller unit MCU chip in the current optical module is roughly divided into: ATEML, Silabs, ADI, and ST, etc. Generally, one of two interfaces is used for downloading and debugging the firmware program of the MCU chip of the MCU, one is a JTAG (joint test action group) protocol interface, and the other is a Serial Wire Debug (SWD) interface. As the package size of the optical module becomes smaller and smaller, no matter which download and debug interface is selected, the optical module faces challenges.
At present, there are two general methods for downloading and debugging a firmware program of an MCU chip of a microcontroller unit, the first method is that a Bootloader program is solidified inside an MCU, and a firmware of an optical module can be downloaded through a communication interface (a serial port or I2C, etc.) according to a manufacturer-specific protocol; the second method is to make several holes or pads on the PCB, and after a Serial Wire Debug (SWD) interface or a Joint Test Action Group (JTAG) protocol interface is connected and flying, a firmware program can be programmed, and a program can also be debugged online.

As shown in fig. 1, an embodiment of the present invention provides an apparatus for downloading and debugging an optical module firmware code, including an optical module PCB300 and an optical module test board 100, where the optical module test board 100 is provided with an optical module electrical interface socket 110, and pins of the optical module electrical interface socket 110 are respectively led out of a communication interface 120 and a code downloading and debugging interface 130; an optical module programming interface 320 for connecting with the optical module electrical interface socket 110 during programming of codes is arranged at one end of the optical module PCB300, and when the optical module PCB300 inserts the optical module programming interface 320 into the optical module electrical interface socket 110, the optical module programming interface 320 is connected with the communication interface 120 and the code downloading and debugging interface 130 through pins inside the optical module PCB300, so as to perform communication and code downloading and debugging on the optical module PCB 300.
Through the above design, the pins corresponding to the optical module electrical interface socket 110 are connected to the code downloading and debugging interface 130, and the optical module programming interface 320 is inserted into the optical module electrical interface socket 110, so that the optical module can be conveniently subjected to firmware downloading or online debugging operation through the code downloading and debugging interface 130. For convenience of debugging, in the above design, the communication interface 120 is also connected to the optical module programming interface 320 through the optical module electrical interface socket 110, so that the pins corresponding to the optical module electrical interface socket 110 are connected to the communication interface 120, and thus the communication interface 120 is communicated with the optical module programming interface 320, and thus, in the debugging process, the operating condition of the optical module can be known through the communication between the communication interface 120 and the optical module. Through the arrangement, the firmware code downloading and debugging operation of the optical module can be completed without flying wires, so that the burning reliability of the optical module firmware is greatly improved, and the production efficiency of the optical module can also be improved.
As shown in fig. 2, in the preferred embodiment, taking QSFP28 optical module PCB as an example, the optical module programming interface 320 of the PCB includes a code download and debug pin 323 and a communication pin 324. When the optical module programming interface 320 is inserted into the optical module electrical interface socket 110, the code downloading and debugging pin 323 is connected with the code downloading and debugging interface 130 through a corresponding pin of the optical module electrical interface socket 110, so that the singlechip codes can be downloaded or debugged online through the code downloading and debugging interface 130 after connection; the communication pin 324 is connected to the communication interface 120 through a corresponding pin of the optical module electrical interface socket 110, and can send a command or obtain an operating state of an optical module through the communication interface 120, so as to debug a single chip microcomputer code on line better.
In the preferred embodiment, six gold fingers are led out from the optical module programming interface 320 of the QSFP28 optical module PCB, wherein the code downloading and debugging pin 323 adopts an SWD pin and occupies two gold fingers, and the two gold fingers are an SWDIO pin and an SWDCLK pin respectively; the communication pin 324 adopts an I2C pin and occupies two gold fingers, which are an SCL pin and an SDA pin. The two gold fingers are a common ground pin 321 and a power supply pin 322, respectively, wherein the common ground pin 321 is a GND pin, and the common ground pin 321 is connected to a corresponding ground pin in the optical module electrical interface socket 110, so that the optical module PCB300 and the optical module test board 100 are grounded together; the power supply pin 322 is a VCC pin, and the power supply pin 322 is connected to a corresponding power connection pin in the optical module electrical interface socket 110 to supply power to the optical module PCB 300.

In the preferred embodiment, the optical module PCB300 is further provided with an electrical interface 310 at the other end opposite to the optical module programming interface 320, and the package of the optical module programming interface 320 is consistent with the package of the electrical interface 310. In the embodiment, one end where the electrical interface 310 is located is defined as a head, and one end where the optical module programming interface 320 is located is defined as a tail, and in the specific use process of the optical module PCB300, if the optical module PCB is normally used, the electrical interface 310 of the head is inserted into the corresponding optical module electrical interface socket 110, and the optical module electrical interface socket can be used; if the firmware code needs to be downloaded and debugged, the optical module programming interface 320 at the tail part is inserted into the corresponding optical module electrical interface socket 110, and the optical module can be used.
It should be noted that, in the preferred embodiment, after the optical module test board 100 is manufactured, the positions of the corresponding code download and debug pins 323 of the optical module programming interface 320 and the gold fingers of the communication pins 324 are already fixed. The positions of the common ground pin 321 (in this embodiment, the GND pin) and the power supply pin 322 (in this embodiment, the VCC pin) may be led out from the front side or the ground of the PCB according to the requirement of the PCB layout, but it is necessary to ensure that the positions of the common ground pin 321 and the power supply pin correspond to the positions of the GND pin and the VCC pin of the electrical interface 310, otherwise, the PCB cannot be normally powered.
As shown in fig. 3, a PC200 may be further added in the embodiment, and after the PC200 is added, the PC200 is connected to the optical module test board 100, so as to display and control the optical module test board 100 and the optical module PCB300 on the PC 200.

In another embodiment, as shown in FIG. 4, a QSFP-DD optical module PCB is taken as an example. Because the electrical interface 310 of the QSFP-DD optical module PCB is relatively large, if the optical module programming interface 320 uses the original electrical interface 310, a lot of space is inevitably wasted. In order to save space, the optical module programming interface 320 uses the same electrical interface package as the QSFP28 optical module PCB in the above embodiment, and the same six gold fingers are also led out, so that the optical module firmware code downloading and debugging of the embodiment can be realized by the same method as the above embodiment.
In summary, the present embodiment skillfully defines the tail of the optical module PCB as the programming interface, and the programming interface is packaged the same as the electrical interface (gold finger) at the head of the optical module PCB, so that the programming interface can be connected to the electrical interface socket of the optical module as if the optical module is plugged. The corresponding pins of the electrical interface socket of the optical module are connected with the code downloading interface, so that the firmware can be conveniently downloaded to the optical module through the code downloading interface or the online debugging can be conveniently carried out. In order to facilitate debugging, a communication pin of a single chip Microcomputer (MCU) is also connected to the programming interface, and a pin corresponding to an electrical interface socket of the optical module is connected with the communication interface, so that the running condition of the optical module can be known through communication between the communication interface and the optical module in the debugging process. By the method, flying wires are not needed, so that the programming reliability of the optical module firmware is greatly improved, and the production efficiency of the optical module can also be improved. In addition, for the optical module PCB with a larger electrical interface, the interface can be programmed by adopting a smaller volume, and the beneficial effect of saving space can be achieved only by ensuring the consistent setting of the golden fingers.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
