[0044] Please refer to Figures 1 to 5 the specific embodiments shown, among which, please refer to Figures 1 to 3 shown, the present invention discloses a method for SSD firmware download test, including the following steps:

[0045] S1. Obtain the firmware sent by the host;

[0046] Among them, before step S1, it further includes: the host obtains the SSD hardware information, sends the firmware according to the SSD hardware information, and transmits the firmware through the high-speed PCIE interface.

[0047] Among them, in this embodiment, the host obtains the SSD hardware information through the USB signal, and then sends the firmware according to the SSD hardware information (such as: model, etc.). The firmware data stream is converted from USB to PCIE signal, and the PCIE signal is transmitted through PCIE and can be directly received by the SSD.

[0048] S2. After receiving the firmware, restart the SSD power supply;

[0049] Among them, in step S2, when the firmware is received, the SSD power supply is turned off, and after 30 - 150 ms, the SSD power supply is turned on again to achieve restart.

[0050] Among them, in this embodiment, when the SSD finishes receiving the firmware, it will prompt the MCU. When the MCU determines that the firmware download is complete, it immediately controls the SSD power to turn off, and then turns on the SSD power again after 100 ms, realizing the cold start of the SSD.

[0051] S3, perform a test of a set type on the SSD;

[0052] Among them, the test of the set type includes a cyclic power-on and power-off test, an abnormal power-off test, or a cyclic erase, write, and read stress test.

[0053] Among them, after the SSD power is restarted, the SSD test can perform various types of tests, such as a cyclic power-on and power-off test, an abnormal power-off test, a cyclic erase, write, and read stress test, etc.

[0054] For the cyclic power-on and power-off test, the power supply can be controlled by the MCU to switch between power-on and power-off at specific time intervals (for example: 150 ms); after a period of cyclic testing, record the cyclic test, the number of abnormal occurrences, the type of abnormality, etc.

[0055] For the abnormal power-off test, the test can simulate whether data loss and hard disk abnormalities will occur when the power supply accidentally drops during the data read and write process.

[0056] For the cyclic erase, write, and read stress test, the test simulates working for a long time under specific temperature and humidity conditions under a full load condition to check the hard disk aging situation and the probability of data abnormalities.

[0057] S4, obtain the test results and upload the test results to the host.

[0058] Among them, when the SSD completes a certain type of test, it will notify the MCU. The MCU actively obtains the test result data packet stored inside the SSD after aging, then collects the SSD data packets of the entire array board, and then uploads them to the host to complete the entire process. Among them, the test results include the number of abnormalities, the type of abnormality, whether data loss and hard disk abnormalities occur, the hard disk aging situation, and the probability of data abnormalities, etc.

[0059] Among them, as Figures 2 to 3 shown, the device mainly consists of three parts, including a host, an adapter board, and a PCIE interface array board. Among them, the host only needs to use a general computer with a USB interface. All power control, firmware download, aging test, and test result acquisition on the array can be directly implemented through the computer, and the data is uploaded to the server. The functional modules other than the host are as follows:

[0060] Adapter board: It plays the role of being compatible with multiple PCIE array boards, connects the power supply, the host USB signal, etc., and converts them to a gold finger connector through PCB traces; the gold fingers are defined in a specific order to complete the basis for compatibility with each array board.

[0061] PCIE Array Board: It functions to convert all input data transmission forms, execute aging, and obtain test results; data such as firmware is input from the USB signal, switched to the specified communication path via the HUB; the USB signal is then converted into PCIE communication data by the USB to PCIE chip and directly reaches the PCIE device under test (such as an SSD). The MCU module circuit realizes the switching control of the USB HUB, the power control of the device under test during the aging test process, and converts the aging results obtained through the serial port into USB and uploads them to the host.

[0062] Among them, the adapter board introduces USB2.0 / USB3.0 signals from the host through a standard USB Type A interface, without processing, and is directly connected to the gold finger connector; in the PCIE array board, the MCU plays a role in power control, HUB switching, and serial port result capture; in the PCIE array board, the function of power control is also one of the purposes of realizing integration. There is no need to manually power on again or plug and unplug the device under test. When the firmware download is completed, the power can be controlled to achieve power on and off again, and the restart of the device under test can be completed; in the PCIE array board, the application of the USB HUB can expand one-channel USB3.0 signals into four-channel USB3.0, which is beneficial to communicating with four PCIE devices mainly through one USB, facilitating batch operations in production and greatly improving efficiency; in the PCIE array board, taking advantage of the long transmission distance, signal stability, and fast transmission rate of the USB signal, the system processes the USB signal after long-distance transmission and converts it into a PCIE signal, which can directly communicate with the PCIE device under test; this device is not limited to a single PCIE device under test. The PCIE device can be compatible with M.2, standard PCIE, or custom PCIE interfaces, etc. Two or more array boards can be designed, with different PCIE interfaces defined, and can be directly used by connecting to the connection board according to the usage requirements.

[0063] Among them, as Figure 3 shown, in order to apply the system to PCIE devices with different interfaces at the same time, and different devices can share the same host and connection board platform, facilitating the replacement of the device under test on the array board, the pin number, signal, order, and power supply voltage of the gold finger are hereby defined.

[0064] The present invention adopts USB signal expansion, PCIE signal conversion and MCU control technologies, and can meet all the requirements of batch firmware downloading, batch testing and information collection functions for SSDs on a set of equipment, satisfying the mass production and testing requirements of SSD manufacturers, simplifying the firmware downloading and product aging testing processes during the production of current solid-state drives, and improving efficiency. It also expands a single-channel USB signal into multiple-channel USB signals and converts the USB signal into the PCIE signal required by a standard solid-state drive, so that the firmware downloading task of the solid-state drive can be completed using high-speed PCIE signals. After the firmware downloading is completed, the MCU controls the power on and off of the SSD power supply, so that the aging test of the SSD can be started. After the aging test is completed, the SSD uploads the test results to the MCU, and the MCU uploads the test results to the host computer server for analysis.

[0065] By integrating the functions of firmware downloading and testing required in the SSD production process, the present invention simplifies the process, reduces the complexity of the equipment, reduces the equipment cost of SSD manufacturers, and also uses high-speed USB for firmware downloading without the need for turnover during the production process, greatly improving the production efficiency, saving the production cost of manufacturers, reducing the product quality risk, and being able to better meet the requirements.

[0067] The compatibility connection unit 10 is used to be compatible with M.2 or PCIE interface form SSD array boards;

[0068] The acquisition unit 20 is used to acquire the firmware issued by the host;

[0069] The device restart unit 30 is used to restart the SSD power supply after receiving the firmware;

[0070] The testing unit 40 is used to perform a set type of test on the SSD;

[0071] The acquisition and upload unit 50 is used to acquire the test results and upload the test results to the host.

[0072] Among them, the device further includes: an acquisition and transmission unit, which is used for the host to acquire the SSD hardware information, issue the firmware according to the SSD hardware information, and transmit the firmware through a high-speed PCIE interface.

[0073] Among them, in the device restart unit 30, after the firmware is received, the SSD power supply is turned off, and after 30 - 150 ms, the SSD power supply is turned on again to achieve restart.

[0074] Among them, the tests of the set types include power-on and power-off cycling tests, abnormal power-off tests, or cycling erase / write / read stress tests.
