Embodiment 1

[0047] The embodiment of the present invention provides a storage chip SUBROM detection method, such as figure 1 As shown, the method includes the following steps:

[0048] S101: When a detection start instruction is received, write a first character string into the SUBROM.

[0049] Wherein, the detection start instruction is an instruction for starting detection. When receiving the instruction to start the detection, write the first character string into the storage chip SUBROM to be detected. In an implementation manner, the detection start instruction may be triggered by a user (also known as a detection person) according to a detection requirement. For example, after the user connects the SUBROM to the SUBROM detector, the user clicks or presses a test control switch provided by the SUBROM detector to trigger a detection start instruction. Users can control the startup time of SUBROM according to their own schedule. For example, when the user is tired, he can close his...

Embodiment 2

[0083] An embodiment of the present invention provides a memory chip SUBROM detector, such as figure 2 As shown, it includes: control unit main body 31, qualified feedback module 32, unqualified feedback module 33, test control switch S1; the control unit main body includes test input pins, first output pins, second output pins, read and write data pin. The test input pin can be the K64 pin of the control unit main body 31, the first output pin can be the K23 pin of the control unit main body, the second output pin can be the K22 pin of the control unit main body 31, and the read and write data reference The pin can be the K67 pin of the main body 31 of the control unit. The control unit body 31 may be an automatic transmission control unit (Transmission Control Unit, TCU).

[0084] The pin K64 of the control unit main body 31 is connected to the test control switch S1, and the test control switch S1 is used for inputting a detection start instruction. The test control swi...

Embodiment 3

[0095] An electronic device provided by an embodiment of the present invention, such as image 3 As shown, the electronic device 40 includes a processor 41 and a memory 42, the memory stores a computer program that can run on the processor, and the processor implements the method provided by the first embodiment above when executing the computer program A step of.

[0096] see image 3 , the electronic device further includes: a bus 44 and a communication interface 43 , the processor 41 , the communication interface 43 and the memory 42 are connected through the bus 44 . The processor 41 is used to execute executable modules, such as computer programs, stored in the memory 42 .

[0097] Wherein, the memory 42 may include a high-speed random access memory (RAM, Random Access Memory), and may also include a non-volatile memory (non-volatile memory), such as at least one disk memory. The communication connection between the system network element and at least one other network...

Abstract

The invention provides a storage chip SUBROM detection method and a detector, and relates to the technical field of storage chip detection. The method comprises the steps of when a detection startinginstruction is received, writing a first character string into an SUBROM; executing the reading operation of the first character string on the SUBROM according to a preset time interval to obtain a second character string; determining a detection result according to the first character string and the second character string; and outputting the detection result according to the output pin corresponding to the detection result. According to the invention, the detection result of the SUBROM is determined by comparing character strings written in and read from the SUBROM; and the detection resultis output, so that the detection result is more visual, rapid and accurate detection on the SUBROM qualification is realized, the method can be applied to batch detection on the SUBROM by a productionline, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of memory chip detection, in particular to a memory chip SUBROM detection method and a detector. Background technique [0002] The memory chip (SUBROM) is a kind of memory chip installed on the automatic transmission of the car, which is used as off-line data storage. The automotive automatic transmission control system precisely controls the automatic transmission by calling the off-line calibration data in the SUBROM. SUBROM data reading is an important link in the automatic transmission control system, and the accuracy of SUBROM data transmission determines the reliability and safety of the automatic transmission. [0003] Therefore, before installing the SUBROM into the automatic transmission of an automobile, it is necessary to test the products provided by the SUBROM manufacturer. At present, the manual detection method is used, and the detection efficiency is low. How to improve the detection efficie...
