Description
Technical Field
The invention relates to production test of an Internet of things module, in particular to a method for switching a plurality of production test firmware in the production process of the Internet of things module.
Background
Today in the internet of things era, more and more internet of things devices come out, and with the help of various different internet of things IOT chips, the interconnection of everything is realized, so that great convenience is brought to the work and the life of people. Different manufacturers have different detection methods for IOT chips, so that the requirement that a plurality of production test firmware are required to be simultaneously burned into a flash arises.
In the prior art, a plurality of production test firmware needs to be burned for a plurality of times, and a plurality of production processes need to be adopted for different production test firmware to carry out production test, so that the production efficiency is reduced.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the method for switching the production test firmware in the production process of the Internet of things module is provided, and the production test firmware can be switched back and forth in one production process and can be subjected to production test.
The technical scheme adopted by the invention for solving the technical problems is as follows:
the method for switching a plurality of production test firmware in the production process of the Internet of things module comprises the following steps:
a. combining a plurality of production test firmware into one firmware, and burning the firmware onto a flash of the Internet of things module through a burning tool;
b. operating the Internet of things module, and carrying out production test on a production test firmware through a production test tool;
c. after the production test is finished, switching to a new production test firmware for the production test;
d. after the new production test firmware is tested, copying the next production test firmware in the flash to the position of the firmware of which the production test is finished at the beginning;
e. the Internet of things module is restarted, and the next production test firmware is operated to continue the production test;
f. and c-e is circulated, so that a plurality of production test firmware can be switched back and forth in one production flow and the production test can be carried out.
As a further optimization, in step a, each production test firmware is provided with a function of copying to a specific address through flash reading and writing.
The firmware can be copied to a flash specific address through a flash read-write copying function in the firmware, so that free switching between the firmware is convenient to realize.
As a further optimization, in the step a, firstly, a plurality of production test firmware are merged into one firmware through a Windows tool capable of merging a plurality of production test firmware, and then the merged firmware is burned onto the flash at one time through the Windows tool capable of burning the firmware onto the flash of the internet of things module.
Multiple burning can be avoided by combining a plurality of firmware and burning the firmware on the Internet of things module flash at one time, so that the production efficiency is improved.
The beneficial effects of the invention are:
by adding a flash read-write copy function in the firmware, in addition, combining a plurality of production test firmware into one firmware, and burning the firmware onto the flash of the Internet of things module through a burning tool; in the production flow, clearing the position of the firmware which has finished the production test flow, and then copying the new firmware of the specific address to the cleared position; therefore, the purposes that a plurality of production test firmware are switched back and forth in one production process and production test is carried out are achieved, and compared with the traditional method of burning for multiple times, the production efficiency is greatly improved by adopting the multiple production processes.

Fig. 1 is a flowchart of a method for switching a plurality of production test firmware in a production process of an internet of things module in an embodiment.
Detailed Description
The invention aims to provide a method for switching a plurality of production test firmware in the production flow of an Internet of things module, which realizes the switching of the plurality of production test firmware back and forth in one production flow and carries out production test. The core idea is as follows: when the production test firmware is developed, a function of copying to a specific address through flash reading and writing is added into the firmware, after one production test firmware is tested, the operation is switched to another production test firmware through an AT instruction, after the production test is completed on a new production test firmware, the other production test firmware is copied to the position of the previous production test firmware through flash reading and writing, then the previous production test firmware is switched to start, and the switching operation of a plurality of production test firmware can be completed in a reciprocating manner.
In a specific implementation, to implement the multiple production test firmware switching scheme of the present invention, the following support parts are required:
1) An Internet of things chip with a certain size of flash is built in;
2) A plurality of production test firmware with flash read-write copy function;
3) A Windows tool capable of incorporating multiple production test firmware;
4) Windows tools capable of production testing;
5) The Windows tool can burn firmware to the flash of the Internet of things module.
The method comprises the following implementation steps:
a. combining a plurality of production test firmware into one firmware, and burning the firmware onto the flash of the Internet of things module through a burning tool;
b. running the Internet of things module, and performing production test on a production test firmware through a production test tool;
c. after the production test is finished, switching to a new production test firmware for the production test;
d. after the new production test firmware is tested, copying the next production test firmware in the flash to the position of the firmware which has been tested at the beginning;
e. the Internet of things module is restarted, and the next production test firmware is operated to continue the production test;
f. and c-e is circulated, so that a plurality of production test firmware can be switched back and forth in one production flow and the production test can be carried out.

2. combining a plurality of firmware with copy function into one firmware through a synthesis tool, and burning the synthesized firmware into the flash of the Internet of things module through a Windows burning tool;
3. the Internet of things module is powered on, runs in a first firmware Ota1.Bin, starts to perform production test through a Windows production test tool, and is switched to another firmware Ota2.Bin after the test is finished;
4. after the ota2.Bin production test is completed, a copy function is invoked, the ota3.Bin is copied to the position of the ota1.Bin, and the operation is switched to the ota3. Bin;
5. after the Ota3.Bin production test is completed, calling a copy function, copying the next firmware Ota4.Bin to the position of the last firmware Ota2.Bin which has completed the test, switching to the position of Ota2.Bin to operate Ota4.Bin and complete the production test;
