XVC768102 3BHB007211R102 puts the same software on two similar but different hardware platforms. Compare two different versions of software to run on the same hardware platform; Compare the phenomenon of running the same software on the same batch but different hardware platforms. For some problems which are not very hidden, the comparative method can usually get good results.
3) Decomposition method: When it comes to problems that are complicated to analyze and may have many factors, the problem can be divided into several small problems to test and diagnose, such as writing several separate small test programs to check and test various possible factors, and then make scientific judgments according to these test results.
4) Hardware and software combination: This method requires a certain amount of inspiration and savvy. For example, in example 5 above, during the test process, the state of the hardware can be temporarily changed without damaging the hardware (such as the short circuit of the data line and the clock line in this example) to see whether the problem will change. If so, do more similar tests to find out the change rule and key factors, and then analyze and solve. In the underlying software development, special attention should be paid to the software programming of hardware modules with strict timing requirements, once the timing of the program has a problem, and this part of the software has been integrated with other system software, then this software is difficult to find out the problem for others to check.
5) Diagnosis and troubleshooting should be based on a large number of experiments, and should be more hands-on, not only know speculation, but also unwilling to actual operation, and it is called “good at thinking and analysis”. Embedded system development is a very practical science, we need to summarize the objective laws of things in practice, so as to better understand and use them, so that they better work according to our intentions.
6) Embedded system development and debugging requires developers to have a rigorous and meticulous work attitude, never let go of any trace found in the debugging process, because it is likely to be the key to open Pandora’s treasure box.
7) We should have a realistic work style, we should have the spirit and courage to doubt everything, we should respect the authority and the scientific and technological achievements of predecessors, but when there are contradictions, we should believe the experimental results, so that science will progress.
8) We should dare to challenge ourselves, put aside habitual thinking and stereotypes, broaden our thinking and analyze problems from multiple perspectives.
9) Embedded system development, especially the development of underlying software and operating system kernel, is a difficult and challenging task because it needs to deal with both software and hardware. Even if we have done very well in all aspects and considered very carefully, the target system may still play some small jokes with us, we often encounter a very small problem that bothers us for several days or even weeks, during which we may not be able to sleep at night, so the underlying software developers of embedded systems should not only have a peaceful mind, And have a certain amount of patience and perseverance, but also have the courage and confidence to overcome all difficulties! As long as we do it well enough, the process of solving a specific problem may have some chance, but we will eventually remove all obstacles!
