Jlink driver download (Segger J-Flash ARM)Common problems:
Jlink drive problems are usually issues related to connecting hardware and software. When using Jlink, various problems may be encountered, such as failure to connect hardware, download program failure, etc. Among them, the most common problem is the unstable connection, which may be caused by the DuPont line that is too short or the interface is unstable. To solve this problem, you can consider using the longer DuPont line or use the airline to directly weld it.
In addition, Jlink drivers may have other problems, such as failure to print, program download failure, etc. These problems may be caused by various factors, such as the printing process needs to wait for mutual release release, and unreasonable hardware design. In order to solve these problems, we need to have an in -depth understanding of hardware and software and take corresponding measures. For example, you can modify the code to avoid waiting for mutual locking and release problems, redesigning hardware circuits, etc.
In short, Jlink's driving problem requires specific problems and specific analysis, and take corresponding measures to solve it. For developers, they need to have a deep understanding of hardware and software and have the ability to solve problems.
