1. Introduction Recently, I have developed an interest in Two-Wire CJTAG. This article mainly records some of my insights on Two-Wire CJTAG. There are many debugging interfaces, with SWD and JTAG being the most commonly used. For articles related to SWD and JTAG on this public account, you can refer to this series – “Making … Read more
1. Background and Issues The traditional JDK/JRE installation packages are large (hundreds of MB), containing many modules that are not needed by applications. For example, a small application that only depends on java.base and java.sql must carry the entire Java runtime, which not only wastes storage but also affects the distribution and startup speed of … Read more

I’m not sure how everyone prints debugging information during microcontroller development, but most likely, it’s done through serial debugging. In most cases, a serial port is reserved for debugging during board design and coding. But what if you haven’t reserved a serial port during actual development? Actually, our downloader can be used as a debugging … Read more
Recently, I switched from Windows 10 to Windows 7, so I had to reinstall various EDA software that I had previously installed. While developing a program for a Cortex-M3 core MCU using Keil, I encountered a problem: I cannot download the program using Jlink-OB. When I switched back to the previous Windows 10 system, it … Read more
Old readers should know that the Osprey has been using a homemade STlink in the lab. This time, the Osprey wants to make a J-LINK and found an article that everyone can learn from. (If I have time, I can provide ST-link and J-link firmware; these can basically be found online.) Source: https://www.jianshu.com/p/0cd3a513f1b1 The board … Read more
