Welcome FPGA engineers to join the official WeChat technical group. With the diversification of demand, the functions of FPGAs have been further enhanced. Among them, high-speed transceivers, which were originally modules found only in high-end FPGAs, have become relatively common and even essential functional modules. The 10G line rate has also shifted from being supported … 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
What is a download debugger? In simple terms, a download debugger is a device that converts commands sent from a PC (for example, via USB protocol) into a language that the MCU (which manages the MCU’s internal peripherals) can understand (such as SWD or JTAG protocol), loads code, and precisely controls execution.What is a standard? … 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
Source | STM32 The STM32L5 is based on the Cortex-M33 core, which is built on the ARMV8-M architecture and features TrustZone security technology, effectively isolating the secure and non-secure areas from the core to the entire chip system. In terms of debugging port protection, the combination of TrustZone and RDP (Read Protection) can also achieve … Read more
