The JLINK driver is installed, and the device manager recognizes it, but the options for SW and JTAG in MDK are grayed out (this is not an issue with JLINK). Therefore, downloading and simulation cannot proceed. I tried uninstalling the JLINK driver and re-installing it, but that didn’t solve the issue, so I decided to … Read more
Simplified method for using JLINK to download programs to STM32 via JTAG interface (SW and JTAG modes)! Anyone who has used STM32 knows that there are two common methods for downloading programs: via serial port and JLINK. The serial port download method is quite similar to that of the 51, so I won’t elaborate on … Read more
There are currently three methods to program STM32: JLink, ULink, and Serial Programming, using tools such as JLink, ULink, and USB to TTL cable. ULink Programming During the installation of MDK, there will be a prompt to install the driver, which is the ULink driver. If you choose ‘Yes’, you do not need to install … Read more
The printf function is indispensable during microcontroller debugging, allowing developers to intuitively and conveniently obtain the current running status of the program. However, in chips like STM32, to achieve printf functionality, UART must be utilized. Is there a way to implement printing functionality solely with JLink? The answer is yes. ARM has adopted a new … Read more
1 Introduction UDS (Unified Diagnostic Services) is a very important diagnostic protocol in vehicles. However, unless you can access an actual project, I have not seen any open-source boards that can perform real UDS diagnostics; purely discussing theory is not very interesting. I bought a set of UDS_bootloader source code on Xianyu. Currently, I have … Read more
Detailed Usage Notes for Raspberry Pi JTAG 1. Introduction 2. Environment Setup 2.1 Hardware Connection 2.2 Software Preparation 3. Conclusion 1. Introduction Sometimes, when debugging code, hardware debugging tools are often used, and JTAG is a very good debugging tool. Below is a detailed introduction on how to use JTAG for debugging on the Raspberry … Read more
To debug ARM, you must follow the ARM debugging interface protocol, and JTAG is one of them. During simulation, IAR, KEIL, ADS, etc., all have a common debugging interface, and RDI is one of them. So how do we convert RDI to the ARM debugging protocol (JTAG)? There are two approaches: Write a service program … Read more
