Today, while using MDK to program, a warning appeared. Initially, I didn’t pay attention to this issue because during actual testing, the program could be programmed normally and also debugged. However, later a colleague encountered this warning repeatedly during debugging, which affected normal testing, so I decided to investigate! 01 Error Phenomenon The error message … Read more
Click on “Gua Gua Little Master” above, select “Pin/Star Official Account“ Useful Resources Delivered First Hand! Summary: I wonder how everyone prints debugging information during microcontroller development. Most likely, they use serial debugging to print. In most cases, serial port 1 is usually reserved for debugging printing during board manufacturing and coding. But what if … Read more
Resolving The Connected J-Link Is Defective Warning, Proper Operation Cannot Be Guaranteed… 1. Problem The warning ‘The connected J-Link is defective, Proper operation cannot be guaranteed…’ often pops up after repeatedly flashing the program or when the simulation frequently hangs. Insert image description here 2. Cause The issue arises because the J-Link driver for Keil … Read more

In microcontroller development, printing debug information usually relies on serial ports. However, if no serial port is reserved, the RTT (Real-Time Transfer) function of the JLINK debugger can serve as an alternative. RTT enables real-time communication between the target device and the debugging host through the JLINK debugger, supporting log output and data collection while … Read more
When we write programs, we usually use JLINK to complete the operation. It must be said that JLINK is one of the most important tools in the embedded microcontroller industry. However, we sometimes encounter situations where programming fails. Not long ago, I faced a situation where programming could not be completed. The specific situation is … Read more
