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

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
