Hello, The JLinkGUIServer is generally responsible for hosting GUI pop-ups to interact with the J-Link, such as warnings, errors, or dialogs for inputting authentication when the target is protected. We are aware of the issue you reported and have already implemented a fix. The fix will be included in the next version, scheduled for release in the middle of next week. Best regards, Simon

Hello, Your assumption that the RTT issue is related to the size of the RTT buffer appears to be correct. I was able to reproduce the issue where J-Scope draws unexpected lines after a short period of time when the RTT buffer size is approximately 30 kB. We will investigate this further and get back to you with updates. Regarding the HSS issue, I was unable to reproduce the behavior using the HSS sample project with a sample rate greater than 100 Hz. Could you please provide the following for fu…

Hello, J-Scope is actively maintained and updated, so please feel free to request any features you find missing in J-Scope. Currently, the only solution to work with the data stream in J-Scope is to record the variables and then export the data either as a CSV file or as a RAW data stream. Other applications that support the CSV format can then be used to analyze the data. For more information on exporting sampled data, please refer to: kb.segger.com/UM08028_J-Scope#Exporting_Sampled_Data Best r…

Hello, Flash Lite only erases sectors that are included in the data file being programmed. If you have enabled config flash but it is not included in your .hex file, Flash Lite will not erase or program this flash when you press the Programming button. However, if you click "Erase Chip," the config flash will be completely erased regardless of whether it is included in your .hex file. >> would J-Flash Lite have erased this area and left it at all-1s, or would it have written all-0s? I ask When t…

Hello Francisco, Indirect programming via the QSPI controller of the STM32G474 is currently not supported. To program the Flash, you will need a custom flash loader. There are three options for developing a custom flash loader: 1. You may add a custom flash loader yourself with the SEGGER Device Support Kit (DSK). 2. You develop a custom flash loader with the help of the existing flash loaders' source code. 3. SEGGER develops the custom flash loader for you. If you are interested in any of those…
