    Not sure what you mean with “There must be a simpler way”. What do you have in mind? Can you describe the “simpler” setup you have in mind? As RTT goes through the debug interface, you need an active debug session that does all the RTT handling…

    Hi, Does the latest version still show these effects? V7.90 is from August 2023 (while we are currently in Feb 2024) and there have been several updates since then. segger.com/downloads/jlink/ BR Alex

    Even more unfortunate that you did not mention the exact device in use in the first place and that you were missing support, but instead let us guess and invest time into an answer that you already knew / probably expected... However, I invested some…

    As the bottleneck is mainly the debug interface, USB3 probably gives a bit of better performance over USB2 in this discipline but if it is significant or even crucial, is something only you know. I do not have any USB2 vs. USB3 RTT comparisons at…

    Hi, Well, you need to pass the correct name to J-Link… Not all devices share the same algorithm and flash size, so J-Link needs to know which device it is talking to, in order to have the correct algorithm selected. List of valid device names for…

    The statement you quoted refers to the tome needed on the MCU side to get that line into the RTT buffer. This is “the important time” because it is basically the time that your application is blocked from doing its normal work. When the buffer is…

    As the SDK is not free of charge / open, I recommend to use the official support channel for it. (See signature below my post) Otherwise, your posts may get hidden / deleted. BR Alex

    OK, so this is unrelated to the Linux issue we fixed with V7.94e. We will check if we can reproduce things.

    RTT has no guaranteed timing. J-Link polls the RTT control block on the target for new data, as fast as possible and whenever there is data, it is read. The point is to get data out of the target as fast as possible, so buffers on the target can be kept…
  • Hi, There is no probing / trying (and has never been) for the correct pin config for exactly the reason you mentioned. J-Link detects the connected flash by reading its ID via the RDID command but there is always a fixed pinout used. Can you please…

    Do you mean V7.94d or really V7.49d? If it is V7.94d: Do you also see the issue with V7.94e? There was a hotfix for Linux in that version but in case it fixes a problem on your machine as well, we will have a look again what happened for macOS because…

    Hi, There was a V7.94e with a hotfix for Linux. Pretty sure that you ran into that issue. segger.com/downloads/jlink/#J-…twareAndDocumentationPack BR Alex

    Replied to the thread [SOLVED] Issues with GDB debugging.

    Post
    Hi, A J-Link script file is the wrong approach here. GDB Server has zero knowledge about the ELF file. All the debug information parsing (function/variable names, stack frames, ...) is done by GDB which has access to the ELF file. GDB only provides the…

    As far as I understand, it should be possible. Make sure this is part of your FPGA config: github.com/SpinalHDL/VexRiscv#debugplugin and afterwards, the core should be available via JTAG. By using J-Link Commander, following this sequence:

    Hi, No logic inside the J-Link software interprets rhe RTT data. It is just forwarded from one side to the other (host -> target or the other way around). All the interpretation of the data itself is up to the host and target application. We will check…
