Hello, I just installed and tried the latest JLink on a MacBook. I get the same result as on Linux: tmohr ~ $ /Applications/SEGGER/JLink_V644h/JLinkExe ; exit; SEGGER J-Link Commander V6.44h (Compiled May 3 2019 17:40:43) DLL version V6.44h, compiled May 3 2019 17:40:32 Connecting to J-Link via USB...FAILED: Cannot connect to J-Link via USB. J-Link> I also tried connecting to the LRWAN1 with an older version of Ozone on a Windows 10 PC but don't have a screenshot or log. Also there, the board is…

Hello Nino, I use openSUSE Leap 42.3. I debugged several STM32F407 Discovery on the same PC and OpenSuse installation. I can try another PC, but that may take some time. It will be a Windows 10 Laptop. Best regards Torsten

Hello Nino, Thanks for your help. Correct, the board should be supported. Please see the screenshot attached. It seems to fail on a very low level. It is the same result for both boards I have (STM32L072CZ). The standard program that is on the STM32L072CZ is still running as expected. The green LED in the STLINK part is blinking with approx. 5-10 Hz. I updated at least three STM32F407 Discovery the same way and they all work as expected. I have a normal standard J-Link, maybe I can use that one …

Hello, I have a Board B-L072Z-LRWAN1 with an STM32L072CZ. I use Ozone V2.62 / 2019-04-09. I reflashed the ST-Link on the board, but only get: Debug.SetConnectMode (CM_DOWNLOAD_RESET); Debug.Start(); Connection failed Is there any way to track the problems down any further? Does anybody use the LRWAN1 with Ozone successfully? EDIT: When I write that I reflashed the ST-Link, then this means I used the Segger tool to flash the alternative firmware that enables the use with Ozone. It seems the board…

Hello, in the J-Link manual there is a target connector layout described as 9-Pin. Also, an adapter is mentioned there (chapter 16.3). Where can I get that adapter for J-Link to the 9-Pin target? I did not see it in the online shop. What other debug connectors for an ARM Cortex-M are there and would make sense to use? I'd like to use a reasonably small standard connector. Thanks for any hints Torsten

Hello, Will J-Link and the tools like Ozone support 64 Bit controllers / cores like Cortex A53 / A57? Best regards Torsten

Hello, to display the registers ofnperipherals I use the memory view, which is not very readable. Are there plans to add a description file that describes how the memory maps to readable peripheral registers (like PER files in Lauterbach)? Or am I missing something and this already exists somehow? Best regards, Torsten.

Quote from markus_rudolf: “Maybe think about converting the onboard ST-Link to an "official" JLINK segger.com/jlink-st-link.html and save the hazzle with the external one.” Thanks for this hint, I bought another STm32F4 Discovery board and tried the description on the page above. All works fine, much less wiring now. Best regards Torsten

That is not 100% correct. Sorry if i was imprecise. Yes, reloading means saving a project, quitting and loading the project on the next start. Let me describe my steps: 1. set up a project, do some settings, debug (this gives ozone_normal.png) 2. then save the project as jlink.jdebug. 3. quit Ozone 4. restart Ozone 5. load jlink.jdebug (this gives ozone_reload.png) => the sources are not displayed. So I think something is either not saved or not updated after loading a *.jdebug project. Best reg…

Hello, first let me say that I'm quite glad with Ozone, to have a working debugger on Linux. When working with it on an existing project I get the screenshot as attached during debugging (ozone_normal.png). When I reload the project and flash it into the target then I would expect to also see the same sources displayed, but the code is not displayed at all (ozone_reload.png). I would expect to see the sources displayed even directly after loading the project. But after flashing the code into the…

Hello, I refer to AN00021 on how to connect J-Link to an STM32F4 Discovery. It did not work for me and according to this description the solder bridges SB11 and SB12 also need to be removed: st.com/content/ccc/resource/te…lations/en.DM00039084.pdf I thought you may want to add this in there. Only after this change I could connect to my STM32F407. Maybe I missed this point somewhere? Best regards Torsten

Thanks for your hint, now the power is on. I have read the manuals before thoroughly but missed that point. Thanks, Torsten

Hello, I use Ozone (x64) on Linux, version is 2.20g, compiled on 2016-10-05. As target Device i chose STM32F407IE, target interface SWD, speed 1 MHz. When I press "Finish" in this dialog then I see in the console window: p, li { white-space: pre-wrap; } J-Link software found at: Project.SetDevice ("STM32F407IE"); Project.SetHostIF ("USB", ""); Project.SetTargetIF ("SWD"); Project.SetTIFSpeed ("1 MHz"); Project.AddSvdFile ("Cortex-M4.svd"); Project.AddSvdFile ("Cortex-M4.svd"): invalid filename I…

Hello, I'm unsure, I already sent one J-Link back as the 5V Supply seems dead, it does not supply 5V. I try to power an STM32F4 Discovery with it and double-double-checked the wiring already. I expected that there would be 5V available when I plug in the J-Link (measured between pin 4 and pin 19). I don't think the wiring is incorrect as when I externally power the Discovery board I can read a valid VTref on pin 1: SEGGER J-Link Commander V6.10c (Compiled Sep 28 2016 18:30:32) DLL version V6.10c…

Hello Johannes, Thanks for your help. I'll attach the output of the Help report to this Message. My System is basically OpenSuse 42.1 with some media extensions from Pacman: tmohr@schleim:/tmp> cat /etc/os-release NAME="openSUSE Leap" VERSION="42.1" VERSION_ID="42.1" PRETTY_NAME="openSUSE Leap 42.1 (x86_64)" ID=opensuse ANSI_COLOR="0;32" CPE_NAME="cpe:/o:opensuse:opensuse:42.1" BUG_REPORT_URL="https://bugs.opensuse.org" HOME_URL="https://opensuse.org/" ID_LIKE="suse" I guess you may be intereste…

Hello, I just downloaded and installed SES 3.10d for Linux: Release 3.10d Build 2016092700.29750 Linux x64 When I open it, it loads a default project and displays the source as in the attached screenshot. This seems like a bug to me. Is there any setting where I can influence how the code is displayed? Is the behavior known and already fixed somewhere? Can I report this somewhere? I only use the EDU version. But I guess the guys at Segger are interested in this. Thanks for any hints, Torsten
