Hi, I am trying to modify the simulation to use "Custom bitmap mode" to add my device background to the simulation following this section: Simulation I am able to add my custom bitmap (Device.bmp and Device1.bmp) to add my device bitmap and a bitmap…

Hi, it seems that version V8.36 has the fix for this thread: Release notes for the J-Link Software and Documentation Package Release notes for V8.36, ubder Device Provisioner: "When given only a script file name DevPro would no longer automatically…

How can I start RTT server from JLink.exe, - since I'm connected via working interface - and application is already running with "go". But I don't see the system tray icon and status page won't load localhost:19080/rtt.htm I'm trying to do a…

Hello, We are currently working on toggling a GPIO pin on the STM32MP257F-DK board using the Cortex-M33 core, with Segger Embedded Studio (SES) version 8.22a. We are able to toggle the GPIO as expected. However, we are encountering an issue when…

Hello, I'd like to use newer JLink software (I'm currently on version 7.92c) for the JLink programmer device to program external memory connected to IMXRT1176 microcontroller. I already have a working solution for an older version that I currently use,…

Hi, question for a possible workaround (also for other future users) ... Would it help if we just make a clean installation? In my case, I've always performed the "Upgrade existing installation" and have "C:\Program Files\SEGGER\JLink" path in Windows…

SystemView's manual page 68 currently states: Quote from SEGGER SystemView User Guide: “4.5.1.4 SEGGER_SYSVIEW_LOCK() Function macro to recursively lock SystemView transfers from being interrupted. I.e. disable interrupts. SEGGER_SYSVIEW_LOCK() must…

Hi, I have created a screen with multiple wheels for user input into a text box. These are the types of wheel I have created: 1. Text wheel 2. Action wheel I realized that WHEEL apis commonly available for text wheels are not easily accessible for…

Hi Florian, Thank you for the response! Quote from SEGGER - Florian: “dynamically switch out the content list ” I am not sure how to do this dynamically. It would be great if you could give an example. Here in the API: int WHEEL_AddBitmaps …

Simon hi, yes, it seems that full path approach has a working results ... results attached (V8.24 and V8.34). Used full path command: DevPro.exe -operation ReadOptionBytes -if SWD -speed 4000 -SetConfigVal "OptionName=FLASH_OPTR" -ScriptFile "C:\Program…

TACTICAL COMMENT I second that question. I was also wondering how the speed is being set underneath.

Hi Simon, Can JLinkSWOViewerCLExe and JLink Commander sessions coexist at the same time? best regards Max

Hello, The SWO Viewer should be a suitable tool for this use case. It is included as part of the J-Link Software & Documentation Pack. For instructions on how to attach it to your target, please refer to: kb.segger.com/J-Link_SWO_Viewer#-swoattach Best…

Hello, Please note that the support period is not tied to the J-Link Software and Documentation Pack itself. Once your support period ends, you simply no longer have entitlement to direct technical support. Regarding your issue: Could you try…

Problem solved: The STM32WB55 requires writing double word (64-bit) to flash.

Same setup and conditions: Example for V8.24 ... working condition (Capture_V8_24.PNG). Example for V8.34 ... not working condition (Capture_V8_34.PNG). In addition, for SEGGER staff, release notes for V8.34 are still missing: Release notes for the…

Is it possible to flash the option bytes on an STM32WB55VC chip using Segger products (preferably J-Link or J-Trace). From the target menu (J-Flash) I do not see the (allow opt. bytes) for this chip. When I write to the option bytes registers directly…

Just upgraded from 3.38 to 3.38g I have an "intentional" divide by zero error to test HardFault handling .. when the exception fires, the Cortex-M UsageFault Exception window shows but the Exception Registers section is empty. This is using a SAME7021B…

I’m working in a production setup (not a development/debug session), where each board must be prepared before its main flash image is programmed. Our process is (simulated with EVK): 1. Connect to the MIMXRT1021-EVK via a Segger J-Link (SWD + SWO). 2. …

Hello, I have a custom flash loader that works with JLink and is able to do a basic operations like write, read, erase and L1 verification (L2 is not implemented for now). I'm using python pylink library to handle the JLink device and automate these…
