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…

Hi everyone, question for J-Link BASE Classic in combination with J-Link Software and Documentation pack versions (currently the latest version is V8.34). Is a J-Link Software and Documentation pack version somehow connected with the end of support…

I'm working on a project that uses a Nordic nRF chip and the Zephyr RTOS. I've started using SystemView to try and debug an issue that I believe is related to thread management. I set everything up correctly and I'm able to use SystemView, but after a…

Hey folks! Apologies if this has been answered before and my forum search skill are lacking. I'm trying to confirm my understanding of the behavior of "-speed auto" parameter of "JLinkGDBServerCL". Is it basically equal to "best possible speed given the…
