[SOLVED] Issues switching from ST-LINK to J-LINK

Hi, Great to hear that you are up and running again. Pins 3/5 are nTRST/TDI on the JTAG interface. By default nTRST is usually pulled high. If you pull it to ground J-Link will assume that the target is held in reset and can't connect. This thread will now be considered as solved. Best regards, Nino

[SOLVED] Issues switching from ST-LINK to J-LINK

Hello, I just tried to reproduce the issue with the NUCLEO-F746ZG eval board but everything working as expected. Could you check if your custom hardware has the debug interface wired like the NUCLEO-F746ZG? Is the J-Link generally working with other target devices/eval boards? Best regards, Nino

IAR with remote J-link ARM GDB server

Hello, Thank you for your inquiry. What exactly is your setup? Is your host PC the raspberry pi? How is the J-Link connected to it. Where is IAR installed and what version are you using? What exactly are you trying to achieve with your setup? Is the STM32 the target device you are trying to program? Best regards, Nino

programming failed ATSAMD21G18 with SEGGER-EDU

Hello pak, Quoted Is it possible to restore the chip to the factory default by J-Link? We have no information about such a feature. Please contact Atmel for such information. So far we never needed to restore a chip because simply triggering the reset pin was enough. Quoted In case of ISP dose not work, I usually use "High Voltage Programmer" to restore the chip to factory default. According to the link a 12 V line is needed for this to work. J-Link can output maximum 5 V so this technique will ...

GCC sys/fcntl.h

Hello Ilkay, Thank you for your inquiry. Did you make sure you copied all your former project files to the new project? This sounds like the needed header files are either not copied over or are not included in the project. To include the folders with the header files go to: Project->Edit Options...->Code->Preprocessor->User Include Directories There enter the full absolute path to the folder with the header files or the relative path to the em.project file. If you have multiple folders then ent...

[SOLVED] Issues switching from ST-LINK to J-LINK

Hello, Have you connected the MCU supply voltage to the VTref pin (Pin 1) of the debug interface? I ask because J-Link Commander is outputting VTref = 0.000 V As our debug probes can work with ~10000 different devices a wide range different signal voltages is needed. Generally we support 1.2 V - 5 V. If you do not connect VTref J-Link does not know what voltage to supply and thus will not establish connection to protect your device from damage. How to wire the debug interface is explained here: ...

"No editors" (sub)menu ..?

Hi, Attached are two screenshots showing what I mean. So basically you can move open source files, in this case main.c and startup... .S to different window docks so you can inspect multiple files at once. When you try moving one of these open source files by drag and drop you will also see some additional window areas pop up saying "Empty Dock". These are additional places you can drop windows and sourcefiles at. Does this make more sense to you? Best regards, Nino

[SOLVED] Issues switching from ST-LINK to J-LINK

Hello, Thank you for your inquiry. Such an issue is not known to us. When setting up True Studio did you folow the following guide? https://www.segger.com/products/debug-pr…lic-truestudio/ The log suggests that the connect under reset is not working. Is the reset pin from the MCU connected to J-Link? Are you using an eval board or custom hardware? To get True Studio out of the equation could you run J-Link Commander (one of the programs in the J-Link Software and Documentation pack) and post a s...

[SOLVED] J-Link Ver6.22a not working with LPC4370 anylonger

Hi Hans, Quoted I also tested 6.22b and i still get the error. Screenshot attached. Oh bother, so it seems to be something else. The problem is that we can't reproduce the behaviour in house whatsoever so it is tough to debug this issue without a debug setup on our side. What makes me wonder is how did you give your J-Link Plus an IP address over DHCP? Did you actively change some configuration or how did that happen? If this is not your doing I suspect that the config area on the J-Link might b...

Debugging issues in secure monitor mode

Hi Isidoro, Sorry for this misunderstanding. I just read monitor mode and not *secure* monitor mode (ARM and their naming conventions ). It looks that somehow the CPSR register either can't be read or is interpreted wrongly as usually the J-Link also "does not care" on what mode the CPU is in (as long as it is a valid one). Quoted The platform ATSAMA5D2x (I'm using the SAMA5D2 Xplained Ultra Evaluation Kit) Fantastic, we have a couple of this available so we should be able to reproduce your setu...

Start application for empty SAMG55 devices in production environment

Hi, You wrote: Quoted Even a power-cycle wouldn't bring the unit up. Are you talking about the programed target device? If so then this whole issue seems to be related to the application you are trying to program into the target. When doing a power on reset the application should always start running... If it does not the programmed application is broken in some way. Try to debug the application and find out why it is not starting in the first place. If the application does not run on its own th...

Identical source files in Ozone

Hi Kevin, Thank you for providing the files. We were able to reproduce the behaviour with the provided files. To be sure where the issue is coming from we would need you to provide us your project (ideally) or at least the uVision project file to get an idea where this double information is coming from. Could you provide this? Do you build a library out of sources in your project and the library is being reused somewhere? This might be a potential sources of this double display of some functions...

[SOLVED] J-Link Ver6.22a not working with LPC4370 anylonger

Hi Hans, Ok great. This is a good indicator that it might be fixed with the latest version as well. When running your tests when it did not work, did you have multiple connections open to J-Link? For example multiple Commander instances or Commander + J-Flash etc.? Could you try out the newest version V6.22b which we released yesterday that hopefully should solve the issue? Best regards, Nino
