Hello, Thank you for your inquiry. Please understand that we do not provide support for such old Embedded Studio versions as they are out of maintenance and thus support. Is the issue reproducible with the latest Embedded Studio version V7.12 as well? If yes could you provide an example project for reproduction with reproduction steps? Best regards, Nino

Hello, Thank you for your inquiry. No there is no way around the MAC address if you plan on using the free Nordic license. But you can of course generate as many licenses as you want. If you have a build system that e.g. does not have a fixed MAC address we recommend to purchase a so called "Automated Environment License". segger.com/purchase/licensing/license-cul/ For a quote feel free to contact our sales: segger.com/purchase/request-quote/ Best regards, Nino

Hello, Thank you for your inquiry. Could you try using the latest SystemView sources and SystemView version? You seem to have a version mismatch there. Additionally here is a Wiki article describing how SystemView should be used on FreeRTOS: wiki.segger.com/FreeRTOS_with_SystemView For more details about troubleshooting see the SystemView reference manual. Best regards, Nino

Hello Matthias, is this matter resolved? Because in your other thread you wrote that you were able to instrument your application as documented. Best regards, Nino

Hello Matthias, Thank you for your inquiry. Generally when using SystemView J-Link will not reset the device on record start. Only if necessary. There are sometimes chips or even architectures that do not support attach mode so this might be one of them. How did you determine that the device is reset? What kind of reset is issued? Reset Pin toggle or Software Reset? Are you using FINE or JTAG as debug interface? Could you provide a J-Link log of the SystemView session? wiki.segger.com/Enable_J-L…

Hello, Thank you for your inquiry. In release build configs usually code optimization is enabled for the compiler. Depending on how and where your ITM prinf calls are written and how aggressive the compiler optimizes it is possible that it will simply throw the printf calls out. Try experimenting with the different optimization levels. There are also "tricks" in C which can be applied so the compiler won't throw certain code away. For that there are multiple different guides in the internet. Bes…

Hello Pawel, Thank you for your inquiry. The described behaviour is not reproducible for us. If I have a COM port device connected to my host PC, one I click OK I get the selection dialogue to pick which COM Port I want. This works for both 3.42 and 3.20 for me. Could you check in your device manager if your UART/COM Port device shows up correctly? If yes, could you provide a screenshot of the entry? Best regards, Nino

Hello, Thank you for your inquiry. This thread will be closed now as you opened a support inquiry via our support channel in parallel and the inquiry was handled there. For future inquiries we recommend to use only one contact channel to avoid duplicate information. Best regards, Nino

Hello, Thank you for your inquiry. Are your recorder settings betwen your PC and the one of your coworker also the same? You can check them under Target->Recorder Configuration->J-Link If they are the same, what are the settings. Could you provide a screenshot? Best regards, Nino

Hi Max, If I understand you correctly you are looking to track your heap usage. Correct? In that case the general approach to overwrite the heap_lock and _unlock functions is wrong. That functions are only meant to assure interrupt or mutex locking as explained in the Wiki article. They are not meant to be misused for other purposes like memory management. Instead our recommendation if you plan to track your heap usage to simply write your own external routines either by calling them periodicall…

Hello Clemens, The issue has been fixed in Embedded Studio V7.10. Best regards, Nino

Hello, Thank you for your inquiry. Every Embedded Studio version works standalone. The difference with the latest version is simply that we are now building the architecture specific standard libraries on demand. Thus the installer and initial installation size of Embedded Studio is reduced drastically. So yes, you can install and uninstall every Embedded Studio version that you have without impacting one another as they are all independent installs. I hope that clarifies it. Best regards, Nino

Hello, Thank you for your inquiry. Quote from Aniket Shet: “I wanted to build my entire project but by using emBuild. Which has lot of source files and included header files. In above example it shows only how to build one main file. I want to know how to go about doing this. ” We recommend to do it with the project file for exactly this reason. Otherwise you have to generate the whole command line on your own. Instead we recommend to setup your build environment in the GUI version in Embedded S…

Hello Pawel, Thank you for your inquiry. Could you elaborate what exactly would you want to see with the variables? Generally it is possible to add variables to the data graph in Ozone and track variables via the timeline together with the trace data in the same window. See Ozone manual for more information. Best regards, Nino

Hello, Thank you for your inquiry. Such an issue is not known to us. What target device are you running on? Could you provide an example project for reproduction that could run on an eval board? What is the S/N of your J-Trace Pro? Best regards, Nino

Hi Phillip, You can also share the patches here of course. Best regards, Nino

Hello Phillip, Thank you for your inquiry. Sounds reasonable to me. Could you provide the patch files via our support channel as explained in my signature so we can take a look? Best regards, Nino

Hello Phillip, Thank you for sharing. On first glance this looks good. We will run some tests on it and if everything passes it will most likely be added to the official release. Best regards, Nino
