    Replied to the thread J-Link Flash Loader: erase and program maximum times in FlashDevice.

    Post
    EraseSector() must only return when the erase of the sector is complete. The timeout is a value that must not exceeded by an EraseSector() call.

    How much current does your board draw? Did you make sure that it is within the specs of J-Link? Did you make sure that you have connected J-Link to a USB hub that has its own power supply? If not: Did you make sure that J-Link is the only device…

    Post
    Hi, Can you please provide the full Python code, command files etc. you are using to get RTT data from JLink.exe? If this is an issue on our side, we need some more information about the exact setup and what exactly should happen, according to the code.

    Can you please describe what exactly you are doing? - Starting nrfjprog.exe to program the device - Exit nrfjprog.exe - Starting jlink.exe to do what? How do you get the RTT data? Do you connect directly via TCP/IP to a specific port? Do you instruct…

    Hello, We are currently investigating an issue with TMS570LS devices and the latest CCS plugin. It is not related to the "The selected device xxx is unknown to this version of the J-Link software" dialog you are getting but may cause debugging to not…

    Only one process can listen on a port. If you start nrfjprog.exe first, it gets the 19020 port, so it will be the default instance RTT Logger connects to. You either need to add a delay between exiting nrfjprog.exe and starting JLink.exe (otherwise you…

    Thanks for confirming that it was an issue in your setup. Pulling the plug in the middle of the work is like getting your hands of the steering wheel of your cars when driving on a crowded highway and a high speed. There is a pretty high chance that you…

    Hello, I understood it that way but thanks for summarizing to avoid misunderstandings. This does not change the fact that pic1 shows "V6.44b" in the message box title and not "V6.88". Do you agree? So the fact that the message box shows a version !=…

    Replied to the thread [DUPLICATE] JLink EDU Mini + SAMD21G18 compatibility issues.

    Post
    While we cannot comment on the compatibility to the board, the MCU should not be an issue. As you stated in the other thread, you can connect to the MCU via J-Link Commander (JLinkExe), it is proven that the EDU Mini is fine. If VsCode does not work,…

    Currently, only [mA] is available and there are currently no plans to support anything else than probably [uA]. Accumulated power consumption: Currently not, but we will put it onto the agenda for the next meeting

    Replied to the thread Reading out Unique Identifier of MCU using JTAG.

    Post
    Actually, I do not see why there is any RAMCode needed at all. It should be a few memory writes followed by a read, to get the UID. We can offer to write such a script as a service if you would like.

    Something reg. your statements cannot be correct. As can be clearly seen in the screenshots, the message box from CCS shown J-Link V6.44b and not V6.88 like the Commander etc. Without having checked the release notes I would say that the TMS570LS20216…

    Replied to the thread Flashed command for STM32G0.

    Of course it will not work if you select „Cortex-M0“.... This is why we offer different device selections because every device has a different flash algorithm. Cortex-M0 does not tell J-Link ANYTHING about how flash programming for a particular…

    Replied to the thread MKRWAN Bootloader - mkrwan appears unresponsive.

    Post
    Actually, it more sounds like you either had a bad/incomplete bin file or flashed it to the wrong address, so J-Link is probably the wrong thing to blame here. J-Flash Lite uses EXACTLY the same flash programming logic as JLink.exe does.

    The out of sync message is related to USB. The USB protocol is out of sync. Meaning, the PC may have sent a half command to J-Link, so it is still waiting for the rest of the command etc. Or the PC did not get the whole answer to a command out of the…

    Hi, At least on the photo, you have NOT connected the battery to pin 1. Pin 1 is indicated by the BLUE wire on the cable. Maybe that‘s also the problem on your custom board wiring: Wrong direction of the debug connector... BR Alex

    Can you please post the log output you get? It obviously must be different from the first log you provided in the beginning of the thread.
