    Replied to the thread J-Link RTT – Real Time Transfer.

    Post
    a) Real time means that outputting a string usually does not affect the real time of your application, as it is mainly a memcpy() into a buffer, which is blazing fast. It does NOT mean that the data is immediately read out by J-Link. b) We strongly…

    Replied to the thread [SOLVED] programming VAR-SOM-MX8M-NANO with J-Link base.

    Post
    There is no(!) guarantee to get a response on the forum within 24h. If you are entitled to get support, you should contact the regular support. The i.MX8 series is currently not supported by J-Link. There is some preliminary support that has been added…

    Replied to the thread [SOLVED] nRESET as Input/Output.

    Post
    Well, it is marked as an I/O because it is an I/O. J-Link can drive it LOW and J-Link can release it and read the pin level. The pin is open drain. Input makes sense because there may be a reset button on the target HW that may be pushed asynchronously…

    Hi, Can you please let us know the model, HW revision and S/N of the unit you are seeing the problem with?

    Hi Mario, Sounds great! Can you please send the bitfile to support_jlink@segger.com ? By referencing this thread, it will end up at the correct place. BR Alex
  • Hi, We are already aware of a regression in the current V7.00 of the J-Link software, which affects exactly this device (actually it was me internally running into this). We are already working on a fix and plan to have it available by Friday.

    That’s why I asked for additional info.... I already suspected that it is the rules file but now we know it. We will fix this in one of the next versions.

    Replied to the thread [SOLVED] Need to run Flasher RX on Win10.

    Post
    By the way: The correct tool to use for Flasher RX is the "J-Flash" software. The "Flasher V2.x" software is only compatible to the legacy Flasher 5 / Flasher 5 PRO programmers which do not even support RX. J-Flash is part of the software package:

    Replied to the thread [SOLVED] J-Link VCOM max baudrate..

    Post
    There may be a misunderstanding here. You wrote: 1250000 baud => 1,250,000 baud => 1.25 MBaud The J-Link EDU V10 does not have any hardware UART on the VCOM pins, so it does things in software. This means it has a certain limit of what is doable. Max.…

    Replied to the thread [SOLVED] TMS470 on J-link with J-Flash.

    Post
    You have an TMS470R1VF67 but selected a TMS470R1B512 in the J-Link software. These two devices are not guaranteed to be compatible from the flash programming point of view. We do not give any warranty that what you are doing will work. You are on your…

    Replied to the thread segmentation fault on linux ARM.

    Post
    Hi Guillaume, Thanks for providing the log file. I do not see anything in the log file that indicates a crash / segmentation fault. The connection to the device is established, followed by a very loooong sequence…
  • Hello, So far, your chip seems to be the only one out there that does not support the traditional JTAG / SWD selection sequences. We do not have seen any other request reg. this in the last couple of years since we support SWD. There are currently no…

    Replied to the thread How to check for available licenses using command line only.

    Hi Christian, To answer your question reg. closing J-Flash with an error code if called with command line parameters, in case no license is found: We will think about that in the next team meeting which is scheduled for Tuesday. However, I cannot…

    Replied to the thread [SOLVED] Connecting to Remote J-Link via IP not resolving.

    Post
    Hi, You are confusing J-Link name with hostname here. The -ip <Name> command was never meant to resolve hostnames but was meant to resolve J-Link nick names to an actual IP. J-Links can be discovered via a special UDP broadcast packet in LAN (This is…

    Hi, We need some add. information to be able to help here. 1. What does "unsuccessful" mean? (J-Link not listed in configurator anymore once switched to CMSIS-DAP mode? Listed but re-configure throws an error? If there is an error message, can you send…

    Hi, If you can provide your S/N, we can tell you if your model supports “fixed VTref” and so can avoid having VTH connected.

    Replied to the thread J-Link RTT Viewer, save or copy log WITH colors.

    Post
    I could think about rich-text-format (rtf) output or HTML as an option for streaming to out files. This would allow colored text. For rtf of course an editor with rtf support would need to be used but there are quite some out there ;)

    Post
    Hi Jakob, There are 2 signals that sound very similar: nRST This is the reset pin of the MCU. This signal is used during programming. nTRST Test-logic-reset. Nowadays, most MCus do not even provide this signal. It is not really used during programming.…

    Hi, - Eval board or custom hardware? - Can you please get us a J-Link log file? (wiki.segger.com/Enable_J-Link_log_file) - Is the board powered externally or by the J-Trace 5V output?
