    Replied to the thread Difference between JLink V10 and V11 // V10 still updated?.

    Post
    You are mixing things here…. First, you asked for debug support, now, in your latest post, you are referring to production programming. These are 2 totally different things. Production programming: The easier part. You do not have to mess around with…

    Replied to the thread j-link jtag read emmc in TI am572x.

    Yes it is but you would need to create a flash loader on your own: wiki.segger.com/Open_Flashloader Sorry to say that we do not have any samples for eMMC.

    Post
    Hello, The V10 is in the maintenance period. So bugfixes will be added but no new features. Quote from Noy: “ Are there plans to support other PIC (18, dspic) beside PIC32? V10/V11 should support ICSP but why not PIC18? Would be great if i don't need…

    Hi, I see. This makes sense for sure. We will add this option. BR Alex

    Replied to the thread [SOLVED] J-Link Debug Fails.

    Post
    Hi Phil, USB: J-Link might be connected via USB but GDB and GDBServer communicate via TCP/IP with each other. Again: It is a problem in GDB. GDB is used by KDS to load the ELF file (your target application) and to interpret the debug information.…
  • OK, found it. It actually is not really a buffer overflow but glibc seems to detect it as one. Fact 1) If you remove libncurses5 from your system as part of autoremove, you make your GDB toolchain half-way unusable because arm-none-eabi-gdb depends on…
  • Hi, After executing the "purge" with "auto-remove" I can reproduce the issue. However, I can only reproduce it when starting a session from within VSCode. If I start JLinkGDBServer stand-alone but with exactly the same command line as VSCode uses, I…

    Hello, I still not understand what exactly you expect from us (SEGGER). Following your description, you are using the Kinetis Design Studio (KDS) in the following combination: KDS -> GDB <-TCP/IP-> GDBServer -> J-Link KDS: Component from NXP GDB:…

    Replied to the thread [SOLVED] Switch stack call in CCS when using Segger JLink...

    Post
    Hi, If you switch to a vanilla Eclipse or some Eclipse port that still supports the original features, you should be able to get away with the -rtos xxx option. BR Alex

    Replied to the thread [SOLVED] Switch stack call in CCS when using Segger JLink...

    Post
    TI CCS is not using JLink GDBServer but loads the J-Link lib and uses the J-Link API directly. I have no idea if CCS could still be used with GDBServer. If it can be, it is nothing that has been tested. I know that CCS is Eclipse but it is far away from…

    Replied to the thread [SOLVED] RTTViewer skips lines in logging when MCU is reset.

    Post
    Yes, this can happen when using asynchronous mechanisms. It is a bit like resetting the MCU while there is a DMA transfer in progress or before a UART was able to send out all data via Tx interrupt + buffer. Suggestion: Wait for in your software until…
  • I also checked with another VM (Ubuntu 20.04 + VMWare) I have here but starting GDBServer (same command line as you use) and waiting for the target connection etc. works fine in this VM as well. I also checked with V6.98c V7.20a BR Alex
  • Hi Godsmack et al, I just got back on this and tried the VM you provided etc. First of all: Thanks for the VM. One of the best prepared support cases ever. Download, start, description how to reproduce etc. all just perfect! Quote from Godsmack:…

    Replied to the thread CPU TAP NOT FOUND.

    Post
    Hello, Unfortunately, for RISC-V (unlike for ARM) there are no standardized JTAG IDCODEs for the JTAG TAPs that would allow identification as a RISC-V DM TAP. Just because the IRLen is 5 for RISC-V TAPs, it does not mean that any TAP with IRLen 5 is a…

    Post
    Hello, I do not think that OS aware debugging is available for TI CCS. At least not for the J-Link plugin. The CCS support was initially done by TI and we took over at some point, so I would need to look things up. In case it is possible to have some…

    Replied to the thread Maximum baud rate of J-Link VCOM.

    Post
    Hello, It depends on the actual model. On most it is done in software, on some there is a dedicated hardware UART available. Therefore, the achievable baudrates (and the max. baudrate) depends on the actual model and HW version. If you post your S/N, I…

    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…

    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?
