    Hi,

    i've initially implemented the SystemView 2.32a tool into a DS-5 project.
    I'm running FreeRTOS 8.2.3 on a LPC4350 M4 microcontroller while debugging with GDB Server 4.98a and J-Link Ultra+.

    I'm using the default settings for SystemView and no FreeRTOS patch.
    Only calling SEGGER_SYSVIEW_Conf(); in main() and the #include "SEGGER_SYSVIEW_FreeRTOS.h" statement at the end of FreeRTOSConfig.h.

    On starting the SystemView recorder with Target Device LPC4350_M4, JTAG interface and manually RTT Control Block Address it will fail at least 8 out of 10 times with the error: "Failed to start recording. RTT Control Block not found."

    Can anyone make suggestions whats going wrong there?

    Thanks and best regards
  • Hi Johannes,

    thank you for the quick reply.

    Updating to the newest J-Link Software isn't possible for me because of the problem mentioned here.
    Maybe you can also give an suggestion how to get the newest version running.

    As a first step - using SystemView without GDB Server is working for me. After stopping GDB Server the start of SystemView works fine.

    Thank you!
    Best regards
