Undefined reference to SEGGER_SYSVIEW APIs upon integrating the patches

morpho
Been having trouble integrating systemview for tracing FreeRTOS application. I came across this thread, and even tried replacing the files with what's inside the PatchedFiles.zip folder, and I see there's an #include "SEGGER_SYSVIEW_FreeRTOS.h" inside FreeRTOSConfig.h, but upon compiling I start seeing a bunch of undefined reference errors including undefined reference to SEGGER_SYSVIEW_RecordVoid'`
Looks like traceTASK functions are invoked but it can't seem to find the reference. Anything obvious that I haven't figured out?

    Can we try this one? It may not make a difference but I just tested it again on my machine, and it works ok. At least I'm able to open the solution and build it fine.

    You could try the existing NRF's programs (ble_uart etc) but I'm mostly concerned about my own project regarding integrating SystemView. 

    Project 4.zip

    The problem was caused for me from this changes in your .emProject file

      <configuration Name="Common" gcc_cplusplus_language_standard="c++11" />
  <import file_name="../../../../../peripheral/uart/pca10056/blank/ses/uart_pca10056.emProject" />
  <import file_name="../../../../../peripheral/twi_sensor/pca10056/blank/ses/twi_sensor_pca10056.emProject" />
  <import file_name="../../../../Susheel1_ble_app_hrs_freertos/pca10056/s140/ses/ble_app_hrs_freertos_pca10056_s140.emProject" />
  <import file_name="../../../../../ble_peripheral/ble_app_uart/pca10056/s140/ses/ble_app_uart_pca10056_s140.emProject" />
  <import file_name="../../../../../peripheral/blinky_freertos/pca10056/blank/ses/blinky_FreeRTOS_pca10056.emProject" />

    I am now able to open the project but after that I have not managed to compile your cpp/hpp files with the project settings you sent. There must be some other dependency that is resolved in your system that makes SES resolve cpp linkage.

    Good to know you can at least open the project.

    Do you think it's too much an effort to investigate the main issue regarding now being able to get the program to compile after integrating the patch? I have also opened a ticket for Segger but so far no response.

    Looks like you are away now but hoping you get to see this once you're back. Appreciate your time.

    Just to reiterate, the following are among the set of errors with <#include "SEGGER_SYSVIEW_FreeRTOS.h"> included.

    FreeRTOS/app_timer_freertos.o: in function `app_timer_start':
1> /Users/Projects/BLE/nRF5_SDK_17.0.2_d674dde/components/libraries/timer/app_timer_freertos.c:194: undefined reference to `SEGGER_SYSVIEW_RecordExitISRToScheduler'

    ...

    I looked into portmacro_cmsis.h, and it doesn't seem as if it references the SEGGER_SYSVIEW_FreeRTOS.h that has a declaration of traceISR_EXIT

    #define portEND_SWITCHING_ISR( xSwitchRequired ) { if ( (xSwitchRequired) != pdFALSE ) { traceISR_EXIT_TO_SCHEDULER(); portYIELD(); } else { traceISR_EXIT(); } }
#define portYIELD_FROM_ISR( x ) portEND_SWITCHING_ISR( x )

    and I took portmacro_cmsis.h from the patch files ZIP linked in the description. Could you please confirm as to whether that's the case?

    In regards to the following errors, I'm not quite sure.




    The following preprocessor is in SEGGER_SYSVIEW_FreeRTOS.h which includes <SEGGER_SYSVIEW.h> that defines SEGGER_SYSVIEW_RecordU32x4

     #define traceQUEUE_SEND( pxQueue )   SEGGER_SYSVIEW_RecordU32x4(apiID_OFFSET + apiID_XQUEUEGENERICSEND, SEGGER_SYSVIEW_ShrinkId((U32)pxQueue), (U32)pvItemToQueue, xTicksToWait, xCopyPosition)

    Seems strange to me as to why it would not recognize.

    Would it be possible for you to check my project? I shall really be grateful!

     Thanks for waiting morpho. Yes I was away for summer holidays and due to very thin staffing here, my activities unfortunately did not get picked up by others. I appreciate your patience.

    This is clearly defined in SmartWatch\pca10056\s140\ses\SeggerFiles\SEGGER\SEGGER_SYSVIEW.c. I do not see that file included in your project. Atleast in the "Project 4.zip" attachment you did which seems the latest.
