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?

The person best fitted to answer this is out of office at the moment. But I found some other links that may be helpful:

Are they still out of office? I have already looked at these links and tried out to no avail

Sorry, did not try your project as I got used to SES for debugging.

I mean for my project, you have to open the project file inside "ses" as well. Can you please check? thought that was the point of initially asking me for the project link

Also I just tried your project and I see the same issue as what I encountered before: "Could not find RTT Control Block. Timeout: 20000 ms"

Are there any settings that I am supposed to be configuring? I just click on the "Start Recording" option after starting the program

I am really sorry, Not sure what happened but the main.c file did not include the change i did.

Basically you need to call "    SEGGER_SYSVIEW_Conf();" in the main.c very early. This will initialize the RTT control block properly in a way that systemview can search for it. Can you please check if it works for you with that addition of line in your main.c and also you need to have .SEGGER_SYSVIEW_Config_FreeRTOS.c file in your project which I see missing.

Reattaching my changes,

It is working for  me here. with my project

I can't compile your project as I have some issue with multi C++ compilers mixed up in my settings. I will have to solve that issue another time
