Hello,

Thank you for your inquiry.
Such an issue is not known to us.
The file was tested for Cortex-M4 and gcc so it should work. Are you sure that your build options are set up correctly for Cortex-M4?

Alternatively what you could try is set preprocessor define RTT_USE_ASM = 0 in your project. Then only the C source will be considered and the assembler file ignored.

Best regards,
Nino

Hello,
I have the same issue, when I use "as" command, I managed to compile this file using gcc and g++ commands. What is the proper way of compiling this file? Do you have or can create reference project for ATSAMV71-XULT board? I use ATSAMV71 on my custom board, but reference files with a tutorial would help a lot.

Hello,

Not sure what your issue is. It is a simple gcc/clang compatible assembly file. If you have your general toolchain setup correctly all you have to do is add the file to your project and build it.
If this does not simply work your general setup is most likely not correct.

For reference in our embOS release page you can find startup project for multiple boards. embOS is our RTOS which is also instrumented by SystemView via RTT. So everything is setup already and can be compiled and debugged with our IDE Embedded Studio. For evaluation both embOS and ES can be used for free.

embOS downloadlink:
segger.com/downloads/embos/emb…texM_EmbeddedStudio_Trial
ES downloadlink:
segger.com/downloads/embedded-studio/#ESforARM


You can find an example project for the SAMV71Q21_SAMV71_XPlainedUltra board and SAMD21E18_SAMD21_XPlainedPro under the following path in the embOS zip:

.\Start\BoardSupport\Microchip


Simply build the projects with ES and load them into the corresponding eval boards. Then you should be able to debug the application and record with SystemView.

As you can see from the project setup the RTT files are simply in the SEGGER folder and build just fine.


Best regards,

Nino
