CycloneDDS on S32G3 NXP platform

[rizahmad]

Hello,

I am interested in building an application for Cortex-m7 core of S32G3 NXP platform. Has anyone tried building cyclonedds for an embedded target and was successful? I have FreeRTOS along with lwIP setup for Cortex-m7 core. And was able to cross-compile CycloneDDS using GCC 10.2 arm32 compiler from NXP. There was a linking issue with __aeabi_read_tp symbol missing, which I added to the CycloneDDS source code and rebuilt. But still there are places where the code will access a bad memory location and crash.

So I want to ask, if someone has actually run it on an embedded target (FreeRTOS on Cortex-m/r and with lwIP)?

Best regards,
Rizwan.

PS: I am trying to run the helloworld_subscriber on NXP S32 G3 Cortex-m7

Update: Successfully brought up CycloneDDS on NXP S32G3 🎉

The current stack is:

CycloneDDS
--------------
lwIP
--------------
FreeRTOS
--------------
RTD 4.0.2 HF03

NXP S32G3

Basic communication is now working end-to-end, between an ubuntu laptop and the NXP board. I’ll follow up soon with a detailed, step-by-step guide covering configuration, integration details, and lessons learned.
