Hi all,
I created a new project in S32DS with the wizard of the new application project:
Looking at initially created code, its quite different to the code of the (RTD) examples:
Application project:
Example project:
Basically it looks good, with the boot settings being there and so on. However, when integrating the RTD, issues arise.
When looking at IntCtrl_Ip.c the following is referenced:
extern uint32 __RAM_INTERRUPT_START[1U];The linker cannot find this in the "application project" as it does not exist.
In the example, this is defined within the assembler file "startup_cm7.s"
What's the reasoning behind this? Why is the startup code different between the application project and the examples? (And thus the application project being incompatible with RTD?)
Thanks
Andreas
Hi @VaneB
thanks for the reply and sorry for the delay.
My goal was to create a C++ project, but as you said, you cannot create a C++ project as it not compatible with the RTD.
Workaround: Create a standard C project with the RTD and convert it to a C++ project:
Just make sure to activate the "-nostartfiles" option in the C++ linker as have our own startup code.
Also don't forget to add your linker file to the "C++ Linker" section.

Hi VaneB,
thank you for you reply.
I am using S32DS 3.5.6 with S32K3-Real-Time-Drivers-AUTOSAR-R21-11-3.0.0-P07.
The steps are easy:
Results in:
with
__RAM_INTERRUPT_START
not being defined.
Thanks
