I have evaluation board without OpenSDA/JTAG interface, so I have to export the project into S32DS in order to flash and debug. I could not find the way to export .XML project file, however there is option to go to settings/Hardware Implementation/Target hardware resources/User Paths/Export generated projects/Export. When select Export, the process starts but errors out at some point with the message: The project s32k3xx_can_transmit has no generated code folder associated: s32k3xx_can_transmit_ert_rtw.
In facts the project is exported but probably incomplete since the project can be imported into s32DS but has missing header files during compile:
#include "S32K344_ADC.h" cannot be found!
In fact s32DS has an option importing the project as .elf file, but debugging is difficult in that case since it is hard to navigate variables and files in such imported project.
