Hi,
I have 2 elfs that I try and flash and than debug on S32.
The flashing seems to work, and and debug even goes from startup to main.
BUT ...
When I look at the section to which I refer it seems messed up, and does not match either elf:
pegdbserver console:

and from reading the flash while in debug:
Hello,
are these two elf files created by S32DS or by different IDE?
If you have multicore project created by S32DS, you can simply use LaunchGroup option to load and debug.
If you want to load and debug elf files which does not come from S32DS, please see article below and use point 3. Instead of single core project, create multicore project and use it's debug configuration (LaunchGroup configuration).
HOWTO: download separate elf/srec file to microcontroller using S32 Design Studio
I suppose these two elf files are files for different cores and I suppose you have correctly created linker files.
Also this is not elf file, but Srecord file. elf file is binary file which cannot be correctly interpreted by text editor.
elf1:
S319011CF0000000000201002FB00000000001002E16006600004C
S315011CF01401002FB80000000001002DB0006600009D
In case my advice does not help you, could you please write me back more details about microcontroller, files you try to load and eventually post here the whole project or at least the files you try to load into the microcontroller.
Regards,
Martin
