Hello,
I want to write data directly to the P-Flash on the S32K116 without applying any partitioning. In the first image I shared, you can see that the data is written successfully.
Then I try to erase the data I wrote. However, when I do that, it erases 0x50 bytes. You can observe this in the second image. I also shared the contents of the wrapper function used for memory erase in the third image.
Additionally, when I stop debugging and start again, the values I wrote to Flash appear to be already erased.
Could you please help me understand what's happening?
Thank you in advance.

Hi @Senlent ,
I have two questions:
I'm asking to confirm — does a flash mass erase happen every time I enter debug mode?
I don’t want to debug, I only want to flash the code as shown in the screenshot below (RT1176, MCUXpresso). Is there a feature like this? I couldn’t find it anywhere.
Thanks for your helping.
Hi@mehmetkaradag
1.I'm asking to confirm — does a flash mass erase happen every time I enter debug mode?
Yes, but you can set preservation for some memory.

S32 DS Platfrom have no such feature available, but S32 DS For Arm does.
Hi again @Senlent,
Thank you for all your help first.
I have one last question for you:
When I modified the linker file of the user application, I noticed that the changes are not reflected in the map file. The linker file was originally shared across all SDKs, but I separated it and made it independent — meaning it now points to the one I specified. I’ve attached a screenshot below. However, since the changes are not reflected in the map file, I’m unable to start the user application from the memory region I want.
Could you please help me with this?
Thank you!
