About S32K144 EEPROM re-downloading program, data not stored

[Lw2]

The function I want to achieve.
Store the data in eeprom and not lose the data when re-downloading the program using PE.

I have made the following attempts.

1.I referenced this example Example: S32K144 EEEPROM usage - NXP Community

，But it didn't work.Here is my configuration:

Then I changed the Preserve this range from 14000000 To 14000fff to 10000000 To 1000ffff. But it didn't work either

2.   When I replaced the PE downloader with J-LINK, the data inside the EEPROM is not erased after J-LINK downloads the program. So I think if my PE downloader is not configured properly, but I didn't find the problem. If anyone knows, please let me know.

Thank you very much!

Hi,

I did quick test on my S32K144EVB using inbuilt OpenSDA interface from Pemicro and the same configuration is working on my side, the EEE data are not erased. I will test it with Multilink FX tomorrow to see if it makes a difference but I don't think so. I will let you know.

Regards,

Lukas

First of all, thank you very much for your reply.
I am using IDE S32DS version 3.4, maybe I didn't configure it properly during installation, but I did try many times and it didn't work, every time after re-downloading the program, the data written before was not there.

Well, I tested it with Multilink FX now and it also works as expected. I used S32DS 3.4 too for my test. I can't see a configuration which could make a difference.

I seem to have found the problem because I checked the Emergency Kinetis Device Recovery by Full Chip Erase, as shown below.

Thank you very much for your reply
