I'm having an issue with data written to flex Ram.

I can partition the device(S32K144) correctly and I write some 8 bytes at the top of the flex ram (0x14000_000)

Then I COMMENT OUT the statement which writes to the flex_ram and down load the code using the PE open SDA or multilink universal on S32K DESIGN STUDIO FOR ARM. When I look at memory at location (0x14000_000), it contains all FFFFFFs which is the erased state of the flex ram when used as EEPROM, please keep in mind that the partition still preserves but the data is lost.


In the debug configuration window under debugger tab there is advanced option button that lets you preserve the partition and some memory range(I guess they are there since the PE TOOL mass erases before it downloads), for memory range I put

0x14000_000 to 0x14000_FFF which is 4k however this does not do the trick .

Any help is appreciated.
