Hi Kalidass, 

which example do you mean? I'm not able locate " FTFE->FSTAT = FTFE_FSTAT_CCIF_MASK; " row in any of S32DS examples. Can you share the project?

Hi Jiri,

You can find this instruction in the project shared by Lukas Zadrapa in this thread :

PROGRAMMING THE S32K FLASH

Hi, 

I tried the example with S32DS v1.3 and S32DS v2.0 - and it is normally working. I can see modified Flash memory. 

I'm using Windows 7 and S32K144 EVB-Q100 with Open SDA debugger. So -I'm not able reproduce the issue.

Hi,

Indeed, the example code works but when i try to execute this code in my project in run mode, the code crash. But if i execute flash instruction one by one with breakpoints between each instruction, it works fine.
I place the code in .code_ram section ( Section define by default in a 32DS ).
I try to create a new section with memcpy of section, and i have the same result.

I don't know what i miss.

The startup code can be accused ?

Hi, 

I'm not able reproduce the issue - can you please share  your project? I can attach to running machine and the Flash memory is successfully modified and there is no exception or other error.

Hi,
I found my problem, I have interruptions during the flash commands.
So i need to disable all interrupts during flash commands.

Thanks for your help Jiri.

    thanks!

Hello, 

you can use SDK functions INT_SYS_DisableIRQGlobal(); and INT_SYS_EnableIRQGlobal();
