HSE DATA FLASH Usage

[S3RD4R]

Hi all,

In the Crypto_SymmetricPrimitives example's linker file, it says "Last 128 KB of DATA_FLASH reserved by HSE Firmware (not supported in this linker file)".

My MCU is s32k344 and it has a data flash of 128KB. If this is true, when HSE is enabled in any application, i can not use data flash? I was hopng to store some of my parameters in data flash and i am also using HSE.

I am confused about this. Any help will be appreciated.

Thank you,

Hello,

In reference manual in the application boot chapter you will see which memories are available for application:

In case HSE is enabled it will take a small portion of Data flash and for application will be still available 88KB.

Best regards,

Peter
