FLEXRAM Usage As SRAM

kesanli_cinci — Fri, 08 Mar 2024 10:19:53 GMT

Hello,

I want to use FlexRam as SRAM in s32k116 microcontroller. In default, FlexRam is configured as RAM. How should I add FlexRam section to linker file?

I want to reduce SRAM usage which is 15kb in S32K116. That's why, I plan to use FlexRam as SRAM to add additional 2kb memory. I can not concatenate SRAM and FlexRam directly, because its start address is 0x1400 0000. I think that I probably need to define FlexRam in linker file and then I can store some data in FlexRam after defining it linker file.

In order to store data in FlexRam, should I use "__attribute__" ?
