How to move code from flash to sram

Wayne2 — Mon, 12 Dec 2022 13:19:11 GMT

Hi NXP team

I want to move some high frequency functions from flash to the sram, in order to running in the sram which can reduce the cpu loading.

But I found it only can modify it in the settings, if I choose the "Link application to RAM", it will push all the flash code to the ram.

If I use the "Extra linker script input sections", I don't know how to specify a cpp file and then compile .o file move it to the sram.

I also found the .ld file was generated, and couldn't edit.

Could you tell me how to modify the code?

Thanks!

You can try MCUX FreeMarker, it can help you relocate part of object files to any RAM
