Relocating code from FLASH to RAM (All file)

cerma — Mon, 25 Jan 2021 14:06:47 GMT

Hi All,

I need to move the code (code/rodata) of some files from Flash to Ram. I use MCUXpresso v11.2.0, iMXRT1061. I follow MCUXpresso_IDE_User_Guide.pdf (17.15.1 Relocating code from FLASH to RAM).

Nevertheless, I still see the same values in the report (SRAM-ITC still 0B):

My changes in linkerfile:

Settings my Project:

If I only move a function (AT_QUICKACCESS_SECTION_CODE()), then everything works.

Do I have to set anything else? Where am I making mistake?

But I need to move entire files.

Thank you for answer.

Jaroslav C.

Hi Jaroslav,

please remove *(.text*) from your .text section

why/more info you can read here (MCUXpresso IDE User Guide - 17.15.1 Relocating code from FLASH to RAM):

And if you want to use MCUXpresso managed linker file...

you must add linkerscripts to your project, like in the example "evkmimxrt1060_flash_component_nor":

...changes to memory map will effects linker file only in the managed linker file mode.

Regards,
Jozef
