General • Re: How can i put a file .h in another section of memory? rp2040

That's surprising. Putting const in front of every large array was supposed to keep them in flash.

Try static const instead of just const.

Or use:

4.5.16.4.12. __in_flash
#define __in_flash(group) __attribute__((section(".flashdata." group)))
Section attribute macro for placement in flash even in a COPY_TO_RAM binary.
For example a uint32_t variable explicitly placed in flash (it will hard fault if you attempt to write it!)

Code:

uint32_t __in_flash("my_group_name") foo = 23;

The section attribute is .flashdata.<group>
Parameters
group a string suffix to use in the section name to distinguish groups that can be linker garbage-collected
independently
