Relocate library functions to ITCM

nickwallis — Mon, 14 Mar 2022 14:17:04 GMT

Hi,

I would like to relocate string handling library functions (e.g. strcat()) so that they are run from ITCM.

How should I do that please? I think these come from libc, my project is using Newlib.

thanks!

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) How should I do that please? I think these come from libc, my project is using Newlib.
-- It's able to make it via modifying the linker file, so I'd like to suggest you refer to the user guide of the IDE you used.
Have a great day,
TIC
