Memory Configuration and Linker Script

KAVIN_M — Tue, 11 Feb 2025 04:23:18 GMT

I'm working on the iMXRT1176 using MCUXpresso IDE, need to add 2 new parts with existing Board Flash.
For example, Memory A (0x30000000), Board Flash (0x30040000), Memory C (0x30080000) it is done within the MCU settings (properties).

Question:
Now My code's text section needs to map to Board Flash. How to do it?

Hi @Gavin_Jia
Thanks for your response

I read it and shifted my section from Flash 1 to Flash 2 (refer the img).
But in debug.ld still the content in the Flash 1 remains the same. Then the %age used in clear
Is it ok to accept this as correct change ?
