Boot from SD Card

abady1000 — Sat, 19 Jul 2025 09:30:39 GMT

Hello,

I use NXP RT1170, my application is big, I use almost the whole OC RAM (OC1 + OC2 + ECC1 + ECC2), I sue also the other RAM Segments (DTC, ITC, SDRAM)

My application is linked to RAM, and when I upload application it uploads every segment into the correct palce it should be in.

I want now to build a bootable image form SD Card, how to do so?

My idea is to modify linker script manually and make all sections uploaded to SDRAM, then in boot CPU put every section in its correct place using Linker Load/Execute address.

Is this doable? is there other better means to achieve this?

BTW, when I use Secure Provisioning tool I get this error message after selecting my axf file:
ERROR: The selected image size 540234688 is greater than the selected boot memory size 67108864.
