Intel ADSP CAVS Code relocation
Overview
A simple sample that shows code relocation working for Intel ADSP CAVS boards (v18 and v25). The interesting bit is the custom linker file. As rimage (the tool used to sign the image) mandates that elf files sections TEXT, DATA and BSS be contiguous, some work is done in the linker script to ensure that.
Building and Running
This application can be built and executed as follows:
west build -b intel_adsp/cavs25 samples/hello_world
