| 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 on QEMU as follows: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: intel_adsp_cavs25 |
| :goals: build |
| :compact: |
