| Title: Test to verify code execution from SRAM for XIP images (ARM Only) |
| |
| Description: |
| |
| This test verifies that we can define functions in SRAM (and |
| successfully execute them from SRAM) in ARM XIP images. It |
| also verifies that the .ramfunc section is accessible by |
| nPRIV code when building with support for user mode |
| (CONFIG_TEST_USERSPACE=y). Only for ARM Cortex-M targets. |

| Building and Running Project: |
| |
| This project outputs to the console. It can be built and executed on QEMU as |
| follows: |
| |
| ninja/make run |
| |
| --------------------------------------------------------------------------- |
| |
| Troubleshooting: |
| |
| Problems caused by out-dated project information can be addressed by |
| issuing one of the following commands then rebuilding the project: |
| |
| ninja/make clean # discard results of previous builds |
| # but keep existing configuration info |
| or |
| ninja/make pristine # discard results of previous builds |
| # and restore pre-defined configuration info |
| |
