| Title: Test to verify the no multithreading use-case (ARM Only) |
| |
| Description: |
| |
| This test verifies that a Zephyr build without multithreading |
| support (CONFIG_MULTITHREADING=n) works as expected. Only for |
| ARM Cortex-M targets. In detail the test verifies that |
| - system boots to main() |
| - PSP points to the main stack |
| - PSPLIM is set to the main stack base (if applicable) |
| - FPU state is reset (if applicable) |
| - Interrupts are enabled when switching to main() |
| - Interrupts may be registerd and serviced |

| 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 |
| |

| ARM no-multithreading test |
| Available IRQ line: 25 |
| ARM no multithreading test successful |
