## Validation Record

### Verification Environment
- **Toolchain**: Arm GNU Toolchain 15.2.Rel1
- **ROM usage**: 11716 Bytes (2.23% of 512 KB Flash)
- **RAM usage**: 7312 Bytes (7.44% of 96 KB RAM)
- **Toolchain**: Arm GNU Toolchain 15.2.Rel1 (GCC 15.2.1)
- **Static ROM usage**: 18244 Bytes (3.48% of 512 KB Flash)
- **Static RAM usage**: 5632 Bytes (5.73% of 96 KB RAM)
- **Dynamic Stack & Buffer allocation**: Stacks (8 x 1024 bytes) and Queue buffer (40 bytes) are dynamically allocated from the `TX_BYTE_POOL` (consuming 8312 bytes total, including pool headers).
- **Board Hardware**: NUCLEO-F401RE

### Hardware Verification Checklist
- [x] **Board boots successfully**: System clock configuration correctly executes and sets SysClk to 84 MHz.
- [x] **LED heartbeat operates correctly**: Onboard user LED LD2 (PA5) blinks at a steady 1 Hz interval (toggled by blink thread).
- [x] **LED heartbeat operates correctly**: Onboard user LED LD2 (PA5) blinks at a steady rate.
- [x] **UART console operates at 115200 baud**: Diagnostic outputs are cleanly transmitted over USART2 and displayed in the terminal.
- [x] **ThreadX scheduler runs correctly**: RTOS scheduler successfully handles multi-threaded execution (Blink, Worker, and Reporter threads).
- [x] **Runtime monitor output verified on hardware**: UART serial output prints thread performance stats and uptime reports every 2 seconds:
- [x] **ThreadX scheduler runs correctly**: RTOS scheduler successfully handles 8 threads with priorities ranging from 9 to 15.
- [x] **Thread Registry & Traversal**: Monitor thread queries thread names, states, run counts, and priorities dynamically using `tx_thread_info_get()`.
- [x] **Stack High-Water Mark Profiling**: Dynamic upward memory scanning verifies stack peaks (e.g., reporter thread at 42%, other tasks at 11-14%).
- [x] **RTOS Primitives Showcase**: Verified mutex lock hand-offs under contention, queue message transfers, and event flag synchronization.
- [x] **Runtime monitor output verified on hardware**: UART serial output prints thread diagnostics table and showcase counters every 2 seconds:

## Validation Record

### Verification Environment
- **Toolchain**: Arm GNU Toolchain 15.2.Rel1
- **ROM usage**: 11716 Bytes (2.23% of 512 KB Flash)
- **RAM usage**: 7312 Bytes (7.44% of 96 KB RAM)
- **Toolchain**: Arm GNU Toolchain 15.2.Rel1 (GCC 15.2.1)
- **Static ROM usage**: 18244 Bytes (3.48% of 512 KB Flash)
- **Static RAM usage**: 5632 Bytes (5.73% of 96 KB RAM)
- **Dynamic Stack & Buffer allocation**: Stacks (8 x 1024 bytes) and Queue buffer (40 bytes) are dynamically allocated from the `TX_BYTE_POOL` (consuming 8312 bytes total, including pool headers).
- **Board Hardware**: NUCLEO-F401RE

### Hardware Verification Checklist
- [x] **Board boots successfully**: System clock configuration correctly executes and sets SysClk to 84 MHz.
- [x] **LED heartbeat operates correctly**: Onboard user LED LD2 (PA5) blinks at a steady 1 Hz interval (toggled by blink thread).
- [x] **LED heartbeat operates correctly**: Onboard user LED LD2 (PA5) blinks at a steady rate.
- [x] **UART console operates at 115200 baud**: Diagnostic outputs are cleanly transmitted over USART2 and displayed in the terminal.
- [x] **ThreadX scheduler runs correctly**: RTOS scheduler successfully handles multi-threaded execution (Blink, Worker, and Reporter threads).
- [x] **Runtime monitor output verified on hardware**: UART serial output prints thread performance stats and uptime reports every 2 seconds:
- [x] **ThreadX scheduler runs correctly**: RTOS scheduler successfully handles 8 threads with priorities ranging from 9 to 15.
- [x] **Thread Registry & Traversal**: Monitor thread queries thread names, states, run counts, and priorities dynamically using `tx_thread_info_get()`.
- [x] **Stack High-Water Mark Profiling**: Dynamic upward memory scanning verifies stack peaks (e.g., reporter thread at 42%, other tasks at 11-14%).
- [x] **RTOS Primitives Showcase**: Verified mutex lock hand-offs under contention, queue message transfers, and event flag synchronization.

## Validation Record

### Verification Environment
- **Toolchain**: Arm GNU Toolchain 15.2.Rel1
- **ROM usage**: 11716 Bytes (2.23% of 512 KB Flash)
- **RAM usage**: 7312 Bytes (7.44% of 96 KB RAM)
- **Toolchain**: Arm GNU Toolchain 15.2.Rel1 (GCC 15.2.1)
- **Static ROM usage**: 18244 Bytes (3.48% of 512 KB Flash)
- **Static RAM usage**: 5632 Bytes (5.73% of 96 KB RAM)
- **Dynamic Stack & Buffer allocation**: Stacks (8 x 1024 bytes) and Queue buffer (40 bytes) are dynamically allocated from the `TX_BYTE_POOL` (consuming 8312 bytes total, including pool headers).
- **Board Hardware**: NUCLEO-F401RE

### Hardware Verification Checklist
- [x] **Board boots successfully**: System clock configuration correctly executes and sets SysClk to 84 MHz.
- [x] **LED heartbeat operates correctly**: Onboard user LED LD2 (PA5) blinks at a steady 1 Hz interval (toggled by blink thread).
- [x] **LED heartbeat operates correctly**: Onboard user LED LD2 (PA5) blinks at a steady rate.
- [x] **UART console operates at 115200 baud**: Diagnostic outputs are cleanly transmitted over USART2 and displayed in the terminal.
- [x] **ThreadX scheduler runs correctly**: RTOS scheduler successfully handles multi-threaded execution (Blink, Worker, and Reporter threads).
- [x] **Runtime monitor output verified on hardware**: UART serial output prints thread performance stats and uptime reports every 2 seconds:
- [x] **ThreadX scheduler runs correctly**: RTOS scheduler successfully handles 8 threads with priorities ranging from 9 to 15.
- [x] **Thread Registry & Traversal**: Monitor thread queries thread names, states, run counts, and priorities dynamically using `tx_thread_info_get()`.
- [x] **Stack High-Water Mark Profiling**: Dynamic upward memory scanning verifies stack peaks (e.g., reporter thread at 42%, other tasks at 11-14%).
- [x] **RTOS Primitives Showcase**: Verified mutex lock hand-offs under contention, queue message transfers, and event flag synchronization.
- [x] **Runtime monitor output verified on hardware**: UART serial output prints thread diagnostics table and showcase counters every 2 seconds:
