# BCM5719 Firmware Reimplementation
## Introduction
This library contains a clean-room reimplementation of the BCM5719 firmware based on the [Ortega](https://github.com/hlandau/ortega/blob/master/rtg-spec.md) specification.
The firmware has been tested on the [Talos II](https://wiki.raptorcs.com/wiki/Talos_II) by [Raptor Computer Systems](https://www.raptorcs.com/).
**Note: This firmware is currently in development. Flashing the firmware to a network card can result in a bricked device when either an external programmer is required, or the external flash must be temporarily disabled during boot-up.**
## Requirements
This repository depends on a number of external tools
- Customized LLVM/Clang compiler for MIPS firmware
- CMake 3.5.1+
- Linux (utilities)
- Clang Format (optional)
- Flexelint/PCLint+ (optional)
- IPXact generator (optional)
## Status
- Libraries:
- MII Library: Done
- NVRAM Library: Done
- Stage1
- Implementation: Functional
- Testing: Minimal, WIP
- Stage2
- Implementation: Merged with Stage1, functional
- VPD: Not started
- WOL: Not started
- APE
- Implementation in progress
- Utilities
- Firmware tool: Functional
- Register tool: Functional
- APE Tool: In progress
## Compiling
To compile the firmware, the following command sequence can be used:
```bash
mkdir build
cd build
cmake .. -G Ninja
cmake --build .
```
