# FreeBSD IoT Project
The FreeBSD IoT Project is a research project that hopes to provide a business-friendly IoT standard solution based on FreeBSD's ultimate stability, security and complete ecology.

# Supported Boards
- [Sipeed M1s Dock](https://wiki.sipeed.com/hardware/zh/maix/m1s/m1s_dock.html)

## Quick Start
### Environment setup
Currently **ONLY** FreeBSD environment is supported. You can use software such as Virtual Box to install FreeBSD 13.2 or higher.

```
# pkg update
# pkg install git gmake liblz4 u-boot-tools riscv64-none-elf-gcc cmake ninja
# git clone --recursive git@github.com:Virus-V/freebsd-bl808.git
# cd freebsd-bl808
# gmake
```
*NOTE*: **FreeBSD requires root permissions to deploy rootfs, so the build process needs to be carried out with root permissions.**

BL808 FreeBSD firmware is in the `out` directory: `bl808_rtos_m0.bin` and `bl808_freebsd_d0.bin`
```
out
├── bl808_freebsd_d0.bin
└── bl808_rtos_m0.bin

1 directory, 2 files
```

### Build Customer Applications
The custom Application is located in the `apps` directory, and you can build it through the make tool. For example:
```bash
gmake apps/helloworld/install # build and deploy helloworld app
gmake apps/bsdinfo/install # build and deploy bsdinfo app

gmake #Repackage images
```

## Download Firmware
1. Get the latest version of BouffaloLab DevCube from http://dev.bouffalolab.com/download
2. Follow the steps in the picture below:

![FlashTool](https://raw.githubusercontent.com/Virus-V/freebsd-bl808/master/assets/BLDevCube_d0iDVi4UwD.png "Program BL808")

After the burning is completed, reset the board and you can see the following log, which means FreeBSD is running successfully.

The power to serve

#
```

# TODOs
1. Adapt to the native serial port driver instead of using the functions provided by OpenSBI.
2. Port rpmsg-lite to kernel. (Establish communication with RTOS core) (Done)
3. Enable net80211 wireless protocol stack.
4. Porting Matter.
5. Porting the LVGL graphics library and other peripherals.
6. Design rpmsg-lite bus driver, the rpmsg-lite bus driver is designed as a common component of the system to allow E907 to better provide services to C906.
