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.
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
The custom Application is located in the apps directory, and you can build it through the make tool. For example:
gmake apps/helloworld/install # build and deploy helloworld app
gmake apps/bsdinfo/install # build and deploy bsdinfo app
gmake #Repackage images- Get the latest version of BouffaloLab DevCube from http://dev.bouffalolab.com/download
- Follow the steps in the picture below:
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
#
- Adapt to the native serial port driver instead of using the functions provided by OpenSBI.
- Port rpmsg-lite to kernel. (Establish communication with RTOS core) (Done)
- Enable net80211 wireless protocol stack.
- Porting Matter.
- Porting the LVGL graphics library and other peripherals.
- 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.
