Get Started
You can freely download BM1880 BSP/SDK package and demo programs at Sophon BM1880 GitHub https://github.com/BM1880-BIRD/ .
In following sections, we will guide you how setup hardware and software environment, and how to build and run demo programs. Please check Sophon BM1880 GitHub for more information.
Setup Neural Network Module
Setup Neural Network Module by the steps provided below.
Step 1: Preparation
Before you start, make sure you have the following:
Host PC with Ubuntu 18.04 operation system & OpenCV 3.4.0 & Python 2.7 & Python 3 & libusb & libgoogle-glog
Neural Network Module with USB cable
Serial communication program (minicom) at host PC
Step 2: Hardware Installation
Step 2.1: Connect NNM and host PC with USB cable
Connect NNM to host PC via USB type A interface, host PC will identify NNM automatically, it will generate one USB device node named /dev/ttyACM0 if connection succeed. You can check it by below command:
Copy $ ls -al /dev/ttyACM0
Copy crw-rw---- 1 root dialout 166, 0 十二 12 18:03 /dev/ttyACM0 Install pyusb on host PC. It will download image to NNM by python script later.
Copy $ sudo apt-get install python-pip
$ pip install pyusb
Note (Ubuntu18.04 ONLY, JUST DO IT ONCE):
Please
1. Add Bitmain USB PID/VID to filter list of modem manager using the following command:
Copy sudo vim /lib/udev/rules.d/78-mm-whitelist-internal-modem.rules
Copy ACTION!="add|change|move", GOTO="mm_whitelist_internal_modem_end"
ATTRS{idVendor}=="30b1", ATTRS{idProduct}=="1000", ENV{ID_MM_DEVICE_IGNORE}="1"
LABEL="mm_whitelist_internal_modem_end"
ACTION!="add|change|move", GOTO="mm_whitelist_internal_modem_end"
ATTRS{idVendor}=="30b1", ATTRS{idProduct}=="1001", ENV{ID_MM_DEVICE_IGNORE}="1"
LABEL="mm_whitelist_internal_modem_end"
ACTION!="add|change|move", GOTO="mm_whitelist_internal_modem_end"
ATTRS{idVendor}=="30b1", ATTRS{idProduct}=="1003", ENV{ID_MM_DEVICE_IGNORE}="1"
LABEL="mm_whitelist_internal_modem_end"
ACTION!="add|change|move", GOTO="mm_whitelist_internal_modem_end"
ATTRS{idVendor}=="0559", ATTRS{idProduct}=="1000", ENV{ID_MM_DEVICE_IGNORE}="1"
LABEL="mm_whitelist_internal_modem_end"
Copy sudo udevadm control --reload Or
2. Stop modem manager
Copy sudo systemctl stop ModemManager.service Or
3. Disable modem manager (permanently) to avoid it restarting after a reboot
Copy sudo systemctl disable ModemManager.service Step 2.2: Plug UART cable to NNM
To show messages from NNM, plug UART cable to NNM as below. And then connect USB-to-UART cable to host PC.
Setup Com port with below configurations:
115200-8-N-1 no hardware flow control
Step 2.3: Plug USB cable to NNM
Step 3: Build image for NNM
Go to https://github.com/BM1880-BIRD/bm1880-system-sdk and follow the README to build image on host PC for NNM.
Step 4: Download image to NNM
Now we can start to download image to BM1880 USB module.
Copy $ cd bm1880/bm1880-system-sdk/install/soc_bm1880_asic_nnm/bm1880_emmc_dl_v1p1
$ sudo python bm1880_emmc_download.py It will show:

Build and Run Demo Program
We prepares two demo programs for NNM.
Download source code
We will put demo source code in same folder as bm1880-system-sdk.
Get source code and bmodel by below command:
Copy $ cd bm1880
$ git clone https://github.com/BM1880-BIRD/bm1880-ai-demo-program.git ---
Face detection (MTCNN)
Device Requirement:
PC with Ubuntu 18.04 (capture image and display result)
Step 1: Build demo program
Demo source code is located in bm1880-ai-demo/rtsp_fd_fr.
Build binary for NNM:
Copy $ cd bm1880/bm1880-ai-demo-program/rtsp_fd_fr
$ cmake . -DAARCH64_TOOLCHAIN_BIN=/XXXXXX/bm1880/bm1880-system-sdk/host-tools/gcc/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/ -DPROGRAM=edge -DPLATFORM=soc_bm1880_asic -Bbuild/fdfr_soc
$ make -C build/fdfr_soc
Set AARCH64_TOOLCHAIN_BIN to proper path.
build binary for PC:
Copy $ cd bm1880/bm1880-ai-demo-program/rtsp_fd_fr
$ cmake . -DPROGRAM=host -DPLATFORM=cmodel -Bbuild/fdfr_host
$ make -C build/fdfr_host NNM program is rtsp_fd_fr/build/fdfr_soc/bin/test_libusb_fdfr.
PC program is rtsp_fd_fr/build/fdfr_host/bin/test_libusb_fdfr.
Step 2: Put NNM demo program and bmodel into image
To modify rootfs folder, we need to unpack emmc.tar.gz, and then unpack rootfs.tar.gz.
Copy $ cd bm1880/bm1880-system-sdk/install/soc_bm1880_asic_nnm/bm1880_emmc_dl_v1p1
$ tar xvf emmc.tar.gz
$ cd emmc_nnmc_pkg
$ tar xvf rootfs.tar.gz Copy test_libusb_fdfr and necessary bmodels to rootfs folder, and then pack emmc.tar.gz.
Copy $ cp -a ../../../../../bm1880-ai-demo-program/rtsp_fd_fr/build/fdfr_soc/bin/test_libusb_fdfr rootfs/
$ rm -rf rootfs.tar.gz
$ sudo tar zcvf rootfs.tar.gz rootfs
$ rm -rf rootfs
$ cd ..
$ rm -rf emmc.tar.gz
$ tar zcvf emmc.tar.gz emmc_nnmc_pkg
$ rm -rf emmc_nnmc_pkg Step 3: Re-download image to NNM
Download image to NNM again for updating rootfs
Copy $ cd bm1880/bm1880-system-sdk/install/soc_bm1880_asic_nnm/bm1880_emmc_dl_v1p1
$ sudo python bm1880_emmc_download.py emmc.tar.gz Re-plug NNM to start downloading. After finished, you can check in NNM's serial console by this:
Copy $ ls /test_libusb_fdfr Step 4: Run demo program (NNM)
In NNM's serial console, input commands below to start demo program:
Add a new configuration file:
Copy repository: /data/repository
# detector: one of {tinyssh, mtcnn}
detector: tinyssh
# detector_models: list of paths separated by |
detector_models: /system/data/bmodel/tiny_ssh.bmodel|/system/data/bmodel/det3.bmodel
extractor: bmface
extractor_models: /system/data/bmodel/bmface.bmodel
similarity_threshold: 0.6
facepose_model: /system/data/bmodel/light_rpoly_lmp_iter_75000_w_scale.bmodel Start program:
Copy $ ldconfig
$ cd /system/data
$ ./load_jpu.sh
$ ./load_npu_bm1880.sh
$ mdev -s
$ cd /
$ ./test_libusb_fdfr ./fdfr.conf Step 5: Run demo program (PC)
In PC's terminal, input commands below to start demo program:
Copy $ cd bm1880/bm1880-ai-demo-program/rtsp_fd_fr/build/fdfr_host/bin
$ sudo ./test_libusb_fdfr There will be a window showing the results of face detection.

Object detection (YOLOv3)
Device Requirement:
PC with Ubuntu 18.04 (capture image and display result)
Step 1: Build demo program
Demo source code is located in bm1880-ai-demo/rtsp_fd_fr.
Build binary for NNM:
Copy $ cd bm1880/bm1880-ai-demo-program/rtsp_fd_fr
$ cmake . -DAARCH64_TOOLCHAIN_BIN=/XXXXXX/bm1880/bm1880-system-sdk/host-tools/gcc/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/ -DPROGRAMS="yolo_nnm;libusb_inference_server" -DPLATFORM=soc_bm1880_asic -Bbuild/objdet_soc
$ make -C build/objdet_soc
Set AARCH64_TOOLCHAIN_BIN to proper path.
build binary for PC:
Copy $ cd bm1880/bm1880-ai-demo-program/rtsp_fd_fr
$ cmake . -DPROGRAMS="yolo_host" -DPLATFORM=cmodel -Bbuild/objdet_host
$ make -C build/objdet_host NNM program is rtsp_fd_fr/build/objdet_soc/bin/yolo_nnm.
PC program is rtsp_fd_fr/build/objdet_host/bin/yolo_host.
Step 2: Put NNM demo program and bmodel into image
To modify rootfs folder, we need to unpack emmc.tar.gz, and then unpack rootfs.tar.gz.
Copy $ cd bm1880/bm1880-system-sdk/install/soc_bm1880_asic_nnm/bm1880_emmc_dl_v1p1
$ tar xvf emmc.tar.gz
$ cd emmc_nnmc_pkg
$ tar xvf rootfs.tar.gz Copy yolo_nnm and necessary bmodels to rootfs folder, and then pack emmc.tar.gz.
Copy $ cp -a ../../../../../bm1880-ai-demo-program/rtsp_fd_fr/build/objdet_soc/bin/yolo_nnm rootfs/
$ cp -a ../../../../../bm1880-ai-demo-program/darknet-yolov2-object-classification-v2/darknet/models/bmnet/yolov3_1_3_608_608.bmodel rootfs/system/data/bmodel/
$ rm -rf rootfs.tar.gz
$ sudo tar zcvf rootfs.tar.gz rootfs
$ rm -rf rootfs
$ cd ..
$ rm -rf emmc.tar.gz
$ tar zcvf emmc.tar.gz emmc_nnmc_pkg
$ rm -rf emmc_nnmc_pkg Step 3: Re-download image to NNM

$ sudo python bm1880_emmc_download.py emmc.tar.gz Re-plug NNM to start downloading. After finished, you can check in NNM's serial console by this:
Step 4: Run demo program (NNM)
In NNM's serial console, input commands below to start demo program:
Copy EX. yolo_nnm <bmodel_path> <bmodel_name> <yolov2 | yolov3> Start program:
Copy $ ldconfig
$ cd /system/data
$ ./load_jpu.sh
$ ./load_npu_bm1880.sh
$ mdev -s
$ cd /
$ ./yolo_nnm /system/data/bmodel yolov3_1_3_608_608.bmodel yolov3 Step 5: Run demo program (PC)
In PC's terminal, input commands below to start demo program:
Copy $ cd bm1880/bm1880-ai-demo-program/rtsp_fd_fr/build/objdet_host/bin
$ sudo ./yolo_host There will be a window showing the results of face detection.
