Deploying SSCMA Models on Grove Vision AI V2

This example is a deployment tutorial for models included in SSCMA on the Grove Vision AI V2 module.

To deploy SSCMA models on the Grove Vision AI V2, you need to first convert the models into quantized TensorFlow Lite format. After conversion with the Vela converter, you can deploy the models to the Grove Vision AI V2 module. SSCMA has added this feature in the export tool, allowing you to add the parameter --format vela during the export process to export Vela models. Once successfully exported, the remaining steps are consistent with SSCMA - Model Deployment.

Additionally, you can attempt to manually build the firmware to accommodate the model.

Building Firmware in Linux Environment

The following steps have been tested on Ubuntu 20.04 PC.

Install Dependencies

sudo apt install make

Download Arm GNU Toolchain

cd ~
wget https://developer.arm.com/-/media/Files/downloads/gnu/13.2.rel1/binrel/arm-gnu-toolchain-13.2.rel1-x86_64-arm-none-eabi.tar.xz

Extract the File

tar -xvf arm-gnu-toolchain-13.2.rel1-x86_64-arm-none-eabi.tar.xz

Add to PATH

export PATH="$HOME/arm-gnu-toolchain-13.2.Rel1-x86_64-arm-none-eabi/bin/:$PATH"

Clone the Following Repository and Enter the Seeed_Grove_Vision_AI_Module_V2 Folder

git clone --recursive https://github.com/HimaxWiseEyePlus/Seeed_Grove_Vision_AI_Module_V2.git 
cd Seeed_Grove_Vision_AI_Module_V2

Compile the Firmware

cd EPII_CM55M_APP_S
make clean
make

The output ELF file is located at /obj_epii_evb_icv30_bdv10/gnu_epii_evb_WLCSP65/EPII_CM55M_gnu_epii_evb_WLCSP65_s.elf.

Generate Firmware Image File

cd ../we2_image_gen_local/
cp ../EPII_CM55M_APP_S/obj_epii_evb_icv30_bdv10/gnu_epii_evb_WLCSP65/EPII_CM55M_gnu_epii_evb_WLCSP65_s.elf input_case1_secboot/
./we2_local_image_gen project_case1_blp_wlcsp.json

The output firmware image is located at ./output_case1_sec_wlcsp/output.img.

Flashing the Firmware

You can use the SSCMA Web Toolkit or Grove Vision AI V2's USB-to-serial tool to flash the firmware, or you can directly use the Xmodem protocol to flash the firmware.
