Himax allon_sensor_tflm_freertos example for Seeed Grove Vision AI Module V2

How to build the firmware?

This part explains how you can build the firmware for Grove Vision AI Module V2. Note: The following has been tested to work on Ubuntu 20.04 PC

• Step 1: Install the following prerequisites

  sudo apt install make
  

• Step 2: Download Arm GNU Toolchain (arm-gnu-toolchain-13.2.rel1-x86_64-arm-none-eabi.tar.xz)

  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
  

• Step 3: Extract the file

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

• Step 4: Add arm-gnu-toolchain-13.2.Rel1-x86_64-arm-none-eabi/bin/: to PATH

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

• Step 5: Compile the firmware

  cd EPII_CM55M_APP_S
  

  You need to change the path inside the makefile to the path of the compiler. Such as:

  GNU_TOOLPATH ?= /mnt/c/Users/mengd/Desktop/arm-gnu-toolchain-13.2.Rel1-x86_64-arm-none-eabi/bin/
  

  Then,

  make clean
  make
  

• Output elf file: ./obj_epii_evb_icv30_bdv10/gnu_epii_evb_WLCSP65/EPII_CM55M_gnu_epii_evb_WLCSP65_s.elf
• Step 6: Generate firmware image file

  ./output.sh
  

• Output firmware image: ./output_case1_sec_wlcsp/output.img
