編譯Openmv固件&增加串口

編譯官方板子的固件

克隆倉庫到本地

git clone --recursive https://github.com/openmv/openmv.git

Openmv項目中有很多子模塊，務必加上recursive參數，這樣才會一並把子模塊下載下來。

安裝Docker

過程不表，網上已有許多完善的教程

編譯

git clone https://github.com/openmv/openmv.git --depth=50
cd openmv/docker
make TARGET=<TARGET NAME>

下面是可選的固件
make TARGET=OPENMV2 # To build the OpenMV Cam M4 Firmware
make TARGET=OPENMV3 # To build the OpenMV Cam M7 Firmware
make TARGET=OPENMV4 # To build the OpenMV Cam H7 Firmware (default)
make TARGET=OPENMV4P # To build the OpenMV Cam H7 Plus Firmware
make TARGET=OPENMVPT # To build the OpenMV Pure Thermal Firmware
make TARGET=PORTENTA # To build the Arduino H7 Portenta Firmware
make TARGET=NANO33 # To build the Arduino Nano 33 BLE Firmware 

編譯WeAct的板子

克隆倉庫到本地

git clone https://github.com/WeActTC/openmv/tree/WeActStudio 
#這里先不下載子模塊，因為這個庫里有個子模塊是死活下載不下來的

git checkout -b WeActStudio origin/WeActStudio  
#切換到WeActStudio分支

cd openmv
git submodule init
git submodule update --depth=1
cd src/micropython
git submodule init
git submodule update --depth=1
cd ..
#下載子模塊

安裝依賴

Weact的倉庫中暫時沒看到支持Docker一鍵編譯，手動安裝以下依賴

sudo apt-get remove gcc-arm-none-eabi
sudo apt-get autoremove
sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa
sudo apt-get update
sudo apt-get install gcc-arm-embedded
sudo apt-get install libc6-i386
sudo apt-get install python2.7 python-dev python-pip
sudo apt-get install libusb-1.0-0 libusb-1.0-0-dev
sudo apt-get install python-gtksourceview2
sudo pip install numpy pyserial==2.7 pyusb==1.0.0b2 Pillow
sudo apt-get install git
sudo apt-get install make

編譯

Weact的板子支持兩種固件，一種直接運行在芯片內部flash，另一種運行在QSPI的flash。下面編譯的是直接運行在芯片內部flash的固件。另一種沒測試，理論上只需修改 為WeActStudioSTM32H7xx_QSPI即可。

cd src/micropython/mpy-cross
make

cd ../../
make TARGET=WeActStudioSTM32H7xx

修改IO&添加串口

主要修改 /micropython/ports/stm32/boards/WeActStudioSTM32H7xx/mpconfigboard.h和

micropython/ports/stm32/boards/WeActStudioSTM32H7xx/pins.csv這兩個文件

修改IO

pins.csv里面定義了IO，自行修改即可

添加串口五

在mpconfigboard.h中添加串口五的定義

// UART1 config
#define MICROPY_HW_UART1_TX  (pin_A9)
#define MICROPY_HW_UART1_RX  (pin_A10)
/******************這是添加的部分***********/
// UART5 config
#define MICROPY_HW_UART5_TX  (pin_B13)
#define MICROPY_HW_UART5_RX  (pin_B12)
/******************這是添加的部分***********/
// UART3 config
#define MICROPY_HW_UART3_TX  (pin_B10)
#define MICROPY_HW_UART3_RX  (pin_B11)
#define MICROPY_HW_UART3_RTS (pin_B14)
#define MICROPY_HW_UART3_CTS (pin_B13)
