20230313 linux点亮led

原理图

使用SysConfig ，设置pinctrl

设置相关输出/上拉
得到相关PIN的设备树设置

更改设备树

在/home/gaojie/software/linux_sdk81/board-support/linux-5.10.65+gitAUTOINC+dcc6bedb2c-gdcc6bedb2c/arch/arm64/boot/dts/ti/k3-j721e-sk.dts 中

&main_pmx0 添加
	led_gpio_pins_default: led_gpio_pins_default { 		pinctrl-single,pins = < 			J721E_IOPAD(0x104, PIN_INPUT_PULLUP, 7) /* (AD28) PRG0_PRU1_GPO1.GPIO0_64 */ 		>; 	};

在/节点添加
	leds { 		#address-cells = <1>; 		#size-cells = <0>; 		compatible = "gpio-leds"; 		pinctrl-names = "default"; 		pinctrl-0 = <&led_gpio_pins_default>; 		led-gpio = <&main_gpio0 64 GPIO_ACTIVE_HIGH>; 	};

make linux-dts make linux-dts_install

修改 /home/gaojie/software/linux_sdk81/Rules.make

export DESTDIR = /home/gaojie/software/linux_sdk81/_linux_install

在/proc/device-tree可查看到leds 添加相关驱动，编译成Ko

https://blog.csdn.net/kelsel/article/details/52758278

/home/gaojie/software/linux_sdk81/board-support/linux-5.10.65+gitAUTOINC+dcc6bedb2c-gdcc6bedb2c/drivers/char/Makefile

直接添加相关ko，也可以配置

添加相关*.c，在/home/gaojie/software/linux_sdk81 make linux

app 应用层

202303添加USB摄像头

使用balenaEtcher 下载安装好sdk82的image sudo minicom -D /dev/ttyUSB2 -c on 登录相关串口，必须在 /opt/edge_ai_apps 执行 ./setup_script.sh

检查usb摄像头

source ./init_script.sh

#Check for USB Camera ls /dev/v4l/by-path/*usb*video-index0 > /dev/null 2>&1 if [ "$?" == "0" ]; 
then     USB_CAM_DEV=`ls /dev/v4l/by-path/*usb*video-index0 | head -1 | xargs readlink -f`    
echo "USB Camera detected"    
echo "    device = "$USB_CAM_DEV     
echo "    format = jpeg" 
fi

保存一张usb 图片 v4l2-ctl –device /dev/video2 –set-fmt-video=width=1280,height=720,pixelformat=MJPG –stream-mmap –stream-to=/home/root/software/video0-output.jpg –stream-count=1

摄像头图像获取并显示 gst-launch-1.0 v4l2src device=/dev/video2 ! image/jpeg,width=1280,height=720,framerate=30/1 ! jpegdec ! videoconvert ! autovideosink
