我无法使用arduino IDE和USB线将任何程序上传到我的arduino。
当我尝试时，它会显示avrdude: stk500v2_ReceiveMessage(): timeout
我搜索了所有网络并查看了avrdude: stk500v2_ReceiveMessage(): timeout之类的问题，但当我尝试上传程序时，我的arduino并没有眨眼。
我使用RasberryPi和arvdude制作了一些东西来再次刷新引导加载程序。 Here are some pictures of my setup.
我正在使用此命令：
sudo avrdude -p atmega2560 -C ~/avrdude_gpio.conf -c pi_1 -v -U flash:w:stk500boot_v2_mega2560.hex:i
以下是我尝试的输出：

一切看起来都不错，但是当我将它重新连接到我的电脑（在Linux上）时，我无法上传任何程序。
正确检测到电路板，如/ dev / ttyACM0。当我从工具菜单中Get board info时，这是输出

我做错了什么？
