Error handling 为什么我不能把草图上传到我的黑板上？

我使用的是Roboduino板，每当我上传闪烁草图时，我都会遇到以下错误。我已经用了好几天了。但问题从现在开始就出现了

-我已经选择了正确的董事会-Arduino Duemilanove或ATmega 328与我的工作从长回来

-我正在使用正确的串行端口COM4。我已卸下电缆并重新连接，以确认端口仅为COM4

-我已移除与电路板针脚0的所有连接，针脚1现在可用

有什么问题吗？如何解决这个问题

我遇到的错误是

这是一个糟糕的Arduino克隆，我想电路板没有被重新设置，或者连接不好。尝试选择Arduino UNO，因为车载ATmega328p可能正在使用optiboot引导加载程序。

1。尝试手动重置电路板，然后突然单击arduino ide 2上的上载。你有另一块板子吗？尝试将另一个mega328p替换到此板。我想这个mega328p上的引导程序坏了或者芯片不见了。因为在将电路板连接到pc时，您可以看到com端口。
