我使用avr下载器给atmga1280下载程序时，接上电源后，出现电压低于工作电压的问题
Failed to enter programming mode. ispEnterProgMode: Error status received: Got 0xc0, expected 0x00 (Command has failed to execute on the tool)

Unable to enter programming mode. Verify device selection, interface settings, target power, security bit, and connections to the target device.



请问是下载模式的问题吗？
