下载程序出错

openmmoo

自己做的最小系统,以前经常出现下面的错误，现在完全不能烧程序了。
Binary sketch size: 944 bytes (of a 7,168 byte maximum) - 13% used
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.

烧bootloader也提示如下：
processing.app.debug.RunnerException

重新做了一个最小系统还是不行，请高手指点

检查你的ISP下载器和arduino的连接是否正确，可以参考论坛里的USBASP的帖子

经查rest没有接好，修复后，还是不能下！实在找不到问题了！
