dsp2812 flash 固化后，在0x3d8000地址上已经改动了，为什么每次只有插上仿真器才能运行，试了好多天了，就有一次莫名其妙好使了，不插仿真器也好使，现在怎么弄都不行？

请检查一下硬件配置，确定是否已经处于微控制器模式。

我的是学习开发板，硬件应该没问题，我昨天晚上也没弄啥，今天早上莫名其妙的就好使了。但是我重新下载以后又不好使了。真是奇怪了。

那可以实际测量一下MP/MC#引脚，看一下到底是不是低电平

我的这个引脚是接地的DGND,怎么弄才好那？

如果是低电平，那应该是可以启动的。

不知道你的程序是什么样的，你是不是应该使用一个最简单的小程序来测试，比如点亮一个LED来看看会不会有问题。

还是不行，真是莫名其妙的，
