能在DSP的片内Flash调试程序吗？
使用TMS320F2812，不想外扩RAM了，片内有128K flash，请问一下能直接使用片内调 试程序吗？马达控制程序有多大，片内flash能存储得了吗？ 我用STM32VC5416的，程序小，从来不外扩RAM
2812没用过，但我觉得只要你的程序放的下，肯定可以啊 看了你的另一片帖子，我觉得应该改一下
程序要烧在ram里 程序一般在RAM中调试，
我的意思是如果RAM不够的话，可以烧写进Flash，在Flash中调试吗？
好像不能吧。程序运行必须要在RAM中。 因为我用的DSP没有内置flash，我不敢打包票
不过我觉得只要空间够，内置的flash与外置的flash没差别
你只要确认一下内置的flash是否是程序空间即可（区别于数据空间与IO空间）
你可以在datasheet中确认一下，也可以实测一下 2812可以在Flash中调试程序，不太方便的是断点太少，另外还要经常烧录Flash，可能会因意外烧死Flash，调试速度也偏慢，如果可以，可以在RAM中调试好在转到Flash中，前提是你的程序不要太大，否次因为RAM容量限制，无法完全在RAM中调试运行 cmd文件如下所示/*

Flash中直接运行，速度很慢
