这条指令是嵌入内存中去执行的 ,在软件仿真器中执行相应的指令后会在Console窗口打印出illegal opcode信息,为何在设计开发板中执行同样的指令就不会打印这个信息呢?

软件仿真器
是指simulator吗?
如何才能使在开发板中运行这条非法指令的时候也可以报出这个illegal信息呢?
什么指令?为什么有这样的需求?
你好,您可以在英文论坛发布这个问题吗?我没有企业邮箱,无法在英文论坛提问题。
我们没有提供非法操作码的具体列表,详细请查看请问论坛的回复。
We do not have a list of invalid opcodes for C6748 in the tools team.
We believe that the simulator is doing some sort of lookup of valid codes and when it does not get a match it reports that the opcode is illegal. That lookup is not straightforward. Also that simulator is very old, unsupported and I do not have access to the source.
