TI中文支持网使用C6678例程中IPC中断，改为C6657 ipc中断时出现错误。代码如下：错误现象是：
打印输出为：
[TMS320C66x_0] Set interrupt from Core 0 to Core 1, cycle = 15268
[TMS320C66x_1] CORE1 test passed!
[TMS320C66x_0] Interrupt Info 16
正常还应有以下代码中红色部分，但是没有。从现象看是应该core1没有接收到core0的中断。
求帮忙解答，十分感谢！！！！！

Andy Yin1：
6657与6678的区别在于IPCRegister address，及IPC中断事件号不一致，请查看6657 user guide确认相关寄存器地址及中断事件号的变更。

我也是在做C6657的IPC中断，刚从6678样例修改移植到6657，分享给你

请问有6618 或者6670的嘛
