关于C6678 IPC中断疑问

应用场景:在6678EVM板上多核并行执行算法,由Core0触发IPC中断发送同步执行信号,Core1~Core7接收该中断执行算法。

问题:Core0已经通过写了IPCGR1~IPCGR7寄存器触发IPC中断(中断源id分别为1~7),但是有其他内核(Core1~Core4)已经成功接收到IPC中断,但是Core5~Core7并未接收到IPC中断,通过查看地址(0x02620240和0x02620280)各内核的IPCGR和IPCAR寄存器的值,表明IPC中断源已经成功设置,但是Core5~Core7确实没被触发IPC中断。

附件内容是触发IPC中断的函数

请求各路大神帮忙解答疑惑,谢谢!!!
