TI中文支持网TI工程师您好，我使用的芯片是C6678，目前在做的是SPI NOR Flash烧写，程序烧写进去后，改到spi boot方式，上电之后，SPI clk为590KHz，程序加载完成后，连接JTAG，发现core0-core3有启动，core4-core7没有启动，程序还是运行在RBL中，boot部分程序如下，加在主核初始化后，请问这是什么可能原因？

Shine：
core4-core7的启动流程和core1~core3一样的。检查一下core0有没有发IPC中断来唤醒core4~core7。
建议先测试core0+core4，看core4能不能起来。

shine，我的主核启动从核部分程序就是我题中描述的那样，core1-core7的都是一样的，core0有给所有从核发中断，
