TMS320F28377D: 想请教一个问题，为什么我的双核程序下载到FLASH里面，仿真的时候两个CPU挨个运行就可以运行程序，但是重新上电之后就运行不了。不知道是不是CPU2没有启动起来，这个咋办呢

您好，      

请参考双核LED示例led_ex1_blinky ，允许CPU01主系统启动CPU02控制系统：

device_bootCPU2 (C1C2_brom_bootmode_boot_from_flash)；

c2000ware多核开发指南7. Examples from C2000ware — C2000 Multicore Development Guide

我用device_bootCPU2 (C1C2_brom_bootmode_boot_from_flash)；启动不了CPU2，用IPC_setBootMode(IPC_CPU1_L_CPU2_R, C1C2_BROM_BOOTMODE_BOOT_FROM_FLASH);可以启动，但是就是会出现我标题里面的问题。我的CPU1代码如下：
