上面是CPU1的内存分布和调用IPC的例程，使用IPC_sendcommand可以设置寄存器，但是CPU2的IPC0中断无法启动

你好，CPU2的中断是怎么设置的？以及，你是基于哪个TI例程修改的呢?

0 ?? ? 3 年多前回复 Green Deng

你好，cmd是pfc vienna例程中的，ipc的例程是参考了C2000 Academy 中的28377的IPC lab,cpu2的中断设置为：

void main(void)
{
    // Configure system clock and PLL, enable peripherals, and configure
    // flash if used.
    Device_init();

    // Initialize the PIE module and vector table.
//    Interrupt_initModule();
//    Interrupt_initVectorTable();

    Interrupt_initModule();
    Interrupt_initVectorTable();

    // Clear any IPC flags if set already
    IPC_clearFlagLtoR(IPC_CPU2_L_CPU1_R, IPC_FLAG_ALL);

    // Enable IPC0 interrupt.
    IPC_registerInterrupt(IPC_CPU2_L_CPU1_R, IPC_INT0, ipc0_ISR);

    // Enable global interrupts.
    EINT;
    // Enable real-time debug.
    ERTM;

    // Synchronize both the cores.
    IPC_sync(IPC_CPU2_L_CPU1_R, IPC_FLAG17);


    for (;;) {
        // Do nothing.
        NOP;
    }
}

interrupt void ipc0_ISR(void)
{
    uint32_t cmd, addr, data;
//    num = 4824;
    // Clear interrupt flags.
    Interrupt_clearACKGroup(INTERRUPT_ACK_GROUP1);

    // Read the data from the IPC registers.
    num = IPC_readCommand(IPC_CPU2_L_CPU1_R, IPC_FLAG0, false, &cmd, &addr, &data);

    // Acknowledge IPC1 flag from remote.
    IPC_ackFlagRtoL(IPC_CPU2_L_CPU1_R, IPC_FLAG0);
   //
    J[0] = cmd;
    J[1] = addr;
    J[3] = data;

你好，是否有尝试过 C2000Ware 中提供的 C2000 Academy 解决方案？那边工程师的意思是可以先尝试C2000Ware中的解决方案，并检查是否适用。

IPC lab的解决方案可在以下位置获得：
