TMS320F28377D双核CPU2无法运行

你要调节到CPU1，CPU2 standalone的configuration。这时候CPU1例程的红色区域是被打开的。

void main(void)
{
// Step 1. Initialize System Control:
// PLL, WatchDog, enable Peripheral Clocks
// This example function is found in the F2837xD_SysCtrl.c file.
InitSysCtrl();

#ifdef _STANDALONE
#ifdef _FLASH
// Send boot command to allow the CPU2 application to begin execution
IPCBootCPU2(C1C2_BROM_BOOTMODE_BOOT_FROM_FLASH);
#else
// Send boot command to allow the CPU2 application to begin execution
IPCBootCPU2(C1C2_BROM_BOOTMODE_BOOT_FROM_RAM);
#endif
#endif

// Call Flash Initialization to setup flash waitstates
// This function must reside in RAM
#ifdef _FLASH
InitFlash();
#endif

// Step 2. Initialize GPIO:
// This example function is found in the F2837xD_Gpio.c file and
// illustrates how to set the GPIO to it's default state.
InitGpio(); // Skipped for this example
EALLOW;
GpioCtrlRegs.GPADIR.bit.GPIO31 = 1;
GPIO_SetupPinOptions(34, GPIO_OUTPUT, GPIO_PUSHPULL);
GPIO_SetupPinMux(34, GPIO_MUX_CPU2, 0);
//TODO Add code to allow configuration of GPADIR from CPU02 using IPC
EDIS;
GpioDataRegs.GPADAT.bit.GPIO31 = 1;// turn off LED
// Step 3. Clear all interrupts and initialize PIE vector table:
// Disable CPU interrupts
DINT;

// Initialize the PIE control registers to their default state.
// The default state is all PIE interrupts disabled and flags
// are cleared.
// This function is found in the F2837xD_PieCtrl.c file.
InitPieCtrl();

// Disable CPU interrupts and clear all CPU interrupt flags:
IER = 0x0000;
IFR = 0x0000;

// Initialize the PIE vector table with pointers to the shell Interrupt
// Service Routines (ISR).
// This will populate the entire table, even if the interrupt
// is not used in this example. This is useful for debug purposes.
// The shell ISR routines are found in F2837xD_DefaultIsr.c.
// This function is found in F2837xD_PieVect.c.
InitPieVectTable();

// Enable global Interrupts and higher priority real-time debug events:
EINT; // Enable Global interrupt INTM
ERTM; // Enable Global realtime interrupt DBGM

// Step 6. IDLE loop. Just sit and loop forever (optional):
for(;;)
{
//
// Turn on LED
//
GpioDataRegs.GPADAT.bit.GPIO31 = 0;
//
// Delay for a bit.
//
DELAY_US(1000 * 500);

//
// Turn off LED
//
GpioDataRegs.GPADAT.bit.GPIO31 = 1;
//
// Delay for a bit.
//
DELAY_US(1000 * 500);
}
}

我把这个定义#ifdef _STANDALONE
#ifdef _FLASH去掉了  直接写的IPCBootCPU2(C1C2_BROM_BOOTMODE_BOOT_FROM_FLASH);可以吗

可以，效果是一样的。

可是CPU2的程序无法加载，点击DEBUG后会出现如下错误提示：C28xx_CPU2: Error setting the GSxMSEL register for Flash operations

CPU2也要调到FLASH模式。

我在CPU2里面加了这句IPCBootCPU2(C1C2_BROM_BOOTMODE_BOOT_FROM_FLASH);还是会出现C28xx_CPU2: Error setting the GSxMSEL register for Flash operations的错误提示

另外官方例程的CPU2程序里并没有加IPCBootCPU2(C1C2_BROM_BOOTMODE_BOOT_FROM_FLASH);这句话，当然官方例程是在RAM里运行的，但也没有配置IPCBootCPU2(C1C2_BROM_BOOTMODE_BOOT_FROM_RAM

您好请问您找到问题所在了么？我现在也卡在CPU2FLASH无法运行这里了，官方例程烧进CPU里只有CPU1断电能正常运行，CPU2无法正常运行，经过各种分析判断问题出在库函数IPCBOOTCPU2（C1C2_BROM_BOOTMODE_BOOT_FROM_FLASH）这句没有运行正确，单步调试发现该函数返回值正常，但查看寄存器里BOOTCPU2并没有被置位

跟代码、库函数都没有关系，试试下面的方式来load：

1) Launch the target configuration from the Target configurations window (View -> Target Configurations -> Right click on the F28377D ccxml -> Launch selected configuration)

2) Connect to CPU1 and then to CPU2 (In the debug window, select the C28xx_CPU1, right click -> Connect Target. Do the same thing for C28xx_CPU2).

3) Load the code in CPU2 (Select C28xx_CPU2 and then in the debug window menu click on "Run" -> Load -> Load program and choose the .out file that you want to load in to CPU2)

请问你解决了吗

这样有效果
