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)
