K2GICE板卡无故出现报错



在DSP端跑裸机代码,都跑的好好的,有时进调试模式时,CCS要报错,如下:

C66xx: Trouble Reading Memory Block at 0x74c81514 on Page 0 of Length 0x4: (Error -1202 @ 0x74C81514) Device core is hung. The debugger will attempt to force the device to a ready state to recover debug control. Your application's state will be corrupt. You should have limited access to memory and registers, but you may need to reset the device to debug further. (Emulation package 9.2.0.00002)

下面是进调试模式时弹出来的窗口

我另外用SDK做了一个SD启动卡,跑的linux,插上卡,能正常的进系统,串口调试助手那边显示都正确的。用JTAG进调试模式时,板子上的BOOT拨码开关我是打到第一个的,就是NO BOOT /EMULATION,这个咋回事啊,难道板子出问题了吗,好心疼,这是我的宝贝疙瘩啊,要哭了
