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.

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

Shine:

请试试重装一下CCS。

回复 Shine:

我把板子断电放一会儿,自己又好了

Shine:

回复 user18914063:

是不是温度太高了,散热不好。

user18914063:

回复 Shine:

我也考虑过这个可能性,但感觉应该不是,刚我把CCS10卸载了,重新安装,又出现这情况了,CPU温度很低的

user18914063:

回复 user18914063:

哦,忘了说了,板子上自带XDS100V2仿真器,但下载会有些慢,我就外接了XDS220U,和这个有关系吗,刚我把XDS220U断开了,用板载调试器,就又能进调试了,程序跑的好好的,那至少能说明板子是没问题的哈?

user18914063:

回复 user18914063:

好奇怪,板载调试器能用,然后我又把XDS220U接上,工程那边相应修改成XDS220U调试器,现在又可以用XDS220U进调试模式了,这情况比较反复无常的样子,感觉

Shine:

回复 user18914063:

外接XDS220U的话,板载XDS100会自动被disable掉。
