运行Custom Istruction Tutorial的例子，出现以下问题：

Using cable "USB-Blaster [USB-0]", device 1, instance 0x00
Pausing target processor: not responding.
Resetting and trying again: OK
Reading System ID at address 0x00010848: FAIL
    ID value does not match: read 0xFFFFFFFF; expected 0x597F999F
    Timestamp value does not match: image on board is older than expected
    Read timestamp  7:59:59 1970/01/01; expected 11:41:38 2005/01/07
Leaving target processor paused

请问是什么原因？

用的是stratix的开发板，用USB Blaster下载，已经升级到niosII
运行用户定制指令的例子，直接在tutorials->Nios2_Custom_Instruction中的custom_instruction.sof上运行没有问题，但按照教程添加了定制指令编译下载后，运行ci_tutorial（重新编译过），出现以下问题：
