NIOS II program flash 错误请教
目标板和工程都建完后开始用NIOS II IDE下载,但出现如下错误:
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
之后,我去掉了sysid和TIME0 ,再次编译下载,又出现如下错误:
Using cable "ByteBlasterII [LPT1]", device 1, instance 0x00
Pausing target processor: OK

有遇到过类似问题的么,请指教.
看上去是你的CPU没有启动起来亚，估计你做的nios的SOC有问题，最好使用他的ref的例子的基础上修改你的设计。一步一步的添加进去
我修改了reset和 exception为指向ON CHIP RAM 后 错误变为：
Processor is already paused

请大家帮忙
我已经卡了快一个月了
哭~
1、可以重新编译硬件后，重新下载硬件配置文件；
2、将不用的管脚设置为as input tri-stated；
3、查看存储器的相关时钟。
