can't find byte stream device

HI ：

when I download nios xxx.elf,it is error ,because mismatch the system ID and system timestamp.but I am sure I do it ,and I download the xxx.sof through JTAG ,and view in the signtop ,it is sucessful.

I compiler the software(Hello word) is sucessful ,but debug configtion is error ,

there is nothing in the "byte stream device",when I ignore system ID and system timestamp it is failed to download.

the log :

Connected system timestamp not found on target at expected base address.

Connected system ID hash not found on target at expected base address.

and so on .......

how can I do ?

I creat new porject or creat new SOPC ,but it is the same.

thank you
