Error:"Connected system ID hash not found on target at expected base address"

Hi @vietvu1912,

Apologies for the delay, if i understand correct you have downloaded the sample design from intel and removed the TSE IP, and are having issues in running in Nios.
If the IP are removed from the platform design, would suggest to check also on the quartus rtl part and remove the relevant section, and that should work after recompiling and program the board with the sof.

Just to ensure that the design example downloaded are not corrupted, would also suggest to build and compile without changes and running it in nios.
Please do let us know if that helps to clarify.

Best Wishes
BB
