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

You shouldn't ignore the mismatch in system id and timestamp. If there is a mismatch, it means there is a problem with the hardware configuration. Are you sure the project compiled correctly and that there were no errors when configuring the FPGA? Are you sure you selected the correct .sof file when programming the FPGA? If you use cores you don't have the license for, then the generated .sof file will have a _time_limited suffix, so be sure you select the right one.
