忘记配置LPDDR4的参数 导致系统编译的时候报错:Error(14566): The Fitter cannot place 4 periphery component(s) due to conflicts with existing constraints (4 BYTE(s)). Fix the errors described in the submessages, and then rerun the Fitter. The Intel FPGA Knowledge Database may also contain articles with information on how to resolve this periphery placement failure. Review the errors and then visit the Knowledge Database at https://www.intel.com/content/www/us/en/support/programmable/kdb-filter.html and search for this specific error message number.
Error(175001): The Fitter cannot place 1 BYTE, which is within Generic Component soc_system_emif_io96b_hps_0.
