[問題] Altera SOPC中使用DDR SDRAM的問題
小弟最近用SOPC加入DDR SDRAM controller後，遇到下面的error
Error: IO_PIN atom "ddr_dqs_to_and_from_the_ddr_sdram_0[1]" has port
DQSUPDATEEN that must be connected to the dqsupdate output of a DLL because
the dqs_ctrl_latches_enable parameter is set to true
Error: IO_PIN atom "ddr_dqs_to_and_from_the_ddr_sdram_0[0]" has port
DQSUPDATEEN that must be connected to the dqsupdate output of a DLL because
the dqs_ctrl_latches_enable parameter is set to true
我已經在Assignements\Settings\Device\Device and Pin Options\Dual Purpose Pins
把所有的IO設為Use as regular I/O....
我用的板子是Altera的 2S60ROHS Nios II Development Kit
請問有人知道怎麼解決這error嗎??
