大哥大姐,我也遇见这个问题,一直解决不掉,急死了。 我仔细阅读了论坛里的其它相关帖子,才猛然发现,我把数据总线的传输方向置为输出output了,改成双向bidir就可以了!不知道您说的数据总线的传输方向是哪个地方的?难道是flash? 下面是我 的出错,请我看看怎么解决。万分感谢!! #! /bin/sh # # This file was automatically generated by the Nios II IDE Flash Programmer. # # It will be overwritten when the flash programmer options change. # cd D:/mychengxv/MYFPGA/flash/software/hello_world_0/Debug # Creating .flash file for the FPGA configuration $SOPC_KIT_NIOS2/bin/sof2flash --offset=0x000000 --input=D:/mychengxv/MYFPGA/flas h/flash_time_limited.sof --output=flash_time_limited.flash Info: ******************************************************************* Info: Running Quartus II Convert_programming_file Info: Command: quartus_cpf --no_banner --convert D:/mychengxv/MYFPGA/flash/flash _time_limited.sof flash_time_limited.rbf File D:/mychengxv/MYFPGA/flash/flash_time_limited.sof contains one or more time- limited megafunctions that support the OpenCore Plus feature that will not work after the hardware evaluation time expires.
