哪位坛友给我点提示,错误是哪方面的,该从哪方面入手.
我这几天按照站上的开源逻辑分析仪项目,投板做了一个板子.给芯片下载程序的时候,显示有错误.
pcb改动 : 邮购部没货了,自己和同事一起画板做了一个.为了适合铝制外壳,改动了布局和管脚分配.
原理图改动 :IO除第57脚的clk外,全部重新分配了引脚.
操作过程 : 将现在的管教连接将.ucf文件中对应的管脚名更改后,重新编译并生成.bit文件.之后在iMPACT中,"program fpga only" 能够成功,但是"Program flash and fpga"在进行到中间的时候出错.应该是在"verify"阶段.单独"verify"也会出错.
下面是"Program flash and fpga"后的显示信息:
