我也DIY了一个XILINX USB下载线,按照论坛上提供的原理图。 按照论坛的顺序 先下载 eeprom的 XILINX_EEPROM.IIC 到24C02 , 然后连接下载线,并自动按照好了下载线,在设备管理器上显示的也和论坛上一样。
开始-运行-cmd 回车
输入 SET XIL_IMPACT_ENV_USB2_FORCE_CPLD_UPDATE=TRUE 回车
再输入 impact 回车

无法更新 CPLD程序。 那位高人指点一下,(xc2c256的CPLD程序是这么下载的吗?) 用的芯片是 cy7c68013-ac100 xc2c256vqg100-7i 之间的连接核对无误。
怎么会出现错误? 不得解。。。。 |
