总是<br />“Error: The instruction register length for the EPM1270T144 device at position 1 in the JTAG chain is unknown”<br />断电下载时,开始正常,中间有时<br />“Error: Can't Verify device number 1”<br />有时成功。<br />有知道原因的吗??<br /><br /><br />另,时钟信号怎么定义才不会告警<br />“ Info: Assuming node "clk" is an undefined clock”<br /><br /><br />谢谢! |
