epm7128烧录请教!!!

用maxplus2形成的*.pof文件烧录epm7128slc84-7的时候出现
\"Device not found or socket is empty!\"的错误,是怎么回事?
编程电缆的驱动也已经装上了
用的是并口的编程电缆,maxplus2中选的是byteblaster方式
请高手指点!!!

电缆连接有问题。你的操作系统是什么？2000、xp是要装驱动的

安装下载电缆的驱动程序：ByteBlaster II, ByteBlasterMV & ByteBlaster Driver for Windows 2000
You must install the ByteBlasterMV?, ByteBlaster? II, or ByteBlaster download cable driver before you can use them to program devices with the Quartus? II software or MAX+PLUS? II software. MAX+PLUS II software version 10.1 and later supports Windows 2000.

You must have system administration (Administrator) privileges to install the ByteBlaster II, ByteBlasterMV, or ByteBlaster download cable drivers.

Driver Installation
Click on the Start menu, choose Settings, and click on Control Panel.
Double-click the Add/Remove Hardware icon to start the Add/Remove Hardware Wizard and click Next to continue.
Select the Add/Troubleshoot a device radio button in the Choose a Hardware Task panel, and click Next to continue. Windows 2000 will search for new Plug and Play hardware (New Hardware Detection window).
Select Add a new device in the Choose a Hardware Device window, and click Next to continue.

如果安装完成后，故障现象相同，更换新的芯片。

驱动装上了!
芯片的型号可以识别,但是就是不能烧录程序
JTAG可以confirmed device ,但是点击BLANT CHECK 或者PROGRAM 时就出现\"Unrecognized device or socket empty!\"的错误
我用的是win2000的操作系统,安装了 byteblaster的驱动程序
还有在winxp系统下能否用win2000的驱动?

1、Win2000下的驱动在WinXp下是可以用的，我用过！
2、从你描述的情况看，你似乎应该查一下线路板的连线，比如电源是否供上了，特别是下载线的数据线、时钟线是否与epm7128连接正确？不知你用的是贴片的吗？

我用的是plcc84的封装
epm7128slc84用的的3.3v的电源
jtag编程vcc是用5v和3.3v的电源都试过,而且tms,tdi,tdo,tck都一一查过,连接好了,真是郁闷?
不知道什么原因?

烧录的时候只用了*.pof这个文件烧录,可以直接烧录吗?
还是要一步一步来,先写源代码,在编辑管脚,在编译生成*.pof文件后在烧录???

可以直间烧。我给你一个原理图。

这种问题我也出现过，对于Altera7128在烧录的时候，不能连续一直的烧，因为7128也只能烧100次。否则就会出现你所说的情况。

很可能是你的并口坏了，换一台机器试一下，还有用工控机并口做也会出现这个提示，因为工控机并口和PC机的不一样。

多谢各位大虾的鼎立帮忙
是7128片子的问题,epm7128slc84系列的不支持在线编程
换了一块epm7128aelc84就ok了,很轻松就烧录进去了

7128SLC84-15不支持在线编程？

epm7128slc84系列的不支持在线编程？
这是谁的理论啊？

我的一个同事以前也是用epm7128slc84,用下载电缆连到jtag口怎么也烧不进去
