Can I get information on how I would connect the JTAG to the programmer to program Altera EPM 3064 CPLD I have?
Thans! |

Can I request that the next version of the software really optimize the JTAG? I'm getting about 21 seconds with program and verification. Very cool that it works now. Thanks! |

No. The file loaded into the buffer will be processed when doing programming. All comments will be removed and not going to the device memory. If the comments go to the device, then the device will never work.
You can use a standard Altera JTAG blaster to do the verification.

The JBC file verified correctly but i'm afraid how the program loads the JBC file into the software. If there are comments and headers in the file, i'm afraid it takes up some of the code space which is incorrect. I can send a screenshot of the file loaded and you can tell if me it looks funny to you or not. |

Currently only .jbc file supported. If the chip can be verified after program, then it should work. Otherwise check your code.
There are rooms in software to make it faster. But the USB Blaster hardware is specifically tailored to JTAG only, it should work faster. |

Can the programming be changed to load POF files? Loading JBC file works but programming the chip does not result in a working CPLD. Loading the JAM file will just give a bunch of ASCII text that has nothing to do with the program.
Also, the programming speed of an altera usb blaster is 2 seconds but the GQ-4X is 17 seconds. Is there a way to make it faster?
Thanks! |

The JTAG only supported on GQ-4X for now. It should connect with the JTAG adapter. See:
http://www.mcumall.com/comersus/store/comersus_viewItem.asp?idProduct=4310
On JTAG adapter, there is a standard Altera JTAG port on it. The port pinout is on the adapter.
If you do not have this JTAG driver adapter. Then you can try following connection. But better not let wire be longer than 20cm(8 inches)
If you do not use the JTAG adapter, then it may not work stable. |
