Connect USB Blaster to Altera Live Design Evaluation Board ( LPT )

Hi,

Today I got my Terasic USB Blaster cable and I got it working with the LiveDesign board.

first, in the USB blaster cable I removed the 10 pin ribbon connector and replaced it with individual flying leads, this is only to make it easier to connect each pin to the board.

Then I connect:

USB Blaster (10 pin) -> LiveDesign (J1C 26pin)

1 TCK ------------------> 2

2 GND ------------------> 25 (you can use any pin from 25 to 18)

3 TDO ------------------> 11

4 VCC ------------------> 3.3V located at JP2

5 TMS ------------------> 3

9 TDI ------------------> 8

Note that pin 4 (VCC) is connected to a different header because the J1C connector doesn't provide 3.3v.

Now, this works perfectly with Quartus II ver. 9.1. I use windows 7 64 bits.

However when using latest Quartus ver 11 then sometimes it detects the cable, sometimes it doesn't. I can't understand why. But 9.1 works flawlessly. I already tested several projects and they all load ok.

I use LiveDesign board with Cyclone I FPGA.

For the drivers, I just use the ones that come with Quartus under ...\Altera\11.0\quartus\drivers\usb-blaster

Good luck to all
