Hi !
I'm from Poland and I have problem with connect USB Blaster to Evaluation Board. I have Altera Live Design Evaluation Board with ByteBlaster ( Port LPT ). I buy USB Blaster and I don't know where connect it. I use Quatrus II 10.1 and USB Blaster is connect to HARD_TDI,TMS,TCK,TDO , when I try start programmer get this error : ""unable to scan device chain. cann't scan jtag chain" All connection is corectly. Maybe I should disconnect a buffer (u1c) ?? I apologize for my poor english :(Link Copied

Googling for "Altera Live Design Evaluation Board" shows an Altium kit.
Could you post the schematic. From the ones I found, it looks like they only have a parallel port connector, rather than the recommended 10-pin header. You can make an adapter to take the TCK/TMS/TDI/TDO signals between a 10-pin socket and a DB25. You'll also need a ground, and a power signal for the buffer inside the USB-Blaster. You'll want to connect to the PP_HARD_Txx signals. For the power, use one of the other data signals that are pulled up to VCC. The USB-Blaster buffers won't draw much power. Send a complaint to Altium. Perhaps they have an adapter cable. Cheers, Dave- Mark as New

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 e.- Mark as New

I've noticed it act a little flakey, but I have not bothered to track it down either. Cheers, Dave

USB Blaster is not listed in the HW settings, that's the problem I was talking about.
I did the test with a Max II evaluation board. Tonight I'm working with the Cyclone II LiveDesign board and Quatus 11 works ok (?????). But 9.1 works ok always.- Mark as New

I'm not sure what the issue is, but at least if we make a note of what happens, others can comment on whether they see the same issue. Cheers, Dave
