Does DS-5 AE support using the USB Blaster (Rev C) cable as the connection ?

The documentation for DS-5 says that it supports the USB Blaster II. This works connecting to the USB Blaster II on the eval board. 

 

When I try to connect with a USB Blaster download cable, the debugging doesn't want to load the .axf file. It sees the HPS core on the JTAG chain, but the load always fails. 

 

Should this work ? Or is there a difference between the USB Blaster download cable and the USB Blaster II that is required for DS-5 debugging ?

I think this should be working, you sure you have installed the driver correctly?

I think so. 

 

I can use the blaster II which is built into the dev board fine. 

I can see the items in the jtag chain with jtagconfig fine. 

I can select the usb blaster cable from within ds-5 fine. 

I can do some operations from within ds-5 such as writing a few dwords to OCRAM with the usb blaster cable. 

I've tried two usb blaster cables. 

I've tried a couple of different USB ports on my PC. 

I've tried to have just the HPS on the chain and the HPS & FPGA on the chain. 

 

I had the altera reps in this week and they thought it should work too. 

It seems like its probably signal integrity sort of issue, but the USB Blaster cable is the slowest rate and in theory, if I had a USB Blaster II cable, it would have faster options available, so I would assume that could be worse. 

 

I guess at this point, I'll get a USB Blaster II Cable and then debug my board when its available. I'm not sure I want to invest a lot of time debugging an eval board for signal issues.

Okay,, are you using both altera build dev kit and altera usb blaster?

Yes. The eval board is Altera's Cyclone V board (100-0321003-CI REV C) and the USB Blasters are Altera REV C units (the ribbon says P06-18025R-00 RoHS, but I think that is likely the ribbon part number).
