About Nios II Eval Kit of Altera

Altera_Forum · ‎04-26-2005

I bought Altera Nios 2 Evaluation Kit, but it does not communicate to PC thru USB-cable. Every time I connect it to PC, it said that USB driver needs to be installed and then I did that. Unfortunately, I could not install the USB-Blaster driver provided by Altera. Who recommend me how to handle it?

[EDIT:] Just realized that you are having trouble installing the windows driver. This may sound silly, but try installing it on a differnt USB port. Other than that, I wouldnt see why the driver that came with it wouldnt work. I did not have problems with the windows driver portion.

[End Edit]

Do you have more than one JTag device installed? Such as a byte blaster? or anything else? If so, it may be confused, and you will have to specifey with the --cable option which JTag device to use.

However; if you only have one make sure you use the (in the SOPC Builder 4.20 "Nios SDK shell") jtagconfig command to either install or remove jtag devices.

After all this is finished, it should work.

type

nios2-terminal (if you have more than one device then --cable X, were X represents the number of the device to use)

Should work.

Type "jtagconfig" from an SDK shell prompt and pay attention to the output. If you get nothing (or an error), you've got a Windows driver issue. If, however, you get some sensible, like:

$ jtagconfig
1) USB-Blaster 
  020030DD   EP1S25/_HARDCOPY_FPGA_PROTOTYPE

then look to see if there's more than one device connected.
