PicoBlaze & jtagloader


segfault

Recommended Posts

Hi all,

 

I have two questions concerning PicoBlaze on Papilio Pro:

 

1. Is it possible to write a PicoBlaze program to Papilio's block RAM using Xilinx's jtagloader utility? Or do I need some special Xilinx hardware? When I run jtagloader, the utility complains about some cable drivers not being present (see the output below).

 

2. The jtagloader talks about some firmware called "xusbdfwu.hex" and it wants to use an "fxload" application. Can somebody please explain to a noob what the jtagloader is trying to do, so that I understand what's going on at all? Thank you :) .

 

Here is some relevant jtagloader output:
