Subject: Re: FPGA reprogramming on ZedBoard / Parallella board


I've just tried loading ZedBoard's official bitstream and then the
original Parallella bitstream a couple of times on the booted up Linux
system - everything worked fine.  Then I tried loading your bitstream
again, and got the same problem again (no Ethernet, although the LEDs
behave like with the original Parallella bitstream).  Power-cycled.

Then I tried loading your wrong-size parallella16_prototype.bin (for the
first time).  I did not expect this to result in anything good, and it
did not: not only did I lose connectivity to the board, but also the
LEDs stopped doing their counter pattern.  Power-cycled again.

I think it's mostly ISE version difference.  I think a slightly older
version (14.4?) was used to generate Parallella's bitstream.
