Code:
xc3sprog c cm1 p 0 Ixc6lx150.bit twin_test.bit
does not work, but this time it's complaning about a filename issue to me. My initial hunch is that since the board im punishing is #108 the firmware filename on it has changed along the way. I'll re-read up on this , of how I wsh the search function on this forum worked better 
.. but for now Im going with the temporary flash.Strange...
When you type a "ls -l" do you see the files in the directory? And make sure you use the correct filename, the filename in UPPERCASE is XC6LX150.bit, I did a typo the first times, so I used xc61 (number one here! but it is a small "L")...
Here is my directory (ls -l) after copy the files from usb stick:
If you have the same, the commandline should work.
good luck!
Recieved clarification on this, thank you Slipbye ...flashing in progress now
I decided to get back to permanently flashing my boards, my problem appears to be that the file xc6lx150.bit is not there, am I correct in assuming that copying it in there with the usb stick will result in success ?
...and does this mean that the virtual machine requires the bitstream that will be removed as a "reference point" so it can permanentley flash in a new one ?
