Yohan the capital I in your pdf in the "Type: xc3sprog –c cm1 –p 0 –I xc6lx150.bit shipping_test.bit " looks like a lowercase L
Figuring this out gets me to a point where the response from xc3sprog is :
Using libftdi,
JEDEC: ff ff 0xff 0xff
unknown JEDEC manufacturer: ff
ISF Bitfile propably not loaded

This response is virtually instant so it's safe to say it's not working. Once again I would like input on what I am doing wrong ?

On another note, I tried running the ebereons dirty version of cgminer with the shipping bitstream, but got a response (something like) cannot mine, all devices disabled. Is this because I have virtualbox open and the device in use there, or am I looking at something different here ?

I know it's hard to read all pages, I'm sure every page in this thread have informations that help to get it running, but to ask 56 pages is not a nice move.

So, first you have to make sure you connect the unit to the VM only when you want to programm the bitstream, if you do not then turn it off! The VM will take the unit automaticaly when you replug the usb cable. That's really bad and i had to fight with it to.

To programm the bitstream in tempoary mode use:
Code:
xc3sprog –c cm1 –p 0 twin_test.bit
This takes a minute or so. Do not turn off the unit! If you do, the programming is lost, it's the temporary mode and saved only to the fpga ram.


To programm the bitstream in to SPI flash use:
Code:
xc3sprog –c cm1 –p 0 –Ixc6lx150.bit twin_test.bit
(there is no Blank betwen "-I" and "xc6lx150.bit"!) The PDF is wrong here.
This takes ~8 minutes! Just wait until you read "Verify: success!" You must turn off the unit to get the bitstream loaded into the fpga. I always turn off and unplug the usb.

Make sure you know what controller firmware you have! SN 62-0001 until 62-0026 have the old firmware and you have to update that first. The old firmware have other dip switch settings and they are not documented. So programming is a pain without to know what switch do what.

I hope it helps a bit to get your first accepted share  Wink
