FPGA development board "Lancelot" - accept bitsteam developer's orders.

And please please set the iVendor/iProduct USB descriptors so miners can autodetect it sanely!

I would recommend against that, unless some driver fairy can obtain a WHQL signature for the modified VID/PID. Trying to run with unsigned drivers under 64-bit Windows is an unnecessary hassle.

The market gained would be some open-source extremists. The market lost would be those who can't or wouldn't modify their Windows installations. Let the US-ians fight the monster from Redmond.

He doesn't have to change VID/PID to set iVendor/iProduct.

I don't think you are making yourself clear. Please post the link to the FTDI application notes that describe the change you are requesting.

Sorry, it's iManufacturer not iVendor. Here is a generic USB info on these strings: http://www.beyondlogic.org/usbnutshell/usb5.shtml#DeviceDescriptors

If your FTDI PDF, it's mentioned on page 4 (section 1.1) as "Manufacturer" and "Description" strings.

I have just received my Lancelots! They are just a piece of art. I can assure you that ngzhang just rocks:) Everything was done as promised in time. On top of all I have some extra stuff for free.

Thank you very much ngzhang!
I do not have any hesitation that bitstream will be here soon as promised.
ngzhang is an extremely cool guy, who keeps his word.
ngzhang I am still waiting for your BTC address:)

In case anyone would like to donate a Lancelot for improved BFGMiner support, please PM me.

You got them before you paid for them?

No:)
I wished but....as you know there is no free lunch:)

Here are some results:

Just brilliant:)

Does someone has a howto to make the Lancelot run on Ubuntu 12.04 x64?

Just follow it step by step:) All info applies to Lancelot

thanks for the hint, after compilation of the cgminer i end up with the msg all devices disabled, cannot mine! and when i power on a board i cant see any ttyUSB0 in /dev

In mpblm the boards are recognized it shows me x6500 style serials for each board, but the icarus setup dont work

[loshia]

it works both Icarus and Lancelot believe me. I know from my personal experience.

[Icoin]

ttyUSB0 is not present in /dev on ubuntu 12.04, so it does not work !! If anyone has a workaround for this, since the boards seems to be recognized (when i turn of one lancelot 3 more files appears in /dev but i cant figure which ones that are) and mpblm does see them as x6500 boards there has to be a solution.

it works both Icarus and Lancelot believe me. I know from my personal experience.

I can imagine you made a good expirience, but im quite sure your not using ubuntu 12.04 x64

I tried to compile  ftdi_sio (even when they say there that since ubuntu 11.10 it is included in the kernel) but this ends up in telling me that modversions.h cant be found

[loshia]

Dude,
First use apt-get install. When i was young i was trying to compile everything by myself. I realasied that i can not maintain whole linux distro
I am joking.

Did you read cgminer/Readme
did you apt-get install
libudev headers
        (This is only required for FPGA auto-detection and is linux only)

        libusb headers
        (This is only required for ZTEX support)


Just goolgle about apt-get install ftdi_sio i guess you miss libusb-dev (if there is such thing) or something else which for sure can be installed with apt-get

Good luck
It shall be somewhere inside:)

i see, but have a look here:

http://pastebin.com/LWyV74T0

there you can allso see from lsusb that:
devices 5 and 6 are x6500
devices 36, 37, 25, 26 are Lancelot

Maybe you see something i dont.

I googeled for apt-get install ftdi_sio by now i have not found anything usable. But thanks for the help

[kano]

ftdi_sio should already be there in the kernel ...

From looking at your pastebin (which gives exactly what I was hoping from dmesg when I spoke to you in IRC ... ) Try:

sudo modprobe ftdi_sio vendor=0x0403 product=0x6001

See if that works.

[flynn]

I just ordered my dev kit
I can't wait to play with it

[Icoin]

sudo modprobe ftdi_sio vendor=0x0403 product=0x6001

gets me:
FATAL: Module ftdi_so not found.

[kano]

sudo modprobe ftdi_sio vendor=0x0403 product=0x6001

gets me:
FATAL: Module ftdi_so not found.

Coz there's supposed to be an i in there?

If not then you have screwed up your 12.04 somehow.
Wipe it and start again.

It is part of the standard kernel
