Any other tips I can try?
Regards.
Are you sure that there are no power issues? Maybe you can try a different PSU or a different plug (i.e. the molex connector), or another USB cable, or maybe as the final test un-plug the fan and try if it works.
Hiya, I forgot to tell everyone what my power config is
I have separate power adapters for each unit, So a quick swop around eliminated this problem, All my adapters work fine in the working lancelot's.Did not know about the fan? I tried this and it did not work anyway, But worth a try.

If i place a order on the website today how long will it take before it ships?

By the way:
I wish to say "thank you Blackarrow" because -instead of the ATX PSU board I've ordered- I received three PSU with three "splitters" with 4 Icarus plugs each. It's clear that they haven't the board or the needed cables, and they delivered anyway, even if the PSU are more expensive!
Thanks.
Then another (really!) good news are:
- my "kill-a-watt clone" is measuring 23 watts off the wall (way lower than 30!)
- my icarus (other nine are still waiting in their box) is hashing at about 5.80 units/m (diff 1) on 50btc - I'm reading a value >390Mh/s
- the small fans are really silent and the back of the FPGAs are quite cool after 2 hours of hashing, no liquid cooling needed

I am not a CGminer user, But I just downloaded it to try it out, And that does not detect the FPGA either. I have checked it detects the other three and it does, As far as I can tell, Its something with the boards, I have checked everything else against all other components.
Is there a reset? What is used to flash these things? Is there something I can download to see if it can find the device?

You should see them in device manager as FTDI USB to Serial Port (com xx). It might be a good idea to wait the next version of cgminer which shouldn't require you to add any parameters.
Do you have any leds blinking when you plug it in and turn them on? If not, check the fuse (big white cube on the back of the board), it might have burned out due to a short circuit.
To re-flash them you need a JTAG cable. We have tested every one of them and we only shipped working devices.
However, if you are sure that they're defective send them back and we'll replace them for you.
Regards!
I some how have got the boards to be recognized by windows, Bare in mind the other three worked in 5 min, I have one on com 5, I scan com 5 and it says "probe of port com 5 failed: timeout" I have no idea what it means.
All the lights flash when I scan the port, So It knows it's there, All the drivers are in and detected by device manager (using drivers CDM v2.08.28 Certified), I have tried separately away from using the hub, I'm closer but still cant get system to access the devices.
Any other tips I can try?
Regards.

Hi, blackarrow .. what JTAG cable I have to use? Is xilinx usb platform cable needed? I or II? Or anything else? And second question: can I find anywhere on internet your default lancelot bitstream? or is it ngzhang's icarus bitstream, published on git?
Thanx for answer.

Hey Guys,
I made up a custom PHP script for tracking my FPGAs mining stats (including stuff like % of the investment returned by mining and time needed to reach a certain amount etc)

Dont know if this is on topic, I have 5xlancelots, But 2 of them are not recognized by the computer?
I was having a bit of a similar problem. On the command line, when I started cgminer, I was using -S com9 -S com10 and so on. The one on com9 would work but the other com ports above that wouldn't. Then I read the README file said to do it like this under Windows: -S \\.\COMnnI am not a CGminer user, But I just downloaded it to try it out, And that does not detect the FPGA either.

A bad HUB / Cables could be an explanation. Check this. Sometimes it could be feedback power over the USB cables as well. On my Ztex boards i have something similar to a clear CMOS Jumper to reset the boards configuration.
Did you try to connect them solo each board, or all together?
Try to conect solo each board, so you can determine, the two are OK or not.
Basically I have spent a few hours swopping and changing cables, I have rotated the boards starting them independently and together, Its the same two boards I cant get to recognize.
I have also used another computer, the first three are all good, The other two, Nothing. not even a sound/bubble to say I have plugged something in.

to cover the basics, I am using xp with bitminter client (yes I am a noob) I have swopped around all cables power adapters, Its the same two boards not being picked up, When I scan for all FPGA's on com ports the 2 in question have a different light cycle to the others, The 3 detected quickly show a orange and blue light together, The other two don't. (but all flash together at first)
I have no idea what the 6 push buttons do (have not pushed them) 4 on one side 2 on other.
Any suggestions?

When all boards are OK, there can be problem with COM ports in windows. Do you have enough free COM ports?
You don't have to set anything special on the board. Just power on and run the miner on PC. Switches, buttons etc. are there, because it's a development board.

The default Windows cgminer builds appear to require OpenCL.dll installed on the system.
There is a cgminer-nogpu.exe in the windows binary zip file

I received my 4 units a few days ago. Thank you.
I had trouble getting it to work with cgminer right away. So I was using BitMinter for a few days at first.
The default Windows cgminer builds appear to require OpenCL.dll installed on the system. I built from source without that dependency, but still couldn't get it to work. It appears that for com ports above 9, you have to list them in the arguments as -S \\.\comXX. instead of -S comXX. This was in the README. I should have read it more closely at the beginning. It's working fine now on my Windows desktop.
Cgminer is much less resource intensive than BitMinter, which ran under Java. I also have an Asus RT-N16 router with TomatoUSB firmware on it with Optware installed. I've read about people running cgminer under OpenWrt. Anyone know how to get cgminer running under Tomato?

If you need more info about FPGA it's also in FPGA-README
Also as I've implied in this thread, the next version of cgminer will have a pure USB Icarus driver (which handles the Lancelot also) which will require the driver changes as mention in FPGA-README when it's ready.
May 21, 2013, 05:56:03 AM
Thanks I thought the syntax was a comma for things like that. I did not see any examples with -S repeated. I should have looked harder. They work.
