Topic: Noob Issues with FPGA (Read 3287 times)

Update: 

It has been over a month and a half since I initially placed my MMQ order.  Two replacement cards later and multiple peoples' attempts to get it working (including Tom, whose product this is) and it STILL will not work.  I've tried three different power supplies, five different operating systems, three forum members with FPGA and Linux experience have tried SSH'ing in to no avail, Tom himself hasn't been able to get it work ... and at this point, I just want this situation resolved. 



Most recently, Tom SSH'ed in to a clean install and said he had everything set up to work plug and play style for it as soon as my new power supply came in.  Power supply is here, and there is still no progress made in getting it to work.

did you remake and reinstall after the that last configure?

eg the

then the end of the output should be like this

If you run it after root and it doesnt detect still past the the results of the lsusb for the other guys and they might be able to help you .

Okay, I've done that and it looks like that (with ModMiner enabled) for ./configure

you dont have to set a password for root, you can just so sudo su and use your username password and it will enter the root shell

on building bfgminer post the errors, but it looks like you missed ./configure after ./autogen.sh

was it this when running ./autogen.sh



If so install autoconf and the other dependenices
remove the sudo if you have already used the su command.
then

once its compiled with no errors


edit: had wrong libusb package

output should look something like this for ./configure

 Avalon.ASICs.........: Disabled
  BitForce.devices.....: Enabled
  Icarus.FPGAs.........: Enabled
  ModMiner.FPGAs.......: Enabled
  X6500.FPGAs..........: Enabled
  ZTEX.FPGAs...........: Enabled

Still receiving the "Failed to load OpenCL library, no GPUs usable.  All devices disabled, cannot mine!" and nothing registering at any of the /dev/ttyUSB* commands.

You should reconfigure and remake bfgminer without that I'm not sure it has any usb support at all.

I had not installed it this time since Tom insisted I only install what he mentioned in his email.  I've just now installed libusb-dev.  I'll try some steps again.

Looking back through the instructions... did you ever install libusb-dev "apt-get install libusb-dev"?

I believe that is needed.

Ah 

As far as I know the tty's are needed, as that's the method for communication (it is with the icarus boards I have).

I'm happy to try via ssh but I'm not sure you want random forum dudes ssh'ing in to your box 

I had all of these same problems on Ubuntu as well until Tom (who made the mmq) told me to do a fresh install and wasn't able to make any progress when he SSH'ed in.

Did you do "modprobe ftdi_sio"?

I'm not super familiar with linux mint... something like ubuntu might be easier.

I'm happy to troubleshoot with you a bit but forum lag makes it problematic 

results:


Also, it doesn't register anything at /dev/ttyUSB* ... but does show something at /dev/ttyACM0 ... still gives the same error though.

OK, one more time try this:

./bfgminer -S /dev/ttyUSB0 -S /dev/ttyUSB1 -S /dev/ttyUSB2 -S /dev/ttyUSB3

output of that command:

OK, I am more of a cgminer guy but it might just be the options you are feeding it.

Try:

./bfgminer --scan-serial

At this point, I've done the configuration to enable bfgminer's use of modminer .... so now after I cd into the bfgminer folder, I'm typing:


Which gives the error:

What do you mean you "get stuck"? What's the error you're getting?

Here are the instructions Tom gave, which I've followed:


I've done all of that exactly, but I get stuck at the "sudo make install" line toward the end.  I'm running Linux Mint now (Tom said I needed to do a fresh install - I did that) and it doesn't seem to recognize the "sudo make install" command.  Furthermore, ./bfgminer doesn't do anything.  There are no usb devices recognized when I try ls /dev/ttyUSB* but ls /dev/ttyACM0 works.

I have no clue what to try at this point and am still waiting to hear back from Tom.

This is so frustrating.  Also still haven't received the second replacement fpga.

paste your output of
and

Also, when u run the miner, try to run it as sudo, if that works, that means the user ur running under cant see the USB device permission issue easy to solve more info later. if that doesnt work then maybe something else is wrong.. maybe unit is damaged... or bfgminer was compiled wrongly.

Try following this:

I bought them from Tom at btcfpga ... not sure what the correct website is for him because as soon as we placed our orders, he changed servers or something.  Wait, just found the link:

http://modminerquadstore.com/

Oh, and battmann and I bought ours new from that store.

Curious about this as well.

@JonSnow Where did you get your quads? did you get them used?

It sounds like the quadminer may need to be flashed with firmware so that the drivers can be setup; type lsusb on your prompt to see what USB devices you have installed, check with your supplier what is the ID and vendor codes that the quadminer should have. If the supplier states different  vendor ID's and product ID, then it is probably that, but check with vendor first as my experience revolves around ZTEX boards.

Yes, I've followed those instructions all the way through.  When I enter "./bfgminer -o mining.eligius.st:8337 -O 1bitcoinaddress" (with my bitcoin address, of course), bfgminer does start up but it doesn't detect the FPGAs - it only detects the cpu.


I tried the --enable-modminer command, but must not have done so at the right point in the process.  Tom (of btcfpga) has offered to ssh into my system to get them running for me.

Have you followed the https://www.modminerquad.com/index.php?title=Setup_Instructions Linux Setup Instructions?

If so, can you explain how far you got and what was happening?

I know that with cgminer, you need to compile it with --enable-modminer to make it work.

It might be similar with bfgminer.  I understand the two share a lot of code.

I think you also need the ftdi_sio module to be present.  'sudo modprobe ftdi_sio'

Also, unless you have libudev support compiled in, you'll need to specify the device manually '-S /dev/ttyUSB0 -S /dev/ttyUSB1' etc.

I recently received my modminer quad, have set it up, have set up Ubuntu, and have set up BFGMiner 3.0.  BFGMiner seems to run just fine, but it doesn't detect my FPGA cards.  Being new to Linux, I'm not exactly sure how to approach this issue.

Can anyone offer any advice?

The MMQ is connected via USB, but BFGMiner just detects the CPU for mining, not the FPGAs.

Sorry if this is stupid - I've looked and haven't found any help.  It's probably just something simple I'm missing but, like I mentioned, I'm new to Linux / Ubuntu.

Thank you in advance!
