[BOUNTY 5 BTC] Clear instructions for cgminer's --scan-serial option

[lodcrappo]

Thanks for the help. I have determined that BAMT does not contain the proper serial support needed to create the ttyUSB* files. Moving on to ubuntu this evening....

I am interested to know how this was "determined" ?

By my non existent linux skills..... hence the bounty for some help.

Hey gigavps I saw in the cgminer thread you got this mostly working??  Would you mind sharing what was needed for BAMT + cgminer + BFL? (given there was bounty, no would be a perfectly reasonable answer here)

Hi gnar1ta$,

The bounty has gone to lodcrappo (the creator of BAMT) as he was able to log into my rig and figure out what was needed to get the debian OS to recognize the single. There kernel mod was there but not enabled and there were a couple other things he did to get it working.

Lodcrappo created fix #7 for BAMT 0.5 to distribute this to the masses.

I now have the single plugged into a BAMT rig and cgminer recognizes it and runs it. Unfortunately, the gpumon and mgpumon tools are based on gpus and not devices and the cgminer api call "devs" does not return the BFL device, so no monitoring.

We are close.... I can smell it.

We are close.... I can smell it. 

That's good to know.  I spent some time without BAMT on my rigs...never again.

I know the feeling. Compiling shit and trying to find everything to get ubuntu setup with cgminer is quite a chore. BAMT is my friend.

I have not written API support yet - no bounty oh well I'll consider it some time in the future

Luke-jr wrote the BFL support but didn't bother adding the API code (even after I pointed that out to him)

(The first post says "LINUX" not BAMT - thus my last post was actually correct )

Well I don't have one yet, but I'll contribute 5 BTC to you to write in the support.

Just got 3 BFL Singles working.

I'm on ubuntu.

--scan-serial auto only detected the first device.

So for the cgminer command line you should expect somthing like this:

Code:

CGMCMD="./cgminer \
    -o $MINERPOOL1:$MINERPORT1 -u $MINERUSER1 -p $MINERPASS1 \
    -o $MINERPOOL2:$MINERPORT2 -u $MINERUSER2 -p $MINERPASS2 \
    -o $MINERPOOL3:$MINERPORT3 -u $MINERUSER3 -p $MINERPASS3 \
    --scan-serial /dev/ttyUSB0 \
    --scan-serial /dev/ttyUSB1 \
    --scan-serial /dev/ttyUSB2 \
    --failover-only \
    --disable-gpu \
    --submit-stale \
    "
echo $CGMCMD
cd $HOME/bfl

exec gnome-terminal --command="$CGMCMD" --title="BFL" --geometry=104x44-0+0 &

Disclaimer:  This may have been fixed recently, but I don't think anyone has been working on this.  Luke-Jr may have, I'll check out the most recent source later. But I KNOW this works.

Happy hashing.

Yep there are issues with --scan-serial
If you have both Icarus and Bitforce enabled and plug in an Icarus, the "auto" will hang.
Luke-jr posted a hack pull (well I consider it a hack) to work around that.
But it needs some work still as I have mentioned in 2 other threads.
Clearly specifying --scan-serial each device is the most reliable method at the moment.

I have determined that BAMT does not contain the proper serial support needed to create the ttyUSB* files.

Just want to note the solution to that issue here (this has been posted by somebody elsewhere too), since I searched for it a while ago and it's somewhat frustrating to find this thread without the obvious solution for the generic Linux user without automatic ttyUSB mapping:

Depending on yourLinux distro your BFL might not show as a ttyUSB* device.

If you do a

Code:

ls /dev/ttyUSB*

and nothing shows up then

Code:

sudo modprobe ftdi_sio vendor=0x0403 product=0x6014
sudo chmod a+rw /dev/ttyUSB*

This reqires that you have general USB device support installed.

I got the vendor/product pair from dmesg (after plugging in the Single)

Code:

dmesg | grep -i bitforce

to find the USB device number

Code:

dmesg | grep -i vendor

to find the vendor/product codes (use the one with the matching USB device number)

compile cgminer with

Code:

./configure --enable-bitforce

and then

Code:

cgminer -S auto

and all the usual other parameters, should find your BFL Single.

It took me about 4 hours last night to figure this out.

I wish you would have posted this 24 hours ago.

Dang, if I only knew that sooner!
Then I hope it will be helpful to someone else

I am having a new problem.  I just switched to a thin client that only uses 36 watts.  I have 2 other thin clients running with Ubuntu 11.04 on them.  Only on this one cgminer looks different.  It is just one line and everything is flying by and it is hard to see what is going on.

Is this a different view?  Did I set it somehow in the conf file maybe?

How do i get the normal cgminer status window where I can see all my miners in a row?

Thanks
