OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

[BitMinerN8]

While I see r-pi listed in the subject, I see no instructions or downloads provided. Am I missing something?

I think it was more of a statement, "cgminer works on a Pi" like "cgminer works on Windows". I personally have many BFLs on several Pi, for which it works rather well.  Actually mining with it, not so much.

i got my 2nd pi in the mailbox last week. at the moment i got some problems with wireless under raspbian. want to drive my ztex single and ztex quad with it anytime soon... :-D

stock 700mhz ARM gets right around 118Kh/s.

You  do not mine with the hardware itself... you use it to attach FPGAs to mine with.

After upgrading some of my rigs most of them fail with this segmentation fault:

Weird, I've been getting HW errors after upgrading to 2.7.6 also. I thought my GPU was on the way out because I've never gotten any before.

[ocminer]

I've had few H/W error before also, but cgminer 2.7.6 seems to "freak out" and crashes randomly when a h/w error occurs.

thats not the case with good old 2.4.2, it just counts up the errors

As per the README FAQ ...
Add "-T -D --verbose"
and post a log

However, it's better with a core dump to show exactly where the problem is.
Before you run cgminer:
ulimit -c 2097152

However that won't give much details about where it crashed without:

If you compile it your self, then (as I said 2 pages back):
CFLAGS="-g -W -Wall" ./autogen.sh --enable-icarus --enable-bitforce --enable-ztex --enable-modminer --enable-scrypt
make clean
make

And of course you don't have to include all the options on the end you don't need ...

Once it crashes you'll have a core.nnnn in the directory
where nnnn is the process number.
Find it with
ls -ort core*

Then:
gdb cgminer core.nnnn
bt

and bt will tell you where it crashed ... to add to the pastebin


Edit: however, with that many errors, it's likely to just be in the ATI driver and you probably need to clock it down more?
Nope - it doesn't look like it's lots of error in the HW: counter ... anyway as above ...

[kano]

Thanks kano, --no-restart worked, you are right, the fan reading on gpu 3 fails, even though
all three cards are 5970s, so there is actually just 1 fan on each card..

Strange that it works with card 0 and card 2, but not card 1 ?!

Maybe a BIOS error of the card ??

I actually only have the problem on this particular rig..

here a screenshot:
http://imageshack.us/a/img685/3752/bildschirmfoto20120927u.png

My only guess now, as I mentioned before, you may need --gpu-map
It looks like it not associating the fan with both GPUs ... but I don't have any dual GPU cards so I've no idea other than read the README

did that now, exactly same crash, this is my "debugging info":

Yep - thanks. The line doesn't explain the problem - but it shows it's at least in findnonce when it crashes for you - so probably a bug I introduced.

I've also thought of a easy (should have thought of before ) way to try reproduce it myself.
Add 1 to each nonce value returned should give me LOTS of HW errors to hopefully get the same result.

I'll try sort that out later today - thanks for the info.
If I can't get it to happen I'll ask for more help to run a debug version I'll put up for you.
But I'll let you know first.

While I see r-pi listed in the subject, I see no instructions or downloads provided. Am I missing something?

For Raspbian, my steps went something like this:
<... snip ...>

Thank you VERY much for this guide.  I did encounter a problem with this step:

root@raspberrypi:/usr/src/cgminer# bash ./autogen.sh --enable-scrypt --enable-bitforce --enable-icarus  --enable-modminer --enable-ztex --with-libudev
Running autoreconf -if...
Configuring...
configure: WARNING: you should use --build, --host, --target
configure: WARNING: invalid host type:  --enable-modminer
checking build system type... Invalid configuration ` --enable-modminer': machine ` --enable' not recognized
configure: error: /bin/bash ./config.sub  --enable-modminer failed
root@raspberrypi:/usr/src/cgminer#

Then I remembered I did not need modminer (no HW for me - YET) so I trimmed it down to the command that I needed:

root@raspberrypi:/usr/src/cgminer# bash ./autogen.sh --enable-bitforce --with-libudev
 

... and it worked.  But then "make all" also failed:

root@raspberrypi:/usr/src/cgminer# make all
make: *** No rule to make target `all'.  Stop.

root@raspberrypi:/usr/src/cgminer# make
make: *** No targets specified and no makefile found.  Stop.

root@raspberrypi:/usr/src/cgminer# ls -l M*
-rw-r--r-- 1 root root  2470 Sep 27 20:31 Makefile.am
-rw-r--r-- 1 root root 91117 Sep 27 20:47 Makefile.in

Now I'm stuck.  Damnit - I hate being a n00b at new stuff!     (Although I used linux in a previous life a little bit, I'm mostly a Windblows guy.    )

[ChipGeek]

Ah crap.  I scrolled up and I see the problem:

checking for working alloca.h... yes
checking for alloca... yes
checking for OpenCL... no
checking for pthread_create in -lpthread... yes
checking for json_loads in -ljansson... no
checking for library containing addstr... -lncurses
checking for yasm... /usr/bin/yasm
checking if yasm version is greater than 1.0.1... yes
checking libudev.h usability... no
checking libudev.h presence... no
checking for libudev.h... no
configure: error: libudev not found
root@raspberrypi:/usr/src/cgminer#

Fixing now...

Edit: Or I'm trying to fix it but I'm clueless (apparently).  I tried:

apt-get install libudev

with no luck.  If someone can help me with this I would appreciate it.

[kano]

Never built on that - but the ./autogen.sh should work that way fine with 2.7.6
I guess there's more to getting it working - you'll need to ask P_Shep I guess?
He seems to get it working on the usual hardware

When compiling you need the development package of the library when it is not found so to find it install apt-file.

Code:

apt-file search libudev.h
libudev-dev: /usr/include/libudev.h

Code:

apt-file search libudev.h
libudev-dev: /usr/include/libudev.h

Thanks but that did not work for me:

Code:

root@raspberrypi:/usr/src/cgminer# apt-file search libudev.h
bash: apt-file: command not found

- The linux n00b

Edit: I hope this is not too off-topic but I believe it will be useful for other (n00b) users to get cgminer working on their Raspberry Pi.  Or at least those that want to compile from source.  Now that I think about it, didn't someone offer pre-compiled binaries for the RPi?  Or was that for one of the Bitcoin clients???

can't you just do:

Code:

apt-get install libudev-dev

Hope you'll find it, let me know if I can help you any further

Is there a way to make mining on a PC that has a AMD 7950 and Intel HD Graphics possible?

My Motherboard is a Z68, I would like to connect 1 or 2 Computer Displays to the HDMI and DVI on Z68 motherboard and 1 or 2 displays to my AMD 7950.

When I start Cgminer it says too many gpus or something along those lines.

Yes there is, but you will need to use a combination of parameters to these options: -d, --remove-disabled, --gpu-platform and --gpu-map. Start with 'cgminer -n' to read  what cgminer finds and then read the advanced section on gpu-map in the readme.

So this allows me to use the 7950 to mining when it's not doing much in windows 7?
I can have 2 displays connected to 7950 and 2 displays connected to Z68 HD3000 and just before I start gaming I just disable 7950 in cgminer?

Obviously primary display in windows 7 needs to be connected to 7950 so that games start on 7950.

Ok if you need the HD7950 for gaming you can't mine on it at the same time without a noticeable lag.  Disable lucid MVP and connect a cable to your mobo and then use just HD3000 for gaming. Mine on the 7950.

Thanks for suggestion but I do not want to game on HD3000, I want to mine on the 7950 only when I'm not gaming (I'm not gaming 90% of the time.)

If you set the 7950 to dynamic intensity mode, you will be able to game without a problem without needing to disable it.

Thanks to dlasher, SAC, burger, and especially ckolivas and kano; my BFL single is now running on my R-Pi!  Soon I will re-post dlasher's guide with the corrections I used to make it work for me.  (First I will test with a fresh Raspbian install.)
