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.

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.

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.

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 ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

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 2097152However 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 makeAnd of course you don't have to include all the options on the end you don't need ... ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) 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 btand 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 ...

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.pngMy 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 ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

I've also thought of a easy (should have thought of before ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif) ) 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! ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) (Although I used linux in a previous life a little bit, I'm mostly a Windblows guy. ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) )

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.

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 ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

Thanks but that did not work for me: 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???

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.
