My board is a Version 2.3.  If you have a version 1 M board DO NOT GET THE SAME CHAINMINER BUILD AS ME.


oh and as far as my results I left the resistor the same.   the new chain miner build definately improved results.

What I also noticed is there is a even newer upload on buzzdave's links.  Is it a newer build or older build??

I have the same board version, could you post how you updated chainminer?  git pull and git clone both didn't work for me.

ChainMiner for M Board Version 2.X boards
DO not use this guide for Version 1x m-boards.
It will fry your chips.  This is only meant for Version 2 of the M-board.

I apologize for grammar as I took 2 sleeping pills and I can barely feel my fingers.

1.login as pi or root

2.  type "nano /run/shm/.stat.log"   if you wish to see the performance of all the chips on your board before upgrading chain miner.
(optional step)
3.(backup your chainminer version)  (this creates a copy of the folder)
a. sudo cp -a /opt/bitfury /usr/bitfury.backup
b. cd /opt/bitfury/
c. pwd  (make sure you are in /opt/bitfury)
d. ls -al (or type dir)
e. rm -rf chainminer  (this removes everything in the chainminer folder and the chainminer folder itself)
4.  make sure you are in the /opt/bitfury directory and not in /opt/bitfury/chainminer (it should be deleted anyway
5.  type "git clone https://github.com/bfsb/chainminer.git"
6.  it should now start getting the chainminer git.
7.  now type "cd chainminer"  you should now be in the chainminer directory
8.  type "make"
9.  Its going to take 5-10 minutes to create the chainminer...maybe longer.
 I got some warning but everything was fine after it all finished.
 it will go back to a  bash prompt when done.
9a.  Just wait...this is the longest part of doing this change..
10.  sudo reboot

plz make "how to" step4step frob back up to chainminer upgrade manual for noobs like me)

ChainMiner for M Board Version 2.X boards
DO not use this guide for Version 1x m-boards.
It will fry your chips.  This is only meant for Version 2 of the M-board.

....

That's how I did it yesterday ... worked like a charm ... if you do it the first time ... the make command might take some minutes be sure to let it run till it gets you back to the command line ...

...
8. How to update on the most actual chainminer version (gitpull)?

... first .. if it ain't broke don't fix it ...

do backup of your actual bitfury chainminer version...

Code:
pi@bitfury ~ $ cp -a /opt/bitfury /usr/bitfury.backup
Then move to chainminer get latest version clean make ... restart ...

Code:
pi@bitfury ~ $ cd /opt/bitfury/chainminer
pi@bitfury ~ $ git pull
pi@bitfury ~ $ make clean
pi@bitfury ~ $ make

restart the miner ... and hope it will still hash ... :-)

Is everybody compiling stuff on the pi, or has anybody had any success cross-compiling from a more powerful machine?

I didnt get bitminter pool working with my bitfury, can someone help me??

what url must i insert in the web interface? "stratum+tcp://mint.bitminter.com" or "stratum.mint.bitminter.com" or something else?? the miner not start with these?!
mint.bitminter.com port 3333

I apologize for grammar as I took 2 sleeping pills and I can barely feel my fingers.

1.login as pi or root

2.  type "nano /run/shm/.stat.log"   if you wish to see the performance of all the chips on your board before upgrading chain miner.
(optional step)
3.(backup your chainminer version)  (this creates a copy of the folder)
a. sudo cp -a /opt/bitfury /usr/bitfury.backup
b. cd /opt/bitfury/
c. pwd  (make sure you are in /opt/bitfury)
d. ls -al (or type dir)
e. rm -rf chainminer  (this removes everything in the chainminer folder)
4.  make sure you are in the /opt/bitfury directory and not in /opt/bitfury/chainminer (it should be deleted anyway
5.  type "git clone https://github.com/bfsb/chainminer.git"
6.  it should now start getting the chainminer git.
7.  now type "cd chainminer"  you should now be in the chainminer directory
8.  type "make"
9.  Its going to take 5-10 minutes to create the chainminer...maybe longer.
 I got some warning but everything was fine after it all finished.
 it will go back to a  bash prompt when done.
9a.  Just wait...this is the longest part of doing this change..
10.  sudo reboot


very nice! thank you very much! )

Why would anyone want to bother to build a cross-compilation environment?   That would require a great deal of effort to duplicate something that is already trivial to perform on the RPI...

To make repeated testing of new versions faster. Or to make the compile time on git-bisect bearable for finding bugs. I already have a cross-compiling environment for ARM, to compile cgminer for my other raspberry. Only reason I haven't added chainminer to it is because there's so far been only one update.

Exactly, and some things are so slow to compile on a pi that it's just unbearable.

-Redacted-, I haven't tried compiling chainminer on a pi yet, so I'm afraid that I'm rather ignorant of the reality. However, I got the sense from darkfriend77's post that it takes a while, which is when I think it starts to become worth thinking about putting the effort in to cross compile.

I think step #9 on the front page should be revised as it is not rookie friendly.  Following those steps will result in errors on a Verision 2.X  September 16th kit as it will not reach a git repository without the steps I laid out.

just ran the above chainminer gitpull, up and hashing again now, at auto 54 and decent rates (still climbing)

Previously, i had about 34ghash average poolside using 2 workers at difficulty 16, autotuning, and pencil mod of 1.178k. The actual hardware hashrate was closer to 37.5 but 2-15% error rates on the chips. aftermarket cooling includes a fan on each face of the board, as well as multiple heatsinks (tiny one on each chip, and then 5 small heatsinks on the backside, 1 opposite each capacitor cluster)

EDIT #1 (5min): 1 worker, diff=16 (bitminter), autotuning is 54 across the board, hashrate: 35.86Ghash, noncerate: 35.03Ghash.  This is looking really good with the chainminer update!
EDIT #2 (15min): hashrate: 36.5Gh, Noncerate: 35.0Gh,   autotuning is moving most chips up to 55 now
EDIT #3 (30min): hashrate: 37.4Gh, Noncerate: 36.3Gh,   autotuning is about 50/50 between 54 and 55 on all chips. Several chips running at 54 have no errors, and a chip at 55 is 7% errors (hopefully fixed by next autotune)

24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461 also selling 6" M-F-M PCIe splitters and PCIe-PCIe
No longer a wannabe - now an ASIC owner!

Just took a look at the results from 12+ hours of logging yesterday after pulling chainminer v1.2. The board looks quite stable and error rates dropped significantly (~1% over the entire peroid). I'm looking at 36 GH/s sustained over long periods just dc fans and no heat sinks. I've manually clocked all chips at 54 and have not noted any benefit in using the auto feature in v1.2. Now someone push the board up to 40 Wink
