BeagleBone Black - sorta like an RPi, for the uninitiated
http://beagleboard.org/Products/BeagleBone+Black/

I have one but I've never switched it on

What does BBB stand for?

By crashes do you mean the hashrate falls badly?

I noticed the BBB temperature effected hashrate.  My front fans aren't really directed at the module any more.  I have a piece of cardboard down from the front top edge to the front of the module board and air goes out the sides.  If I remove the cardboard, at least yesterday when I found this and haven't retested it since, if I remove the cardboard the hashrate in the first number crashes very quickly.  I put the cardboard back and it comes up pretty quickly.  I removed the BBB and put stick-on heatsinks on the middle chip as that's where my IR detector says is heating.  I had two 12 v fans I was going to put on a Blade but changed my mind.  I have one of these each on 2 sides of the one module aiming at the vrm's.  I also have a 3" dia 120vac fan, very deep, pointed in from the side passing air over the BBB.  Keeping the BBB cool seems critical.

With all the extra room I have in the Mercury I'm thinking of getting ribbon cables and double pins so as to move the BBB somewhere else in the box where it can be cooled better.

Since you have the big fan cooling the board, try putting cardboard to force the 2 intake fans air down onto the BBB and see if the miner crashes under 0.90 then.

Darn, I was just going to put the cgminer stats line here but when I hit "q" and quit the screen, unlike with minepeon, cgminer quit.  So, I've just restarted it from the command line but it had been cooking along at 134GH/s avg for 5hours 17 minutes.

Just adjusted my cardboard.  Better leave ½ fan clear on each side of the center and the cardboard in that center forcing air down onto the center of the BBB. 

The stats came back up pretty quickly.
KnC 0: | 162.6G/131.5Gh/s | A:39300 R:1695 HW:3638 WU:2150.2/m

Having changed the cardboard slightly, the first figure seems higher which bodes for an overall higher avg if it keeps up.

I looked at your website - the cost of your single blade is a half a bitcoin less than the cost of an Avalon mini...only difference is roughly 5.7-6X the hashing power.

not acting... I'm very familiar with DHL, and from the comments it's hard to tell if the folks with miners sitting in OH called DHL or not, so just trying to help... I want you all to get them ASAP!!!
and promptly point them at the Eligius pool  

What he said applies to me too...Canary is acting like I DIDNT make the phone call.

the ol' 0 submitted on every line scrollling at 1000 lines a second.....lol
slowest saturn that was 255 ish is still holding on at 271

Yes it cleared customs and it will be here Monday or Tuesday, whenever they get around to it.

none between Franklin Park, IL and OH.

Anyone who's package hasn't left OH, needs to call DHL ASAP.  your package has customs/clearance issues.  don't wait, it ain't gonna start moving on it's own, you need to call DHL and see what else they need from you.

How did they change?  Disabling and re-enabling cores?

Didn't know that.  I'm going to let it run 24 hours as it is now then try 0.92 and see if the duplicate share issue is fixed.  So, BertMod works on all versions except 0.96?

Thanks!

I'll speed you up, but I am more of a hack than a polished programmer so rather just give tips to what I did

You can use any of these but will have to change two files:


/www/tmpl/mining_stat.html_tmpl

that one will do the formatting and I make a new one and call it mining_stat.html_tmpl2



the one that does the real work is

/www/pages/cgi-bin/fetch_mining_stat.cgi


when you look inside these two files you will see how to add more fields and just stick with it's naming conventions to pass the values

since I changed the name of the other file, make sure to point to the new named one in this file like:

s!#%#ASIC_STATUS#%#!'"$asic_status"'!g' < /www/tmpl/mining_stat.html_tmpl2


so when you are all set with files in the two directories, you just do a simple
cp fetch_mining_stat.cgi.[newversion] fetch_mining_stat.cgi

then it doesn't disrupt anything since now it just goes to the other formatting file smoothly


ps-save copies in /config since about everything else gets wiped on reboots

back to all 3 sats running 0.96, but they all hang around 275 now still  
same procedure on all 3 saturns...
1. flash 0.90 on the miner, reboot
2. flash enablecores.bin to the miner, POWER CYCLE the miner.
3. putty in and watch cgminer until it crashes, when it does, go to the gui page again, and flash 0.96 back onto the miner, apply, then POWER CYCLE the miner(turn off for 15 seconds via the power supply switch)
thats it.
i had 3 sats going at 255, 265, and 275....  now all at 270 - 275ish

I hope it is best to use the latest firmware version available, as I dont have so much time to test all the firmware versions.

Wish it worked best with the first version, but hey at least I received as promised

I guess you've already tested it, but does it change anything if you put the slot configurarion of the faulty unit exactly like the working one?

Bitfury unit's performance may suffer if hashing boards are in the wrong slots. I'm wondering whether KnC units have similar issues.

is your name Bronan as in = CONAN for Bros?  Its pretty catchy if so.

Is there going to be a updated bertmod ?
The saturn i have running shows a nice 265 Gh on average so i do not want to mess with it too much
However it would be nice to have those extra stats showing some info about the errors and such
I read about bertmod and was mentioned you need the same version as you use on the miner
however mine is 0.96 and could not find a matching bertmod yet.

Phoenix1969, I didn't mention that I generally don't just shut off the power to the miner.  Since I generally have putty open to cgminer, when I go to shut down I hit "q" in putty, quitting the screen of cgminer, then giving the command "halt" and since I'm logged in a root, the system shuts down in a more orderly manner than simply hitting a switch.  I do this because I've noticed with Raspberry Pi if I just kill power the program can get corrupted.  When you quit the screen and command halt, the first thing that's going to happen is putty will send a notice it has lost the connection.  That's when I kill the power.  Might not matter but why take a chance.
