Linux mining distro for the Raspberry PI - MinePeon

[Bonz]

have you tried wiring better power to the jaycar?

yeh, i got 2 of those 10 port ones with another 3 on the slow boat from china running on an atx psu. Hoping they arrive soon so I can finally get it sorted. There is very few options locally which is why I ended up with the one from jaycar.

i recommend grabbing some of the cheep ones from e-bay  like this one

http://www.ebay.ca/itm/10-Ports-Splitter-USB-HUB-2-0-High-Speed-AC-Power-Adapter-for-Laptop-PC-Blue-/330907999621?pt=US_USB_Cables_Hubs_Adapters&hash=item4d0ba75d85

I use one of those and I'm waiting for 2 more. I use it with a multivolt power unit that gives me 7,5Amperes @ 5volts.

and the cutting the power cord and wiring 4 of them to one of these

it works great on my pi

I need to have one of those.

it works fantastic I run everything off of it my 4 hubs 3 fans and the PI i have 35 miners (1 open slot) =D

I need to have one of those.

yes, I shortened the lead to about 4 inches and soldered it to its own 5V rail on my PSU
(when i first got it I was gonna solder straight to the pcb, like I did with the ebay hubs, but didn't look to be easy so i closed it up again)

It was doing 7 usb's and now 3 so am sure it is screwed.. I think after 3 they do mine but they really don't look happy so I unplugged them asap.

jaycar sells those aswell.

2 more RPI reboots during the night...

UPDATE: One more reboot during the morning...

im wondering if the arch Linux has updated a usb driver or something as I had been unable to get v0.2.3 running for more than a couple of minutes but once I read the last few posts and unplugged my 13 port USB hub it now seems to be running ok. my belkin 4 port hub seems to work ok.

does Linux have a USB hub driver? has it been updated since v0.2.2

maybe arch Linux doesn't like some hub chipsets. is there a command to see the details of the USB hubs plugged in.

does this sound possible?

oh and the exact same system has been running ok with v0.2.2 but it was crashing every few days.

also to the person who couldn't use past the 3rd port, I would suspect there is 2 or more chips in the hub of 4 ports each. and once you hit the second chip it seems to be funny.

Glad am not the only one..I can get 0.2.3(a) running but its like a disco on my erupters (22 randomly going idle) where as on 0.2.2 there 100%

This time it was "the worst case scenario". cgminer frozen for as least 1 hour, until I saw my hashing graphics @ Triplemining.com and connected home and had to reboot the RPI.

I could connect to the RPI via SSH, enter screen mode, but cgminer was frozen, not updating the display or accepting commands. I had to force a "sudo reboot" to reboot RPI. It was 13:05 and cgminer stopped working @ 11:56:17, as can be seen in this print screen:

[Scorpia]

also some other things ive noticed with 0.2.3a.

the status page asks you to click the login prompt every time you select it but it does remember the password at least.
also on the advanced page there is no dropdown for the timezones.

Also I have got a "dolphin" USB 3 4 port hub and it seems to work ok. so its only some USB hubs that are causing an issue.

[ninjaboon]

also on the advanced page there is no dropdown for the timezones.

For RPI, setup your location zone

Code:

timedatectl list-timezones

Then enter your Zone into the following:

Code:

timedatectl set-timezone <Zone>/<SubZone>

example:

Code:

timedatectl set-timezone Asia/Kuala_Lumpur

Then update the Time:

Code:

sudo ntpd -s

or

Code:

/usr/bin/ntpd -s

And when I first booted my RPI, it could not get an IP from the DHCP server.
So this command will do the trick after bootup:

Code:

 I get reboots every hour or so. Sometimes every few minutes. Not sure what wrong.

Upgraded MinePeon 0.2.3a to cgminer 3.4.0, to see what happens next... 

[r7970]

The pi gets hot really fast. If it is rebooting the heat may be the problem. Try cooling it down.

temp 40.1 °C... I have the RPI vented with a fan.

Upgraded MinePeon 0.2.3a to cgminer 3.4.0, to see what happens next...  

Started @ 20:05 and @ 20:50, RPI rebooted. New reboot @ 21:59.

[teletobi]

I'm running 0.2.3 for 3 days 1 hr 14 min 36 sec now. No reboot yet. Only the Miner reboots once a Day when Internet is forced to reconnect.

here's my bugs report
minepeon@0.2.3

Bugs in the WebUi:

advanced page

why the static page dont show the Mh/s of the devices? on the advanced page the hashes are good 
why are the graphs all fucked up, (in Kh/s) 

year 1970 ( i know, the RPi dont have internal battery to save the date, but in 0.2.2 it was good)

the Rpi reboots 2 times/day, and when it does i've to unplug it and the modem, plug in the modem and when its ready plug the Rpi 
if i dont do this, the cgminer never starts again, because it cant find an IP, idk 
if i'm not at home do to this, i lose mining time

what USB hubs do you have connected?

an you disconnect all but one and see if it works with one then add more.
if they are different brands try the different ones to see if one is stable.

I find with mine that when it boots up the ntpd sets the time. once that has happened if you restart the miners (click submit on the pools page) it seems to fix up the issues with the graphs and not seeing the devices Mh/s



Also mine ran overnight . so one now has 12 hours uptime and the second has about 7.5Hrs since I changed the hubs around.

Maybe the newest versions of MinePeon are somehow incompatible with bfgminer.

I will check into this when I get home, it would be a bit of a bummer if it is true.  The only reason I have been able to support both bfgminer and cgminer is because the API is the same and if they start to differ there is going to be problems.

That makes sense.  Let me know what you find out.
