[Minera v0.9.1] Your next mining dashboard - Antminer/CPUminer/CGminer/BFGminer

[michelem]

Are there plans to make a RPI2 version?. Also I have forgotten what the ssh login is for the RPI. Can someone tell me what the default is pleze. Thanks.

Raspberry PI 2 must work as is, nothing changed as architecture, it has only much memory and cpu, so it is really weird Minera doesn't run on it. Let me buy one and I will investigate, but you should try connecting a monitor to see what it says.

Default user/pass for Minera are minera/minera for SSH and "minera" for web.

hi again,

is there a option to set the frequency for each miner alone?

at the moment i have the "manual setup" with this command line:

--scrypt --scan-serial zeus:auto --zeus-chips 6 --zeus-clock 350 --api-listen --api-allow=W:127.0.0.1

but i want to set the clock rating down for one of the two miners.

for example:

ZUS0 = 340
ZUS1 = 350

Thank you :-)

Please refer to this: https://github.com/dmaxl/cgminer/
You need to setup the command specifying --zeus-options for each device, read it carefully.

well i tried but miner won't start



[2015-02-27 16:16:21] ZUS0 opened on /dev/ttyUSB0
[2015-02-27 16:16:21] ZUS1 opened on /dev/ttyUSB1

Miner works: --scrypt --scan-serial zeus:auto --zeus-chips 6 --zeus-clock 340 --api-listen --api-allow=W:127.0.0.1

Miner doesn't start: --scrypt --scan-serial zeus:auto --api-listen --api-allow=W:127.0.0.1 --zeus-options /dev/ttyUSB0,6,350;/dev/ttyUSB1,6,340
2nd try - doesn't work too: --scrypt --api-listen --api-allow=W:127.0.0.1 --zeus-options /dev/ttyUSB0,6,350;/dev/ttyUSB1,6,340

hum...

Thanks for the reminder on the ssh login. On the RPI2 as well as the Banana pi there seems to be an issue with the boot loader. It will just sit there and do nothing. It appears it sees the card but will not load it. I think the reverse is also true. If ya do up a card for the Banana or the RPI2 they will not boot a reg PI. Not sure why not but it has to do with the boot loader looking in a different spot for whatever it needs to continue on loading.

Oh well, I read about upgrading the Raspian OS (that one Minera runs). You could try to do this:

From your old Raspberry PI with Minera, SSH into and:

sudo apt-get update
sudo apt-get upgrade

After finishing, you should have an SD Card ready for RPI2 too.

Refer here: http://thepihut.com/blogs/raspberry-pi-tutorials/16982376-updating-raspian-on-your-microsd-for-the-raspberry-pi-2

@ammi84 I'm sorry I haven't that kind of devices, perhaps you could try look at github page of the miner fork (search for an issue) or some more specific related forum thread (it's not a Minera problem it's only a cgminer setup)

[ammi84]

Thanks :-)
i try go get lucky here https://bitcointalk.org/index.php?topic=644921.msg10600907#msg10600907 and in Litecointalk - i will report when i get new informations

I did the raspberry PI update/upgrade. Used sudo raspi-config and expanded the file system all the way out. rebooted the pi then did a shutdown. Pulled the card and put it into the PI2 and it came up just fine. The update when it in the rpi will take almost an hour but it seems to fix the boot problem on the rpi2. Works like a champ now.

Great! Thank you for the feedback! I will put the info in the official README

just an update. That trick does not work on the Banana PI. Going about that in a different way. Going to load up rasperian for the Banana and just run it in command line mode then try to install the Minera on it. I may or may not get it going as I'm about as far from a Linux guru as someone can be. But I'm also stubborn as hell and hardware and software will bend to my will! Has anyone else got Minera running on a Banana?

Minera 0.4.1 is out!

* Added pool proxy setup
* Added Github star button
* Added algo info to the stats
* Added auto switch donation pool based on algo (you can now donate mining time in SHA-256 too)
* Fix sending empty stats to mobileminer
* Pools bug fix
* New Minera image with Raspberry PI 2 support (Please refer to this wiki page if you are updating via web)

Hello guys, while I'm still working on Minera 0.5.0 with network devices support, I'd like to release this new minor version that fixes some bugs and add some small changes.

0.4.1 image is in upload, it will be ready by this evening I think, but I will update you as soon as it finished.
New image has also support for Raspberry PI 2, while if you are updating by web you should read this wiki page and manually do the system upgrade needed by RPI2.

Hope you like it!
Have a great weekend!

Thank you for another update The pools bug fix you refer... Do you refer to that bug when switching pools occurs?

Yes that should be fixed now. Please let me know if you see it again.

0.4.1 image build is ready!

Hello, i'm still on 0.3.8, are these commands still ok to update?

Code:

cd /var/www/minera
sudo git fetch --all
sudo git reset --hard origin/master
sudo ./upgrade_minera.sh

Thanks

Yep, but from a so old version I recommend a complete SD Card backup too if you can.

This software setup is the best!
I struggled for a week with other script mining options with a raspberry pi.
Thanks for making it easier for a newbie to start mining cryptos.

With that said, is there a way to remove the failover pool setting going to donations? It says that it will be removed but always comes back after a save or after a save and restart miner. I don't mind donating since I give a percentage of my hash power on the main control panel page.

Are you speaking about remove the donation pool? you have to remove it from settings page and save&restart. What does happen? Did it come back? What Minera version do you have?

[dukester99]

Yes I have tried saving and restart

I am running 0.4.0

[michelem]

Yes I have tried saving and restart

I am running 0.4.0

Can you change/remove/add other pools? Is it related to only the donation one?

[dukester99]

Yes I can add and change pools no problem.
