[GUIDE] GridSeed 5-Chip USB, Blade & Black Miner Support/Tuning

[Mike Scofield]

Do i need an SD card for RAZPI?

[jjj0923]

yes - the recommend an 8 gb card - I bought one with the card and a 24 port hub.

[flounderella]

ok - I just followed the directions on Post #1 of this thread for: STEP BY STEP RASPBERRY SCRIPTA INSTALLATION

and cgminer started right up

and is running just fibne

two questions - can it be run nohup - so that it can run even when I don;t have an ssh session?

and #2 - how do I get it to run and mine BTC simultaneously?


by the way - my pi rasberry is running 20 gridseeds

Jeff

Yeah I think I'm going to buy a raspberry pi now and scare my wife :p (as if a bunch of antminer s1s and 11 gridseeds weren't enough... well she did marry a geek) ... all you see is an sd card, sd card reader/writer, charger, ethernet cable and the model b, right? Do you initially need a monitor to set it up or can just remote login via ssh?

[jjj0923]

I have not heard a single good thing about the zadig software and everyone says to remove it, but I want to mine BTC and LTC on my gridseeds on my pi rasberry - has anyone figured out a way around the zadig software?

[jjj0923]

you need a monitor initially because it's IP address is unknown and even a scanner cant't find what has not been set.

I grabbed a TV and hookup it up via hdmi and had it running in about 45 minutes then it went to my always cool and dry basement where the mining equip is located. I give mine a static ip so after a reboot I always know where to find it.

Ah cool, that sounds straightforward. Thanks

In scrypt-only mode, do you really need so many fans... I'm thinking of using standoffs to connect two gridseeds to one fan. Does anyone see any issues with that?

Use screen:

Code:

screen -S miner

"miner" can be anything, it's just a name that you can use later to get back to it. This will give you a new shell. Start cgminer there.

Ctrl-A, then Ctrl-D will exit the new shell and will keep cgminer running.

To verify that it's indeed running in the background use this:

Code:

ps auxwww | grep cgminer

You can now disconnect SSH etc. To get back to your cgminer:

Code:

screen -D -r miner

That is incorrect.  By default the Scripta image uses DHCP and its actually quite easy to find the device using angryip scanner (http://angryip.org/)

Be sure to use the proper SSH port 7722 when connecting!

Or conversely you could just edit the miner_start.sh script in /opt/minerpeon/startup/ folder and replace the existing cgminer string with your path and custom commands.

With the updated info saved your config will be retained and automatically loaded everytime the RPI starts up (which can be handy if you experience a power loss or the RPI crashes/reboots on its own).

If you have access to your router you can find the IP on it. Alternatively you can ping around in your IP range, it will respond. Scripta runs SSH on port 7722.

Sorry can cgminer control more than 10 gridseed? Whenever I add an 11th, it does show up in cgminer with hash rate but never accepts anything?

GSD 10 is the one. I added them one by one with cgminer running



Here's the command line options to run cgminer:

--scrypt --gridseed-options=baud=115200,freq=850,chips=5,modules=1,usefifo=0 --hotplug=1

change --hotplug to 5

[Fior Sirtheoir]

GetResult error 7 in debug. Any idea what I have wrong?  It is also saying it is looking for a particular block but finding a different one.

Yup, tried that. Narrowed the issue to one of the 11 units. Tried cpuminer as well as bfgminer aswell. They can detect and start hashing but this particular gridseed never gets any accepted shares. I'm thinking its a DOA. Since its now isolated, I'm going to try to see if its possible to flash its bios or play with clock freq

Unlike the others, only a green light is blinking...

[Flep182]

Try changing the USB cable and/or position on the hub. Plus wiggle a bit with the powercable

Yes, was going to suggest you run it on it's own to isolate which one it is. Let us know if you get it to work! I also had one like you that would not get any accepted shares on scrypt. SHA worked though. Tried everything I could from different mining software to different hosts/controllers and freq's. Tried running it on its own for well over 12 hours but it would never get any accepted shares....and of course the pools wont show it since it is essentially not doing any work.

be creative - you can probably set it up lots of ways to get the lowest amount of power and cooling used for scrypt only mode

I'll be toying with 4 of my 20 to figure something out while the other run with their fans for now

I took my fan off since I only use scrypt mode... and it doesn't get hot. It actually seems to be hashing faster...

Will a standard AC adapter work for powering gridseeds? I have around five 12v 10a laying around and it's silent unlike standard gridseed PSU. Will they work to power 8 units each? Won't fry them or something?

Each GS miner requires about .75A for scrypt and 7A for dual mode.
Any regulated 12v supply should work...
Im using a combination of wall-warts and 12V @ 100A HP server PSUs from old G5 servers...
