[GUIDE] GridSeed GC3355 5 Chip Setup/power/windows/linux/rpi by UnicornHasher

please tell meee
screen split automatically

I think that was done by hand not by script...

http://www.gnu.org/software/screen/manual/screen.html

or an easier guide: http://tomlee.co/2011/10/gnu-screen-splitting/

thank youuu
i can study

EDIT: if you are using the root account and have files stored in /root/ you will have to change all of the /home/miner/ paths to /root/

Oddly enough I can make that setup happen via script:

pool0.sh - pool9.sh

Code:

POOL="-o stratum+tcp://us.clevermining.com:3333 -u 13zKJjzxGpjbqJDAWAhFNHVqALqcsCWiat -p x"
FREQ="800"

cd /home/miner/cpuminer/
./minerd -F $FREQ -G /dev/ttyACM9 $POOL

aio_screen

Code:

screen -t miner0  /home/miner/pool0.sh
split
split -v
focus down
screen -t miner1 /home/miner/pool1.sh
focus down
screen -t miner2 /home/miner/pool2.sh
split
split -v
focus down
screen -t miner3 /home/miner/pool3.sh
focus down
screen -t miner4 /home/miner/pool4.sh
split
split -v
focus down
screen -t miner5 /home/miner/pool5.sh
focus down
screen -t miner6 /home/miner/pool6.sh
split
split -v
focus down
screen -t miner7 /home/miner/pool7.sh
focus down
screen -t miner8 /home/miner/pool8.sh
split -v
focus down
screen -t miner9 /home/miner/pool9.sh

Then as root run

Code:

 screen -c /home/miner/aio_screen

Should output 10 consoles like this: I only ran one actual unit in the window as a test.

The only issue I had was that upon detaching and reattaching to the screen session or starting detached all of the windows reset to windows with no positioning

Thank uuuu
very helpful

miner0~9.sh

Code:

mkdir -p home/cpuminer/miner_conf;for i in {9..0};do echo -en "POOL=\"-o stratum+tcp://pool -u worker -p x -q\"\nFREQ=\"850\"\ncd home/cpuminer\n./minerd -F \$FREQ -G /dev/ttyACM$i \$POOL" > home/cpuminer/miner_conf/miner$i.sh;done

change permission for miner0~9.sh

Code:

chmod -R 755 home/cpuminer/miner_conf

my_screen

Code:

screen -t m0 ./home/cpuminer/miner_conf/miner0.sh
split -v
split
focus down
screen -t m1 ./home/cpuminer/miner_conf/miner1.sh
split
focus down
screen -t m2 ./home/cpuminer/miner_conf/miner2.sh
split
focus down
screen -t m3 ./home/cpuminer/miner_conf/miner3.sh
split
focus down
screen -t m4 ./home/cpuminer/miner_conf/miner4.sh
focus right
screen -t m5 ./home/cpuminer/miner_conf/miner5.sh
split
focus down
screen -t m6 ./home/cpuminer/miner_conf/miner6.sh
split
focus down
screen -t m7 ./home/cpuminer/miner_conf/miner7.sh
split
focus down
screen -t m8 ./home/cpuminer/miner_conf/miner8.sh
split
focus down
screen -t m9 ./home/cpuminer/miner_conf/miner9.sh

then as user run

Code:

screen -c my_screen

good working!!

Best performance cpuminer fixed.
you should work on firmware !!!!!!!

Nice rig!

"Best performance cpuminer fixed" What was fixed exactly?
Can you be a bit more specific and clear on what you're talking about?
Clue us all in?...
Tanks!

OK are are pictures of before in device manager and after in device manager when Zadig program is run and WINUSB is applied. Note that after STM32 is still in device manage but now listed under USB devices instead of com ports and it no longer has a com port assigned to it.




I i could figure out a way to assign a com port maybe I might be all set

[SummersideGuy]

Using Com1 seems to let cpuminer detect the gridseed however when running, it is not solving any shares , see my screen grab below

[daddyfatsax]

I can get into cgminer, but I keep getting this.

[daemonfox]

I can get into cgminer, but I keep getting this.

close cgminer... unplug your usb... plug it back in and count to 5... launch cgminer.

[daddyfatsax]

Did that. Then 2 or 3 will start. I had 5 going first as a test before I got the other 14 wired up. Maybe there is an issue trying to do so many in cgminer.

i had 10 wired up and it starts right up... hows your hub being powered? also hows your raspi being powered? usually when it detects and it doesn't is a clear indication of underpowered ports...

Hubs are powered by adapters. I have a Anker 9 port and 12 port that came with the accessory pack. I am using Win 7 x64.

The best is cpuminer for Gridseed 5-chip GC3355 ASICs with Reduced Power Usage

[daddyfatsax]

I cannot find the link for the COM port drivers. Can somebody post it please? Gotta head to a client dinner. Thanks.

hear, hear!

Definitely up there where it comes to plug and play-ability!

I've read that 2.1mm jacks fit the GridSeeds, but it isn't clear if they fit loose, or make poor contact at the tip or not. Does it really matter between 2.1mm & 2.5mm? The 2.5mm jacks are somewhat hard to get locally.  

If the plug was designed for 2.5mm, how can it even fit a 2.1mm? It shouldn't even go in the socket. 2.5 will fit into a 2.1, but loose; not vice versa.

I'm using both 2.1 and 2.5 with no issues.
2.1 fits the center conductor a bit more snugly, which is exactly what you want if your miner is pulling a lot of amps!

Go for it!

Thank you very much. 

[chanberg]

I second that. 2.1 fits way better!

[jmordica]

Has anyone figured out how to run the cpuminer for gridseed 5-chip as a service? I don't like having tons of windows opened

[suchmoon]

Anyone who has a Rapsberry Pi should try this:

https://litecointalk.org/index.php?topic=9908.msg138204#msg138204

Works perfectly for me.

Actually even if you don't have a Raspberry, just buy one. No messing around with junk controllers, no Windows USB drivers. Plug and play.

Is HW rate calculated by (HW/(HW+Accepted difficulty shares+Rejected difficulty shares))*100 to get a percentage? If so, it seems I have 0.16% HW rate at 900Mhz. Using leaserig an an indicator, even though the hashrate is stable in cgminer, it jumps around like a crazy sine wave on leaserig stats graph.
