Setting up the sandor111 for my 2 gridseeds, I get some errors.

Here is my screen:

Post the json you're using. Stock I am guessing?

I used the stock json. I also started it from a CMD Prompt, no json, autodetect. same error:

Pool info incomplete, seems like you forgot the pool URL, user and pass.

Nice catch...was going to suggest checking 12v power.

[sandor111]

He might want to edit the json with notepad and add the following, but he needs to change the pool:port,username and password.

Code:

{
	"gc3355-detect" : true,
	"gc3355-freq" : [
		"8D9117765449:850:0", "8D9117765449:850:1", "8D9117765449":850:2", "8D9117765449:850:3", "8D9117765449:850:4" 
		"8D76576C5355:850:0", "8D76576C5355:850:1", "8D76576C5355:850:2", "8D76576C5355:850:3", "8D76576C5355:850:4"
	],
	"gc3355-autotune" : true,
	"pools" : [
		{
			"url" : "pool:port",
			"user" : "username",
			"pass" : "password"
		}
	],
	"freq" : "850",
	"debug" : true,
	"log" : "log.txt"
}

After auto tuning for what 12-18 hours, he needs to check the log to see where optimal performance is. Then edit the json and remove and add "edit" the frequencies to each chip "0 1 2 3 4"

BTW, no need to specify the frequency for each chip if they're the same, I believe that bug was fixed recently.

aChingCoinDev does it work if you bypass the config file and run a minimal .bat file? e.g.

Code:

minerd-gc3355 --freq=850 --gc3355-detect --url=stratum+tcp://us-east.multipool.us:7777 --userpass=brandonb01.1:x

pause

[favelle75]

New issue with one of my Blades. Every so often, I'll get one of the Blades having a "USB failure". Of course, using CGMiner, this kills the program and then ALL the Blades stop mining. 

I've tried using a different USB cable and I've tried a different power source. Nothing changes. When its mining, its awesome. Fast. I was running everything at 838Mhz, but I've gone back down to 800 to see of that was the problem. Nope, every time, eventually, there will be a USB failure and CGMiner has to shut down.

Search for FIFO Buffers in this thread.
Your solution may be there.
Good luck!

Thanks Wolfey, I'll check it out right now!

You have to let it sit for about five minutes the HR will climb. Try it. I see 0 for MHz. HMM.

Nope. After 30 minutes, still no change. Some more "New Job_id", but that is it.

[KaChingCoinDev]

I am sorry, but I don't understand why it is not working.

Maybe someone could chip in.

I am officially lost withit. It's like they just dont want to work.

They work with cgminer 3.7.2 (mostly)

Thanks for trying to help!

I think you're looking in the wrong place for the cause/solution.
It says it's receiving new blocks. It doesn't matter if the chips aren't hashing. 0.00MHz means DEAD! NUTTIN! NADA!

They are not firing up. When they do, it's almost instant before you start seeing accepts, there are chips firing up and hashing away. That's the only way it works.
Something is not starting the chips up. Perhaps a missing command? Perhaps a bad comm line between machine and controller? Are you using a PC or a controller?
I've seen this happen when the FIFO's get gummed up or the USB chips aren't working correctly and require a reset. Try disabling and re-enabling them.
Unplug and plug them back in then try.
Anyway, make sure your command line is all straight first, then if no joy, check your communications hardware.....
Good luck!

Working with CGMiner? Well I think that means you have to uninstall the WinUSB com ports you installed with Zadig? Because thats the configuration thats needed for CGMiner to work. For CPUMiner you just need to install the Virtual COM port driver. So if its working with CGMiner its not going to work with CPUMiner until you do that. That is my experience, at least.

[KaChingCoinDev]

I know whats wrong... It happened to me but i forgot.

Shutdown sandor cgminer.

Uninstall zadig from device manager under Ports com & lpt.

Now download and install  this driver to your OS. install the 32bit if your OS is 32bit, install 64bit if your OS is 64bit.

Get rid of zadig as I mentioned prior.

Install

https://www.dropbox.com/s/cys6f7xh7kh1y6i/stsw-stm32102%20%281%29.zip?m=



After you install this driver

your com port under device manager should look like this.



Fireup sandor111 cpuminer with

Fantastic!

That one question I would not know I never experimented with nor do I know if the program is capable of doing this such type of work.

Okay. I know with CGMiner you can tell it to use device 0, and the other one will be off

Press any key to continue . . .

Edit:
The dev or someone else with knowledge to this might want to chip in.

Edit2:
My best guess is run single folders of the json configured.

Okay

How do you tell the JSON not to use a certian gridseed?

Hi,
   I received 2 Gblade yesterday. I have them connected to a Win 7 64 and they do not submit work. I tried with cgminer and Winusb drivers installed through zadig and everything seemed to work, Cgminer showed 10,4 Mhs but nothing was submitted.

Afterwards I tried what KaChingCoinDev suggested  and again, nothing was submitted.

Any idea?
Thank you in advance

Okay

Probably something like this?

EXAMPLES.
Code1 would be json 1 in folder 1

Code:

{
	"gc3355-detect" : true,
	"gc3355-freq" : [
		"8D9117765449:850:0", "8D9117765449:850:1", "8D9117765449:850:2", "8D9117765449:850:3", "8D9117765449:850:4" 
	],
	"pools" : [
		{
			"url" : "stratum+tcp://us-east.multipool.us:7777",
			"user" : "brandonb01.1",
			"pass" : "x"
		}
	]
}

Code2 would be json 2 in folder 2

Code:

{
	"gc3355-detect" : true,
	"gc3355-freq" : [
		"8D76576C5355:850:0", "8D76576C5355:850:1", "8D76576C5355:850:2", "8D76576C5355:850:3", "8D76576C5355:850:4"
	],
	"pools" : [
		{
			"url" : "stratum+tcp://doge.ghash.io:3333",
			"user" : "user",
			"pass" : "x"
		}
	]
}

Not sure if that would have the desired effect. If both instances are using auto detect, then I think they'll both try to run both gridseeds at the same time - even though you are only specifying the frequency for one specific device (the readme says a default of 600 is applied if nothing is specified). If you're going to run 2 instances you probably need to specify each device rather than use auto detect? Just an idea.

Hey, for anyone in the know....how many GS Blades can you connect to a Rasp. Pi? I have 8 connected to a laptop, can the Pi handle 8?

[CartmanSPC]

Got it working!!!

How do I specify which device to use? I would like to point one gridseed to one pool, and the other gridseed elsewhere

Fantastic!

That one question I would not know I never experimented with nor do I know if the program is capable of doing this such type of work.

Okay. I know with CGMiner you can tell it to use device 0, and the other one will be off

cpuminer does not support concurrent mining to different pools like cgminer. You will have to specify specific devices under different instances with cpuminer.

I tried that, but then it went back to my old issue of failing COM port. Work never gets sent to device.


P.S.

Is there any way to solo mine with this. I tried, but it keeps trying to start stratum and finds it cant.
