scrypt only mining, just use the version on github. Have a look the readme file to know how to build it for Linux. The dip switch is very important. It changes the voltage of electricity. To get higher scrypt mining performance, switch it to L. When the switch is on L. You can mine at 850Mhz. Otherwise, only 600Mhz or below be used.

From the above example I am using

cgminer.exe --scrypt --lo -o stratum+tcp://ltc.give-me-coins.com:3333 -u TomInVa57 -p 12 -S //./COM3 --dualminer-pll 850

the only thing that happens is the cgminer command window opens and immediately shuts down.. Switch is in LTC mode only.

NOTE: Pay attention to the device name in command line. There are two serial port devices appear if the VCP driver installed successfully. One for BTC nonce report, another for LTC nonce report.

For example, if you see COM3 and COM4, usually COM3 is BTC port, COM4 is LTC. In some rare case, COM4 is for BTC, COM3 is for LTC.

To do a LTC only mode mining(--lo is given), please give the BTC port as the device name. In this mode, the chip is configured to report LTC nonce to BTC port.
In dual mode, make sure BTC mining process uses BTC port, LTC mining process uses LTC port.

I did get it compiled on my Pi today, running the latest Raspbian image. What seems to be the problem?

Are you able to mine with it on pools with confirmed shares?

For the life of me I can not get this to install on my Pi, I can configure everything but when I go to make && make install it will not work. I am not very talented with linux, so if someone would be so kind to break it down barney style for me I would really appreciate it.

I got cpuminer compiled on my raspberry with rasbian successfully, too. But when I start mining, I have the same problem as I have on my gentoo box.

What error are you getting when you run "make" and how did you configure the build?

Hi,

One more question, can we mine all "Scrypt coin" with the Dualminer ? Or only the LTC ?

dualminer_3 are you working for dualimer.com?

I ran 2 miners the whole night and looks like they are doing their job

However, the pool does not recognize any mining activity....

Also I just got a reply to my support ticket from dualminer.com (Herb):

the only thing that happens is the cgminer command window opens and immediately shuts down.. Switch is in LTC mode only.

Previous version software supports dual mode. If you use previous software on Windows, you can do dual mode with following commands.
We have to start two cgminers. One is for BTC mining. Another is for LTC mining. This two process use same exe file.

Start BTC mining with command:
cgminer.exe --dualminer-pll 500 --dualminer-btc 64 -o stratum+tcp://btc.give-me-coins.com:3335 -u xxxxx -p xxxx -S //./COMxxx

COMxx is the device name on Windows. --dualminer-pll is for clock freq. --dualminer-btc is for how many units you want to open
Start LTC mining with command:
cgminer.exe --scrypt -o stratum+tcp://ltc.give-me-coins.com:3333 -u xxxx -p xxxx -S //./COMxx
--scrypt is for scrypt mining.

If you just want to mine LTC, you can use:
cgminer.exe --scrypt --lo -o stratum+tcp://ltc.give-me-coins.com:3333 -u xxx -p xxx -S //./COMxx --dualminer-pll 850

The --lo param forces cgminer only mine LTC. In LTC only mode, only one cgminer is needed

The version on github doesn't support this dual mode. We will add dual mode support by next Wednesday. After this work done, you can do a dual mine with just only one cgminer.

Thanks for your quick reply dualminer_3,
that helps a bit more to understand the dual mining configuration in general and I hope this will be more clear in the future, especially for non windows systems.

But as the main purpose of this chip is scrypt mining, what is the best way to mine scrypt-only so far on linux?
* does the position of the hardware switch matter at all?
* and which mining software is currently working for that on linux ? cpuminer/cgminer ? which version or fork is recommended?

Cheers

You're not going to make much money dual mining. Put it into LTC mode and mine alts. Much more profitable.

I was not asking about profitabilty.
I am just curious about the dual mining capability as this is the first miner with a gridseed chip available to most of us, isn't it?
There are more devices to be released in the near future and I haven't seen any information regarding the pool configuratiion in dual mining mode.

More important right now: At the moment, I see that cpuminer seems to be doing his job in the shell, but I don't see any confirmation from the scrypt pools about that either.
Did anyone have success with it so far?

Cheers

I just got 2 of those miners and got them recognized on gentoo linux with https://github.com/gridseed/cpuminer.git

But I haven't found any information about the dual mining mode so far, not with cpuminer nor the cgminer forks.
How is it supposed to work, I suppose you need to define two pools, one for sha256 and one for scrypt?

I will offer up a .05btc bounty for anyone who can post step by step instructions for setting these up on a beaglebone black; from setting up the beaglebone to up and running with the USB's.

I am currently using the GUI and I have no problems with it reaching full speed.
Make sure the LTC only is checked.
Also make sure your hub is giving it enough power. Some hubs to not supply enough.

you should look in to why these miners die after x amount of hours

I haven't had problems with mine going down on my Windows 7 box at all. The speed isn't what I expected out of them though.

You're not getting the 70kh/s each? I have 30 with no issues on any of them.

I'm getting 25-35kh/s per a single one. I know that is the # if it is in dual mode but I'm 100% sure I have the switch flipped to L. I tried it the other way around and got the same hashrate.

Any trick you had to do? I'm running these without the GUI. Maybe I need to change my batch script.

They do run nice and cool but a fan on them is always a good idea.
I have an Arctic Breeze on mine.

Just got mine today. Bought 10 on the website and had them at home in 3 days (Netherlands). Now setting up the rig, using the new software from github. Got it running on my Linux mint eeepc. This weekend i'm setting up the raspberry pi.

Do you use fans on these in a usb hub or just passive cooling?
