Custom cgminer build from dualminer that just committed to github: https://github.com/dualminer/dualminer

Thanks, I haven't tried that one yet, I just compiled it and it seems to be working. The first shares are getting recognized by the pool.

Which miner software are both of you talking about? Where did you download it?

@poopypants, you can run chmod +x autogen.sh , this should maybe fix your permission problem.
But you don't need to build it with sudo (root privileges), so if you did that before, this might not work. If you did that, try to remove the build directory, download it again and start from scratch without sudo.

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?

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.

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):

Linux mining will be coming soon. Watch the Support section of our website for that info.

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?
