GekkoScience Terminus R808 Miner Official Support Thread

[sidehack]

The first post says build instructions are the same as for the 2Pac, so I'd check the build instructions in the first post of the 2Pac Support Thread.

Pending new revelations to my situation, I think my controller won't be able to handle more than one of these at a time. Sidehack said he can get 2 running at a time off a raspberry pi, so 2 Pi's should let me run my 4. I tried following the directions on the 2pac thread and couldn't do it.

Anyone with the patience to talk me through a raspberry pi setup? We can do it here to benefit everyone, a new thread if it's tangential, or by private message.

I need to know:

1) do these need drivers on a pi? How do I find and install them properly?

2) instructions I've seen discuss "building" cgminer. How do I do that?

If you already have a running RaspPi then https://bitcointalk.org/index.php?topic=3009183.0 should help you out.
Look for "or Raspbian - Kernel version: 4.4 (Raspberry Pi)". It has listed all the steps needed to build cgminer.

In the post you can also find commands to run cgminer (look for *nix)

What's not said in the post is that you should probably run screen first and then run cgminer so you could disconnect ssh session and leave cgminer running.

I've created a modular tray design for the Terminus, 12v PSU and rpi which should make them easier/neater to run in larger quantities. I should have a limited amount in stock soon.

All that does is link to the top of this thread. Sidehack says to check out the 2pac thread, but those instructions aren't clear either - they are written for someone with a basic understanding of coding and that is most definitely not me. I had to spend hours trying to figure out how to make sense of that code at the top of the thread in order to even get CGminer on the pi. Basically I can get an instance of CGminer up and running, but I can't get my miners recognized on the raspberry pi. Is there a driver for it? Zadig is Windows specific and nothing else is mentioned on those threads about doing that.

I still have to run cgminer by clicking on the icon in the git folder now that I've followed the steps up above. I can't figure out how to run a .bat file from raspberry pi. I'm not a computer guy so these explanations are somewhat over my head.

What I'm stuck at now is that I can't get my pi to recognize the miners and I don't want to manually copy/paste my information into cgminer each time I start. Is there an equivalent of a .bat file for pi like I run on Windows?

[minerbobbert]

The first post says build instructions are the same as for the 2Pac, so I'd check the build instructions in the first post of the 2Pac Support Thread.

Those instructions are nearly identical to the ones on the top of this thread. I've been able to figure out how to download CGminer following them, but that's about it. The instructions are not simplified to the point where someone like me can follow, which is why I asked here if anyone could help me through it.

[sidehack]

You do know that the build instructions are done entirely by typing everything (or copy-pasting) into a terminal, exactly as it's presented, right? Put in one line, hit "Enter", wait for it to do its thing and get you back to the shell prompt, and then punch in the next line. Should take minutes. Except for the "apt-get install" all the dependencies line, I've pretty much got the whole thing memorized by now.

Uhmmm. Maybe? I think I followed the directions up above by copy/pasting each command serially as you say. When I was done there was just a new command prompt, no cgminer. Does that mean I built it? How do I know if I did it correctly?

I had to open the git file it linked to and find the cgminer executable file, which I can bring up but it won't recognize the miners and I have to copy/paste everything into it to get it started (pool address, my Bitcoin address, etc.  The same stuff I use a Windows .bat file to do).

[sidehack]

The "make -j 2" line is where it compiles the program. Once that line runs, your terminal should be pointing to the folder where cgminer was compiled.

After that, you run the "./cgminer -o"whateverelse line like under the "How to Run" part of the post. With your pool configs instead of the sample ones.

If you're following the directions and somewhere you think you're required to click on something with a mouse, you're probably doing something wrong.

Also what you're doing is not coding, has very little to do with coding, so coding knowledge is mostly irrelevant. What you want to learn is how to navigate a Unix/Linux terminal. Basically equivalent to DOS shell in Windows, just a whole lot better.

If you followed the instructions, cgminer should be living in the git/vthoang directory within your home directory. When you open up a new terminal, type " cd git/vthoang" and then to start cgminer type the run syntax "./cgminer -o (POOL INFO) -u (USERNAME) -p (PASSWORD)". Worse case if it doesn't want to work properly, recompile everything and try again. All the instructions worked like a charm for me running a few 2pacs for fun on a Pi and I literally knew nothing about Linux at the time so there is no reason it shouldn't work.

I'm sure there is a way to make it all run automatically along the lines of a .bat file but since you should not have to be starting/stopping the program all the time I never bothered to figure it out.

[thehypnominer]

Well heck, looks like you got the very first one off the line. Check that serial number.

If it's detecting all 8 chips, the issue almost has to be with your hardware or software setup rather than the miner. Those numbers don't make sense to be a miner issue.

I'm honored!

Also, I solved the issue. Turns out that (maybe just with my particular setup) the Terminus really dislikes USB 3.0 ports. I tried 3.0 ports both on the case and mobo and it always seemed to be capped out at hashing about 10GH regardless of the frequency or V. However, when I plugged it into one of the mobo 2.0 ports it immediately began hashing about 75GH at 175Mhz - right where it should be.

See? I'm enough of a computer illiterate I didn't even know that.

I followed the instructions here and I have been able to get CGMiner to run, but it isn't recognizing my miner. Any advice?

[sidehack]

The error, and to a certain extent its solution, is here:

Code:

I bet if you look into cgminer's included README file for that error you'll find some advice.

Or you could check the FAQ section, which includes this little tidbit:

Q. How to get past "USB init, open device failed" ... "you don't have privilege to access" error.

Code:

cd ~/git/vthoang/cgminer/
sudo usermod -G plugdev -a `whoami`
sudo cp 01-cgminer.rules /etc/udev/rules.d/
sudo reboot

[minerbobbert]

Yup! That was it!

I got both units running at a breakneck 84 ghash on a single Raspberry pi.

Thank you so much for your help everyone in getting a dunce up and running.

When my 2 new units arrive, I could always just set up a second pi to get them running.

I eagerly await your next project!

A couple of final questions:

1) Sidehack himself said he couldn't get more than two running to a pi. Given that there's only 4 usb drives and you need a keyboard and mouse I'm not even sure how you could pull that off without a USB splitter. If anyone figures out how to run 4 off a single pi, let me know.

2) Maintenance on these guys: is there any need to unplug them occasionally? Or does running 24/7 until they break not matter?

I just got my first Pi. Haven't been able to pull it off with these ... yet.

I have three open USB ports on the Pi - USB wireless keyboard/mouse, so I'll shoot for that, someday.

[Jgreen0708]

Apologies in advance for asking this as I have difficulty finding the answer..

What algo can it handle? Scrypt or SHA-256? The expected 66 GH/s is for what algo?

Many thanks in advance

[sidehack]

Is it a good enough hint that this is posted in the Bitcoin section?

[Jgreen0708]

Is it a good enough hint that this is posted in the Bitcoin section?

Ok, then I presume it's SHA-256 only? I don't want to assume, that's all as sometimes miner hardware can do multi algo,

Thanks for replying..

So it turns out that I shouldn't have spoken so soon. I only managed to get it working for a short time. Now cgminer is failing to detect any of the chips on the Terminus. My log file reads as follows:

I'm using the most recently posted build of cgminer, and I have tried reinstalling and troubleshooting the Zadig drivers. Any suggestions?

[kipper01]

Been running at 200Mhz for 3 days.  Average has been steady right around the reported rate for 200Mhz.  My question is the HW errors normal?  Core voltage is set at the 'factory setting'  Would adjusting that decrease or increase errors?

[sidehack]

That's not very many errors. If you think of it as a percentage of accepted shares (all of which are in the neighborhood of 5.3 million) and also as accumulation over 3 full days, it's almost trivial.
