=================
=Thanks To The Community=
=================
As with the original compac, this project would not have even been possible without the great support from the community.  
A big thanks to everyone who pitched in; whether through signature campaigns, discussion, product ordering, or anything else.


=================
=How to get a 2Pac=
=================
Check the current product discussion thread for the latest news and updates.

=================
=How to Run=
=================
At the moment, you will need to build cgminer with the latest gekko driver to mine with the 2Pac.

The driver is under active development in an fork of ckolivas/cgminer.  
A pull request will be redirected to the ckolivas/cgminer repo once the code approached a stable point.

Run syntax:

*nix [if not root level privileges, see Q&A]
./cgminer -o stratum+tcp://pool.ckpool.org:3333 -u 1BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr -p x --suggest-diff 32

Install the zadig generic WinUSB drivers from:

http://zadig.akeo.ie

If all is well, you can list and see the miner from cgminer.

Code:

cgminer.exe -n

Mac OSX Compiling with Homebrew

    El Capitan (10.11.6)

=================
=Expected Performance=
=================
The expected performance of the 2Pac is 0.11*MHz=GH.  For example, 150MHz gives 16.5 GH (theoretical expectation).

Rough chart of power draw:


2Pac running with default settings:


=================
=Cooling=
=================
If you run the miners over about 100MHz it is strongly advised to cool them with a fan.  The cooling requirements are fairly low and unless you're trying to run 250MHz or above almost any fan at all will do.

===============
=Basic Q&A / Troubleshooting=
===============

Q. Can I run this cgminer build with the original Compac?

Yes.  The original Compac will register with separate device name from the 2Pac.

Q. Can I run this cgminer build with other USB miners?

It is recommended to use the official cgminer build for better support of other devices.  
It is best to keep the 2Pac separated from other devices until this fork of cgminer can be regression tested.

Q. How can I set a different frequency for the 2Pac vs the Compac?

cgminer will accept one or both parameters for the stick.
--gekko-compac-freq 200 --gekko-2pac-freq 150

Q. How many 2Pac(s) can I run at a time?

One.  Review the power chart in the performance section above.  
You can add more sticks using a 1-2A per port powered hub (recommended).
Hub thread: https://bitcointalk.org/index.php?topic=1779423.0

Q. Something doesn't look correct..  

Here are some of the more common ways to address issue(s):

• Unplug and plug the stick back in.
• Isolate to test only the usb stick
          Remove any usb extension cables.
          Try a single stick without any other devices drawing power (usb fan, other miners).
          Plug into a into different computer.
  
• Check for and git the latest build of cgminer.
• Look through the README.txt file for relevant notes.
• Handling problems in Windows:
          Switch to linux Ubuntu or Raspbian.
          Enable High Performance in Power Options Setting.
          Try one cgminer.exe process per device with "--usb :1".
  
• Search for / post the details to this thread.
• Dealing with ZOMBIEs/OFF:
          ZOMBIE/OFF state occurs when chip voltage needs > voltage supplied.  
          Monitor usb port voltage drops, adjust frequency down and/or adjust potentiometer.
          Voltage Note
          Voltage Adjustment Photo
• HW Errors Increasing.
• cgminer stopping after N hours (1)
• cgminer stopping after N hours (2)
• Raspberry Pi (kernel) stopping after N hours.
• Problem with Intel USB 3.0 Controller.
• Solid white light.
• A note on repair requests.

Any email asking for support will be met with "If you didn't buy from me, talk to the person you bought it from."

Q. How do I get the latest version of the driver and code?

Updates to main cgminer and gekko updates will be checked in regularly.
If you are following along with the instructions, enter the cgminer directory, pull and rebuild:

Code:

cd ~/git/vthoang/cgminer/
git pull
...

Q. I tried the latest code and am certain the old one works better, how do I go back?

Code:

git reset --hard 495461c 
CFLAGS="-O2" ./autogen.sh --enable-gekko
make -j 2

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

======================
= cgminer on Windows =
======================

(!)... If you have access to linux, use the mxe based cross compile example in the post above.

(!)... If you just want the windows executable, read a little past the cross compile section in the post above for a pre-built cgminer.exe.


Building the cgminer.exe binary for windows on windows can be a bit tricky (not for beginners).

Follow the steps below in exact order.  If a step fails, most steps after it will fail also.

Once you have a successful binary, zip up the whole C:\MinGW folder for safe keeping.  
Chances are these instructions won't work, as is, a few months from now due to normal updates, but you might still be able to git pull and build updates.

Environment Used:
Windows 7, (should work for all WinOS supported by MinGW & Git)
MinGW Installation Manager (0.6.2-beta-20131004-1 - Tested)
Git for Windows (2.11.0 - Tested)



MinGW Installation Manager
http://www.mingw.org/ : Download installer : mingw-get-setup.exe

    Install Options:
    default all - "C:\MinGW\"
    Mark for installation - "mingw-developer-toolkit", "mingw-base"
    Installation -> "Apply Changes"

From Windows Explorer: (or you'll get errors later)
C:\MinGW << Security (Edit)<< Users << Full Control  
    
Paste the following into Windows+R to get a MINGW32 shell and init the home directory: "C:\MinGW\msys\1.0\msys.bat"

From MINGW32 shell:

Code:

echo 'export PATH=$PATH:/opt/git/bin:/opt/git/mingw64/bin:/opt/git/usr/bin/' > ~/.profile
mkdir /opt
exit

Install Git for Windows
https://git-for-windows.github.io/

    Install Options:
    "C:\MinGW\msys\1.0\opt\git"
    "Use Git from Git Bash only"
    default everything else -->>>
    

Return to MINGW32 shell and complete the build.

Code:

 ck has released a new version of cgminer this week, does this build include the latest code or the version prior?

[vh]

ck has released a new version of cgminer this week, does this build include the latest code or the version prior?

Yes, it includes all the latest updates from ck's repository.
Including some related to system libusb that has sent my windows build example back to the drawing board. 
   
The entry page to my repository should say "This branch is N commits ahead of ckolivas:master. ".
If it's ever "commits behind" just let me know.

[hurricandave]

It's not often that ck releases version bumps like he did this week. Even though he adds commits regularly.

[murasame2003]

Love the fact that this build reports HW for each individual stick. 

[gt_addict]

Just to clarify. The new cgminer incorporates the compac like the novak "gekko" version used too but there isn't support yet for the 2pac until vh has finished?

[murasame2003]

Just to clarify. The new cgminer incorporates the compac like the novak "gekko" version used too but there isn't support yet for the 2pac until vh has finished?

That's correct.
vh's clarification on Official cgminer 4.10.0 release: https://bitcointalk.org/index.php?topic=28402.msg17596575#msg17596575

cgminer 4.10.0 from vh's github does support 2pac.

Q. How can I set a different frequency for the 2Pac vs the Compac?

cgminer will accept one or both parameters for the stick.
--gekko-compac-freq 200 --gekko-2pac-freq 150

[ZACHM]

I will be getting this built and running tonight when I get home from work. 

[JaredKaragen]

Excellent!

Might I suggest adding a note for Raspberry Pi users that is is EXTREMELY HIGHLY suggested to use a powered hub and not the Pi's USB ports directly....  They have trouble even supplying enough current to a portable USB self-powered HDD... let alone a stickminer =)   I don't want to see people with unnecessary troubles related to this =)

[sidehack]

I don't know if it's in there yet, but yesterday I talked to VH about adding frequency support below 100MHz. I tested my stick at 3.8W at 100MHz, so about 75MHz and below should run on a 2.5W port. It is still definitely recommended to use a good powered hub, especially if you want to push higher frequencies.

[vh]

Yes, the lower frequency options is available in the current build via git.
Both the compac and 2Pac appears to be responding to it.   Bleeding edge right  


I can't argue that a powered hub is definitely the long term way to go.

The Pi3B might be a good starting device to use with the 2Pac.  
https://www.raspberrypi.org/help/faqs/#powerReqs.

You feed it a 2.5A power source, and it has a 1.2A current limiter out to the usb ports.
That give the stick up to 6W of power to work with.    

In the photo above, I have a 2.1A battery pack hooked up, drawing 3.88W @ 100MHz.

New numbers while connected to the Pi3B:

adjusting the potentiometer knob as low as it can go
(not sure what that translates to on my stick prototype)

Mining, no hwerror @ 75MHz = 2.7W
Mining, no hwerror @ 50Mhz = 1.9W

[sidehack]

On your stick I think I used different resistors that'll go to a bit lower voltage than the release model, probably 600mV flat instead of 630. I had trouble getting sticks to initialize stably in that low range so I decided to nix it.

I'll run my test stick at those underclock numbers tomorrow and add to the efficiency chart.

Why is this so hard to build?

Not complaining but asking.

If I go to ck his just zips open and I can run cgminer.

I will play with it in a bit.


Eyes are still too blurry I will wait a bit.

thank you.  I have ck's 4.10 build working with the compac.

I should be able to get yours going with the TwoPac  thanks again.

[ZACHM]

I have mine setup and running on a fresh install of Ubuntu 16.04.1 LTS. 

Thanks vh!

Just a little thing, but you missed the step about installing git in the instructions, not a big one, but you could easily add it in the line where you are installing everything else.

Thanks again.

[sidehack]

I built it on an older Debian fresh install, needed libncurses5-dev and libusb-1.0-0-dev to compile and work properly.
