I have it running in windows 7 with a compac and a twopac.

I wrote multiple start bats.

I have this as a working bat

but it gives stock freq as it should since no attempt was made to change stock of 150 for 1 chip and stock of 100 for 2 chip

...

this bat crashes I tried to add freq 200 it was first shot but what must be done for correct setting of 200

...

Try:
--gekko-compac-freq 200 --gekko-2pac-freq 150

Instead of:
--compac-freq

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

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.

Added. Thanks for spotting that.

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

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.

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.

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 Cheesy

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

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.

My AR-15 ID's itself as a toaster. Want breakfast?

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 =)

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

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://bitcointalksearch.org/topic/m.17596575

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

Quote

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

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

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

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. Sad

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.
