GekkoScience Compac BM1384 Stickminer Official Support Thread

[sidehack]

I'm hopeless at this, aren't I?

The short and not very polite answer is, pretty much. But the stick is meant as a learning tool; you're now being forced to learn some new things.

Please note a couple posts up where it's said:

The tar.bz file is for building it yourself (on raspi usually). You would need the zip file on the first page of the thread. Then do as sidehack has said and copy the zlib.dll file from the standard cgminer (in the mining software section of the forum). Copy that over to the gekko version, run zadig to change the drivers on the cp2102 uart controller to winusb, then run the bat file.

This will solve about half your problems.

The other half are the "./" at the start of your command line in the batch file - that's a linux-specific thing (telling the command prompt to look for the program in the current folder instead of searching system-default paths) and isn't necessary for Windows.

run your bat then unplug and plug in your usb sometimes that helps

Doesn't work. Since the command prompt just turns off in less than a second after i turn it on.

post your bat file in here again i suspect something is wrong in the bat file

ok seems like you posted something earlier

./cgminer -o stratum+tcp://us-east.stratum.bitcoin.cz:3333 -u AgentRuan.worker1 -p x --compac-freq 150

change that to

cgminer.exe -o stratum+tcp://us-east.stratum.bitcoin.cz:3333 -u AgentRuan.worker1 -p x --compac-freq 150

[AgentRuan]

Figured it out... I used to be a Linux user... so... I think you know what happened. I added an extra "./" to the .bat file...
It now works perfectly.
Thank you all so much for the help! I truly appreciate it!
Guess I'm not completely hopeless after all xD

[AgentRuan]

Hmmm... It's working now... sort of... But what exactly does it mean when it says "Stratum from Pool 0 requested work restart?"
My thing isn't quite mining. It's just... Saying that...
Does mining start after a while? Should i take out my usb and plug it in until it does something else?

[gt_addict]

On the cgminer screen you should see "compac 10000~~~" (~ is another number, basically the stick identifier). Next that you should see the hashrate in GHs. If it shows zero or an "m" after the number then unplug it while cgminer is running and plug it in again. It will say "hotplug compac" it should then start hashing, if not unplug and replug again. Sometimes it can take a few attempts.

[AgentRuan]

Now it's being weird again. Command prompt opens for a second after i open up the .bat file and then, the command prompt disappears. I took a screenshot of it and it says cgminer.exe: --compac-freq: unrecognized option.

I have no clue why...

[sidehack]

If compac-freq is an unrecognized option or the stick enumerates as an AU3, you're not actually using cgminer-gekko. I'm assuming you paid some attention to my last post?

Also, one good thing to do when you have a problem is search within this thread. It's been around for a year and it's over a hundred pages long so it's very very likely that your problems have already been seen and resolved. Multiple times.

Oh. whoops. That last one didn't post from  awhile ago. The thing currently works great! I'm not sure why that took so long to post.
Thank you very much for the help though!

Just a shoutout and hat tip to SideHack - Still running strong!  Obliged!

edit..solved.

Hi
i m new french miner
i ordered 2 stick on bitshopper but i can't go more 160mhz. hashage don't start after this limit
i use a lab power (30v 5A max)
i had to push the usb voltage to 8.5V ! to run at 350mhz
i see a difference about a chiphttp://Tous dans C:\Users\Cc\Desktop\Nouveau dossier\20160716_103958

0250000

IS IT NORMAL ?

this is a sales thread. you should post here instead, more people will see it:

https://bitcointalk.org/index.php?topic=1173963.0

read the 1st couple pages, lots of troubleshooting info there.

your problem might just be the voltage pot needs adjusting.

Sorry
thanks
but i ve already play with pot a very long time !
new chip or new order coming soon ?

Was that before or after you destroyed the buck circuit by feeding the 6V-rated parts with 8.5V?

Also, this is not a tech support thread. If you have questions, take them to the tech support thread.

it was before destroy 1 of Two
i think there is a problem with nomenclatur of bitshopper version
there is a different chip on their board for clock ii think
your model is metal and their model plastic with some différents resistor

ps:

sidehack it s an honor to talk with THE MASTER !

[sidehack]

Shouldn't be an honor. I'm just some dude on the internet.

Also, if you're looking at the oscillator, it's different because the part I originally used on the first batch went out of stock. I provided bitshopper with a different compatible part number, and then started using it myself on later batches. It's a standard 25MHz 1.8V oscillator and has no bearing on your problem.

Most questions that aren't a result of dead or damaged hardware are addressed in the first post of this thread. Like how the potentiometer in the bottom corner of the stick is there to adjust core voltage, which allows you to run a higher frequency. AT NO TIME SHOULD YOU EVER put more than 5.5VDC into the USB jack. Since the buck driver is 5.5V rated and the caps are 6.3V rated, I'm surprised it didn't just explode when you hooked it to 8.5VDC. A regulator's output voltage should not change from a change in input voltage unless something is seriously wrong with the circuit, so that you could get a higher voltage from it with a higher input voltage is a very bad thing. Unless the problem was input power limits from input impedance, where the voltage was bottoming out due to "high" load currents. 350MHz is going to want to pull about 8W which means 5V 1.6A so if your input lines can't handle it you'll see performance issues.

All of this has been addressed, probably repeatedly, in this thread. This thread has been here for a year and is over a hundred pages long. Very few problems by now haven't already been addressed. Do a bit of searching.

And if you try something that destroys the miner, you are doing something very very wrong.

[Cc2Gre]

with only the pot i can't push up than 160 mhz
i used a power lab (5 amp capacity at 5,5v with common masse and without 5V usb) and the current absorbed never exceed 0,75 A on my power...
i try all value of vcore 600 to 800mv

[sidehack]

And you're using the right version of cgminer and the right command line flags?

[Cc2Gre]

of course "gekko" version. very good job for "stock work" at 125mhz

and i have put in a big radiator with 1,8 w/°
i am on multiple forum and the only guy have seriously overclock their model had your's (green) not the black...
or i am very stupid

and please could you answer me of a futur project on 1385 or 1387 ?
If no another board will be sale

[Cc2Gre]

above 150 instable
above 160 170 don't start work

[ZedZedNova]

above 150 instable

To be honest, this sounds like a problem with the USB hub you have the Compac plugged into. The Compac I have is plugged into a powered USB 2.0 hub (it's the only device on the hub), the core voltage is ~0.800mV, and I am able to run the Compac at 325MHz. It's drawing more than the USB spec'd current on the port, but the hub seems to be OK.

There have been some good recommendations for powering your Compac in the last few pages, and if you read through the first few pages of posts in this thread you will find a bunch of recommendations for powered USB hubs that work really well with the Compac miner.

For what it's worth, my Compac is stable, and has been for months. I'm "lottery" mining and participating in the gekkorun.de "race."

cgminer -o stratum+tcp://stratum.antpool.com:3333 -u Cc2Gre.1 -p x --compac-freq 145
cgminer-gekko-win32 on this site with novac driver
and it work very good until 160 mhz for long run

it s not the hub because there is no hub !
and i don't use +5V from the usb port but a stabilized laboratory power with 5A reguled and i never exeed 0,75 A consomation
i know that because the laboratory power display volt and ampere
the masses was joined to avoid floating potential for the stability
