GekkoScience Compac BM1384 Stickminer Official Support Thread

[philipma1957]

So far my biggest issue is going past 2 sticks.  All 3 pc's windows 7 or windows 10 act poorly once I add a third, fourth, or fifth stick.

I can run two sticks as high as  freq 350  I NEED A REALLY GOOD FAN FOR THIS! But they run fine.

If I do 3  or more sticks on the same setup even at freq 175 they start dropping hash.

Not liking this issue.  Has anyone been running 4 or  more sticks with good results.

Has anyone tested to see which is best on RPI Minera or Raspbian running cgminer?  I thought I would get it today, but looks like Tuesday I'm getting a RPI model B.

Just wondering if anyone has tested both.

I haven't run cgminer-gekko without minera, but my guess is that there would be no actual difference (other than usability). The mining itself is handled by cgminer.

Minera is just the management application. It makes it easier to change the config (if you like GUI interfaces over config files) and it provides a nice summary of statistics in a nice looking web GUI. It also takes care of things like starting the miner at boot, auto starting if it crashes, and stuff like that.

But under the hood it's still just cgminer running under screen.

One of them needs a little more voltage
I just got it up and running Minera modified edition on raspberry Pi 2 running great with 10 Sticks Clocked at 256.25 Screen Shots of setup below

You can run minera on all editions of the Pi I tested the cgminer-gekko on a Mac runnign windows 7 Vitual Machine worked great today I built out a fresh pi image on a Pi 2 and its running more stable also using a much beefier USB hub with 60AMP of 5V power

[mindtrip]

Novak can you provide a diagram showing the voltage adjustment position in relation to voltage I use the flat surface as a guide and with it directly flush with USB port I have been able to get to 250 mhz or so no HW errors I dont have a volt meter handy to test what voltage that brings me up to

Thank you. I posted a question for you on another thread do you know if I can run older U2's in the same instance of cgminer or can I only stick to the compacs id like to fill the rest of the hub with my older U2's and ahve only 1 pi 2 running them all

[novak@gekkoscience]

Trying CGMiner now. Getting a "Failed to initiate device" error. It recognizes the devices.

Using ./cgminer -o stratum+tcp://peercoin.ecoining.com:3336/ -u blackbird.2 -p 12345 --compac-freq 150

I would like to help, but I have not seen that error specifically.  Can I get a little more info about your setup?  What OS, How are you powering, did you rebuild cgminer,etc?  Maybe get a little more cgminer output?

I posted a question for you on another thread do you know if I can run older U2's in the same instance of cgminer or can I only stick to the compacs id like to fill the rest of the hub with my older U2's and ahve only 1 pi 2 running them all

I don't know if they will detect correctly, as the icarus driver specifically can detect anything with approximately the correct chips.  You can try, you'd need top build with --enable-icarus and --enable-gekko.

Novak can you provide a diagram showing the voltage adjustment position in relation to voltage I use the flat surface as a guide and with it directly flush with USB port I have been able to get to 250 mhz or so no HW errors I dont have a volt meter handy to test what voltage that brings me up to

mindtrip, are you using my Minera mod? If so, I didn't build it with --enable-icarus. I only used --enable-gekko, because originally I was building this for me and I only have sticks, not U2's.

That said, it should be easy to rebuild cgminer and add Icarus support. Here's what the steps would be after ssh'ing in as the "minera" user:

Code:

cp /var/www/minera/minera-bin/custom/cgminer-gekko /var/www/minera/minera-bin/custom/cgminer-gekko_saved
cd /var/www/minera/minera-bin/src/cgminer-gekko
./configure --enable-icarus --enable-gekko
make
sudo make install
cp cgminer ../../custom/cgminer-gekko

Hopefully you won't have to do a "make clean". I suspect that since you'll be changing the config above that cleaning probably won't be necessary.

After the above, you should be able to restart the miner from minera, and it will be running the updated cgminer with icarus and gekko support.

Of course enabling U2 support doesn't guarantee that it will work. But at least you'd be able to test at this point.

If something goes wrong, you'll have a backup of the original mod cgminer binary (the cgminer-gekko_saved created in the first step).

Oh, oh. I tried to build with icarus and gekko support (following my own recipe above) and I got a compile error:

Novak, could this be a copy/paste issue where a variable got reused without being renamed?

Does cgminer-gekko come with xnsub for nicehash or do I need to patch it in myself?

Thank you novak!  I was afraid of turning it much on my own.  This explains a lot.

Has anyone used the RPI 1 B with it and RPI 2? I was wondering if there is any noticeable difference for this with the RPI 2 that is worth the upgrade cost of getting another PI.  Was not sure if worth buying one or not.

So flat edge flush with bottom would be what voltage about?

It would depend which way you turned it.   Did you turn right or left and how much?  Could be .8 or .55 depending on that or between.

Novak, could this be a copy/paste issue where a variable got reused without being renamed?

Turns out there were a couple of duplicate lines of code. I removed them and it compiles now.

Here's what the relevant section of cgminer.c code looks like without the duplicate lines:

Code:

#ifdef USE_ICARUS
char *opt_icarus_options = NULL;
char *opt_icarus_timing = NULL;
float opt_anu_freq = 250;
float opt_au3_freq = 225;
int opt_au3_volt = 775;
float opt_rock_freq = 270;
#endif
#ifdef USE_GEKKO
char *opt_gekko_options = NULL;
char *opt_gekko_timing = NULL;
float opt_compac_freq = 125;
#endif
bool opt_worktime;

EDIT: Unfortunately there are more build errors in usbutils.c. They're probably the same kind of thing. I'll take a look, but I might run out of time before I have to go to a dentist appointment.

Novak, since you're the author of these changes maybe it makes sense for you to try building with both icarus and gekko on. I'm sure you'll see the same compile problems. They should be simple to resolve.

If this is Minera do you mind uploading a image if you got it to work with both icarus and gekko?   Currently i'm using icarus, but eventually once I get production one it would be great to plug in and it uses compac.

I can try. But first we need to be able to build with both features on. I'm still running into compile problems (see my edits above).

After that, if I have a working build, it will be a lot easier for me to post just the fixed binary. Maybe you, or mindtrip, could test with that (it's simple to install the updated binary to an existing installed minera mod). I can't test because I don't have a U2.

If that works, then I can take the time to re-image and re-post the updated minera mod.

Also, is there any other mining hardware likely to be used with the minera cgminer-gekko mod that are off by default? I'd rather turn them all on now rather than keep re-posting updates.

That one might be on me for failing to gut all the icarus related stuff out of compac drivers.  I've been collecting some small things that need to be repaired and I'll probably post an updated version soon.  As far as your fix where you deleted the duplicate lines that's fine unless you don't build with --enable-icarus, because there are still apparently references to opt_anu_freq in driver-gekko.c.  As I said, I have them cleaned up in my current working version and should have it out for you guys soon.  I'll try to test with the u2 as well.

Does cgminer-gekko come with xnsub for nicehash or do I need to patch it in myself?

It's the same as stock 4.9.2, so, no.

So flat edge flush with bottom would be what voltage about?

It would depend which way you turned it.   Did you turn right or left and how much?  Could be .8 or .55 depending on that or between.

Not sure what you mean but no, it's always the same voltage.  About 0.68V.

Thanks for looking into this. There are other compile problems with usbutils.c, which I've just worked through. Now I'm seeing problems with driver-gekko.c.

Unfortunately I'm out of time for the next few hours. So I won't be able to poke at this anymore.

But none of these are difficult problems. Looks like it's just some clean up to dis-entangle your gekko implementation from the same named code and variables for icarus.

If you get a clean build before I do, I'd be happy to take your source updates and rebuild for the Pi.
