OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

[Skitzzo]

Let me start off by saying that I'm quite new to mining and am definitely not experienced with git or using the Terminal. I'm on a mac and used the tutorial on nwoolls.com to get started. I am using 4 USB Asic Block Eruptors and until this evening was having no problems at all.

I came home tonight and noticed I wasn't generating any shares and started trying to figure out what was wrong. I ended up trying to update CGminer but given my lack of experience, managed to muck that (as well as Homebrew) up, and had to start over. Unfortunately, the tutorial at nwoolls.com no longer seems to work for me.

I stumbled across this thread and downloaded Karin's miner files and that will get CGminer 3.3.4 running but I am getting a TON of the following two messages:

AMU1: TIMEOUT GetResults took 1711ms but was 100ms
USB: AMU1 read1 buffering 4 extra bytes

It also seems to only be recognizing 3 of my 4 miners.

Did I screw something up? Did one of my miners go bad? Or...? Again, I am sorry if this is too noob of a question but I'd be happy to send a small tip to anyone that can help me figure this out.

Thanks!

Woo! I found Kano's guide on setting up Arch Linux on RPi, Helped me get my Linux on my Tablet working! Bad news is it keeps spewing out

Code:

AMU0: Comms error (werr=-7 amt=0)

Any clue what the heck is wrong?

For the brave (and very few) BFL SC single owners out there that wish to flash your devices to try and get the last bit of hashrate out of them, I have uploaded 3 different compiled firmwares here:

http://ck.kolivas.org/apps/cgminer/BitForce_SC/BitForce_SC_1.2.6ck.zip

They all try to enable extra engines than the default firmware does, but in addition I have made 3 different speed ones available, they're tagged 7,8 and 9.

I suggest you start with the 7 first, and if your HW error% rate is less than 2%, try the next one up. I have two singles and one worked best with the 7 version while the other with the 9, so each device will be different.

Remember to put the pins right when connecting your AVR dragon to flash it, and note the different device that Amtel Studio tells you the single is (compared to the Jalapeno) and change your settings accordingly.

If you don't know what the hell I'm talking about, then just ignore this message, since it assumes lots of prior knowledge about flashing the Jalapeno.

This directly relates to the whole libusb monologue I've been having in here over the last month
That specifically means your libusb on your mac is bugged - the timeout option when doing I/O isn't working
The README says how to build with a working libusb and it works on Linux and Windows - no idea about a Mac ...
Tell whoever Karin is to read the README ...

Possibly the same as my post above ... ?

Edit: there's a test program in my cgminer-binaries git to tell you if that's the problem

Thank you. Any reason to take my jalapenos from 5 to .6?

Honestly I don't know if that firmware applies to Jalapeños, and I've never tried, but if it does, then trying out the various speeds per device would be wortwhile.

So compile a working usblib and recompile cgminer with it as per the readme at line 112? I was hoping I wouldn't need too but I'll do it.

Ah ok. Lastly little single?

I've only tried it on singles and the code looks like it's for that only, so again, I don't know.

I tried this with nogpu.exe, but not working.

You are using a VERY old version of cgminer ... get the current one.

Yes - 3.1.1 working with

Code:

cgminer-nogpu.exe -o eu-stratum.btcguild.com:3333 -u user -p pass --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S \\.\COM3 -S \\.\COM4

With 3.3.4 not working.

 May I ask why you don't use the normal cgminer binary with the -G flag ?

Different drivers need to be installed with zadig between 3.1.1 and 3.3.4.  What works in 3.1.1 will not work with 3.3.4.

[OtaconEmmerich]

compiling the working libusb didn't help at all, but I think it's my USB Hub is what the issue is. My BE's work if I directly plug them into the OTG cable. The question is WHY is my USB Hub effecting the hashing? It works perfectly fine on my PC. It's a Digital Innovations 7 Port 2.0 Hub, maybe this has something to do with the Serial USB chips using USB 1.1?

Not enough power?

Because if you use standard CGMiner.exe and your only ASIC mining it will require OpenCL SDK/Runtime to be installed to run.  If you use CGMiner-nogpu.exe then you don't need any AMD software at all.

3.3.4 being the much simpler route if your setting up a new system.

If your already committed to the serial drivers then that may not be the case.

The Hub works perfectly fine on the PC, It spits out errors even with one BE is connected to the Hub. I'm thinking it's some kinda software issue as I don't have a normal Arch install.

BE draws way more power then most other devices. As I am sure you have read it is far over spec for usb1 and usb2. It might be in spec for usb3. People get around the power issue by wiring the hub in question to a higher current source like a computer PS. Then you just have to worry about the Vias on the board carrying the current without failing.

Good luck.

 Well that makes far too much sense. TIL. Thank you.
