Hello,
I want to run ktest on a RasPi.
Can some one tell me how to do this ?
Thanks!


Edit: I used git to clone the Klondike directory so I should have all the files I think.
There is a directory called utils in there excitable code called ktest.
When I try to execute it I get the message below.
File "./ktest:, line 22, in<module>
  import usb
Import Error : No module name usb.

Any help is approached.

Edit2:
Got this working by doing this
git clone http://github.com/walac/pyusb
cd pyusb
sudo python setup.py install

Now ktest runs. "I"command results in: Version:10, ProductID:K16, Serial#:deadbeef

You need to install the pyusb Python Module.

If pip is installed, then pip install pyusb should suffice.

However BKK mentioned in this post https://bitcointalk.org/index.php?topic=190731.msg2731881;topicseen#msg2731881  that if your Distro has an old version you may want to compile the usb module manually.

Another problem I  noticed, is that when I setup cgminer with the API options for K16, cgminer would have a Segmentation Fault when trying to access the API to get stats.


Has anyone else had SegFaults when trying to access the K16 API ?

Hey Guys. Im trying to do some testing with ktest but don't seem to get any desirable results. At one point, I got the "W" command to work, but it resulted in a BAD response , which I would think should be accepted, if Im reading the code right using Below Var:

Code:
Work =   ["4375c3b7a27cc936f295a6140358e965319322e7cfd11e137df42ea60864a675", "218d522051d547d51a00c94e", "b2cc9f74", "accept"]

Now, I run W command (aftere restarting ktest) and I get no response at all!

Trying to find out if theres a proper method to using ktest or if there could be something wrong with the K16.

I added a small debug output in sendcmd under the dev.write line:
Code:
dev.write(0x01, cmd + chr(addr) + data, 0, 500)
          print "tried %s %s %s" % (cmd,addr,data)

Code:
python ktest

Is there something I am missing here, or something else I should be checking out?

thanks


It is most likely a hardware bug in the circuit. During our testing we realized that the Dual NOR gates used in the design are too fast, and there needs to be some propagation delay. Using a cheap NOR gate chip from Fry's did the trick. We are still trying to see if this can be fixed in the firmware.

Maybe you may also want to try to use a bigger capacitor for the phase shifter in front of the NOR gate. A circuit should not depend on the propagation delays or fabrication tolerances of logic gates. I also tried to use the internal comparator of the PIC as a NOR gate, which is even better since it has some clock synchronization register. But it has shown that the comparator is not fast enough...

Has anyone else had SegFaults when trying to access the K16 API ?

kosta

Yes I just compiled and got a segmentation fault. I was assuming that it was due to a graphics driver issue, because my cgminer (with gpu) does the same thing, while my cgminer-nogpu does not do this when I compile it under Linux Mint 14.

How do you get cgminer to compile with no gpu support, but with klondike support and icarus support?

I wanna test Klondike compiled version actually runs, but I don't have a Klondike, so I want to compile it for icarus as well.

I can't find the flags list anywhere (having a mental moment)...

Hi guys,

I've got cgminer compiled and it's working quite good on x64 and RPi. API working as well.

Things I've done:
Cloned repo here https://github.com/bkkcoins/cgminer-klondike
Then in the folder:
./automake.sh
./configure --disable-opencl --disable-adl --enable-klondike
make

Just one problem - when I connect more than one K16, it wont start, just freezes where it says CGMiner version ...
With one it's hashing OK. Anyone had success with this?

Thanks.

Do you get any debug output or any error? How many K16 are you trying to connect and by which method are you connecting them?

Ok Zipiju thanks a lot !!!

I used your suggestion (but without the ./automake.sh cuz it was not working) and added the following

./configure --disable-opencl --disable-adl --enable-klondike --enable-icarus
make

it compiles and runs just fine.

I wanted icarus devices to test USB functionality, and I happen to have 3 USB block erupters handy...so...

When no USB erupters are plugged in, it does nothing.

When I plug in 1 usb erupter directly into the computer, it says "USB init open device failed, err -3, you dont have priviledge to access - AMU device 2:8"

Then I plug in the second one, and it detects it and says "USB init open device failed, err -3, you dont have priviledge to access - AMU device 2:9"

Then I plug in the 3rd one, and it detects it and says ""USB init open device failed, err -3, you dont have priviledge to access - AMU device 2:10"

So, the USB detection is working, that's what I'm guessing anyway. Whatever version of the usb library is working, and it seems to be detecting, at least, it detects Icarus devices.

I think that's good news.

Weird, so I've created a strange Klondike, Icarus hybrid. My guess is since the usb detection is working, it should detect Klondike's as well....

I'm connected to my pool but I usually have configuration problems with USB Block erupters and CGminer (I use BFG miner under windows to run my USB block erupters)... Gonna work on getting them working Under linux just for kicks.

If you have any USB erupters or can borrow one, try it. I am not a Unix expert by any stretch of the imagination...

Not sure which boards you have but are you running as Root? I thought I read some problem with certain boards that if you did not run as root, or apply their workaround, you could get that error.


IF your not running as root, Try doing so to see if it works. If it does, go search the forums here to find out what the workaround would be, as you should *never* run services like these with root access.

Already tried using bigger capacitor. Does not work. The only work around we have found is using a slower gate, so far.

You guys are godly ! At least, I think so.

Ok so I did:

 sudo groupadd plugdev (wasn't necessary, plugdev was already installed).

then

sudo usermod -G plugdev -a `whoami`

then

 sudo cp 01-cgminer.rules /etc/udev/rules.d/

Then rebooted.

3 block erupter USB detected, but it's hashing really slow, like 100 Mh/s each.

 Doesn't really matter at this point for the speed, I just wanted to see if the Klondike-Icarus hybrid compile would detect and hash using some kind of USB units.

I'll try again later with a pure Icarus compile, and see if there is any difference. But, this may be some kind of progress, I hope.

Did I mention you are godly? (I'm learning unix on the fly here....)

Nope, even with -D option, no output at all. I'm connecting 2 K16.
I just connect them to the usb, see them successfully enumerated in dmesg, then run CGM and it does nothing, just stays at the point where it says CGMiner version 3.3.1.
With one it's OK.
Also, each board have different serial number.

I'm sorry to tell you, but you're wrong.
I'm using v0.3.1 board with bigger cap (currently about 260pF) and it's hashing quite well.
Without it, the clock signal is not delayed enough - just about 5ns and bad nonces are returned.
BTW terrahash, what modifications did you made to the 4 chip firmware to hash with all 16 chips?

Sigh, I spent a reasonable amount of time over more than a month resolving this (and commenting about it in the cgminer thread)
It's a libusb bug
(ckolivas also recently found another one ... in libusb ... and change the usbutils.c to work around it)

The 100MH/s simply means the libusb you are using is no good.
It's timeouts don't work

You really do need to use current cgminer ... not an old version of it.

Or ... the explanation I put in the README before ckolivas finally added the working libusb source to the cgminer source rather than linking against a system installed version.
