I've got it working now I'm using powered hubs - 20 gridseeds on the one Pi controller.

The crashes have gone away, the problem now is cgminer will stop submitting work after about ten minutes (the miners keep hashing, just no shares submitted for 30mins+).  Killing it and starting a new process doesn't help.  Rebooting the USB hub doesn't help.  Power cycling the miners doesn't help.

Cycling the Pi seems to fix it temporarily until the next time.



I'm running with 12, so it's possible 20 is too much. Might want to also verify that the PSU is still ok by using a multimeter to check 12V rail when cgminer stops submitting shares.

Interestingly I've noticed there is actually a slow decline in work utility until it hits a threshold where it just stops submitting shares at all.  Work utility degradation starts after about 1 minute.

Going to get the multimeter out now.

Doesn't seem to be a power issue, 12v stable.  Will cut down the number of miners and test.

If you don't want to run a bunch of cpuminers, I have posted modified cgminer sources to allow LTC-only mode: https://github.com/dtbartle/cgminer-gc3355. I have this running on a Raspberry Pi with 10 devices.
A big thanks to Andareed from the team of Scripta!
Currently running one Gridseed unit with Scripta and your cgminer: https://litecointalk.org/index.php?topic=9908.msg138195#msg138195
Thanks CH... Does it work with Ras. PI only or I can hook them all up direct to your cgminer via usb hub?
Not sure I got the question right...but what I am using is a Raspberry Pi (with Scripta) and D-link USB Hub where I plugged a gridseed 5 chip miner (I believe you could plug more units...but I have only one...sadly!). Is not my cgminer...is Andareed version!  Wink

Any chance of a Pi image with compiled binary? Smiley

Here's a compiled binary built on raspbian: https://db.tt/UygLkqwd


Hi,

I already had it compiled but downloaded yours nevertheless... I get A:0 R:0 HW:0 WU:0.0/m

THe command line I'm using is:

./cgminet -o: pooladress -u user -p password --griseed-options=freq=850

Even address the baudrate to option but it sill doesn't work.

THe Debug info states the following:
LIBUSB_ERROR_TIMEOUT

It seems that it fails to initialize the GridSeed Miners.

regards,

P.

P.S. - Minerd works ok.

You're missing --scrypt from your cgminer command Smiley

Is there a way to use a regular power supply like this one - http://www.ebay.com/itm/400633139181?var=670187426663&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

Or must I necessarily mess with the wires?

yep that works

Would 5 amps be enough to run in dual mode does anyone know?

https://bitcointalksearch.org/topic/m.5517434

Single mode is 6W 12V .5A max 10W 12V .84A dual mode is 60w 12V 5A max 100W 12V 8.4A so I would say the 7AMP recommendation is SPOT ON for providing max needed power for dual mode!

So if you are running in Scrypt mode we can safely say 1Amp/1,000ma provided will be a standard number and plenty of power for scrypt mode.

Once cablez finalizes a standardized design he will be able to send out a lot of orders pretty quick.

Awesome, thanks so much.

Sorry for the off-top but is there any software used with GRIDSEED (except I guess cgminer for SHA mining) allows for failover pool configuration... I went through all the threads but could not find any reference on that, especially when used with controller board.

Again, sorry if this question has been answered already - could not find it.

Thanks,

Vadim

On my devices the vendor id is the same, so the plugdev file should be universal.
Did you have success on frequencies above 850 MHz?
I noticed you put a voltage section in the configuration, that sets some voltage on gpio5
Is this documented somewhere else ? I looked in the datasheet but couldn't find anything there, neither in the gridseed cgminer version on github.
Where did you find this additional information ?
For now it's running stable on my pi @850MHz for 3 hours and my pi is clocked at default frequency.

I created /etc/udev/rules.d/50-stm32.rules with the following:
SUBSYSTEM=="usb", ATTR{idVendor}=="0483", ATTR{idProduct}=="5740", MODE="0664", GROUP="plugdev"

Then if you add your normal user to the plugdev group you can run cgminer as non-root. You might need to tweak idVendor/idProduct based on the output of lsusb.

Try running this as root via sudo:

Ok, some standard questions to be sure we have the same config:
Do you have your pi running at stock frequency ?
Did you add additional parameters to your modules configuration ?
What is your cmdline.txt

Mine has crashed twice with spurious interrupt errors, killing the miner and taking down the pi alltogether.
I'm running with these options : baud=115200,freq=850,chips=5,modules=1,btc=0
The pi is on a powered usb hub, I've been using these hubs for my pi's for ages and not seen any issues.
The miner is on a dedicated 12V powersupply, that allows 5A, so don't see an issue there neither.
Any suggestions are welcome.

Thanks heaps - is the MHz set as compile time?  Anyway to get 850mhz?  --gridseed-options=baud=115200,freq=850  
still no work utility   d'oh forgot the --scrypt

Also this seems to work OK for 10 miners but over that kernel panics the Pi.

EDIT: Nope crashes with 10 also, tried with two different sets of 10 miners Sad

Also seems that no work is getting submitted and work utility is zero


I pushed a change and updated the binary to add nonce generation per chip. This gives some assurance that you don't have any completely busted chips.

I built your code from github, it is working fine on my pi.
The Accepted shares are off for some reason on the interface.
I also monitor the cgminer with the networking API and there they seem to be correct.
Not sure where this might be hidden in the code , but if I have time later, I might take a look at it.
