Bitparking says 0mh/s

[jago25_98]

The hashrate reported at bitparking.com/(user) is saying zero.

I only have a single USB eruptor. It's saying:

What's going on?

Right... must be something to do with the RaspberryPi... no such errors from the laptop. Perhaps the USB port couldn't handle the heat.... will have to test some more...

edit:

Code:

raspberrypi ~ $ /opt/vc/bin/vcgencmd measure_temp
temp=56.2'C

^ though this is the CPU rathe rthan the ethernet/usb chip which also generates it's own heat. It's possible the heat from the Eruptor conducted through to the Pi and that's effected the Pi usb chip... however it's strange that the fail happened as it did; only slightly...

Next thing to do I suppose will be to try a USB HDD.

[jago25_98]

Yup, USB HDD is dead too.

Let this be a lesson to you folks - if you plug your Eruptor straight into your Pi your'll burn it


shameless hotlink...

meanwhile... on the laptop:

Code:

AMU0: invalid nonce - HW error

I wonder how hot the Eruptor is running and what it's limit is... perhaps a fan is essential...

[jago25_98]

Seems I'm just talking to myself here using this thread like a diary. I was hoping someone might chime in and tell me a way to monitor the temp on the USB Eruptor.

Tried a USB flash drive in the Pi and it works... and the Eruptor works on the laptop (I've no USB powered hub yet to help with testing) which all points to the mips compiled cgminer... but different versions and I still get 4bytes etc and so forth.

I still think I've overstressed the Pi USB ports somehow. It would be good to be able to know that the ports are ok for sure.

update:
Now running on a BeagleBone but need to create the /dev/ entries for /dev/ttyUSB0 or AMU0...

[purelithium]

You NEED a powered hub for the Erupter on a Pi. The Pi doesn't put out enough current from the USB port for it to properly power the device.

[jago25_98]

 The 2nd USB hub I've tried doesn't work (AMU0 errors).

Which hub on ebay (item number) definitely works?

[purelithium]

Here's a thread on he forum: https://bitcointalk.org/index.php?topic=253749.0

I person use the D-link DUB-7 and Vantec 10 port listed in the thread.

Also, check that your username in cgminer and bitparking match.

amu 5 and 2 arnt accepting any shares so there hashrate dosnt get counter try each 1 on its own in a PC usb port on in the hub on the pi 1 at a time. more than likely its a power issue what else is in the hub? each erupter uses 500ma so if its a 3A hub the most you can run is 6 erupter plug anything else in and it will cause erupter to error
