For what it's worth it's been my experience that BTCGuild has been the most stable with the least number of rejects of many pools I've tried (by a wide margin too such that it's even worth the fee). You may want to test pointing your hashing there and see if it works better.

oh, that pool is very unstable here. you know i'm in the Great Fire Wall. now i'm using ABCpool.co

I expect all new products to have problems
and brought icarus to test fpga mining and the product
and 1 X 380 mh/s miner locking up is not a problem at all - so take your time to fix it

in next 6 months I want to get rid of my all GPU's based miners
and buy about 200 fpga based miners

Oh. Weird. I figured since I was in Thailand it ought to be even more stable for others. I think our data mostly goes thru Singapore so maybe some other routes are worse. (We have a crazy number of hops before it even leaves Thailand.)

If someone wants to test the miner I'm currently working on, I prepared a litte prerelease for testing purposes. I'm using it to mine since about 12 hours now. PM me and I send you a copy (I don't currently have any hosting ready where I could put the file). The miner is written in java and should not be affected to much by a bad network connection. Long polling is not yet supported but it's the next thing on my list. I probably release the miner as open source when it's ready. Feedback is highly welcome Smiley.

Hm not sure if that works. Github is free for open source only, and I'm not ready yet to fully release it.

good work!

Try adding http:// to the url, it doesn't recognize it as an url. Currently there is no validation of input parameters, that code part was added in a hurry to be able to share a first usable edition. But still, you found the first bug, it should abort on MalformedURLException because further tries won't ever succeed. Default behaviour is to try for ever to make sure it starts working again after networking problems occured.
Multiple boards with one miner instance and LP are on the todo list Smiley.
I'm not sure about scanning the ports though, I wouldn't want a miner to automatically write to all my serial connections. But something like a startup flag would probably be fine.

Looks like I'm gonna jump on the FPGA bandwagon too. Just placed my first order today. Hope everything goes smooth.

Question for ngzhang (apologies if it's been asked before): Can the dev kits be ordered separately? Or they must be bundled with a FPGA board?

i just add a "http://" but looks like no use... maybe deepbit is a little different? BTW, i'm using windows7 64bit.

an additional beg: is it possible to add a valid nonce offset parameter to the program as a debug function? it means add or subtract a constant value to the calculated nonce. this will help me a lot on the debug flow.

thankyou~

i replayed your mail, and certainly , the Dev kit can order separately (with the same price).

...

Hm seems I have to look into that deeper. Did the error message change after adding 'http://'?
About the nonce offset, I can add this. Right now I inverse the nonce as soon as I receive it (the displayed value in the log/console is also already inverted). Does the offset have to be added to the inverted nonce or to the nonce as it's received?.

i must say this stuff is stable. during a bad network condition, no fault appears. the stale rate is about 3%.


now the nonce is transmit from high to low byte. if you need a byte inverse after received them, i think the off-set value must be add to the inverted nonce.

Everybody

May i please direct your attention to the following thread:

             Modular Python Bitcoin Miner
https://bitcointalk.org/index.php?topic=62823.0

It is a new python only FPGA board hostprogram.
It therefore runs on ethery plattform with python 2.6+ (also ARM etc)

It currently includes a module for the x6500 board.

I would like to advertise the creation of a worker module for the icarus board.
It would certainly benefit all participants.

Im not good at programming high level languages.
So maybe somebody else is willing to do so ?

If you change the serial protocol a bit, it might work with the SimpleRS232 interface that MPBM provides. This would also fix some other flaws that I've spotted in the interface you're currently using.
Alternatively the SimpleRS232 interface module could be adapted to fit the current bitstream, but I'd really go for the other way round.

Isn't the existing mining software python only? What would prevent it from running on ARM.

Has anyone tried running Icarus off of a Linux router or other such ARM device?

V1 bitstream used TCL script as mining software.
But the protocol is so simple that any programmer can create/modify other miner in less than a day.

Changing the FPGA firmware is much mode difficult and time-consuming than just modifying the mining software.
