Just released my java miner for the Icarus FPGA board (see https://bitcointalk.org/index.php?topic=51371.0).

Features: If you have a Icarus board, it'll mine bitcoins for you Grin. This and long polling.

This is the first thing I release as open source, so feedback is highly welcome Smiley. The miner should run on win, linux and mac.

Download: https://sourceforge.net/projects/rg7miner/

It just came to my mind that the recent fix for abcpool might not completely fix the LP problem (about 50% of LP requests might not work correctly). I'll test and release a fix for it today (I'm in UTC+1).

Just uploaded the new version. It accepts an additional parameter to set a timeout for the long polling request (start without parameters to show all possible parameters).
Please set it to 59 when mining on abcpool. Additionally, you'll see a warning "RPC json response is invalid: missing ID element." on every long polling response. The ID element is required by the specs but the miner doesn't use it, so you can safely ignore the message, there isn't any limitation in functionality.

testing...

i think this is a good simple miner, is the best choice for a single board user.

I have just used your miner to confirm my newly received Icarus are working fine. Took me less than 5 minutes to get it up and running on Windows 7, good work.

I am now running multiple instances, adding one by one. I guess I have to go buy a decent USB hub soon.

COM3 to COM7 up and running!

I like the fact that it writes timestamped logfiles, so I have now 5 log files and can head out for a few hours and have a look when I come back later.

Got this on unit no. 3 once but still seems to work fine:

[2012-02-28 17:36:48,341] [port=COM5]: HW error. Received nonce e8830080 doesn't produce a valid hash.

The miner checks every result it receives from the board before submitting back to the pool. Some results are invalid which seems to be normal, all my boards produce invalid results but on a very low rate (see the invalid value in the miner output).

I am still running my 5 instances of RG7Miner. I get the HW Error about the nonce that didn't produce a valid hash once in a while, that's clear now. But overnight had had two units fail with (almost) endless loop of HW Errors of this type. The strange thing is that after a while there was on single valid one again, then again lots of errors, then a single valid one again, etc...

Restarting the miner (Ctrl-C, up, enter) gets them going again. Happened a couple of times now. Possibly always on the same 2 Icarus units, but I am not sure yet it's not even been 24h (I have three instances running at 604 minutes now).

What happens if there are new blocks detected via LP or block monitor? Is there just no log output or is it currently not implemented?

Very weird bug, I never had this one, thx for your log. I'm going to look into this.

About the long polling, there currently is no output if long polling requests return with new work (I change this in the next version). If the value before valid shares is "LP" (upper case), lp is enabled. It will show "lp" if lp is disabled.

What is block monitor?

I have no idea, but I just saw that ZTEX BTCMiner sometimes shows "New block detected by block monitor" in the logs.

He may have a block monitor running in the background that detects new blocks.

I have now moved my 5 Icarus to Modular Python Bitcoin Miner since I finally got it to work. It has multi-board support.

I'm using your miner for my test board. Works well so far. I hope you continue your development.

Just a hint for stupid users like me, the format is <user> <pass> <url> <portName> but port means COM3 or something else not the port of the pool  Cheesy

I am still running my 5 instances of RG7Miner. I get the HW Error about the nonce that didn't produce a valid hash once in a while, that's clear now. But overnight had had two units fail with (almost) endless loop of HW Errors of this type. The strange thing is that after a while there was on single valid one again, then again lots of errors, then a single valid one again, etc...

Restarting the miner (Ctrl-C, up, enter) gets them going again. Happened a couple of times now. Possibly always on the same 2 Icarus units, but I am not sure yet it's not even been 24h (I have three instances running at 604 minutes now).

Get this HW Errors too once in a while. Had it about 3 times in 72 hours.

I am using windows7 64 bit, CPU is Intel i3 @ 3 GHz.
I copied rxtxserial.dll from the winx64 directory and started rg7miner with following error message:

Why it tries to load AMD 64-bit .dll Huh There is no AMD processor...

Any ideas?

Try "C:\RG7Miner>C:\Java\jre6\bin\java -jar rg7miner.jar beach.1 x http://123.123.123.123:8332 COM1" (example port) !

Thanks for that hint! Smiley
How I can figure out which COM port to use?
What additional software I need to address COM ports over USB an a Ubuntu 10.4 Linux?

Cu,

I have now moved my 5 Icarus to Modular Python Bitcoin Miner since I finally got it to work. It has multi-board support.

Could you provide some help for other Icarus board users? Smiley
Which software do you use to convert COM port to USB?
I have 15 Icarus boards running now, but I am unable to use them so far.
rg7miner, cgminer and MPBM can not access the Icarus boards even when I plug them into the USB port of the computer they are recognized from Linux as USB0-USB9...?

Any hints?

Cu,

Hi Eckmar. You can find the link to the drivers on the first page (initial post from zhang) in the ngzhang fpga miner thread.

Those of you who have this working...

Are you using 32-bit or 64-bit Java. Also, are you on Java 6 or Java 7? Lastly, where are you copying the rxtxSerial.dll files?

I use 32 bit Java 6, just copy the rxtxSerial.dll for your system to the same location as the java file.
