Posting a link to an image file on your desktop doesn't work here.

I know it wasn't the help you were looking for, but it's help.

Same driver. I've updated our Windows installer for those interested in a quick and easy method of deploying your New R-boxes. The installer includes zadig and a Windows build of Rockminer's latest customized cgminer.

Download Windows Installation Package

I am running them on MinePeon on a Raspberry Pi using BFG miner and getting about 110 gh/s.
I will have a review up soon with more details.

Thanks!  Are you running it with BFG or CGminer?  I'm wondering if it works with the same driver as the previous generation did...

B

It is fairly quiet.  Not quite as quiet at the R-Box but still nice and low.

Does anyone have one of the new R-Box 100GHs up and running?  How is the noise level compared to the first R-Box?

B

Yes they are and will be back on soon.
 

is rockie alive?
josh maybe?

Unfortunately I believe you are correct.  I've been looking at tubes for some time.  The controller has an incorrect stratum implementation and as such is unable to communicate with many pools.  One problem we were able to figure out, it returns an extranonce2 of the incorrect length, but there is another issue where it sends back something else wrong and does not wind up with a valid header, resulting in some pools giving an h-not-zero or similar error.  We've been using the latest build of ckproxy, which contains the extranonce2 fix and works with ozcoin (and some others).  At least it seems to crash less than once an hour, as some have noted of bfgminer.  bfgminer does have the advantage of working with more pools, however, as whatever the h-not-zero error is, bfgminer does not seem to get it.  If someone were to workout what was going on, it's possible that a better proxy could be made, but let's face it, no one really wants to use a proxy.

This is something I'd REALLY like to pull off, but I'm not certain how difficult it will be.  R-T-B noted that the source for cgminer contains a reference to the rockminer T1, but looking at the code I have come to be unsure if it really means the T1.  First, it says in the comments that the rockminer T1 is the rocketbox and it appears that it has 12 chips. Perhaps the variable was just chosen very poorly before the T1 was anything- there's also a T2 for some reason.  Also it has limits on the baudrate which are substantially beneath the required 460800 baud required for the X24.

Most of the UART communication info on the X24 board I'm pulling from here:
https://github.com/blockerupter/avr_hbc

I have a device called a buspirate, which, apart from being useful for jokes about how it sounds a lot like buttpirate, is also useful for bidirectional USB-UART communication.  I was able to sniff the serial traffic coming from either direction, but I can't sniff both at once with the thing, so I've got no idea what the timings are and I failed to successfully spoof the board into believing it is hooked into a controller.  I need to build a better UART sniffer, probably chuck an AVR in there and read out of both RX and TX at the same time.

We have all the documentation on that github so I'd like to think we could successfully replicate a driver to run on the raspi, it's just going to be a question of effort.  I was really hoping friedcat would release fixed firmware but it seems not, at least he has carefully avoided saying anything to indicate that he would.

I wish it was a dns issue..but from reading other threads for asicminer tube https://bitcointalk.org/index.php?topic=735728.200 ..its looks more
like buggy software connecting to the pools and errors out and it won't hash.

With some testing these are some of the pools that worked for me which might be useful for other newbies like me.

btcguild
stratum-lb-usa48.btcguild.com or 50.31.189.48
Bitcoin Affiliate Network
mining.bitcoinaffiliatenetwork.com , east1.bitcoindigger.com , west1.bitcoindigger.com
ghash
according to this thread https://bitcointalksearch.org/topic/asicminer-tube-owners-thread-768500 by WBF1 and the asicminer tube owners
this other pool works
mmpool, slush pool

Pools that worked with bfgminer proxy with this setting
bfgminer.exe --stratum-port 3334 -o pool url:3334 -u userid  -p password --set-device PXY:diff=512
eligius,bitsolo,f2pool but unfortunately not too stable...bfgminer would error out from 1-3 hrs and the miner looks like its connected but it wont hash.

Pools/leasing service that I can't connect to
p2pool,westhash/nicehash,miningrigrental,betarigs

Anyway we can connect this to a rasp pi like btcgarden amv1x2? Looking for alternatives here...

btcguild worked for me before. make sure you take away the "stratum+tcp://" bit. So:

stratum+tcp://stratum.btcguild.com

I'm at slush's pool and its working. DNS issue? Maybe?

That USB to UART adapter is using the Silicon Labs CP2102 chip?
   CGMiner utilizes Zadig drivers and BFGMiner uses the SiliconLabs driver, in the past if you tried to switch miner software you had to completely remove Zadig before running BFG Miner.
  The Icarus devices in the past also required you to unplug then hot plug them back in to get the miner software to recognize and launch for work from stratum.

Unfortunately yes.  It's basically the same hardware inside, thus the same limitations.

Some people are working on a cgminer build that supports this with a usb adapter, but it's a ways off.

Is there a list of pools that are currently working with the Rockminer T1?

I'm having issues with the block erupter not hashing on pools aside for ghash..not even stratum.btcguild.com works only with the 50.31.149.57 ip address. Is the T1 gonna be limited to the same pool selection as Asicminer Tube?

The stratum failure is unrelated, it's because I tried to connect on port 80 like a dumbass...  Not sure why it's not finding it really.  It must be driver differences.

That is interesting.  I would like to think that this means you're on the brink of getting it.  At the least, it looks like you have serial comms.  Maybe look for that error in cgminer? (Initiate stratum failed)  Let me know if you get anything more.

Now this is interesting:

Output log of cgminer --debug, using a baud as indicated (--icarus-options 406800:1:1?)

Thanks again Novak, I will try those settings in a couple of hours and report back.

by the way, cgminer source code has this set of lines in the drive-icarus.c, which I find VERY interesting:

#define MAX_TRIES 4
#define RM_CMD_MASK 0x0F
#define RM_STATUS_MASK 0xF0
#define RM_CHIP_MASK 0x3F
#define RM_PRODUCT_MASK 0xC0
#define RM_PRODUCT_RBOX 0x00
#define RM_PRODUCT_T1 0x40
#define RM_PRODUCT_T2 0x80
#define RM_PRODUCT_TEST 0xC0

Note the bold.

The Rockminer "T1" is electrically identically to the ASICMiner Tube.  Is there any chance it actually supports the T1 in it's source code, and thus the ASICMiner tube as well?

When I find out, I will let you know...
