I ordered and received 2 Moonlander 2s from asicpuppy. One of them works fine but the other seems to be dead on arrival. No matter how I connect it to my pc, the miner software will not detect the device. I reached out to asicpuppy support but haven't received any response. Anyone else have experiences with asicpuppy's support that can help? Thanks!

Does it show up at all under your device manager? Does the yellow or red led flash at all when you start up bfgminer?

It does show up under device manager. The D2 led stays on and no other led flashes when bfgminer is on.

Please put

Code:

-D  2>log.txt

at the end of your bat file, and put the log file on pastbin and send it to me (it will be in bfgminer folder named log.txt).

I have received 5 more Moonlanders, so now have total of 8. I have a Sipolar hub capable of running all 8 but would like to split between 2 different coins/pools.

I understand how to write the bat file in Windows - com ports for each usb, but how do you do it with a Raspberry pi setup?

Thanks

Same deal, you just use linux syntax which is /dev/ttyUSBx where x is device number.

Has anyone used eyeboot 49 port self powered hub for running these moonlanders? I was wondering how many of these moonlanders you can run on it, if anyone has experience with it.

This is what I use for testing the sticks before I ship them out. It can reliably run 20 or so before issues kick in, obviously depends on clocks etc.

This kind of makes sense assuming the numbers are correct for 32GB per 6 asics on each board. That means about 5GB of memory for each asic. If they are really using DDR3 (which again makes sense for an ASIC style eth design, since 96 GB of GDDR5 would be crazy expensive), they could probably get away with a 256 bit memory bus running at 933mhz (near max of DDR3). That would translate to about 60GB/s per asic or about 7mh, x 6 = 42 MH per board or 126 mh per machine at probably 200-300 watts.

Nothing crazy but is the equivalent of a 6 GPU rig, for probably half the power cost at half the USD cost.

Bitshopper.de is out of stock from quite some time. Have they ordered any stock resupply from you?
And what do they mean

Quote

1 Futurebit Moonlander 2 (Edition bitshopper.de) in Aluminium box

What box?

Yes they will have lots of stock available starting this week

~~Still not in stock or they had little stock that ran out.~~ Now in stock. WTH. Huh

Wow. Nice! Order is out.

They are acting strange. Now it's out of stock again. Really hard to say if they are throttling orders or simply taking payment for products not really in stock. Thing is, my order is still processing. Will report back when it actually gets shipped, though it would have been enough time to be shipped by now.

Nothing strange about it. Europe demand is through the rough and he is listing his in stock units as soon as they are assembled and ready to ship out in batches of 50 or 100. They just sell out within a day or two. All orders currently are in stock units, we don't take payments for units not in stock unless it is explicitly stated by my distributors and myself that its for a pre-order.

Oh and a question to jstefanop or anyone else honestly.

Windows 10 Pro:
So you have your MLD running and in the command window you hit Q for quit.
At that point the fan goes into a super fast full speed! Why?
If you then unplug the stick and plug it back in (I am using a powered hub) the fan still runs at hyper speed.
If I then run BFGminer again, the fan slows a little once it starts but not at the original speed it was running at. It's still running faster.
I have to reboot the PC to solve that. A reboot and then plug the stick back in and the fan is quite and lower speed again.
Run the BFGminer again and all is good. No hyper speed fan.

Anyone else notice this? Any way to resolve it?
Anyway to read the fan speed on this thing?

Thanks,
Bob

The fan is dumb, and its speed is based on the input voltage. When you first plug in the stick is not drawing any power you getting full 5v out of the port and so is the fan (so its running at full speed). Once you start hashing the voltage can drop down to as low as 4v depending on how bad the 5v supply powering the port is, which in turn slows down the fan.

Quote from: thebosz on February 09, 2018, 09:32:23 PM

Maybe I'm dumb, but is there an easy way to tell which device is which?

In BFGminer, I have the list of 6 devices, MLD 0 - 5. Occasionally I'll get a message of "MLD 5: ASIC has stopped hashing, attempting to restart".

I know it's because of power issues.

But I can't seem to isolate the problem one.

I've tried to disable it through the "manage devices" menu, but all devices keep flashing leds.

Is there some trick to figure it out?

Only way is to match the serial number in bfgminer to the device. The disable function is currently not implemented in the driver, but it will be in the next release.

Happy to announce that most Batch 2 Pre-orders have now been shipped out, and all worldwide distributors finally have stock! Supply is still tight, but I don't see a need for a Batch 3 for the foreseeable future, so if you want a unit now is a time to grab one (retail pricing currently on direct distributor websites is the lowest price you can get them).

Thanks to everyone once again that participated in the Batch 2 Pre-order and made this another awesome success! We now have thousands of new people into crypto, and will still be aggressively using the Moonlander 2 as a tool to get more people excited about crypto and its future!

I have 11 mld2s, all on one hub. No problems, until yesterday. Now one MLD isn't well recognised by the hub anymore (irrespective of the USB port I put it on): sometimes it does not show up in windows COM drivers (and I get error message 'unrecognised device' or something like that), sometimes it does but it refuses to communicate (the yellow light maybe flashes once but that's it, and it does not show as a MLD device in bfgminer). First I thought the USB chip on the MLD was semi-fried for some strange reason.

Now, when I plug that same device in a USB port directly on my PC (same PC as the hub with the remaining 10 MLDs is connected to), it works fine, it is properly recognized by windows and hashes away just fine. I have tried powering my hub on/off etc, but didn't help. It drives me nuts. So I guess it is something in the hub, but it can then only the hub controller because the power and the individual usb ports are fine by themselves. It's a 19 port Eyeboot hub, I think jstephanop also said that eyeboot hubs are not the greatest (when stretched).

Try holding it down when plugged into the eyeboot hub...its most likely not making a good USB connection, and the fan vibrations etc are making it disconnect. For some reason the eyeboot USB ports can get deformed easily, and then the sticks don't make good contact.

I noticed you updated bfgminer to 5.5 for your fork.

1) Will you be releasing new binaries soon? Any advantage to 5.5 for ML2 users?

2) Can we configure to include GPU with your fork?

Yes, I'm testing the 5.5 updates first to make sure there are no issues, and then updating my driver with additional fixes/features. Should have new binaries up by friday hopefully.

My binaries have a lot of stuff stripped including GPU stuff in order to keep issues at a minimum, but you can compile on your own if you want GPU support etc and should work.

I mean,i will install Virtual Box and inside it Windows 10,now.....moonlander could work? Or it need an “hardware” machine to run?

Haven't tried so I am not sure. You can install Ubuntu 16.0.4 in Virtual Box too.

i have install virtual box and then ubuntu...i try to instal the UART driver but....i'm completely new at linux,how can i compile it? i try to read the note but i'm not able to do anything...... Cheesy

EDIT:

I have windows 10 running over VirtualBox (over OS X 10.11.6),under the virtual machine the stick work great.

I have set up 796 clock,core .75 volt and memory .85 volt,it work at 6.26 Mh/s (from bfgminer report,litecoinpool worker is at 4,463 H/s) and HW Error at .79%~.80%

What do you think about it?

Daniele

Looks good to me...for linux you don't need the UART driver...its already part of the kernel.

and mac os support is 10.12 and 10.13 (with UART driver workaround posted in OP). 10.11 is NOT supported.

Obviously there's something wrong haven't you read the previous post where i clearly say that i have tried contacting BW and it did not work .

Great help reminding me to contact BW , amazing effort .

Again sorry for hurting ur feelings snowflake , now i know people wasting their hard earn money < ur over sensitive feeings .

PS:i never screamed at you , criticism does not equal screaming.

Easy now! He just reviewed the miner. We operate the L21s as well. Although we mostly run Bitmain products, we do have 12 of the L21s. I can tell you that it's not a latency issue. It doesn't matter which pool you point to, it's still a problem. There is a high number of rejected shares on all of our L21s (10-40%) and the reported hashrate (as a result) mainly fall mid to upper 400 MHs.

This is a real issue. I am not sure if BW will fix it or not. I know that Hyperbitshop's CEO just told a friend of mine that he would get to a firmware update in a few weeks. But, seems as if Hyperbitshop isn't selling the miners any longer since they are listed on the BW.com site.

It is a software issue...I work pretty closely with them since my miners use their chips. Been trying to get a L21 unit from them to help them fix the software but so far they have been out of stock and cant send me one.

^ ahh sorry yes misread the comment. Saw eyeboot and thought you were talking about getting a hub from him. Yes if you plugged it directly into the Pi, thats your problem. The pi is cutting off the stick due to drawing to much power which a direct connection to the Pi can't handle.

Just got my FutureBit Moonlander 2 from eyeboot.com today!

Anyone come across the following error when starting up bfgminer?

Code:

Here's my start_moonlander2.sh script bfgminer_5.4.2-futurebit2_linux_armv6.tar.gz

Code:

./bfgminer --scrypt -o stratum+tcp://us.litecoinpool.org:3333 -u <redacted_user_name>.1 -p 1,d=128 -S ALL --set MLD:clock=600

The Moonlander is plugged directly into a Raspberry Pi 3 running Raspbian 9.1. And I'm using the bfgminer from bfgminer_5.4.2-futurebit2_linux_armv6.tar.gz - https://github.com/jstefanop/bfgminer/releases/tag/bfgminer-5.4.2-futurebit2-beta2

One of your sticks are loose in the USB port. I use eyeboot's hubs for my testing as well and unfortunately its the one drawback of them. The ports themselves are not of the best quality, and with the vibrations of the fan they sometimes lose USB contact with the pins and causes this error.

For some reason I'm having trouble getting my moonlanders running. I bought two of them along with one of the recommended powered USB hubs. They are showing up in Device Manager and the fans are running along with the green power light.

I installed the driver from the link provided and also downloaded the recommended BFG miner, but when I fire up the BFG miner, it doesn't recognize the moonlanders. It sits there saying " [2018-02-05 13:23:18] Waiting for devices; press 'M+' to add, or 'Q' to quit" for a minute, and then goes to this screen:

pause

I'm using Windows 10, and I also checked in the Device Manager, and it looks like they are showing up on ports COM3 and COM4, with the names 'Silicon Labs CP210x USB to UART Bridge'.

Set frequency to 384, and let me know if you see any yellow and red LED flashing as soon as your startup bfgminer. Also try running just one plugged directly into your computer USB port to rule out any issues with hub etc.

I ran into something else interesting along the way the other day when I got the last pair of these. I had been running them on a USB2 bus and the 6 were always fine at full speed. After stepping up to 8 of them, I'd consistently see one slow down after a while. Moving them over to the USB3 bus of the same system fixed that. I wouldn't think the USB2 bus was saturated, so I don't really know why.

* Are you using external fans?? I could not see it so quickly from your picture. If not, have you measured your ASIC temperatur (small heatsink)?
* Why are you using 4 of these hubs with just 2 MLDs each if you had both a USB2 and a USB3 hub that (I understand from your message) could take all 8 in one go?? (where only the USB3 gives all units at full speed)?
* I have similar issues with running a certain number of MLDs just fine, and adding one or two more one or two units slowing down. It has been suggested it is an issue with USB hub getting 'stuck'. However, I am close to certain that on my hub it is a power issue and it could be that the powerlines in your USB 3 hub are either fatter or differently laid out on the PCB. It maybe takes a small additional voltage drop to cause problems. These babies draw a lot of current. That's my experience. But whatever the cause, I have seen similar things too.

Great stuff. I am running 6 at 924Mhz and another 5 at 832Mhz (for the above reasons; all on one USB3 hub). Getting about the same as you, slightly less. I also have slightly higher hw rates (but then I tuned core voltage down as much as possible to reduce power and heat).

Yes, a 120V fan cools these. All the hubs are the exact same USB3 hub, all of which were connected to a USB2 port on the computer initially, but when seeing one slow down after upgrading from 6 to 8 units, I moved the connection to a USB3 port which resolved that. You may have better luck using more than one hub, I certainly have.

Yea that would make sense...the less load you have on the power supply of these cheap hubs the more stable the sticks will run.

I'm still curious. I show this makes a dime a day.

You guys are really spending money on a dime day?

If you think most people are buying these for immediate profits, you don’t understand who is buying them and for what reason.

Sidehacks 2-pac bitcoin sticks make 2 cents a day, and people are still buying them for 100 each Wink

Quote from: aballen on February 03, 2018, 02:23:20 PM

Really interesting. I have 4 in my office with the window cracked, super cold in there. With the core voltage a .819 I'm able to run them stable at 832. <.5% errors. I have not touched the memory voltage.

Increasing the speed certainly ups the error rate. Is anything under <2% really optimal? I want to see it at close to 0 as possible, maybe that is silly, I feel satisfied at<.5%. I start to worry over 1%.

My tinkering has been minimal, but as an example if I go to a speed of 852 error rate is ~1.2%, and increasing voltage does not seem to help, maybe it just creates more heat, or my increase is too much?

Not trying to be greedy, 4.7mhz is pretty good, but I was hoping to get to 5mhz, so I'm curious how you guys nudged your speeds up.

What are your voltages?

Up to 8 of these now which is probably as far as I will go. All are running happily at max speed and completely stable.

Impressive....are you running at max frequency? Do you have core voltage maxed out as well?

No way he's running max clocks AND maxed voltage...regulator would definitely blow up or shut down due to over-current protection. Definitely don't recommend running these at max clock, but running one of these at max clock this stable is impressive...8 all one the same hub...thats crazy!

Hey, @jstephanop, you made this awesome stuff! I am running 6 mlds at 924Hz (plus 5 at 824Mhz) all on the same hub, with the pots tweaked down as per your instructions, my HW rate is a little higher, at .9% and my hashrate it a bit lower, at 5.3Mhz/unit, instead of just over 5.4Mh/s as with @dem0nlord. Been running stable without restarts for weeks now. I got (borrowed) an IR temp meter, the 824Mhz MLDs I am running without stockfan and they are at ca 44degC, the 924Mhz I am running with stockfan, and they are about the same.

Anything past high 4's pretty much comes down to silicon lottery. While the batch of chips I have been getting has been pretty good in terms of variance, you just might get a chip that runs at max clocks cool all day long, and one chip just wont go past 4.5 without alot of power/tweaking.
