Support Thread for GekkoScience Terminus R808 Miner

######################################## #Support Thread for GekkoScience Terminus R808 (BM1384) Miner# ######################################## Check out the Terminus R808 **Release Announcement Link** ================= =Community Appreciation= ================= Yay! Huge shoutout to everyone for the ongoing support from the community. These little miners keep improving thanks to you all. Here’s what the ports look like. We’ve got a USB-A for 5V power output and a mini USB for controls. You can get 12V power from either a PCIe 6-pin connector or a 2.1/5.5mm barrel jack (for using a power brick). The blue knob lets you tweak the core voltage from around 0.63 to 0.80V at the chip level, pretty much the same as the 2Pac. You can set it up with either a vertical (like in the picture) or a right-angle (front-facing) adjuster. This miner has a built-in microcontroller that manages fan speed with PWM, detects when it’s in "ZOMBIE" mode, and resets the chips on its own. It also shuts down if it hits 80C to cool off and will restart mining below 70C. It’s a 100mm square sitting on rubber feet, but there are M3 screw holes on each corner for stacking or mounting in a case. This miner is equipped with 8 BM1384 hashing chips. I’m planning to stick with this design going forward, so future versions with improved chips will fit just fine. For those who love flashy lights, it has a blue LED that lights up and blinks white when shares are returned. ================= =How to Get Started= ================= Same setup as the 2Pac. Just follow the build instructions to compile from source and get it running. Run syntax: *nix [if you don’t have root level access

Apologies, totally jumping the gun here, super grateful to be in the early receivers group. Connected my new Terminus to my Ubuntu PC controller as soon as I got it.  The PC was running with a COMPAC and a 2PAC in the stock USB 2.0 ports, 150MHz and 100MHz respectively.  CGMINER found the 808 right away, ran it at 100MHz, and CKPOOL started taking shares.  I saw this awesome threesome get up to a 5 min rate of around 110GH/s. I checked my user account 20 mins later and the rate was down to the original 19GH/s.  The Terminus was continuously failing and restarting.  I took everything apart, pulled the latest VTOHANG fork of CGMINER, and recompiled.  I connected just the Terminus, started up CGMINER, using only pool switches, piping it to log.txt: I tried a couple different pot positions/voltage levels, starting clock rate switches (75, 100, 150) in the startup command,  to no noticed change.  I put it back to the "5:00"/max voltage/min resistance setting (where it was when I got the 808). After this I unplugged the Terminus, plugged in my 1 and 2 chip USB sticks, and came back up normally. So a couple questions:  Does the Terminus require a Pi controller?  Thoughts on what I should try next? Thanks

I just moved the latest stable terminus changes onto the master branch.    Do another pull and rebuild. A better start and restart codeset for the Terminus is there.

Code build : ba94edb  (follow-up to last post) Terminus updates.  Important for R808 owners. windows build: http://23.108.83.14/images/cgminer-4.10.0-windows-gekko-ba94edb.7z notes: clean up terminus startup / restart. expose ramp up options: starting frequency / step up frequency / step up delay --gekko-start-freq <arg> Ramp start frequency MHz 25-500 (default: 100) --gekko-step-freq <arg> Ramp frequency step MHz 1-100 (default: 25) --gekko-step-delay <arg> Ramp step interval range 1-600 (default: 15) installation: rename folder -> checkout (see first post) -> autogen -> make or pull -> autogen -> make * if you have trouble... report it here.

The start frequency is obvious, but how do the step and delay settings work?  Where does it stop? Thanks!

Checked in a small update to remove some additional test item that leaked over. Pull and build if you are following along.   windows build: http://23.108.83.14/images/cgminer-4.10.0-windows-gekko-d245c0d.7z Updates may be happening frequently the next 2-4 weeks so check back and do a pull while I iron out any reported anomalies. The frequency defaults to 150Mhz.   You can change that by requesting a new frequecy using --gekko-terminus-freq <arg> Set GekkoScience Terminus BM1384 frequency in MHz, range 6.25-500 (default: 150.0) The previously mentioned options are ramping values. default: start at 100MHz, increment by 25MHz (step) every 15 (delay) seconds. (edit) So with the config save available and working, make sure you edit there if you've saved out a config file.   It takes precedence over any command line options.   Just a reminder in case you're in a situation where command line options are not applying.   Adjust or remove the default config file [~/.cgminer/cgminer.conf] if it exists from a previous config save.

Hey VH/Sidehack. Super excited for this release. For the barrel jack connector, i saw on the announcement release, it uses about 4.5 amps at 12V. So based on that, a standard LED strip light power pack should work. something like this? http://amzn.to/2FsOMP1 100MHz (44GH) 660mV/node 2.64V total; 12V 1.4A for 16.8W/0.38J/GH 125MHz (55GH) 660mV/node 2.64V total; 12V 1.7A for 20.4W/0.37J/GH 150MHz (66GH) 660mV/node 2.64V total; 12V 2.0A for 24.0W/0.36J/GH 175MHz (77GH) 693mV/node 2.77V total; 12V 2.5A for 30.0W/0.39J/GH 200MHz (88GH) 715mV/node 2.86V total; 12V 3.1A for 37.2W/0.42J/GH 225MHz (99GH) 755mV/node 3.02V total; 12V 3.8A for 45.6W/0.46J/GH 250MHz (110GH) 770mV/node 3.08V total; 12V 4.4A for 52.8W/0.48J/GH 275MHz (121GH) 770mV/node 3.08V total; 12V 4.9A for 58.8W/0.49J/GH

that is junk  I will get you a better link this will do 3 units https://www.trcelectronics.com/ecomm/pdf/hrp200.pdf https://www.trcelectronics.com/View/Mean-Well/HRP-200-12.shtml 88% efficient use with these  as they are 22 ga not 24 or 26   just cut off the end that does not fit. https://www.ebay.com/itm/10-Pack-of-36-22AWG-DC-Power-Cable-Male-to-Male-5-5mm-X-2-1mm-Barrel-Plugs/192150513189? better yet buy these https://www.ebay.com/itm/5-5mm-x-2-5mm-5-5-2-5-DC-Power-Barrel-Jack-Screw-terminal-Pack-of-2/381843414717? https://www.ebay.com/itm/50-Speaker-Wire-18-AWG-Ga-Gauge-High-Quality-Car-or-Home-Audio-Guage/361647935149? and cut to length  3 rigs per psu  88% efficient

You can also use a power supply from a computer like I did: I had a spare one laying around.

that works well .  just as long as he does not use those bricks he linked

Guess I'll be the first one with a problem    I had 2 of them go zombie and didn't look like they were coming back. I power cycled one/ unplugged the usb after ejecting it, plugged it back on to Nothing. Not sure what I am doing wrong....Help pls

Start with the latest code build available in the opening post.    Looks like you are a couple of builds behind.

will give that a try and reboot my computer just in case, thx

Not sure what this is....Duplicate Nonce?  [2018-02-24 19:59:20.939] GSE 0: Duplicate Nonce : 03c760ca @ 04 [03 c7 60 ca 84 00 00]  [2018-02-24 19:59:22.952] GSE 0: Duplicate Nonce : 05a0d226 @ 1b [05 a0 d2 26 9b 00 00]  [2018-02-24 19:59:26.234] GSE 0: Duplicate Nonce : 187de424 @ 15 [18 7d e4 24 95 00 00]

debugging that is left on... it's normal for it to appear for a brief moment when the frequency or chip state changes. i'll move it to a different log level on the next build.

So I got my four shiny Termini in the mail today... and I can't get them functioning. Anyone willing to help out? I am using the included power supply with the build kit sidehack included for each one. My controller is an old laptop I have lying around running WindowsXP. I downloaded VH's build for windows posted above. I can get the things mining but I am running into problems: 1) The laptop has 3 usb ports. I, in my eagerness, ordered 4 units. I was thinking I would just plug two of them into a USB hub and then the hub into the controller - when I do that cgminer recognizes all 4 miners but all 4 function at a horrible hashrate of 10-20ghash. If I pull off the splitter and use only three miners the average is around 60ghash each. What is going on? The power supply is separate for each of these and not supplied through the USB splitter, so I don't know why it would drop the hashrates of all the miners, even the ones not connected to the splitter... 2) When I get three of them up and running, within less than 3 minutes or so, one of them invariably gets a failure warning and resets. CGminer then assigns it a new miner number and the process with the ramp up starts over again. Withing 20 minutes I start out with miners 0, 1, and 2, and end up with something like 1, 12, 11 from frequent failures. Occasionally the failure causes CGminer to crash and I either have to restart the system or unplug the miners and restart GGminer to get it working again. I'm not a tech guy - I work on humans not computers - so please help me in your most dumbed-down language possible Thanks in advance!

What frequency are you trying to run at? Does your old laptop also have old USB (like 1.1 vs 2.0)? It's incredibly unlikely that power is costing you hashrate. Power's sort of an all-or-nothing deal. What could be costing you is trying to run too high a frequency for the voltage setting and the string trips out and resets, or your USB throughput sucks and they're not getting enough work to stay busy.

Hey! Sidehack! Just wanted to say personally how awesome these are, despite my incompetence... I'm pretty sure I've got USB 2.0, I'll look into that. Interestingly, I moved these into another room and probably mixed up which miner was plugged into which USB hub - now I'm no longer getting the failure error or CGminer crashing - but before when it ramped up it would eventually reach the default max of 200mHz before things started failing. Now its not going above 150 and I changed nothing except which miner was plugged in where. Odd. Even so, at 150 my hash rate is only 30-40 per miner which is below the anticipated 66 from the specs above, so I still have some work to do. I suspect it may indeed be the voltage setting. How do I adjust that? These didn't come with an instruction manual so I want to make sure I do this properly without potentially damaging the units...

New build is available (eb57c34).  Git pull and build on *unix for latest. - force continue on partial usb write failure.   ^ better resume path in a very specific reset scenario. - moved duplicate nonce from log_warning to log_info. windows binary: http://23.108.83.14/images/cgminer-4.10.0-windows-gekko-eb57c34.7z
