Braiins OS+ support thread

[Artemis3]

I'm making this new thread to focus in support issues and not get derailed with off topic things anymore.

Remember that this is by my own initiative, official support is provided by opening a Support ticket, or in the Telegram Group.
Official web page is here: https://braiins.com/os/plus

Version changes are here.
** Remote install method ** Optional for BeagleBone Black and Zynq, required for AmLogic and Cvitek:
- Download the latest Braiins Toolbox for your OS:
Linux x86_64 (Intel / AMD PCs, etc).
Linux aarch64 (Newer Raspberry PI or clones).
Linux armv7 (Older Raspberry PI or clones).
MacOS x86_64 (MacOS 12.4 or later).
Windows x86_64 (Windows 10 or later).

Example downloading, unpacking and running from a Linux terminal in a PC:

Code:

wget https://feeds.braiins-os.com/braiins-toolbox/assets/latest/braiins-toolbox-linux-x86_64.tar.gz && tar xvzf braiins-toolbox-linux-x86_64.tar.gz && ./braiins-toolbox

Running without options starts a local web server: http://127.0.0.1:8888 point your web browser to it and use the web UI.
Run it with option --help to see more options and CLI usage.

If you want to access this from another PC in your lan (example you are running it in a headless Raspberry PI), add the -g option to allow access like this:
./braiins-toolbox -g 0.0.0.0:8888 and then point your browser to the IP address where the toolbox is running, same port.
** Micro SD method ** Optional for BBB and Zynq:
- Download the image for the micro SD (max 16g):
x17 Zynq/Xilinx/7007 (22.05).
S9, S9j, S9i Zynq/Xilinx (22.05).
(S9 only) move jumper jp4.
- Flash the image from a pc with BalenaEtcher, Rufus or dd.
- Insert the micro SD card and reboot the miner.
- Log into the miner with a web browser: user root, no password.
You can find its IP with bos-toolbox listen + ip report button, or AngryIP / Nmap.
— — — — — — — — — —
- (Optional) Install to NAND from (System > Status >) System > Install to NAND (Only 22.05 with S9/x17 control boards).
(Old) bos-toolbox for S9/S17: Linux x86_64 - Windows x86_64


Braiins OS+ is a full replacement firmware made from scratch. Braiins has to figure out hardware support without any aid or documentation from manufacturers, for this reason the number of supported ASIC miners is limited. Braiins takes no shortcuts like others that illegally mod existing firmware and infringe cgminer's intellectual property (see Section 8), therefore its impossible to support new miners that have been just released. It takes countless hours of research and development to support each new variant or model in a manner that is clean, safe and efficient.

Braiins OS+ is made in Czechia part of the European Union with the highest standards of excellency.

Unlike others who don't care about burning your miners, Braiins cares. Only Braiins OS+ prefers to stop using what it doesn't like, others are "do it no matter what" mindset. Long time farm operations save with extended hardware longevity and unrivaled uptime because of this, which is what makes profitable what others lose in downtime and repairs. Also your company won't be liable for the use of pirate software that funnels money to an OFAC sanctioned country. Braiins OS+ is CLEAN, nothing from the manufacturer, nothing from cgminer, designed from the bottom up, not patched with a gazillion holes, mem leaks or a reckless uncaring and ridiculing attitude. Those incapable of writing their own mining software are no competitors, but pirates.

Braiins as a company exists since 2011, 13 years of unparalleled experience; and it shows, the industry knows the truth.

Since Braiins OS+ release in 2020, the results have always been the best efficiency, often resulting in a "generation leap". For example:
People who use it with the S9, can make 74 J/TH, same as S11 with stock.
People who use it with the S17, can make 29 J/TH same as S19 with stock.
People who use it with the S19j, could make 21 J/TH same as S19 XP with stock.
People who use it with the S19 XP, can make 18 J/TH same as S21 with stock.
People who use it with the S21, can make 15 J/TH same as S21 Pro with stock.

Clean, safe, efficient. Braiins OS.

For most of 2023, you could have made your XPs achieve the so called 1XJ/T ahead of the manufacturers newest models, by simply using Braiins OS+.

Even if you subtract the dev fee, you still get better than others with "zero fee". For example 101.2*0.975=98.67 1856.3W/98.67TH=18.81J/T (normalized against "zero" fee). By using Braiins OS+, you support the development of a truly independent and clean alternative developed from scratch.

The reason why Braiins always achieves the best efficiency is because of its unique autotuning, a deep and continuous process others aren't able to imitate no matter what they claim, since they don't get it and take shortcuts which are inefficient and never adapt truly to your hardware. Its not who does it first, its who does it best. Worldwide market adoption has been overwhelming, and for good reason. Think of cars, what quality you get from Europe, America, China and Russia...

And on top of that, enjoy the 0% pool fee by using Braiins Pool. Since you are already paying for Braiins OS+ you get the benefit of using Braiins Pool for free! Two products for the price of one!

Finally did what you needed to do. I mentioned you should do this in your other thread years ago.





I have a question will you consider doing bitmain L7?

Also I was considering getting some 'better' psu's

this says it will work with your software
s17 after market psu
https://parts.kaboomracks.com/collections/power-supplies/products/alpha-miner-psu-4kbm17-apw9-new








the 2 below do not say they work with your software
s19 after market

https://parts.kaboomracks.com/collections/power-supplies/products/alpha-miner-psu-4kbm19-apw12-new


s19 modded

https://parts.kaboomracks.com/collections/power-supplies/products/bitmain-apw12-psu-modified-from-used

they are supposed to be better made but will they work with your software?

[Artemis3]

The only aftermarket psu i know that works right now with Braiins OS, is the Gullpower, specifically the GPW121215-8KW immersion PSU. Some crazy person managed to pull "Over 9000!"™ watts at the wall with it... So the thing does deliver.

The development team is also studying the Alphaminers, but for some reason those need extra firmware support, so i don't know when they will get supported. Last time i read they were making the 7kw model work, so i think it should get support sooner or later.

I suppose the model you linked was tested by the reseller so they would know, when i get confirmation from a third party I'll add it to the list.

Other aftermarket brands/models are unknown if they would work or not. The Gullpower was discovered by adventurous people who just tried.

Its the same way others also discovered the Zynq control boards C87 and C84 "just work", unlike that Beaglebone and Amlogic trash which imo are a waste of dev time and resources (they should be just thrown out), even if its theoretically possible to make them work, they do suck, very low capacity, poor cpu, etc. For example with the BB tuning takes much longer as it can't do all hashboards in parallel. Even Bitmain won't ship them if you break your board and ask for a new one you will get the C87 which is perfectly fine like the other Zynq.

Braiins is fully committed to Bitcoin, so the other algo asics will not be supported. Its also the reason altcoins were finally removed from the pool.

Fair enough about the L7

I will likely order some of those psu's from kaboomracks in the next few months. As I get tired of the s17 psu's burning out.

[NotFuzzyWarm]

Wouldn't finding a drop-in replacement PSU mainly be a matter of knowing the specs for it? Namely:
Output voltage range
Output current
Max power out rating
And here's the most important bit -- how the controller talks to the PSU to set the voltage output fed to the hash boards and if/how the controller knows what the PSU is doing. Is it simple 0-5v analog coming from a DA converter or analog output port on the SoC? Serial coms like I2C? PWM signal? etc.

[Artemis3]

Unfortunately no. Bitmain played dirty tricks again.

In regards to the "J" miners, there are two different ones: Old ones, with pic in the hashboard, New ones without it.

You can only recognize the "New" ones when they come from factory with the PSU APW121215 rev D or later. You cannot use older PSU revisions with these "New" miners as it lacks the detailed power control. Old miners should probably work fine with the New PSUs though.

You cannot recognize the "New" hashboards without removing heatsinks, so be very careful with mix matching PSUs. Once Braiins OS supports the New miners, the log will alert if the old rev PSU is connected to new miners.

The APW121417 also uses these pic less hashboards.

I suppose the aftermarket PSUs will all just have to adapt for the "New" miners, but who knows.

Yeah, gone are the days where the PSU only supplies 12V... It changes dynamically within a range. Well the control board itself is still getting 12V (and feeds the fans with that).

Actually Frodocooper complained about these bespoke psu's back in 2018 when the s15's came out.

it is a pain in the butt if you have cheap power and a slightly older psu dies no one sells them and your gear is no longer any good.

I have 0 apw8's spares
I am down to 1 apw9 spare
I have 0  apw12 spares

So keeping older gear working just gets harder.

[NotFuzzyWarm]

Actually Frodocooper complained about these bespoke psu's back in 2018 when the s15's came out.

And as I said back then: There are 2 reasons for it.

1. Using more PCIe connectors to feed a multi-kw mineris a bad idea. Too bulky and already proving needlessly unreliable because of the connectors being pushed to their limit and adding insult to injury them often being plugged/unplugged many times over the life of a miner and or PSU. PCIe connectors have a very small number of mating cycles before they begin seriously degrading.

2. Wall plug power efficiency. Today's best Platinum 12vdc PSU's are what - 95% maybe 98% efficient? Now that 12v was being dropped down via a final regulator on each hash board to whatever Vcore is being used. Typical string voltage was what, 7.5 to maybe 9vdc? At best the on-board regulators were *maybe* 85% efficient so...

End result is that by losing the 2nd stage Vcore regulator losses using integrated PSU's that directly set the voltage results in more TH/kW plus by using bus bars it eliminates the high current connection problems. Oh, being able to use a higher string voltage lets ya use longer strings of chips so more TH/Current drawn through the string.

The main tradeoff is that the PSU is setting the Vcore string voltage for ALL of the boards. Um, since we all know that the ideal voltage for any single board can vary a fair bit, that means the tuning process ends up with the best *compromise* voltage to reliably run the weakest board even though the other boards may perform better with a different voltage.

Now as to *why* BM,  Canaan, et al can't seem to have a more reliable PSU built is a mystery to me. It ain't rocket science to design a multi-kw PSU...

Looking at the APW8 schematics posted at https://www.zeusbtc.com/manuals/Antminer-APW8-Power-Supply-Repair-Guide.asp it looks like they use I2C to talk to the PIC in the PSU. Yes the PSU also seems to have two distinct ranges for the DC output: They describe it as 15.9-16.3v and then give an upper range of 19.92-20.5v. Point is, assuming it *does* use I2C and you know what format the commands are sent to it are, it should be easy for some 3rd party to make a compatible PSU. Just have your firmware be able to identify what the hash boards are & need for voltage and talk to the PSU...

[mikeywith]

Now as to *why* BM,  Canaan, et al can't seem to have a more reliable PSU built is a mystery to me. It ain't rocket science to design a multi-kw PSU...

It's because they are cheap, they try to reduce the cost at the expense of other things, I think they set a fixed price for the cost and ask their engineers to design something within that price, all these asic miners manufacturers companies do some stupid shit that nothing justifies it except being cheap.

MicroBT do make some solid PSUs and they have a very low failure rate unlike Bitmain and Canaan, but for some reason (probably cost again) they suddenly switched from using 6 flat pins to 4 square pins, so if have a miner that has the flat pin connector when you change the PSU you are going to have to buy a new set of fans and those fans are not cheap, by doing this, they make keeping spare parts a harder job, now you need to have spare fans for both PSU types that are used by the same miner model.

So long as it does not die within warranty they don't care. It's not a lot different then how a lot of things are built today.
Get it to X price and design it to work for Y amount to time with Z reliability. It's not like there is a lot of competition in the space. A few vendors, and although some are better then others there are none that are Toyota HyLux reliable.

[mikeywith]

So long as it does not die within warranty they don't care.

and besides that, they probably know that most people won't send a whole unit just to get a PSU repair, which is what is happening, many PSUs fail within the warranty timeframe and they don't get any repair tickets for that, because it's almost always cheaper and more reasonable to just buy a spare PSU locally than having to send the miner in for a few weeks/months and still have to pay shipment fees and all, so they know they can easily get away with PSUs that die in no time.

none that are Toyota HyLux reliable.

lol, I can vouch, my grandfather had a 1988 hilux  , it was a tank, when we were young my cousins and I would spend the summer in the farm, he would wake us up at 5-6 am to walk the sheep and we would come back at noon, he would take a nap and we would steal the car keys and drive it (actually abuse it) around the farm, we did some unintentional off-roading with it and we didn't even know how to probably shift the gear, honestly, we were barely tall enough to see what was in front unless it was a large tree , my Jeep now can hardly do half of that before needing a major repair.

Just Wondering ...

If I managed to get decent PSU produced, would there be a market for them to cater for the PSU BreakDowns. If anyone is like Me, Discarding the PSU and Replacing with a new one seems to be a far better way of doing things than pulling machines apart, sending a single component, waiting (IF they repair them) and having the machines offline for weeks sometimes (Being in Australia is a Pain in this case) and losing out on Hashing.

If there is a need for it, I would have no issues getting them produced and stocking them for such cases, and for the Communities to at least have an option to go elsewhere (to Us at CWI as an option) to source PSU units at a reasonable Price and actually being stocked with them - as long as demand is not too great of course.

I would be happy to supply a few for testing if that is the case.

Just an idea, and I hope I am not pushing an issue here. I know how We are with our machines and it is usually the PSU not the ASIC that dies WAY before anything else does. We have replaced hundreds of them in the last 12Months, which is why I started sourcing 'decent' ones for our Farms.

As for the OS - where would one go to request features for the FirmWare?

Hi, what is the command via SSH to 'Restart BOSminer'?

[Artemis3]

/etc/init.d/bosminer restart

or with bbb:

/etc/init.d/S99bosminer stop
/etc/init.d/S99bosminer start

[mondayshot]

/etc/init.d/bosminer restart

or with bbb:

/etc/init.d/S99bosminer stop
/etc/init.d/S99bosminer start

great, worked. thank you!

other question, I wanted to change fan speed — from 100% to 50% — while restarting BOSminer with the following command:

Code:

ssh root@192.168.1.199 "/etc/init.d/bosminer_monitor stop && sed -i 's/fan_set_duty(i, 100)/fan_set_duty(i, 50)/g' /usr/sbin/bosminer_monitor.lua && /etc/init.d/bosminer_monitor start"

but terminal says:

Code:

-ash: /etc/init.d/bosminer_monitor: not found

what am I doing wrong

Bitmain Antminer S9 with Version: 2022-06-20-0-288861e4-22.05-plus

[hZti]

Is there a way to stop the fans (Antminer S9) from going to 100% at startup. I use Braiins OS+ and have the noise level very low because I use only 600W. Since I need to restart the miner quite a few times depending on availability of power, this would be very helpful.

[philipma1957]

so I am looking to do a s19 pro 110th with this hashboard


https://vmssecuritycloud.com/product/new-authentic-bitmain-oem-s19-pro-s19-t19-control-board/


it does not have bugle bone it is xlynx

so what is my firmware link to run this and load an sd card

I did an 8db sd card with the x17+x19 firmware and it only mentions s17 and will not allow for programing .

so do I load it with the one that say bugle bone.

to be a person that does have some interest in running a lot of s19 pros

it would be easier if the file just read s19pro rathe than seem to be able to do both s17 and s19.

so for now no s19s are using braiins

[slurfius]

has anyone tried a c87 in a new s19 xp to get braiins os+ working on it?

[Artemis3]

That old trick for the fans no longer works, the script was changed, besides it can't prevent fans going 100% after power is cycled anyway. You could just switch to silent fans from the likes of Phantek or Noctua, make sure the S9 is configured for low power limit.

S19 Pro 110T works perfectly fine.
Why would you care what the file is called? Its the same file for both families, of course it works. Beaglebone is for beaglebone only.

If you plug the C52 or C49 you can even use it from NAND. If you have the others, you must use it from SD. Others meaning: C87, C84, C71, C55 they all work fine from SD only.

I don't like BeagleBones, they work (from SD) but the OS is more crippled, for example autotuning takes longer due to its low spec cpu.


S19 XP will be supported in a future release, it doesn't work yet, and its not a mere control board issue.

S9 w Braiins OS+ - haven't been able to connect to Zergpool. I think I'm missing some bit of syntax in the pool info. I am currently running a gekko setup with CGminer, an Apollo, and a couple of CPU's with XMRig - all on zergpool successfully. S9 is currently on another pool and I've mined on CK solo with it before.
I've tried everything I can think of to move the S9/Braiins+ to zergpool and it always comes up Pool Dead. I think I'm just missing something with the syntax.
Has anyone else experienced this? Interested in assisting my troubleshooting?
