Braiins OS & Braiins OS+ custom ASIC firmware: optimize performance & efficiency

[Artemis3]

With this new cgminer option added, I can now how full use (no temp sensors) of my R4 with Braiins! Everything else works, and I'm now running at 630 freq, 9.1v, and 9TH.

Sounds tempting considering i'm not even controlling the fan (its always at 100%), but without temps how do you know you are not overstressing the chips?

Currently mine is on the latest factory firmware and a board is set to 581Mhz while the other is set to 602Mhz, producing more or less 8.5TH/s

Was yours a Xilinx board with 1gb of ram?

It looks like when network disconnects and pool not available miners won't stop, keeps hashing and drawing power.

The other day I had a network failure, my avalone and T9+ miners stopped mining but S9 with bOS kept hashing and drawing power.

On their mining status page they were showing pools failure too.

Please take a look into it.

Is there a way to absolutely ignore temperature sensors of both PCB and chips (or just ignore the data from them)? I have bunch of S9 hash boards with broken sensors that reports temperatures in range from -64*C to 191*C and I'm willing to put them in work knowing the risk of burning/killing them... Right now I can force few to start, but once a broken chip reports a wrong data, the miner just shuts down...

Just add the options inside /etc/cgminer.conf and force the fan speeds since they won't be reacting to anything anymore:

Code:

"no-sensor-scan" : true
"fan-mode" : "speed"
"fan-speed" : "90"

The number in fan-speed means fan % speed, in the example its at 90 percent.

Does anyone know the roadmap for incorporating M10 support? My M10 has been an excellent machine for me, but I would like to have a little more control over some of its settings and Whatsminer's firmware doesn't allow too much flexibility.

thanks

I don't know anything about a roadmap, but for the time being they are unsupported. They mentioned a "full rewrite" at some point where they will add support for more miners.

So far only the Dragonmint T1 and the Antminer S9 are supported.

I have an S9 that was flashed through the gui and would like to return it to factory condition/OS.
I have read the braiins-os paper on how to, but must be missing something. I have also done searches but nothing is helping me.
Could someone please give me a step by step process to revert back to original state, or even point me in the right direction if those directions have been dummied down for folks like myself. Appreciate any help.
thanks.

see post #273 and before

Here are the instructions for if you do not have a backup from when you upgraded to bOS

1.) create empty directory backup
2.) create text file mac (without any file extension)
3.) write one line with MAC address to the file mac (you can obtain your MAC address from web interface Network -> Interfaces -> MAC-Address)
4.) compress the file mac with tar using gzip compression and store it to the backup directory with a name config.tar.gz
5.) create a file called uEnv.txt in the back up directory containing the following information:

Code:

recovery_mtdparts=mtdparts=pl35x-nand:32m(BOOT.bin-env-dts-kernel),144m(angstram-rootfs),80m(upgrade-rootfs)

6. Download recovery firmware from bitmain (for this example Antminer-S9-all-201812051512-autofreq-user-Update2UBI-NF.tar.gz is used)
7. install python (using information provided on Braiins page https://docs.braiins-os.org/python-install)
8. make a folder called backup
9. put the factory image in it, along with two more files: uEnv.txt and config.tar.gz (that contains mac adress)

in python You need to run:

Code:

python3 restore2factory.py path/to/backup ip_hostname --factory-image path/to/Antminer-S9-all-201812051512-autofreq-user-Update2UBI-NF.tar.gz

i ran command :

Code:

C:\python\braiins-os>python restore2factory.py backup/ 192.168.2.244 --factory-image backup/Antminer-S9-all-201711171757-autofreq-user-Update2UBI-NF.tar.gz

ps:
i heard they changed something in the last iteration so this could not work

it is stated:

Using factory firmware image
On Antminer S9, you can alternatively flash a factory firmware image from manufacturer’s website, with FACTORY_IMAGE being file path or URL to the tar.gz (not extracted!) file. Supported images with corresponding MD5 hashes are listed in the platform.py file.

Run (on Windows, use python command instead of python3):

Code:

python3 restore2factory.py --factory-image FACTORY_IMAGE your-miner-hostname-or-ip

so, i think you can skip step 9.

[Brickman67]

Thank you for that info Velles....
Appreciate the effort and time... it's been a bugger for me and you laid it out there nicely.

Just to say that I have tried BOS on T9 and it didn't work.
the miner did boot and hashing but the interface kept being lost between recognizing 63 chips or 57.

As i said before, currently only the Antminer S9 and the Dragonmint T1 are supported, nothing else. This might change in the future, but for the time being, don't use it with other models.

was just giving it a shot. have few T9s I can spare.

Looks like I can run a 57 chip T9 board with braiins if I have one s9 63 chip board in the machine also.
Chip temp not showing on awesomeminer for the t9 but appears to run great.
Also, just had an R4 burn up wires and a corsair psu.
R4 dead. Controller ok. put braiins on it and stuck it in an s9 shell. Works great.

Just got an s9 on ebay and it was running braiins. Threw me for a bit. Just used to stock Dec 5 2018 firmware.
braiins is great. Much faster booting, led sequence very good, quiet. A bit more sane.
Looks like braiins is my goto. Wish it would work on old controllers. Have a few 550 and 600 s9's with older controllers.
Very pleased.

[Artemis3]

This time there are not many more details, but here it goes in case something was missed:

   [feature] temperature limits are now configurable via configuration file. The two new configuration options are: --fan-temp-hot and --fan-temp-dangerous. These options effectively override the temp limits in temp-def.h

This part of the documentation is in error, in case anyone needed to use those options they actually are:

fan-dangerous-temp and fan-hot-temp.

yes, that's the correct format (... "fan-dangerous-temp":"90", ...)

Hey dudes

LOVE Braiins OS. I am getting 15.5TH out each of my secondhand 13.5TH S9  - Whats more they are running comfortably under 79'c and under 50% fan speed. Beautiful.

However!  Anyone had this issue... ?

I installed via windows, python/SSH on a (brand new) DragonMint T1 and everything looked great!

GUI running fine.. but when trying to mine I get an error "CGminer stopped" or "CGminer keeps stopping, possibly incorrect configuration" (or something similar)

CGminer and monitor is installed, I made no modifications to the stock OS install, all tabs work etc and Pools all say they are alive.

What could be wrong?

I tried reinstalling, reverting to manufacture restoration (which does hash) and reinstalling. It is a G19 version with no SD card slot on the controller.

GUI running fine.. but when trying to mine I get an error "CGminer stopped" or "CGminer keeps stopping, possibly incorrect configuration" (or something similar)...

I got this error when the pool configuration is incorrect, mainly the worker name.

[m4acker]

I wish it was this problem. But my pools were alive and I straight copy pasted from other miners running already, incrementing the worker number.

When copy/pasting look out for an extra whitespace at the end of the text. Very often a trailing space is copied as part of the text and must be deleted from the string before it is able to be used.

Thanks yeah. I work in a tech support role and have to deal with simple user error a lot like trailing white spaces etc often. I'll do some more digging and report back if I find a cure for this CGminer stopped issue. I'm sure there are debug / system logs I can check somewhere....

[sergw]

guys, from braiins - any plans to add per chip freq-tuning?
