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

[Artemis3]

Can you give us install steps for the "alternative image flashable via Antminer web interface"?  That would be greatly appreciated.

If you own an S9:

• Download https://feeds.braiins-os.org/braiins-os_am1-s9_web_2018-11-27-0-c34516b0.tar.gz

In the Antminer web UI...

• System -> Upgrade -> Flash new firmware image.

You won't get a backup of the factory firmware if you use this method...

To use the other method you don't need any "linux skills", you only need python installed, as the instructions clearly indicate here:
https://docs.braiins-os.org/#phase-2-permanently-migrating-from-factory-firmware-to-braiins-os

IIRC you will get a new mac address so your devices will probably need to be reconfigured for network again, and you might need to scan your network to find them again. No, the Bitmain tool won't work anymore, you need another network scanner (or check your router dhcp server). So consider doing this on site if you are not confident.

Is there way to retain the current MAC address of the units when upgrading directly without SD card step?

UPDATE:  The MAC address stays the same; but DHCP server of my router assigns the machine a new IP.  The hostname is the same 'antMiner'; anyone come up with a solution where it will connect to the network and bind to the same IP?  (Other than assigning static IPs via the router)

Thank you for releasing this software.  The installation was well-documented and easy to follow.  I'm getting the same hash rate with 1 amp less of input power.

And thanks Bitmain... for using an unfair advantage.

The miner status is not visible........although the miner is working fine.

What can be done to resolve the following ?

Miner Status
API connection status: Not connected

Is the miner hashing pool side?

[rahuldel]

Yes the miner is working fine pool side.

I am using a SDCard and did a fresh firmware and have tried two different cards but the same results, the old firmware works fine.

Only thing is it is not showing the miner screen and it is saying

Miner Status
API connection status: Not connected

[score1more]

I've found that the API crashes if you leave the miner status page up in your browser.  I've stopped leaving the page open and only check it periodically.  Seems to help.

If you go to Services > Miner and click save/apply.  It'll restart the miner and the API used by the monitor page.

hello, i installed braiins os by web on s9 13.5 all good, but when i go to cgminer, i have error

Code:

/usr/lib/lua/luci/dispatcher.lua:460: Failed to execute cbi dispatcher target for entry '/admin/services/cgminer'.
The called action terminated with an exception:
/usr/lib/lua/luci/model/cbi/cgminer.lua:297: default configuration not available, create /etc/cgminer.conf

How can i fix?
Thanks

I have experienced that one before...
Try removing the package firmware from the web ui or from ssh with the command opkg remove firmware.

[balla69]

Thanks, now it's started, but i don't like.... only 13 Th/s with 1200w
How can i install the bitmain firmware?

try to increase voltage on all boards. fe for freq 650 (14Th) it should be 8.8 volt.

[balla69]

Yes, but i wish to optimize the efficiency, with bitmain firmware i mine 9,3 Th/s with 706W eff. 0,76.
The difficult is come back to bitmain firmware...
I don't have a backup.... how can i fix this?
I've another s9 for make the backup, but there's the instruction only for create a backup without install ?

if you dont have backup - then you need to use SD card to boot asic and flash bitmain fw.

I've prepare a ssd with brains firmware,
Can i put the firmware bitmain in the ssd, change the switch for start from ssd, start and flash the bitmain firmware?
Or
I must be install the firmware braiins in another s9 from sd card, after restore the save firmware and after restore also into the first s9?

yep

Hi all.

I tried Wolfram in my S9 earlier (and loved it), but I've now been offline for a while due to low bitcoin price.

Yesterday however I jumped back in after putting Cobalt (love it even more) on both my own and my friends SD-card.

Long story short:

My S9
- 13.5 THs February 2018 batch
- Firmware: November 2017 autofrequency + November 2018 LPM
- Running Cobalt from SD-card
- Works like a charm

My friends S9
- 13.5 THs older batch (not sure how old, but newer than C5 control board)
- Firmware: November 2017 autofrequency + November 2018 LPM
- Running Cobalt from SD-card
- No temp-readings and fans running full speed. Otherwise works like a charm.

So any solution to this yet?

BR.

I've create an sd card with Etcher and i put the original bios (Antminer-S9-all-201812051512-autofreq-user-Update2UBI-NF.tar.gz) into the sd card, switch jumper for start from sd and run the s9.
I've download the ssh version and type this command from terminal.
Where's the error?

Code:

Did you run (linux):

Code:

cd braiins-os_am1-s9_ssh_VERSION
virtualenv --python=/usr/bin/python3 .env
source .env/bin/activate
pip install -r ./requirements.txt

That is what fixed that error for me and was the recommendation from Braiins support. Seems you need to be using virtualenv and install everything in requirements.txt so that you have a proper python3 environment.

this seems odd to me, running on default settings and lpm off:

voltage and frequency seem off:8.9V and  650MHZ (when should be 630MHZ), temperatures are high
and also, the hash rate on overclock doesn't get reported  pool-side to be like the S9 reports it

I'd drop those volts, my lord. I can run 800mhz at 8.8v with BARELY any he errors. For those low frequencies I'd drop the volts to 8.4 or 8.5 and then, your heat will drop. Turn lpm on. And you will see the advantages.

You're going to burn up your hashboards with that high volts and low frequencies.
