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

[Artemis3]

We are designing a new mining protocol, Stratum v2, with the aim of addressing all the major issues of the current one. To provide a complete mining stack — open-source and compatible throughout — we have also taken a big step and started designing the new mining software in Rust language.

Now, we’re almost done with the design and would like to invite you all to participate in our effort to create this open standard. We’d be delighted to listen to your needs to find out what features you’d like to see in the new mining package.

Thank you for this announcement. Can you (or slush) please make an official Stratum v2 discussion thread?

In the Pools section, is the Stratum discussion protocol thread, and the [ANN] Stratum mining protocol - ASIC ready thread.

It would really be nice to see "Best Share" added to the Miner Status page. Do you have any info on when that might be added?
  
In the mean time, is there a way I can add that value myself by digging into and editing the html/config files?

Thank you.

Any solution for Braiins OS not displaying temp status?  Antminer S9
Factory firmwares work fine.

For the life of me, I cannot figure out how to access /etc/cgminer.conf to apply settings. I've looked all over the internet, setup the SSH using Putty and cant access it.

Can someone explain how I get into the config file?

You connect to the miner using its IP with the ssh client. Default user and password is root/root or root no password iirc. Once logged in its simply a matter of editing the text file. Normally this would be done with the vi editor, like this:

vi /etc/cgminer.conf

editing

In order to edit the file, you have to be in insert mode. Press [i] or [a].

exiting vi

In order to get out of vi, you have to be in command mode. Press [Esc] (the escape key). Then issue one of the following commands:

• :w to write the current file to disc, this will overwrite the old file
• :q to quit without writing
• :wq! to (forcefully) write to disk and then quit vi

Or its possible to use a friendlier text editor, by doing:

opkg update && opkg install nano && nano /etc/cgminer.conf

Oh, golden. That's what I needed. Thanks.

Code:

/usr/lib/lua/luci/model/cbi/cgminer.lua:297: default configuration not available, create /etc/cgminer.conf

How can i fix?

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

Thanks. I tried your solution and it works but the problem is this error appears periodically. Does anyone know why?

[Artemis3]

Well i have only experienced that a few times after installing it. Are you still needing to do this periodically even when using the latest version? It is probably a bug but I'm not sure what exactly triggers it.

I guess you could try changing the permissions to the file (when its there and working) so that it becomes read only like: chmod ugo-w /etc/cgminer.conf and see if it makes a difference. It shouldn't be disappearing or changing its size to 0 bytes on its own...

Hi, braiin os cobalt it's fantastic!!!!!
but how can i set a timer ( 5-10 sec) for the start cgminer?

Bravo. Neat hack
Yes I'm still getting this error even I'm in the latest version. I've reported it. waiting for someone to fix the bug.

any chance to make a classic firmware for easy deployment ?

It clear by now that most of S9 work very well with this firmware

[balla69]

Hi, the lastest version don't connect to the pool ....... someone have the link on the past web version?

The only way I have installed is by using the braiins web image using the dec 5 s9 GUI
Running 100 s9 in a modified 20 ft shipping container, all modified to braiins now.
Switched all my s9 550 and 600 fixed mhz controllers to xilinx boards.

You've the web image of 5 december?
can you post the image or link?
Thanks

And what do you mean by that? Web version can be installed easily using the web ui update firmware button. This only works with factory firmware from 2018 or earlier, because manufacturer decided to lock the miners in 2019, and requires one of the different methods for unlocking first.

Mass deployment can be done by using a python script. For automated post configuration (stage3) you need to use the earlier version from may because of bug.

Yes, but when connect to the pool........

otherwise .......it's 1400w go to fly........

my conclusion i return to bitmain FW it's impossible work with this braiins firmware, everytime don't connect to the pool....... 1400w to the wind....

[ne4d]

how can i run quota on this firmware? if i change in /etc/cgminer.conf

Code:

"url":"poola:porta"

to

Code:

"quota":"2;"poola:porta"

lua stop miner, icant run it.

Good riddance. But others think otherwise. You may have a problem, but whatever that problem is you don't care. Your statement is simply a lie, no one forces you to use it, unlike the manufacturer...

[balla69]

but I don't give up, I have to make it work ... I like braiins fw too much, I would have found an alternative solution using the fw bitmain, but it's still a worse solution.
I've see everytime the file cgminer.conf but i don't see error.....
I think someone tell me a solution, surely there's other person who have this problem.......

Try ckpool (no register needed) and see if its working there. And tell us what pool it doesn't work with.

I've tried, i connect to ckpool.org but my problem is not the pool destination, i've tried with slushpool,zpool and multipool, sometimes connect....
Now i've copy braiins with dd into tf card, insert into the s9, copy into the nand ( my control board is xilix )
I set passwd, hostname and pool (only one, the ckpool " depool.ckpool.org:3333 " without stratum+tcp:// )
i start and work......
i power off and power on and work.
another time power off and power on and don't connect
if another time power off and power on and don't connect
if another time power off and power on and don't connect
says:

Code:

API connection status: CGMiner is trying to start but keeps restarting, maybe wrong configuration?

Last cgminer quit reason: No servers could be used! Exiting. (0:11:17, clear reason)

this's my cgminer.conf (who don't start)

Code:

{"bitmain-use-vil":true,"api-port":"4028","api-allow":"W:0\/0","bitmain-voltage":",,,,,","config-format-revision":"1","bitmain-freq":",,,,,","no-pre-heat":true,"api-listen":true,"multi-version":"4","pools":[{"_id":"1","url":"depool.ckpool.org:3333","pass":"x","user":"1NjwuT6NaWmQb7aMPGcYPQj97sQTz4nkA7"}]}

i've tried also with the 443 port but nothing change.
i've tried also add at the pool address the prefix "stratum+tcp://" but nothing.
How can i fix? i don't understand where's my problem...... help.....


Hi, i think i solved the problem.
i must be put the "Use custom DNS servers"
now working......

but IPv4 broadcast must be fill or not? i'm not fill..... i don't know what write.....
