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

[windpath]

Great product Braiins, thank you.

Suggestion: There is no where I can find in the GUI to display the status of the supplied pools (i.e. if a pool is dead, and what pool is currently being used), it would be great to have that.

Hi,

thanks for your suggestion!

We would like to bring a new status page in the next Brains OS release.
Hopefully it will meet your expectations :-)

Have a nice day,

[sohail289]

please add a manual fan speed option also.

[braiins]

please add a manual fan speed option also.

It's also in our plan

Hi and thanks for your firmaware, I liked it a lot.

I waited a week to see if you are going to post an explanation on nick5429 post, but seems you forgot.
So can you please explain this, and is there any plans to fix it?

1) The temperature displayed (at least for my model of S9) is a complete lie. The miner (and this code comes from bitmain) tries to read both PCB and ASIC temp.  The ASIC temps are deemed unreliable by the algorithm and/or can't be read on my model, so the code basically takes the actual PCB temp reading (generally 50-65C for me) adds an arbitrary 30-35C to "fake" an estimate at the ASIC temps.

Braiins web UI displays the faked temp including the offset (~90C), bitmain stock UI (autofreq, pre-asicboost) displays the original PCB reading (~60C).

Great work on this firmware.  Moved 10 S9s over and all have been working great for 3+ weeks.  Plans to include T9s?

Hello, I just installed the latest build of braiins-os (via terminal) to my Dec 2017 batch S9s (auto tune, 13.5s).

And they are hashing OK (725 + 8.9v = ~15th), but on none of them are board temperatures being displayed/reported via your graph/web interface.

Bug?

[W15ER69]

hello, i installed braiins os by ssh 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

plz help.

Hi,

thanks for your feedback.

We are already aware of issues with temperature stats. We are currently working hard on a new release that has fixed API and overview page with realtime data and should solve these problems.

The new release should be out in couple of days.
Thanks for your patience and have a nice day,

braiins, any plans to add more details into Web-UI like bad chips, asics number, HW errors counter, board temp, pool Diff, works, accept/reject/lstime/blocks etc. ?

and also will flashing braiins fw by gui too be supported? for dummies like me...lol

Hi,

yes, definitely. We are finalizing a brand new status page with more details.

Hi,

yes, we would like to make it easier as well

If you do nothing else, please for the love of god give us back the default status page that shows if we have bad chips and the current frequency of everything, temps, fan speeds, and stale, rejected, hw error, pool status, all on one page... your interface is nice but the other information is more important, and that it all be in one place is also important..

Is there any way to see which pool is connected and mining in the current version?

[probojnik]

Hi
How can I check errors and error status of hash-board?
In my S9 13.5 one hash-board stopped working

So I've been testing out braiins for a little over a week on an S9 mining to slush pool.

After playing around with the frequencies and voltage for a while I've found 712MHz at 8.7 volts to deliver a stable 14THs, pretty good for a 13.5THs miner.



The issue I'm encountering is that the reported hash rate on the pool and the miner are very different. While the miner shows ~14THs Slush Pool is only reporting ~9.5THs.



I have other miners on the pool that are not running Braiins that report simmilar hash rates on the miner and the pool, why the discrepancy? I've exhausted my own troubleshooting options, anyone have any suggestions?

at 712 freq, you should have 15.2 Th in ideal.  for getting 14Th - 650 freq enough. try to decrease freq and increase voltage.  try 650 freq and 9.0v

I have an S9J with a bricked control board. Is there a way for me to run braiins os off of sd? I tried and no go, any help?

Never heard that someone could successfully flash the s9 miner through sd card. According to Bitmain "it cannot be done through SD card flashing".

Anyway, have you tried the method from here https://bitcointalk.org/index.php?topic=2386296.0

I'm sure you can fix this issue by following the method above.

I have not taken a close enough look. Possible eprom flash?
