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

[fanatic26_]

After editing the file CONTROL  I was able to successfully flash a controller with this firmware. The first unit i tried it on killed the controller I think, I cant get an IP out of it at all anymore but the second one worked just fine. Thankfully I have a few hundred spare controllers.

Hold down the reset button on the board like a normal hard reset. It should go through the normal hard reset process and fix what didn't go right.. That Did happen to me.

And yes. But I didn't want to be the one to be blamed for someone frying their BB

Would be nice if this could be used with the R4... Also, any plans to add asicboost?

for the hundred thousandth time ASICBOOST requires compatible HARDWARE. There is no magic software to enable it on hardware that was not designed for it.

and it is tricky to run more than 1 miner on a SC card as it will have the same MAC address and it seems that DHCP is giving all the same IP address.

also it is not working on all S9s. it worked fine on the first 2 (S9) and not properly on the 3rd which is a S9i, hashrate was rising very slow and barely reached 10,5THs. one of the hashing boards was hashing very low..

Been using it on 2 S9 for like 3 weeks, temps are below 70 (but can those numbers be trusted??)

also the fans are running slower thus the miner is quieter and the noise is at a lower pitch.

There's a way to change the Mac address in the config file if you flash the firmware via terminal. It's in the Readme about adding the address and such.
The Temps if I am reading their gits correctly is using the alternative temp via bitmain.c driver. One is temp and one is pcb. The antminer s9 normal pages, use the chip temp I believe, and slush uses the pcb temp, which is the lower of the 2 Temps that get returned. So it looks lower. But is like a normal offset of like 26 degrees I think if I remember correctly

[Breeze]

Hope they show both temp on the next release.
Mine is running nice with the SD card since couple of weeks.
Waiting for the next release with more functions before i flash it on the controller.
Keep up the good work.

If you compile the cgminer git from braiins sources, you can edit it so you can have both Temps shown. I'll see if I can find the line for the Temps. Then it's a edit on the webpage to show both.

How to backup the original firmware? I don't understand

Could I upgrade Bitmain firmware before? It is usual Antminer S9 (April batch)

From what I  can tell, cuz I didn't use the SD card img, but yes, you can change that to the Mac address of the antminer. And it should give you the correct ip.

Using the SD card version you don't need to back it up. Just set the omg up on a SD card so you can run the miner off the SD. And it doesn't touch the firmware

for the hundred thousandth time ASICBOOST requires compatible HARDWARE. There is no magic software to enable it on hardware that was not designed for it.

The Antminer S9 was always "theoretically" capable of supporting overt ASICBOOST at the hardware level. No one was able to leverage it though. They still have not succeeded.

There was a lot of talk on Reddit regarding this:

https://www.reddit.com/r/BitcoinMining/comments/8303fa/enabling_asicboost_for_antminer/

However, the possibility still exists. Check out this blog post by Braiins OS:

https://medium.com/@braiins_systems/bitmain-antminer-s9-asicboost-capability-verified-by-braiins-13-in-energy-savings-and-planned-da67c290152c

Whether they finally succeed or not is another matter.

[Apprentice]

still want to see chip temperatures.

the S9 is draining a good 6.8A at 14.6T (that was a 13.5T that was hashing at 13.1T and couldn't get it to hash higher).

Here are the steps if you have a linux computer on your network:

This is just the "Migrating from factory firmware to Braiins OS" setup from https://docs.braiins-os.org/ but instead of booting into the SD card and doing it locally, your doing it from your linux comp over the network:

I'm testing on an Antminer S9i over my network. 192.168.2.72 will my the address;

Requirements: braiins-os-firmware_zynq-am1-s9_*image*.tar.bz2
python3 python-virtualenv setuptools(18.5 or newer)to get some possible errors out of the way

ubuntu/debian flave:

Code:

apt-get install python3 python-virtualenv

CentOS/RedHat flave:

Code:

yum install python3 python-virtualenv

- Press Y to install

Now update python setuptools with pip because you likely already have python installed and some modules just need updating:

Code:

pip install --upgrade pip setuptools

Should now be ready without errors

Upload braiins-os-firmware_zynq-am1-s9_*latest*.bz2 to a folder on your box, in my case i downloaded it to /root

you can use wget, if you are using a windows pc you can upload using winscp:

Code:

wget https://feeds.braiins-os.org/braiins-os-firmware_zynq-am1-s9_2018-09-22-1-8d9b127d.tar.bz2

Now we are just following the directions on the page:

1- Unpack firmware

Code:

for i in  ./braiins-os-firmware_*.tar.bz2; do tar xvjf $i; done

/root# for i in  ./braiins-os-firmware_*.tar.bz2; do tar xvjf $i; done

2- Change to the factory transition directory;

Code:

/root # cd braiins-os-firmware_zynq-am1-s9_2018-09-22-1-8d9b127d/factory_transition/

I'll skip pasting the resulting text but just follow the instructions:

3- Next :

Code:

virtualenv --python=/usr/bin/python3 .env

4- Next :

Code:

source .env/bin/activate

5- Next :

Code:

pip install -r ./requirements.txt

you may receive a setuptools prerequisite error setuptools must be > 18.5 , this may be because this virtual environment creates a small sandbox (?) if you do get this error run try to update setuptools via pip again;

Code:

pip install --upgrade pip setuptools

and re-run:

Code:

pip install -r ./requirements.txt

6- Next :

Now i will write to one of my antminer s9i's (192.168.2.72), you will be asked for your antminers root pass

Code:

python3 upgrade2bos.py 192.168.2.72

[daniel232388]

hah as i type this Bitmain just released firmware with Overt Asicboost enabled https://blog.bitmain.com/en/new-firmware-activate-overt-asicboost-bm1387-antminer-models/?utm_source=twitter&utm_medium=social&utm_campaign=asicboost-activation-firmware

is this the firmware "Antminer-S9-LPM-20181022.tar.gz"?

[localAlien]

Can you adjust/disable the fans for immersion cooling through the Braiins OS?

[daniel232388]

anyone tried the firmware?

[rz66]

From slushpool:

Dear Miners, we strongly recommend you DON'T UPGRADE your S9 devices with the new Bitmain firmware. It is not compatible with BIP310 standard and as a result also not compatible with @slush_pool. We are working hard on providing our own fix asap and will keep you posted.
