Just had a temp sensor jump to 176C , pretty sure it is an error. Shuts down cgminer.
Guess I'll go with fixed speed on that one.

I have seen that one before. Did you not get funny hashrates in one of the chains too?

I know if I boot from SD card and then try to change DHCP to STATIC and set an IP address it does not take if I reboot into the SD card again. I had to boot into SD, find the DHCP IP, login and flash SD to NAND using GUI, then boot into NAND, THEN set static IP.

thanks for your reply, I will try to connect device directly to pc and I’ll inform you about result

[...]

and yes I did it using sd card and permanently install bOS to NAND (both from web interface and ssh) and both of them completely successful in logs message! but when I changed the jumper to nand the device can not give IP address. totally it seems couldn’t boot from nand.

Did you manage to fix the problem?

end of /etc/cgminer.conf

Code:

,"api-listen":true,"multi-version":"4","fan-dangerous-temp":"109"}

Make it look like this

Code:

,"api-listen":true,"multi-version":"4","fan-dangerous-temp":"109","no-sensor-scan":true}

Using vi /etc/cgminer.conf is one big line.

can anyone help me where to do this (--no-sensor-scan)? im really noob.

Could someone be so kind as to clarify what exactly "per chip frequency calibration for Antminer S9" means? How does this work? Having trouble finding resources to learn more about this. Thank you.

Did get 6/5 OS to boot from SD on T9+, will not recognize hash boards. Sad

System.log just spins.

Did you flash from SD to NAND image 6/5 version?
...
Guess I'll boot from SD.

This also resulted in failure (doesn't boot).

I know the T9+ has 3 small and 3 big hashboard connectors. T9+ uses the big connectors only. Thought I could install a running s9 flashed controller
but hash connectors are bigger on T9+.
I'm going to play with it.
I only have 2 T9+, would really rather run braiins on them.
Guess I'll boot from SD.

I hope my discoveries are helpful to others.

Thanks.

Not officially, and my last attempt resulted in failure...

I have found that if I install an xilinx card in an older s9 to install brains the holes don't match up.
This causes the ipreporter button (on left) to be pushed in all the time.
When that happens the boot cycles constantly.
I take off the little front plate on the controller board carrier. Then it will boot successfully.

A corrupt or missing cgminer.conf can cause issues as well, won't start cgminer.

I have had ssh access not available when trying to fix the cgminer.conf.
Had to enable DROPBEAR through the gui to get ssh access.

Another anomaly- running Kaspersky on PC that is using the gui configuration page.
Kaspersky blocks, so you cannot change anything on the configuration page. (pools!)
I just disable Kasperky and then fix the configuration page, then enable Kaspersky.

Running on 100+ miners, VERY STABLE.

With the 6/5 Braiins firmware pushing the image to the SD card , changing the jumper to boot from SD,
I can use the GUI from the SD card to flash the NAND and fix cgminer.conf missing, and other problems.
The GUI only has the flash option on the 6/5 firmware running from the SD using the new image.

I can pretty much mix and match any s9 hashboards with Braiins. Mixed S9 with T9 boards also(s9 form factor)
Just a wonderful piece of software.

Does braiins work on T9+ yet?
Thanks.

Well thats very strange, try finding its IP the way i suggested (you can leave the hash boards disconnected while this completes). Or try a reset:

Quote from: https://docs.braiins-os.org/#reset-to-initial-braiins-os-version

Reset to initial Braiins OS version

Uninstall the current firmware package to downgrade your firmware to the version which was initially installed when replacing the stock firmware.

$ opkg remove firmware

In addition to the above, reseting to initial Braiins OS version can also be initiated as follows:

IP SET button - hold it for 10s until red LED flashes
SD card - first partition with FAT contains file uEnv.txt with a line factory_reset=yes
miner utility - call miner factory_reset from the miner’s command line

If you boot using the sd card, you can also permanently install Braiins OS to the nand controller flash storage, this would also get rid of the evil 2019 firmware.

Is IP SET button is same IP REPORTER button? If it is I have no luck to get recovery mode.
and at last no new IP listed in router dhcp list. and scanning network with arp also unsuccessful.

Is this maybe happend beacuse of new antminer s9j frimware?

I would suggest you connect a pc or laptop directly to the miner, and perform an ip scan using a tool such as angry ip or nmap.

But, for your information and the people reading this thread:

The IP report button works if you run discover.py

If you boot using the sd card, you can also permanently install Braiins OS to the nand controller flash storage, this would also get rid of the evil 2019 firmware.

Yes, when I boot from SD every thing is OK! It is weird, because after installing to nand installation log’s message was successfully complete but booting from nand has no ip! green led blinking fast and red led blinking slow.

IMO just run from SD on those 3 miners and flash the NAND back to factory. worst case you can pull the SD and be back to normal.

Hello I have couple of Antminer S9 and some of them have issues time to time. I wanna ask 2 questions here related to Braiins OS.
1- Lets say I have one or more faulty chips in a hashboard(Finds 40 ASIC instead of 63). With Bitmain firmware It wont hash with that hashboard and even the whole device stops hashing. With Braiins OS I will have same issue? Because It would be great if it just continue hashing with 1/2 rate while other 2 hashboards on full power.

It will still mine even you only have 40 good ASIC but hashrate might drop without any issue.

Quote from: eotrix on June 18, 2019, 12:46:22 PM

2- Is it safe to run braiins OS in long term? Also is it safe to boost like 500 GH/S for each devices(Not much) is safe for long term?

Yes, it is. There are many users use this OS to troubleshoot or to use it permanently and I think it is safe to run this OS for the long term never heard any complaints that Braiin OS will harm your miner. I think it depends on you how you maintain your miner. Just make sure that your fan is running fine and enough to cool down your miner.

Have you tried sd-card boot after problem showed up?

From Braiins Docs:

Quote from: Braiins

Recovery Mode
Users don’t typically have to enter recovery mode while using Braiins OS in a standard way. The restore2factory.py downgrade process uses it to restore the original factory firmware from the manufacturer. It can also be useful when repairing/investigating the currently installed system.

The recovery mode can be invoked in different ways:

IP SET button - hold it for 3s until green LED flashes
SD card - first partition with FAT contains file uEnv.txt with a line recovery=yes
miner utility - call miner run_recovery from the miner’s command line

Also:

Quote from: Braiins

Recovering Bricked (Unbootable) Devices Using SD Card
If anything goes wrong and your device seems unbootable, you can use the previously created SD card image to recover original firmware from the manufacturer:

Follow the steps in Creating Bootable SD Card Image to boot the device
Run (on Windows, use python command instead of python3):

Code:

cd braiins-os_am1-s9_ssh_VERSION
python3 restore2factory.py backup/2ce9c4aab53c-2018-09-19/ your-miner-hostname-or-ip
