after installing brains os, i do not see chip temps. it shows - 0 for all hashplates, anybody faced the same? btw this is s9 13.5T from apr-2017 batch.

I've restored to factory on a couple with no issues. Having one with this problem now though.

[...]

This kills the web interface but SSH is still fine. I try to run the script again and get this.

[...]

I can reboot and everything is as it was for Braiins, but can't get back to original firmware.
Not sure where to put bug reports for this but ayyyy. Here ya go.

I have the same issue, have you managed to recover it to original firmware or restore braiins os?

Hi,

I wou;d download Brain os, but i receive an error 520 on all files located in : https://feeds.braiins-os.org/

Do you have another mirror?

with the latest version you can change the MAC address and it is saving it even when you reboot. The same goes for the CGminer settings (am taking about running it from the SD card).
So you can change the MAC address and reserve an IP from the DHCP on the router.

Currently, I have three S9s that the fans are revving up and down every minute or so. All three are running off the SD image.

I only ever had this happen once before on an older S9 13.5 and just moved it down the line and set to fans 100%

Has anyone found a way to set or adjust the fans? I am hoping for an easy resolution and not have to pull them from the site.

bunch of other options and why no fan settings? is there any way to custom fan setting? im using it with sd card on my s9 13.5

Thanks for getting me looking in the right place. It seems to have been an issue with my router. The router showed the miner at the old IP. I found the miner's real address using an IP scanner, an address that didn't show up in the router, but still couldn't connect to it. Restarting the router did the trick.

is the firmware setting the "Recommended voltage" automatically?

or the voltage should be manually changed as recommended?

Hi.

If you set a certain frequency you can se a recommended voltage in the voltage-field and i believe that's the voltage Braiins sets it to.

I was confused because as I was increasing the frequency the recommended voltage dropped.

After this I set the frequency per board to the same as Bitmain's autotune set it before. The recommended voltages then were 9, 9 and 9.1. I locked the voltages to this and started to increase frequency step by step. I think this was a good basepoint.

I'm sure that the best setting is different for each miner and also dependent of if you have AsicBoost enabled or not (enabled in my case), but for me this worked out well. You can find my results earlier in this thread. There might also be a better setting for my miner, but in my case I seemed to get the best results (speed, power usage and error count taken into the calculations) when setting the same frequency on all boards and adjusting voltage until I got the same speed (+/- 100 GH/s) from each board.

Remember that overclocking is completely at your own risk which is also stated in Braiins-OS.

I tried reflashing an S9 using upgrade2bos.py. Seemed to work flawlessly - It completed by printing "Content of U-Boot configuration:", states that "Upgrade was successful!", and "Rebooting..." After quite some time I am still unable to access it via browser or SSH. It shows up on my router and is definitely drawing power.

What am I missing here? Is there a specific port?

Thanks.

Try to check if you ip has changed.

This happened to me when temporarily switching from Braiins to Autotune and S9 connected to router with DHCP enabled. When switching back to Braiins the IP also switched back.

This happened even though I had the S9:s mac-address set in uEnv.txt on SD-card.

You might also want to try to delete the history in your web-browser.

Flashed the braiins-os on some S9 for testing. First quick questions:

1) No Fan information available ?
2) Does braiins-os has emergency power off by overheat or broken fan detection ?
3) how to write braiin os to nand when already booted with sdcard ?

Thanks

Set the Mac address on your router to a static address for that miner. And try again

Static leases are maintained by a windows DHCP server in my environment. Thank you for the suggestion, I'll run with it in a couple ways and see if it alleviates the issue.

on a 13.5 machine am getting 14.6T at 695 with old firmware and 14.2 with the new firmware with AB enabled. can pump it to 15T but one of the chains is not going beyond 4.7T

chains names are not consistent. on pages it's 0-5 other 1-6

So testing on 1 machine for about 6 days now. Good start . On day 2, overclocked. Some Trial and error, got a steady 14.2 at 80 - 82 degrees (13.5 machine. usually ran about 13.6) .
Ran great and steady at 14.2 or so for several days, until last night. Then dropped to 13.4 -13.5. Machine re-starts daily. Tried resetting stock speeds and now machine is running at 12.9 or so. Will continue to play with....

So I continued trying to figure it out today and ended up with the following settings that I will keep for a while:

Frequency: 725 on all three chains.
Voltage: Chain 1: 8.9 V, chain 2: 9.1 V and chain 3: 9.2 V.
AsicBoost: enabled

Result:
All three chains hashing within 100 GH/s at around 5000 GH/s. So a total of just over 15 TH/s pulling 1440 W out of the wall. Yet to see if it's stable or not.

So after doing my calculations Bitmains LPM would be more efficient IF it would stick at 13,6 TH/s pulling 1220 W out of the wall.

Efficiency
Bitmain autotune: 13,6 THs at 1395 W = 9,75 GHs/W
Bitmain LPM: 13,6 THs at 1220 W = 11,06 GHs/W but drops after a few hours
Braiins OS: 15 THs at 1440 W = 10,42 GHs/W (Obviously I probably could get at least the same results as the LPM with Braiins, but where's the fun and the balls in that? Grin

)

Please correct me if I got something wrong.

This would have been impossible with the other dev free solutions in this forum as my hashing chains are so different. With the possibility to set the frequency and voltage separately for each chain I think I got a pretty good result with a miner not that good.

So a big thanks to the Braiins-team.

Has anyone had an issue with Braiins-OS on 14TH S9i's where they reboot every 30 minutes or so consistently. I have units with both sd cards and flashed nand, no change. Not sure if this is isolated to the S9i batch I have, but would like to hear if anyone has had this issue.

*EDIT* Figured this out, you have to create a password within the braiins web interface. I guess that's okay, but.

Does it say 'only Slushpool'? No.
Ergo, works with ANY pool that supports AB such as Kano.is, -ck's solo and his regular pool, and others.

Will this OS with LPM and/or the newest 1023 Bitmain firmware with LPM work to mine on NiceHash? Could one of you who have changed over to the LPM firmwares/OS's test this to see?

Thanks!

Just got a partial answer. NiceHash just made an announcement that they now support AsicBoost mining! Yeah, but, I'm still interested if the Braiins OS will mine with NiceHash and other pools - or this only for SlushPool?

So my normal temps are between 75-80. I flashed this and everything shot up to 103-105. I tried taking off all boosts and click speeds and no luck. I just flashed back to stock and it's all fine. Any ideas? This was an s9i, and it also was only hashing like 13 while overheating.
