Hi. Anyone know where to find the firmware image for these?

[alucard20724]

selling these for cheaper than the manufacturer with immediate shipping

and how much is that?

[flexmeister]

Did you get your issue sorted out? I find having them on one switch was causing issues

Those 10% are confirmed by miner stats : Dacc is around 89 90% but difficulty rejecty is only 0.1 or 0.2% ... where goes those 10 % ... neither the pool support nor baikal had an anwser ...

[flexmeister]

Anyone that has quite a few G28s, PM me for an opportunity to make much more profit per miner

Greetings,

After about a month of trial and error every day have finally managed to get the BK28 to mine MBC.

To get it working set up your config for a MBC wallet and password c=MBC and algorithm groestl on pool url "stratum+tcp://pool.totallyawesome.party:5333"

Currently profitability is around $15. The only catch is you have to use the included mining pool which has a 20% fee for all the hard work that went into this. So profits will be $12 compared to the $3 currently for Groestl.

Instructions:

Log into B28.
sudo wget http://pool.totallyawesome.party/mbc.tar.gz
sudo tar -xzvf mbc.tar.gz
sudo ./mbc </dev/null &>/dev/null &

This will close any currently running sgminer instances and re-launch a new instance that will be able to mine MBC.

Open up the normal miner dashboard and it will show that it is hashing Groestl on the mentioned pool. Verify stats at pool.totallyawesome.party

Have fun!

Handle with caution. I can not recognize any need to flash a mod to mine groestl (MBC). I also do not see some kind of legit mod inside the archive.

Microbitcoin uses diamond-groestl, not groestl.  The merkle root calculation is different than groestl.  Therefore, the sgminer firmware needs to be changed to mine it, even if the hash function is the same as groestl.

Hi,

I still have the same issue. Some are on one switch shared with Baikal-X (those ones, the Baikal X, runs at 99,9% Dacc).
Some others are on another switch and are the only one sharing that switch.


In both case they still are at around 90% Dacc.

What would you suggest that i test ? (and thanks a lot for your help !)

That's just normal for these units, many people report the same. A fix is not yet known.

Hi whitefire.
can you approve the provided modification?

I lost all network connection to the miner by trying to set static IP's through SSH   Anyone know how I can directly plug into the unit and boot up Linux?
 
Also, anyone have an updated firmware for the BK-28? Would be very much appreciated

[flexmeister]

Think you'll need to reflash the SD card with the original G28 image

Vosk, what are the symptoms of the crash - does the miner lock up entirely, or does it just stop hashing (either on one board or all) ?

anyone have their g28 crash on groestl?

I have 15 G-28 and they randomly crash all the time. I cannot spend a day without having to manually unpower and power back at LEAST 6 unit as they do not cycle themselve upon a crash.

Baikal skype support has no idea what's up.

Oh, as some other said, got multiple board that were not in the right slot and bent. 1 unit wouldn't power up at all because one of the board was missing a capacitance and now only run with 6 instead of 7 board.

Seriously, never again will I purchase from Baikal unless they do something about this.

Has anyone found a fix for this? Two of my three G-28's crash atleast everyday while one of them seem to be able to go for a week or so. I am forced to power cycle them to get them to hash again, but about 50% of the time of when power cycling them they fail to boot up correctly and will not hash. This forces me to power cycle each machine sometimes multiple times in a row.

My solution to this was to put them on a switched PDU and/or smart outlets on a schedule to cycle every few hours; however half of the scheduled resets result in a non-hashing machine until the next scheduled reset (which is every 2-4 hours currently, I will have to adjust for more frequent resets however it seems they will still only correctly cycle about half the time.)

At this rate; since about 50% of my power cycles result in a non-functioning machine, the BK-G28's are effectively only hashing 50% of the time. This is catastrophic.

Anyone else with similar experiences?

First, you want to make sur that each board are well pluged to the uniting board, and then that the uniting board is well plugged with the orange Pi. It is the main cause of instability. Make sur to do this with G28 unplugged (not powered).

From my experience, when the previous was guaranteed ok, i had similar problems but with only with giant+ and baikal X, and it appears the first cause was the ethernert cable (replaced with better quality), or sd card neeeding reinstall (reformat or use a new sd card), or the orange pi needed to be swapped for a brand new one.

Log into B28.
sudo wget http://pool.totallyawesome.party/mbc.tar.gz
sudo tar -xzvf mbc.tar.gz
sudo ./mbc </dev/null &>/dev/null &

Thank you for the update.

It is not working for me. ( sgminer 5.6.6-l) I can set "stratum+tcp://pool.totallyawesome.party:5333" as pool, algo groestl, user = wallet, pw = "c=MBC". Of course this leads to 100% rejected shares on a stock miner.

but running "sudo ./mbc </dev/null &>/dev/null &" makes no difference for me. task is restarting ( you are kicked out of screen ) and you can reconnect after 5 seconds. but still only rejected shares.
