Antminer S9 firmware build, overclock, change voltage, disable fan check - Tutorial

[@JavadFarzin]

آفرین The first in the world👏👏 T17 42 th (Changing the ASIC frequency and voltage ) Thanks

[@_Paxton]

Got this running on the new to date S9 firmware. Though I have alot of machines on Braiins-OS. Only config I'd like to add on top of Braiins is the fan check disable. I have a submersion project underway and am working with stability in clocks among other things across various firmwares. I was curious if there's a shortcut to implement the disable fan check "easily" (use that loosely). Thanks.

[@AnonyMous-oj7pr]

Nice mate, Hope to see a Firmware update for it soon !

[@billycassanova8117]

thanx dude, it help my fan trouble :)

Just heads up for ppl - when copying two lines to paste into Makefile make sure there are no additional spaces copied - just had compile error and figured it was an extra space after "XILINX_OTHER_LIB_BASE_PATH=$(CURDIR)/build-tools/prebuilt-libz/linux-armhf" line

Hi there, Is there any possible to run a python script on antminer ? Please response

[@hamedhossani8481]

Is it possible to use s9 for mining ltc with scrypt algorithm? Why not? Is Bm1397 chipset mine btc? If we change program in controller, answer is No too?

Hello Alex, I have Antminer T17e , is there way to build bmminer binary for this one ?

[@francescocmazza]

Hello, thank you for your video. I want to edit existing bmminer binaries. I understand I need a decompiler. What decompiler do you suggest I can try to work with? Thank you very much Friend

[@tesseract8412]

Hi guys. I am a newbie in this staff. Could you please explain me couple of things: 1) As i understand, the original OS in ASIC is argstorm and this is the only thing we need to flush into the board (so the firmware for ASIC actually is the only OS). "bmminer" is a just binary that OS invokes automatically and actually this is the thing that does mining. am i right? 2) What's the difference between bmminer and cgminer, is cgminer a part of bmminer? I encountered both and don't understand it enough. Thank you in advance!

[@gapperx9068]

Thanks Alex for such a gr8 video. Have you had time to engineer for L3+ or L3++?

[@hamedhossani8481]

i have same request.

[@СергейКапкаев-т9з]

Wow. Thx. Great job! Did you compile single-board-test ? Have a lot issues with cross compile method... unfortunatly

[@Alexander1560]

Hi, you are welcome! I did not find the need to try to compile single-board-test so far

[@hanxiao824]

I encountered a problem while modifying the source code. I don't know how to enable the asicboost function with the source code of bmminer-mix in github. Could you please so kind to make a tutorial or give me some introduction information. Thx!

[@Alexander1560]

Hi, I am no longer working on that project. You cannot enable asicboost from that source code, you must add more code to it to have asicboost working.

[@Eric-the-wise]

can this be done with an x3?

[@pavlob2]

All of the links in the description were substituted with youtube forward... Is there a way to get those? Thanks

[@SargesX]

@Alexander1560 Good afternoon! Do you have a very interesting project, please tell me how to add to the firmware the possibility of automatically obtaining "x%" for the development of the firmware?

[@Alexander1560]

Hi, we work on our own firmware version which we license to big farms for now. In the future we may make a version open for public, but now we work with farms with 1000 or more machines to tune. We do advanced power consuming testing, temperature probing, hardware failure measurements, this is why we don't release a public version yet, as there are a lot of versions which perform differently when overclocked. We cannot provide any more guidance in coding, I would advise looking for a C++ programmer which can use this video to build the firmware and can modify the source code.

[@SargesX]

I also have more than 1,000 machines, I only ask a little help. between us there is no competition. Please help :)

[@Alexander1560]

To have percentage you have 2 options. You create an event inside linux to reboot and set pool to your pool every day into config and mine xtime for you, or you modify bmminer to switch pool after a certain uptime and you reset the counter everyday. It's not easy to program and I cannot share this code as there's a lot of things to cover and tests which must be done. One time on an early prototype, the miners would get stuck on mining just for us or just for the client, so we used the second approach. There's a 3rd approach that we are considering for the future, but is more complex. It requires a management software which will monitor the machines and switch pool automatically without rebooting and loosing 2-3 minutes for each machine. For 1 machine is not much, but for a 1000 machines you loose 50 hours of mining each time. We can do all this work for you if you are interested, we charge fix amount per license. In case you are interested, let me know.

[@rb.4559]

hello I have a firmware with pool fees that are not seen you can edit the firmware to remove them ????? I would send the firmware here!

[@Alexander1560]

Hi, get in touch on discord and we can talk there... it depends how much you're willing to pay for this.. if it's for a couple of machines, then it's not worth the effort, so don't bother. discord.gg/JKFzRbE

[@davilezve]

Hi alex, how are you? can we modify the voltage on bbminer? I have some t9+ and it is a different firmware than t9. also, would you help me to make a custom firmware that allow to modified voltage and keep with the original firmware?

[@vistanationrockafellaz]

Hope some one can recompile upper version asic then s9 which support 42th 53th 90th to mine scrypt

[@НикитаГармаш-ъ3ц]

Thank you very much for your tutorial! One question if you allow! Is there any way to make a firmware file to overlock via "upgrade" option? I got a lot of machines, so it's complicated to do all stuff with each. Thank you in advance!

[@Alexander1560]

Hi, It's possible to do, but I did not made a video yet. I would advise looking into batch scripting as you could achieve this with python or other programming, to connect via ssh to the machine and copy the files automatically

[@НикитаГармаш-ъ3ц]

I followed your tutorial step by step and got it working, but I'm not a genius like you, it's impossible for me to do what you described :) Thank you again, your work is great.

[@lartg.7016]

Hi, very nice job. But is there any way to reconfigure(decompile) an existing bmminer. If i understand your tutorial right, i compile an complete new bmminer. But i still have an working system with an individual firmware on my s9 (not stock firmware) and i want to change some small thinks to make it better working for me. Please give me some hints how to do that. thanks

[@Alexander1560]

Hi, sorry, cannot really help on that, once is compiled is very hard to change things, it will take weeks to try to figure which bytes to change

Hi Alex, Tnx for the great video, I’m not a programmer, but probably I’ll be able to locate the file, change the line, is it possible to do that without making new build of the firmware, I want to change the fans check settings only, without the overclocking part.

[@justscripture1384]

Apologies for repeating the question, I have to buy the firmware I think. Can you roll back the original firmware via update, if there are problems?

thx for the great tutorial, thing is, i followed step by step and it works! partially. It did bypass the fan detection but one of my hashboard is dropped. In the kernel log it says "chain[J6] has 0 asics" while J7 and J8 have 63 asics. So i only have 2 hashboards that are running right now. Please help.

[@Alexander1560]

Hi Kevin, is the board working with the old firmware? Are all three boards same version ? if you mix them then some might not get recognized. Another option, you overclocked too much with poor cooling and the board died. This is the down side of overclocking, you must provide proper cooling to make it work.

[@kevinhuang2691]

Hi alex, i didn't OC tho, all i needed was to disable the fan detection and thats the only thing i modified because one of the fan connector on the control board failed so I connect the fan directly to the PSU and it wouldnt mine. The boards were all good using official FW, turned out to be the modded code didnt work after all, the 2 working boards worked for several mins and died, no hashrate at all in the end. I gave up planing to just replace the control board.

[@Alexander1560]

[@Alexander1560]

Hi, can you tell me the version of the boards and the miner version? For this you need to check the sticker actually placed on the hashing boards. I believe those contain a different temp sensor which is not included in the firmware released on git. Some users claimed to have issues with the march 2018 batch. If I could get my hands on such a board I could bebug more and find a solution or contact bitmain to ask for the missing code (I already contacted them but they said all the code is already on git, without proof in my hand I cannot argue with that), but without a board that I can't do anything.

Hi Sir, very appreciate of this video, but is too complicated. can u suggest how to disable fan check by just using winscp modify the bmminer.conf file? Bcos my control board keep fail 1 of the fan, but both the fan are new. and is too costly to repair the control board, hope you can help pls. Thank you sincerely!

[@Alexander1560]

Hi Darryl, unfortunately there's no simple way for this. I am releasing a new firmware soon which will allow disabling fan check. Is going to be paid version of the firmware so I am not sure how hepful it will be to you, or you can use the free version which is going to mine 1% for development costs. Another solution for you will be to purchase a NE555 square wave generator, which is 2-3 bucks and set it up on the fan PWM pin to fool the board... And I think another one which could be better for you, is to link the Yellow pin, which is pin 2 (left to right) between the fan ports on the board. In this way the remained fan will feed PWM to both fans. Let me know if it worked.

The asics are made for SHA256 in case of S9, so I would say not. We did not try, but it would be a waste of resources to try to experience with this without the support of the people which made the ASICS.
