Yes, the principal could be the same, but It would be better if Bitmain let issue a v1.91 service guide not only the basic tutorial how to realize wich board is wrong and push the chips with you finger ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) . I havent see the S1 Circuit diagram yet ,could you be so kind and send me a link about it (I'm sercing about 2 days for some miner circuit diagram without any luck ![Sad](https://bitcointalk.org/Smileys/default/sad.gif) . This will be a treasure for me cause it helps me understand this architectura. ) I can see the clock and the dates with my scope, but that is the status (I push evry chip hard with my finger, I promise ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) ): https://drive.google.com/file/d/0B26YInue5gCgSzFRVjIxeDBjaHc/view?usp=sharingAfter starting evry ASIC is 'O' but makes mistakes, after a while its rezognizing the bad Asics and change the first six status for 'x' and only hash ~450ghs. I'm wondering how have to use the test pin on the ASICs. But is think it is only usable in a sepcial test cradle. Case I feel the power in myself to solder them out, but I dont sure about the ASICs problem. I suppose that the first 2 digit is refering to the middle chips of the top level. Here is a link to the S1 Circuit Diagram https://github.com/AntMiner/AntGen1/tree/master/PCBIt is of course quite different to the S5 in that it is not a string design but uses Buck Converters for the Core Voltage, however if you also download the BM1380 Manual to compare with the BM1384, it does help you understand how the data signals are strung together, oscillator etc. My limited experience is that so long as the 14V up converter is ok, the 1.8V IO voltage is ok on each chip & the oscillator is running then if the board is not hashing it's almost certainly a faulty ASIC that needs to be removed & replaced with a salvaged one. Rich THANK YOU!!!!! ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) Extremly good material ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) ! Maybe the ASIC are good, cause while I'm testing-restarting-measuring again and again that happened ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) : https://drive.google.com/file/d/0B26YInue5gCgWE1seEZFVTl6NFE/view?usp=sharingIt was very interesting couse this test least at ~6 hours and I measured several time the step up voltage output after the diode, and there was randomly voltages between 12.41-14.1, I thought maybe my new scope not perfectly calibrated so I dont car about it. And before the burning I watch the PWM signal by the way and it was totally different from a perfect board. But the board was hashing with 24 chips so I left running and thinking 1 hours ago I smellt the smoke ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) . I'll change the burnt parts with a step up modul (~5 USD) and I hope the ASICs are OK. I'll drow the interesting PWM signal, because - in my opininon - that signal form could predict the burning. (I forgat to save so I'll draw by pencil ![Sad](https://bitcointalk.org/Smileys/default/sad.gif) ) did this end up working for you? very curious.

Does anyone have an experience on installing any additional linux programs on the BBB sd card?
What are you wanting to add to it? I mean there are some who have done custom firmware out there like smit. But I'm not sure what else you would want to be installing. I've had some trouble with the miner locking up when changing the configuration on my S4. I wanted to install this, https://github.com/haakonnessjoen/MAC-Telnetit would enable me to connect to another device on layer 2(which is still active when the miner locks up). I am able to SSH into the device but it doesn't even allow any of the software to be upgraded. I'm assuming this is a security feature since upgrading could cause incompatibilities.

I want to start a rig with an S5, but my dad wants to know more about security issues with our home network. Does setting up a rig risk people getting access to our home network through the miner? And does the block have to get sent by a server that has access to our network or is it just being sent to the S5? I need to know more before I start.
I huh.. What? ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif) Everything goes through your router, so its your router's security you should be looking at. The miner is behind your router, just like your computer, so its not any different than any other device. The miner can't connect access your stuff unless you hack it in and even then, its not like its RDP. There's very limited access through the webgui. And all the work your S5 will produce will be sent to a pool (hopefully). No block is sent to a S5 or anything of the sort in the first place. If you come up with direct questions i or someone else will give you a direct answer. Also Stock S5 is LOUD. for all intents and purposes no the antminer s5 presents no extra security risk than you already had. I had a bunch extra written about firewalls but decided not to post. If you have any additional questions please post.

im doing something similar on a raspberry. I'm getting a weird error.
Its giving me this.
Bitmain detect (1:19) failed to initialise (incorrect dev ice?)
and no devices detected.
I built CGminer from the github repo.
any suggestions would be great.

I am also looking for ears.

just wanted to let everyone know that for a second time I cleaned all the contacts on my S4, completely disassembled it. Re assembled it and it is now working.

having some issues with an antminer s4 https://i.imgur.com/mm4mS2r.png https://i.imgur.com/bWiB9Ce.pngso I pretty much figured out that I have a bad IO board by putting in a good working one into this miner from another working miner. I am having trouble locating anything on fixing or replacing this board. Anyone have any insight on this? Your pics lack the asic status. Are all asics showing o's, any - or x's. I do believe there is an updated firmware version you could upload to the S4. My only troubles I had pointed to the psu which can easily be the cause of everything. What does the front panel screen show it hashing at? I would like to see more aswell. Please share status screens. I have never seen someone stack like that. It's unique to say the least. But amazing if that works with that setup. Are you running downclocked or standard freqs? Basically there is nothing more to see, Below what that page should be is the board status. There is nothing that shows up below that. the results I am getting are the same results that would happen if you unplugged the ASICs from the controller board. the only thing that appears to be working is the BB board. any comments or suggestions are helpful.

Otherwise maybe look for people here on this forum with a broken one to sell.. I have tried bitmain. They went through some simple troubleshooting then told me im basically SOL.

Looking for a Antminer s4 IO board as mine has gone bad.
