So having read through the guide on how to get this os running on the T1, it would seem that some assumptions are made about the experience of the user. If possible, some pictures/more details about jumpers on the board and perhaps some more details on the necessary Linux commands might increase uptake among users.

[sarcheer]

So I went ahead and attempted this OS install.

1st problem: quick guide is not very descriptive! For instance, the requirement to get the control board on the T1 to recognize your SD card requires you to adjust the jumpers on the control board. No guide is given on this besides J1 0 1. I removed the control board from my T1 to get a good look at the jumpers (had to try and find them as no guidance was given on where they were on the board). Upon finding them I had no idea what to do from there or even how to adjust it to make its status 0 1. This is could simply be from my lack of hardware experience.

2nd problem: There is no SD card reader on the T1 control board. From what I can gather from the quick guide, this OS install is predicated upon using the SD card slot. So this is a hard stop and I'm not sure how to proceed.

Can the Braiins team please provide more detailed instructions, like a video perhaps, on the complete, step-by-step process to get the Braiins OS installed on our machines?

I am able to get an s9 to boot from the SD card but the python script that is supposed to install the OS to the controller itself is completely broken and doesnt work.

It just pukes out garbage when following the instructions to the letter:

Thanks Braiins. Any plans on using a different bitstream than the one that is on the S9.

Yeah, this isn't going to flash easily on production T1's since those don't have SD card slots.

It's awesome! I have 60 L3+/++ and can help with alpha test, if you need, I'm just burning with impatience. It works only with slushpool, or with any?
What's about changes in work S9 on this firmware? You can setting hashrate control, autoreboot and any monitoring services on each piece and stop use awesome miner?

[grinbuck]

It is developed by us - Braiins, the company responsible for Slush Pool since 2013.

Um... a bit confused here. The link from slushpool.com (see bottom of page) to it's maintainer Braiinz is to http://www.braiins.cz/.
You're providing an entirely new domain - braiins-os.org - and that too from a newbie account.

How do users trust that you're actually THE Braiinz that's maintaining SlushPool? Maybe a linkback from http://www.braiins.cz/ would help?

Frankly, with the number of scams going around, I would seriously think twice about installing non verified firmware, from a new source, on my antminers. Been bitten once already.

EDIT: The site is genuine. There's a press release on SlushPool as mentioned by @sarcheer a few posts down.

[vincl]

someone sccessfully installed it? i copied the image on sd card but s9 wont boot from it. how to boot from sd?

how to change jumpers? which jumpers exactly?

You dont have to install it, you just put it on an SD card and you can test it in whatever sandbox you would like to use.

Braiinz is the company that runs slushpool.....Braiinz OS is just a product they have put out. Is it really that confusing? Many many companies have a corporate website that is different from the website they offer products through.

I don't doubt that they are the same company, but I think grinbucks point is how can we be sure its actually the same company.

We can be sure it is the same company through a number of methods:

1.) There is a press release announcing the release of Braiins OS on the SlushPool website.

2.) The OS release is signed by a GPG key found on the SlushPool website.

Given these factors I would say that yes, it is the same company behind both SlushPool and Braiins-OS.

Thanks for the info @sarcheer. I stand corrected. Here's a link to the press release on SlushPool in case someone wants to review it:

Seems like a great idea, I'll post my results tonight! Thanks

Saw mention of this working only on S9i, not S9.  Think I’ll wait until this is available as a standard firmware u/g - not hassle w/SD boot.

Well they're advertising it as working on the T1, but the T1 has no SD card slot! So I guess I am in the same boat.

Maybe the Braiins team will address this thread at some point

after running on my S9 13.5 TH, it does not show temperatures, is there any solution to this problem?

how did you manage to boot from sdcard?

[Shad0wSmurf]

So, I flashed the S9 firmware to my s9 13.5. After a while of waiting and beep boop beeps, it's up and running.

https://imgur.com/a/x3yUiVR

I kinda wish it had a cleaner ui, the graph is great, except, I would like a dashboard similar to antminer. Just because I have to keep switching between tabs and then forgetting which tab is what. Maybe I will begin to like it.

Frequency seems alittle wonky, at 743 I am getting less than I should, but, Temps are lower. But I have no real confirmation on what the frequency of the miner is.

Ill let it run alittle more, anyone know how to get a ssh cgminer window open to see it running?

[daniel232388]

can i just do a simple firmware update on s9? or i must use the sd card?

[Shad0wSmurf]

Tbh, the firmware is specifically designed for s9i, in so, that it won't do a firmware upgrade for another s9 unless you have the model name returned as S9i.

With that, it's a open source firmware, so, there is a file which you can edit to make it read as what ever model you want.

[vincl]

yes, I launched it from the sd card,
this is antminer with autotune frequency

and HOW did you boot from sd card? i copied the image on the sd card but miner wont boot from it. i have s9i ..
