couldn't understand "change position jp4" how and where to change it.....lol....total doop

I am running this on multiple s9s off the SD card. None of them are S9i or S9j's.

Does this mean flashing to the controller is for the s9i? Because it runs fine from SD card on all of mine.

Hi Apprentice,

How did you managed to flash S9 with S9i firmware? I have managed to use microSD card with 2nd partition formated as ext4 so at least I am able to save configuration.

Cheers,

Hank

I will stay temporary with SD cards. Did you overclocked your miners? I am running 4 of them @650MHz and 2@675HMz. I need to know the safe frequency ;p
Also I have noticed that all miners running Braiins are very quiet. Will stay with Braiins.

Regards,

Hank

did you used the sd card or you used the s9 firmware update? can i just use the s9 ui firmware update to flash the braiins firmware?

@braiins could you please weigh-in/respond to the questions and concerns raised so far in this thread? You specifically requested to have all discussion of your OS occur in this thread and then disappeared.

Hello guys, sorry for the late response, we are working hard on the next release and definitely evaluating your feedback.

If you have some specific issue, it is always good to contact us directly via support ticket.


Antminer S9

Complete support for S9 (not only S9i) is our top priority right now, it should be out pretty soon.

As for overclocking, you can change the frequency, however, we do not feel confident to recommend any safe values. Be cautious. We are also working on voltage control so you can get a better grip of the overclocking.

We learned that many people do not know where pins/jumpers are and how to adjust them. We will update the guide accordingly. Please see this instructional pictures: https://imgur.com/a/dCUjXin

It is our goal to replace the closed bitstream and we are researching it, however, it is a difficult task and will surely take some time.

Installing Braiins OS via Antminer web interface is not possible, sorry.


DragonMint T1

Many T1s, unfortunately, does not have SD slot and we were not completely aware of it. While you can flash it directly into the built-in flash memory, we do not recommend it at the moment since it is alpha.


Support for other devices

Currently, we are focusing on Bitcoin only and want to polish support for Bitcoin mining devices before moving anywhere else. Thank you for the testing offers though!

did you flash it directly with s9 user interface or sd card?

Would you mind telling everyone what this edit is? The software seems to run great except for only being able to run it off the SD card, during the flash to controller it seemed to throw errors, as an example the 4th post in this thread.

It's an alpha firmware anything can get screwed up and become unrecoverable even if you follow the instructions to the letter. It's run at your own risk.

The file that you edited was in the firmware folder and was called Control and it was the top line for anyone else that wants to know.

To get it working there are two options
1) testing with an SD card, it doesn't matter what firmware you are running on the controller it will boot and run from the SD card.
2) Flashing directly to the control board, the miner must match what is in the control file mentioned above.

To flash you cannot be running the firmware from the SD card, the scripts do not copy any data from the SD card and only from your computer. You can either run it from the SD card where settings are not saved after reboot OR you can follow the instructions for flashing the control board with the braiins os.
