Topic: bitmain s3 serial connect? - page 4. (Read 9732 times)
i tried asking bitmain for more intel and this is what they said.
me: "Can you please provide link to product that can do as you describe? Thanks.

bitmain: "Sorry, I don't have it.
if you cannot restart it in your side, you'll have to return the board for RMA"
maybe ill try again?

Ancient Chinese secret?
sorry I couldn't resist....bitmain if you need some proper tech support I can help
... btw I am not a product...if anything I am a product of my environment
I can be your guide through this..its pretty easy really...helps when the thread doesn't move as well
I recovered a few S1 this way...just a little bit of a different procedure to clear the NVRAM
The only thing is I don't have physical access to S3 controller board right now, and need to probe the pins for tx/rx/ground ...kinda hard without the board in front of me, but if you have a voltmeter you can probe the pins and once you figure out the ground its even easier (ground will be 0 and tx/rx will fluctuate)..if it doesn't communicate with the tx/rx one way just reverse the tx/rx cables...off the top of my head the ground pin was on the far right side, but I suggest you probe them as I don't want to give incorrect advice...
If you have ever debricked a router its almost the same thing
To communicate you will use putty...more instruction to follow ASAP...sorry for leaving you hanging like this but my miners are in another location right now...if you have any questions feel free to ask

I wish there was a guide on it. I have my one that lost power during flash sitting on shelf. Would love to turn it into a backup.
I was out of warranty time so I paid for the part and quick shipping. I will say I thought it was fair considering how fast they shipped. Set ROI on that unit back a while but it's running great.
i dont understand? you dont know how to fix it, but you fixed it? im lost...
I don't know how to fix my old board via serial. I bought a new board from Bitmain. Replaced the controller board with new one I bought from Bitmain.
So I got miner up and running but now I have a board that is bricked I wish I could figure out how to fix and I would have a extra.

I think we need to ask Bitmain more questions. For example layout what order the 3 pins go in debug spot.
Also what program to use sending the commands.
Also what program to use sending the commands.
so that will work?
the CP2102 are cheaper. but 19$ is okay also
Does somebody have a picture, where to connect on the controller board?
This is the exact one I have and same place I ordered it from... you will need bogo pins (the gold pins) as well..u can find those in any electronics shop

What program are you using to send commands to board?
Also is it the debug it connects to on board? If so what is the order of pins?
Thanks for sharing info you did already.

what you need is a CP2102 USB to serial like this:
for this application you just need tx/rx and ground connected...don't connect the power output from the CP2102 to the controller board
this is not hard to do just make sure you connect the right wires to the 3 holes on the controller board
p.s. you cannot get these at future shop

if i can find a serial connect in the box how do I even do what bitmain is instructing after that?
how do I get in to install that code they show in there email?
Thanks for the help.

You can ask them to go into more info. Instead of buying a serial cable I bought a S3 controller from them.
I figure I will sell old controller to someone who has the equipment to re-flash/debug serial like they suggested to me aswell.
I paid for it and worked for me. I cannot blame anyone else for mine losing power during flash.
Alas I do not know.
