bitmain s3 serial connect?

[macgyver007]

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.

Sent from my iPhone"

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

my entire s3 is bricked :/

well just the board i guess but the entire unit is down.

im going to crack it open tonight and get digging but i dont have much time and have to fly out tomorrow so idk wtf i might have to take the biotch with me

Contact Bitmain.  If it is within 90 days I believe it is considered warranty.  (I could be wrong on timeline).

I do know I was a batch one I got bricked and was out of warranty.  They are willing to sell and ship the controller very fast to you (was same shipping as miners use).  It is a setback on ROI but at least not a brick.  And in my case I got a 1.1 ver of board and had a v1 so guess it was a upgrade.

well If i could only get this last one working....

Will look into all peoples recs.

Images removed or security reasons

thanks

Very impressive setup! How many S3 total?  What did you do to get so much electricity there?

Impressive.

[ChineseSavior]

i have 13 but the 1 is dead/my learning project. so 12 there plus the c1.  

i ran the dryer socket to a electric vehicle conversion plug to pdu to psu

**edit**

here is the board



now what? where can u buy the tx thing?

Everything you need is right here in this post...no guesswork involved just RTFM  

I circled the 3 pins where you connect to in red here:

Looking at the controller board straight on, the ground *should* be the pinhole on the far right, if not its far left (double check with voltmeter as I have no unit to test right now) the other 2 pinholes are tx/rx.
Once you confirm  the ground (0v on voltmeter), then connect tx and rx....if you get a load of junk on your screen reverse the rx/tx and you will see magic...well not really but you will see the data on the screen...for putty set 115200, no flow control, and make sure you have the correct COM port defined (115200,8,n,1)

I posted a direct link where to get the cp2102 earlier (the tx thing)

http://www.dx.com/p/usb-to-uart-5-pin-cp2102-module-serial-converter-81872#.VI6YldJ0yUl
There is no bs ad commission or anything for that part; you can order it anywhere on the net..I provided the link where I got mine to make things easy (or so I thought)

In Short...you need the thing in the picture (link provided) putty for serial connection and 3 bogo pins (that's what the gold pins are called)
Alternately you can just use sewing pins and push the sharp end into the connector MacGyver style, just don't move anything once you have them connected  

Once you have access to the miner, type

mtd -r erase rootfs_data and hit enter
then type REBOOT and hit enter...then wait 3 minutes before accessing the default miner IP address...do not power cycle the unit

Last of all...don't hold me responsible if anything goes wrong...but if I helped, a thanks would be great

I circled the 3 pins where you connect to in red here:

Looking at the controller board straight on in the present orientation, the ground should be the pin on the top (double check with voltmeter) and the other 2 are tx/rx.
Once you confirm  the ground pin, connect tx and rx....if you get a load of junk on your screen reverse the rx/tx and you will see magic...well not really but you will see the data on the screen...for putty set 115200, no flow control, and make sure you have the correct COM port defined...
I posted a direct link where to get the cp2102 earlier (the tx thing)  ...it should be the same or better version than the one I got years ago

@ChineseSavior

Did it work for you? I am in the same boat. Which hole is the grd?

Sure fire fix assuming hardware is ok and uboot intact is uboot based recovery, interrupt the boot process and set your computers IP to a static IP of 192.168.1.100. Start a TFTP server on your computer serving antMiner_S320141013.bin and run the following commands on your miner.

Code:

tftpboot 0x80000000 antMiner_S320141013.bin
erase 0x9f020000 +0x7c0000
cp.b 0x80000000 0x9f020000 0x7c0000
bootm 0x9f020000

there no need to re-flash the firmware as it is the NVRAM that is corrupt...your suggestion of loading the 20141013.bin will result in being unable to access the config pages as documented in the subsequent release....if anything I would suggest loading the 0826 firmware and then wget the ckolivas cgminer 4.61 but then we are complicating things more than needed...most here seem to have enough problem with putty lets not throw in a tftp server and hex addresses....its a bit of a predicament...0826 firmware with crap cgminer or Russian roulette with the next 3 builds....and all the while BITMAIN leaves the files for MORE people to &$#^&$ their miners up with...well done 
on a different note its nice to see the community working together

SSH in and execute the following to fix webui on the oct 13th firmware.

Code:

sed -i 's/Save\&Apply/Save\&Apply/g' /usr/lib/lua/luci/model/cbi/cgminer/cgminer.lua

To fix config pages after flashing a later release execute this command over SSH.

Code:

cp /overlay/etc/config/cgminer /tmp/cgminer.tmp && cp /overlay/etc/config/network /tmp/network.tmp && rm -r /overlay/* && mkdir /overlay/etc && mkdir /overlay/etc/config && cp /tmp/cgminer.tmp /overlay/etc/config/cgminer && cp /tmp/network.tmp /overlay/etc/config/network && reboot

TFTP recovery is usually required if the OS doesn't boot and you see it stuck bootlooping at uboot.

is this what I need to do?

[el_rlee]

I tried like this, but didn't succeed



The CP2102 offers me:

3.3V
5V
RST
GND

and two others, which are jumpered by default.

Ground should be the blue one acc. to my measurement. For the rest I would appreciate any help.

Thanks.

I offer a bounty of $30 in Bitcoin for anybody to deliver a detailed description that's working for me on how to de-brick the S3 controller board using a CP2102.

I Have the same with out the jumpers.

First, you DO NOT need to connect ground (and it looks like you are connecting the 3.3v line rather than ground in your pic).
Second, what program are you using to connect? You may need to set the speed, e.g 115200, aprity and data bits and / or set the display to ANSI.

I'm using Putty and I have from left to right connected Tx, Rx, Gnd, 3.3 is outer left pin, and 5v is outer right pin.
I will try without GND.
As far as my settings go in putty. I select Serial, I choose the right COM port, in this case COM3, I set baud to 115200, I hit connect, and that is my output on the screen.
I've done nothing with:"aprity and data bits and / or set the display to ANSI" and wouldn't know where to find it. When I try putty settings they don't seem to stick.

Thanks

I can not seem to find where you set the terminal display in putty, but I have previously used Realterm and when I got garbled output like you have, all I had to do was set the correct baud speed and set the terminal display to ANSI. I suppose in your instance you'll have to try out different baud speeds, but suffice to say you are on the right track.

I had pins wrong!!!!!!!!!! I'll get photo up in a second, don't believe the square point is GND.

I now have something better, but still can type.
