help worked

type help or -help or ? or anything!

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.

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 Have the same with out the jumpers.

But I'm using GND, Rx Tx. And I get either no output on start up, or I swap Rx, Tx around and get (by startup I mean I've selcted serial,  I have com and baud set in putty, I start putty under serial connection, I then turn on S3 to a stream of gibberish like below/ nor nothing)):

Which doesn't look right either. At no point can I type.

Any help? I'll chip in to bounty too

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 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.

is this what I need to do?

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

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

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

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  

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.

-edited for clarity-
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 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?

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

Impressive.

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

Will look into all peoples recs.

Images removed or security reasons

thanks

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.
