What happened to the S1 upgrade Kits? Taken down because they're a better deal than the S4?

Bitmaintech.com is down. Here's hoping it will come back with the S4 available for purchase (at a decent price)

Sorry for not replying sooner. I doubt a RasPi will work. I haven't tried and honestly don't know how much the beaglebone is actually doing that's specific to it's hardware, and how much is just generic linux stuff.

If you've got a RPi and are willing to risk it, pop a new SD card with the image in and see what happens. It would be a cheaper replacement for sure.

As for BFG miner and it's antminer driver, I'd suspect that's more geared toward the antminer u1 and u2 USB asics. But if you try it and have any luck, it might save people some serious trouble.

Awesome. Glad to hear it's working for people.

The other image might be a waste of your time then. It will only automatically boot from the SD card on a reboot. A power cycle will require you to push the Boot switch button on the Beaglebone.

If you're powering down the S2, plug a wall wart or USB power supply into the Beaglebone to keep it alive while you do whatever requires the power down. Once you've applied power to the S2, remove the 5V power from the Beaglebone as it will pull power from the S2 IO board at this point.

The reboots from the SD card save the settings right?

I had that same problem when I loaded the image to the local storage. But it worked fine when I put the ubuntu image on the local storage and booted from the SD card.

Try putting this image on the SD card (image is from 1l1l11ll1l, credit where credit is due)

I don't think it's much different, but it may make things click for you. Once it's on try rebooting and see if anything sticks. You'll need to upgrade the firmware once it's on, but it worked fine for me.

You may be right about the difference between rev B and rev C. I really couldn't tell you.

Maybe rev B will let you install it tot he local storage and save settings. I'd try the image above from the SD card first though.

You're not completely powering it off are you? I just rebooted from the web interface and it seems to know to boot to the SD card unless I completely remove power.

Sorry, I just logged into my router to find the ip address. Keep in mind though once you boot into the Antminer image it will default to 192.168.1.99. I wasted a lot of time overlooking that.

I don't imagine the version should make much difference, they're basically the same except the Rev. C has more onboard storage.

Also want to point out another nice feature of this setup is that you can keep the beaglebone on despite removing power from the rest of the S2 by connecting a wall wart or USB 5V power supply.

I had some trouble with an S2 recently. Fixed it with an off the shelf Beaglebone Black.

I tried this with no luck. I ended up swapping the S2's stripped down beaglebone Black with a Beaglebone Black Rev. C(off the shelf)

I didn't have any luck with SD card solutions out there. Here's a post I wrote about swapping the stock S2 Beablebone Blakc with an Off the Shelf Beaglebone Black.

My Antminer S2 (kit) decided it didn't want to boot anymore after I shut it down briefly to re-route some cables. I scoured the forum and found all these "re-image the SD card" and "buy a class 10 SD card" solutions like this
https://bitcointalk.org/index.php?topic=515448.msg6315538#msg6315538

I tried all that and still got nothing. Fans spin, Red LEDs on backplane, 4 green and 1 red LED on IO board, No LED action and blank display on display panel, No LEDs on the Beaglebone Black control board. I emailed bitmain, they were useless.

I ordered a Beaglebone Black Rev. C from Adafruit.com ($55) to see if it would work as a replacement. The one that comes on the S2 is a stripped down version. Here's a few pics of the differences.

Here's what I did (first try, moderate success. See second attempt below for better results)
1-So I imaged an SD card with this Ubuntu image for the Beaglebone Black
http://s3.armhf.com/debian/raring/bone/ubuntu-raring-13.04-armhf-3.8.13-bone20.img.xz
(Extract .img file, Format SD card Fat32, Win32Imagewriter)

2-Boot up Beaglebone Black. Once booted, insert SD card, press and hold Boot Switch button, press Reset button. (Beaglebone Black boots to SD card)

3- I put this image from bitmain into my dropbox, SSH into the Beaglebone Black, and wget bitmain image dropbox link to download it.
https://docs.google.com/file/d/0B9mK2-whJv8cU0Q5R1hIQTJnRVU/edit

4-Once downloaded I installed it on the 4GM onboard eMMC storage with this command:
sudo dd bs=1M if=bitmain.img of=/dev/mmcblk1
(note I changed the name of the image from bitmain to bitmain.img to simplify things for myself)

5-Once finished power off Beaglebone Black. Attach to IO board from S2, insert IO board into backplane. Apply power.

RESULTS- This works, but if I rebooted the S2, changes were not saved. Had to re-enter pool info, network settings, etc. everytime. Couldn't overclock. Basically, what I think is happening, is that the firmware is set up to write settings to the SD card, but since I was booting from the onboard eMMC storage and didn't have an SD card in, it wasn't working. (Note, I didn't try just adding and SD card to this setup, but it's possible that may work fine) I'm sure it's also possible to tweak the firmware to write to the onboard storage, but I'm not the guy to figure that part out on my own.


Second attempt, more ideal results.
1-Same as above

2-Same as above.

3-put ubuntu image from step 1 above into dropbox and wget ubuntu dropbox link
(supposedly this version of ubuntu will check if there's a bootable SD card and prioritize that over the ubuntu image)

4-repeat step 4 but replace bitmain.img with ubuntu.img (note, again, simplified renamed image files)

5-Power off, reboot.

6- Flash bitmain image from above link to SD card (Class 10 SD, Format Fat32, win32imagewriter)

7- Insert SD card with Bitmain image into Beaglebone Black. Press and hold Boot Switch button, press Reset button. (supposedly rebooting should have booted to SD card image but I didn't find that to work as expected.

8- Power off Beaglebone Black, attach to IO board from S2. Press and hold Boot Switch Button (this is kind of a pain with the IO board on but doable), apply power to Beaglebone Black via USB or wall wart. Insert IO board into S2 backplane. Apply power to S2. Remove USB/wall wart power from Beaglebone Black.

At this point, it's booting from the SD card, and when restarted it actually boots to SD card without using the Boot Switch button. Settings are saving properly and I'm hashing again, overclocked to 219 MHz.

I'm still trying to get a replacement S2 Beaglebone, but at least I'm up and running in the meantime.

Hope this is helpful to someone.

Thanks,
I wasn't sure if it wasn't going to happen at all of if bulk pricing is still being negotiated. Sounds like the latter.

Waldohoover, I'm confused. Do you have an update on the group-buy, and pricing from Bitmain? I'm seeing the S3 listed for sale on their site. Can you clarify where things stand at the moment?
Thanks

I get "500 internal server error" but otherwise same result.

Did you format the card before writing the image to it? If so what file system did you use? If not, was it already formatted and if so what file system?

I'm having the same issue. No Network connectivity, blank display, no front LEDs, backplane LEDs all red. I tried what SD cards I had on hand with no luck. I've ordered a brand new Class 10 4GB.
Thanks.

I'm experiencing problem #1. Did you get yours working? If so how?
Thanks.

I'm interested but unsure with no pricing. Can you add me for 2, pending price info?
Thanks

Same here.

One of mine does that occasionally when I reboot it. I've found that going to System>Startup and restarting some of the processes seems to get it to click. I usually just restart "network" then "cgminer". Doesn't get to the heart of the problem, but it gets me up and running.
