Ok...looks like I am in? I can telnet into the box It says at top to use passwd to set password. I followed this site http://wiki.openwrt.org/doc/howto/generic.failsafe. But it just stays in failsafe mode.
I bounce the box but it just stays at 192.168.1.1 and I can telnet and SSH to it. So I downloaded the latest avalon firmware, but I am not a linux guy...is it possible to flash the firmware using the .bin file from a telnet or ssh session? I don't have a lot of coin but am willing to send a C note to whoever can work me through getting this this back online and hashing. Please Pm me so we do not clutter this thread.

Thanks

Very cool.
Now if they can deliver in a timely manner it will be great.

Very similar spec to an Antminer with OC when in eco mode, both 55nm chip

things are going to get competitive around here

Wow did you guys see this??

Avalon is making new 2U 300GH/s systems?

http://avalon-asics.com/product/avalon2-new-2u-size-machine-300ghs-with-a3255/

What is your LAN IP subnet?

example:

My LAN is on the 192.168.75.x/255.255.255.0 subnet.

So one of my miners has a static IP of; IP - 192.168.75.10, subnet - 255.255.255.0, gateway - 192.168.75.1, DNS - 8.8.8.8

Whatever the LAN IP is on the box, a router, is connected to your internet connection or modem is the gateway. If you don't have the correct gateway the Avalon's fail to connect.

You connect the new psu the same way the old psu was connected.

Help me.
I downloaded all the firmwares from may to december.
I have bought 2 wifi routers and used cat5 connection. (i use 192.168.1.100 as static IP)
But this message is constant.

[Firmware Version] => 20131229
cgminer: 698d677
cgminer-openwrt-packages: 54d7569

Can I trust this ftp?

What firewall settings (in OpenWRT) do you use?
What pool should I use?

search this thread for "failsafe".

I went and did something stupid I guess because my box will not respond. I re-flashed the box and forgot to unchecked the settings box. I could not reach the box and it would not ping. I did a reset of the board, changed my nic and plugged  the miner into my notebook. Still no ping. Powered down and back up still no ping. It just sits there in idle mode...yellow and green leds lit and a slow 1 sec. pulse coming from the on-board nic.

Is there a way to force flash these things without using the web interface? Googled a for a while but did not find the answer.

Thanks ahead of time for any info or
a finger point in the right direction...

See if lightfoot can fix it.
He is great with all sorts of board upgrades and repairs.

Yep, the area looked like it was completely charred and the solder pads a completely gone, not worth trying to rebuild.  I removed the pinheader from the fried submodule.  And it's up and working good as new -1.  I also ordered 20g of MX-4 and will be applying that to the modules later this week.  Thanks a ton

the fried capacitor is 4.7uF/16V|SMD ceramic capacitors|C8, C17, C146|CAPC2012L|3|4.7uF/16V/X7R| from the BOM.
this should work for a replacement: http://www.mouser.com/ProductDetail/TDK/CGA4J3X7R1C475K125AB/?qs=sGAEpiMZZMs0AnBnWHyRQEWjzA2rN6H9lzWbV9EGTp4%3d

the larger cap next to it would be 22uF/16V|SMD ceramic capacitors|C6, C7|CAPC3225L|2|22uF/16V/X7R|
http://www.mouser.com/ProductDetail/TDK/C3225X7R1C226K250AC/?qs=sGAEpiMZZMs0AnBnWHyRQEWjzA2rN6H938yxxtUSLGM%3d
I would replace it also.

you will have to check for board damage after removing the caps to determine if it can be repaired. if not you can remove the connector to disable the bad section.

changing the miner count won't help as this miner section is not on the end of the board.

I would also recommend replacing the thermal interface material with a quality compound such as arctic cooling as5 or mx4.
you can search back in this thread for tips on doing this.

Whelp today I noticed no sound was coming from the office.  Turns out my Batch 2 Avalon is giving me a red and yellow light, and was also giving off an electrical burn type smell.  I tried installing a new PSU same problem. so then I began unplugging individual modules.  Low and behold one of them is the issue.  I will be taking pictures of it soon to see if anyone can help.  I guess my next question is, Can I NOW run my asic overclocked with the stock PSU with only 2 modules online?  Thanks, and please let me know if there's anything else I can do to help figure out the issue.

Is there anything I can do to fix this, I can solder I just would need to know what to solder.

I've checked out the BOM list, and to be honest I have no Idea what I am looking at http://downloads.canaan-creative.com/hardware/A3256/avalon/2013-11-30/HASH_UNIT/BOM/hash_unit.md
It looks like the smaller SMD component and the 2 slightly larger ones need to be replaced and possibly the Capacitor.  


In the mean time can I desolder the pin header that gives it power?  Would I need to desolder it's adjoining one as well?  Also If I were to do this, Would I need to set my cgminer config miner count to 23/22.

Edit: It appears the pads to solder the components on are completely charred.  My question still stands regarding desoldering the pinheaders.

Figured out I needed to relaunch my browser. so firmware updated, it's mining but still the same speed issue!
all my other miners (not the same type - block erupters..) are reporting the right hashing speed in both their local interface and the pool's reports

Well I tried flashing to the december firmware. I am kind of stuck, it's been flashing for minutes, the page says not to turn off, I can still ping the IP that I was using but the web interface does not load (yet?).

how long is the process supposed to take?

Update: It's fluctuating between 160 and 190 GH/s by looking at the numbers reported by BTCguild. really no clue what's going on here

Power Supply Question:

How do you connect a new psu to an Avalon Gen 2 box with 2 modules?  Anyone have any ideas?

I posted in another thread but it looks like I should have posted here first.

I've got a 200GH/s Avalon clone unit. I struggled finding the IP it was shipped to me with but thanks to angry grip scanner I was able to figure it out. I set everything up and it's hashing.

when looking at the Cgminer status page off the web interface, it was hashing 200GH/s per spec, no problem. However both mining pools I usually use return a lower hashing number by roughly 20-25%.

I tried overclocking ~ 15% (up to 1500) which gives me a hashing speed of 230 GH/s per, again, the web interface. But the figures in both mining pool dashboards return numbers again 20-25% lower.

I've mined with block erupters (blade and cubes) before and local numbers and more importantly pool numbers were correct.


I noticed I am running the 2013/11/10 firmware and that some people have upgraded to the end december firmware but I am not sure if that would have any impact on performance like this.

Do owners of the same unit are seeing local hashing speed really different from the pool's numbers like I do?

Any help greatly appreciated

Thanks

Gerronimo,

Removal of the power cord with a 5 minute wait assures you that nothing survives that is in volatile memory :-)

Brethren and Ladies,

Over time I’ve read about the moaning and gnashing of teeth regarding the wireless capabilities of the Avalon devices.  While setting up a couple of antminers for wireless capabilities I stumbled to the idea that Avalons could be setup the EXACT same way for wireless capabilities.  First things first on your wireless route you need to write down the DHCP range that the wireless router assigns to DHCP clients.  You’ll need this in a bit.  The next thing you need to do is head over to BestBuy (or whatever store you choose) and pick up a Netgear Model#: WNCE2001-100NAS.  This little device is a wireless network bridge extender and acts like a really long Ethernet cable connected to your wireless network transmitter.  To configure your wireless bridge extender power it up and connect it to your computer (laptop in my case) via an Ethernet cable.  Your computer must be setup to request its IP via DHCP / automatically and NOT be statically set  Once you see the LAN light come on and the WAN light stabilize on eh wireless bridge extender you open a web browser and viola …. you end up on the wireless bridge extender configuration page.  This is where you link, via WPA2, your wireless bridge extender with your wireless network.  Once you have this done you restart your computer and power cycle the bridge extender and, since you have your Ethernet set to request IP via DHCP you get an IP that is *IN* the DHCP range that your wireless network provides to DHCP clients.

Remember where I said to note the DHCP pool range that your wireless network uses??  This is where that becomes important.  To use your Wireless bridge extender with your Avalon you’ll have to assign your Avalon a static IP that is in the subnet for the network of your wireless network *BUT NOT* in the DHCP pool range.  This is because if you assign your Avalon an IP INSIDE your wireless network’s DHCP range your wireless router will have no knowledge of this event and might inadvertently assign out the IP you assigned as a static.  When this happens, and it will eventually, things will be truly F^CKED UP.  So, now you have your Avalon with an assigned IP that is in the network range of your wireless router but NOT in the router’s DHCP pool range ….. so …. Plug in the wireless bridge extender’s Ethernet port to the Avalon’s Ethernet port using an Ethernet cable and ….. viola …. The Avalon *THINKS* its talking to your mining pool via a wire but in reality is talking to your mining pool choice via a wireless network.  Hope this helps …. And if it does feel free to throw a brothah’ a tip at the tip address below.
