Any difference you see in HW% with the latest firmware is almost certainly sheer coincidence.

Hello, someone can build the latest openwrt trunk with the lastest cgminer? (4.1.0)

Here you go, and given the bugfixes that went into 4.1.0, this might be one of the best firmwares ever, though it's completely untested.

Ty.. This one seems a bit more HW % :S. And today morning i should power off, power on the PSUs to get them hasin`...

Check your cables. I am using the the newer firmware on my AVY1's and the HW% is lower than before.

Check what? I dont touched my unit, just flashed the FW .

It's your unit not the firmware.

It would be a happy coincidence though as mine dropped a bunch as well.
It runs very fast and stable as well.  I have been peaking on BTCGuild with it at 86 gh/s at 350 with sustained at 83 gh/s.
The new firmware rocks.

Do you have Teamviewer I can help you fix this

[ManeBjorn]

He did a great job on mine through teamviewer I can vouch for him with that.
I hope it helps and Happy Mining.

No but i can download it, thank you

Send me a PM info with the ID that it gives you and the password it gives you so i can connect and have a notepad open so we can chat

I'm more than happy to take the credit if things get better 

[ManeBjorn]

The whole unit works better across the board.  This was an excellent update.
Great job.

It's an avalon Chinese copy, 55nm

As for the hardware issue Tom_o pointed me in the right direction already...

"1) Fuses blown on those modules (upper left of each submodule on the blade PCB, usually marked "FUSE1" or two fuses right next to each other with a "P" on them - see the btmine thread in Group Buy).
2)  Bad connection on the pits from the blade board atop the blade connecting to the 4 PCBs of 2 worker modules each (the pins could be bent or misaligned).
3)  Power supply marginal, such that only certain modules are getting enough current.

You can check 1) with a voltmeter (some resistance across fuse means it is blown, near-zero resistance means the fuse is fine)
You can check 2) via visual inspection
You can check 3) but putting in a known-to-be-beefier power supply and seeing how it goes

Personally, I'd go with #1, but that's only because that's what I experienced with my own Avalon clone.

Hope this helps!   And good luck!"

I've checked the thread and btmine had posted a picture of the fuse location so thats where I'm going to start...

Ineterested to know if anyone else has managed to fix the possible fuse issue? especially where to get the fuses from.

I'm useless with a soldering iron, tempted just to live with it.

HELP - It's not a fuse issue, fairly sure that this chip is the problem. Anyone else had the same problem? Can I get a replacement?

What are acceptable temps and HW errors on Avalon2 200Gh/s?

I'm seeing about 252k errors over the past 14hrs with a temp a 49 and freq of 1400.  This is a dual card rig.

Coming from GPUs, that seems like an awful lot of errors, but dropping to a freq of 1300 didn't seem to do much.

Good for 55nm clone?

If anyone is interested I am selling my Avalon Gen 1.
I just updated the firmware using this thread and it is running solid at 82 gh/s to 83 gh/s.
I really don't want to sell it but my wife and I need the money. I have a 3rd spinal surgery in less than a year and a half coming up in a few weeks.
I appreciate you all taking a look and thank you.

A new openwrt with 4.2.0 ? TY.

[pepo]

Hello , maybe a stupid question but i cant enter to the miner , i use ipscan and it is not showing it , i dont know the miners ip ive tried 192.168.0.100 that is the factory custom but it is not there, anyone knows how to mannually change the ip , thank you.

try connecting a computer/laptop directly to the avalon with network cable, set it (your computer/laptop) to a static ip 192.168.0.101 , now you should be able to log in to your avalon (192.168.0.100) , if not.. maybe try resetting the avalon router to factory defaults first

there is a reset switch on the back of the router iirc

Failsafe mode

When the configuration no longer allows you to log in via any network connection (e.g. lost password), the OpenWrt failsafe mode can be entered via the single "Reset" button on the device. However, in contrast to the generic failsafe instructions, for the TL-WR703N you have to wait for ca. 10 (10-12) seconds before pushing the "Reset" button after powering on the device. If the button is pushed immediately after powering on, the single blue LED will start blinking, supposedly indicating some failsafe firmware recovery mody of the embedded bootloader (not yet discovered how to use it). In this mode, the OpenWrt failsafe is not being started. Instead, wait for slightly longer than 10 seconds and - as soon as the LED starts blinking for the first time after powering on the device, push the "Reset" button for ca. 1-2 seconds. Immediately afterwards, the LED will blink rapidly (multiple Hz) and OpenWrt will be in failsafe mode.

- The above didn't work on a Ver 1.6 box running OpenWRT r33312. To get into failsafe mode, power up the device and wait until the LED starts flashing (about 2Hz). Once it starts flashing (within about 4 seconds) then quickly press the button. The LED will then flash much faster and the device will be in failsafe mode.
