I actually spoke to ckolivas about adding this option to the finished cgminer with full usb code.

Yeah,

too little, but having an address where to send some tips would help as well, I mean, if each Avalon user sends 1 BTC per owned Avalon 100 BTCs are easily collected!

Thanks Aseras ... I know.. too late

I strongly believe that people want to show their appreciation for development but they just don't know who does what in this project.

If there was an option in Avalon's miner settings to donate X% hashes to the dev-team, I think a lot of the Avalon users would have used this.

no one loves me...

I leant my avalons to ckolivas for several days/weeks to do the firmware, paying him in hashes while he works. Luke never took up the offer, and the one try he bricked one of the avalons.
ckolivas has never messed them up besides tripping a breaker once

I also offered them to forrest to work on p2pool and he never took it up either. p2pool has serious problems with every asic right now.

We have greatly improved the stability and hashrate. I have week+ uptimes now and rarely a hard lock anymore unless we hit the hardware reset buffer bug.

We fixed a great many nasty bug including the difficulty bug, which prevented large shares such a solo mining from working. The watchdog would reset the avalon on high difficulty because it thought the unit was crashed. we found a lot of typos and debugged even building the firmware to make it a fairly simple process. We even taught ckolivas to get a VPN working under linux

I'd guess I've lost 50-100btc letting my avalons be used for development between downtime and "paying" whomever was developing.

The next step is to chuck the usb-serial code and go direct usb and remove a lot of the hacks and work arounds that were used and improve it a lot more.

ckolivas is greatly underpaid for the work he does. xiangfu is as well. He needs a new laptop.

If avalon or anyone wants to thank or tip me, Id' rather they pester team avalon to get ckolivas an avalon in his hands. it will be worth it for everyone. It would also be nice if I were "special enough" to get my batch 2 avalons a wee bit quicker

My 703n still running very old cgminer, if your build is ready for Icarus Im interested! Thanks.

Is this based off of commit 69bdc6f9883fbbf79e3e23d13cc6f2042154d072?  needs to be running that or it's going to cause everyone problems.

Sure, but I checked the donation part at the Avalon wiki and in my opinion Xiangfu did not really get enough "appreciation" for his work.

Good call.  Tip sent.

I've been using his build-avalon-image.sh script to build my own firmware images for WR703Ns with support for the various FPGA miners enabled.

I've been using them to mine on Bitforce FPGA Singles, CM1s, and Ztex 1.15y boards.  Unfortunately the Ztex bitstreams can't fit into the 4MB flash memory, so I've been loading them into RAM in /tmp after each reboot.  I plan to try a usb-storage solution for that later.

I can post my builds if anyone's interested.

No tips for Aseras? Xiangfu clearly thanked him for the work.

Can different pools mine different coins, e.g., bitcoin and bytecoin?

Guys don't forget to tip Xiangfu for his great work
 
 

How to add "4th,5th pool" under "More Options" ?


Edit: Found it... add: "-o ip:port -O user:pass" for each pool

It even works with more than 5 pools...

Hi

Thanks Aseras for the info/frimware. time to  release a new firmware with cgminer 3.1.1. a testing firmware uploaded here:

Happy Mining

Just browsed over this funny fan review, I can barely hear what she is talking, and that "smoke test" really does not make any sense due to different lighting each time

Ooooo there is a bug with diff changes? That might be why Avalon likes to freeze on some fast diff changing altcoins. Can you point to the commit where this is fixed?

If anyone has problems, I have a new firmware you can try. PM me for a link.

Based off cgminer 3.1 Fixes many issues especially certain problems with difficulty changes and some of the freezing.

I don't know what "mains net pollution" is 

The power going into my unit is VERY clean and isolated from all other loads. (think data center)

I'm tempted to go back to a previous firmware because the extra 2GH/s benefit is lost when the unit stops hashing.

 

Yes, it seems there are a few race conditions that can present themselves putting the PDU into an inconsistent state.

The end result is that all the values it gives out are 0 (see the screenshot I posted a week ago)

The only solution is to do a hard reset

The cause is probably related to mains net pollution. This could be a high power device like an airco switching on and off on the same circuit on your fuse box. Perhaps the spike only presents itself once a while and that is why you did not notice until now. It does not look to be software related.

Perhaps batch #2 and batch #3 will ship with a different design (some difference appear from the released diagrams)

Try to clean up your mains net as much as possible to play safe

I am using firmware 20130419. Unfortunately, I don't recall the previous firmware version I was using.

Prior to the upgrade on May 5, the Avalon unit ran without any problems.

However, after the upgrade, the miner has stopped hashing twice, and the only way to recover is with a cold reset. Is this a know issue?

Cheers!
