try "sudo bitcoind"
can someone tell me how to delete the blockchain in ubuntu and start a re-download?
unless you can tell me how to get out of this error:

Code:

Do you want to rebuild the block database now?

Run bitcoind in non-daemon mode, and answer "yes" when asked if you want to rebuild the block database.
(The rebuild will take a long time.)

Now i done with toolchain, trying to build mips binary with my changes - seems that its overwriting my changes by downloading cgminer sources from git and repackaging it in cgminer-*.tar.bz2, then unpacking it and building. Damn.
EDIT:
At last! Cheated build script by repacking sources with my changed files to cgminer-3.3.1-.tar.bz2
Now going to test it.
ADD:
Test FAILED. 
Something strange happened, new cgminer started, but no accepted shares received and no temp/fan info. F*ck.
It's WORKING as intended!!! Now with options --avalon-invert-pwm --avalon-temp 0 fans going to full rpm, not stopping. Going test is a bit more with different temp targets now. Previous problem was probably caused by multiple cgminer instances running.
ADD:
Still something strange is going on, when i set target temp to 50 and real temp is going over it - fans is stopping!
Need to check calculation regarding xor(0xA0, fan).
YEP, wrong.
20 ^ A0 = 80
40 ^ A0 = E0 <- stops here
80 ^ A0 = 20
Need recalculate. XOR is not suitable, must be correct and more universal piece of code with mix/max/invert options.
ADD:
Added options to allow set fixed PWM value from arguments, and it looks like following from measures

--avalon-auto Adjust avalon overclock frequency dynamically for best hashrate
--avalon-invert-pwm Enable avalon use with inverted PWM fans.

Trying to set a build envirement via build-avalon-image.sh --clone to make cgminer binary and image with it. Really, it takes a long time to build a toolchain.
It sure does take a long time. I built an image using that script back when it used cgminer 2.11.
It ended up using 6 gigs of disk for all the things, and took many hours to complete on a 6 core system with fast fiber internets.
Once you do it once, though, subsequent builds should go a lot faster.

Got some errors in process due to $LD_LIBRARY_PATH variable .. now need to run again >_<. Changed git path in script to clone latest cgminer 3.3.1 also.
ckolivas, can you also upload to git changes that you made in luci / cgminer-webui , please?
currently it's taken from here
git clone git://github.com/BitSyncom/luci.git && (cd luci && git checkout -b cgminer-webui origin/cgminer-webui) )
I know what i must change to be able to run inverted pwm fan, but it's not so easy in first time to make binary for avalon with option enabled xor(0xA0,fan) in avalon_init_task() ... Im intending to buld a functional image identical to 20130627 for now from sources, then i will try to make changes.
EDIT:
So basically, i edited the sources and compiled it successfully!
Only problem that toolchain is in process of building right now, so i have only binary for x86 now.
What i edited :
in cgminer.c
in driver-avalon.h
in driver-avalon.c
That's all. Now only testing is needed.

just to be clear; that firmware your link pointed me to doesn't require any unpackaging or unzipping, right? just download it and then upload to avalon?
http://ck.kolivas.org/apps/cgminer/avalon/20130627/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin
file as is. Sometimes you may need to power it down for a minute before powering it on again after a major change if it doesn't start hashing immediately after flashing and restarting automatically.
and this totally replaces xiangfu's official avalon firmware?
Basically yes.nice. glad to see you're in charge. i had good luck with cgminer and my gpu's.
if i get these mofo's working, i'll be tipping. thanks.

Got one b1 overclocked with blue fan running fastest i ever seen....very few modifications needed

Basically yes. Buy the way do you get usb disconnects? How often do you need to restart your unit. My batch 2 is coming shortly and i will have some clue what is going on with USB there. I have removed ftdi driver, tried direct usb connection to various hosts including PC and USB just disconnects from time to times. If i wait long enough it reconnects and all is fine. I did it just once otherwise reboot not to waste time
Can you comment?
I do not get usb disconnects any more with my latest code and with wifi disabled.Can you comment?
what's your latest firmware link?

I don;t understand. What is ambinet?
ambient 
I don;t understand. What is ambinet?
350 and pretty cool without airco 
(1 fan on max rpm)
(1 fan on max rpm)
How do you set your ASIC to be like that? I'm getting 46 degrees. its crazy!
With Ambiniet about 15C. Temp1 is showing at lest +5 when mounted inside
PS: by the way i am prety sure that all reboots/hangs are due to USB disconect issues. I have tried whatever i can but mu unit needs rebot twice per day.
