Hi guys, I recently bought a used Chili miner for cheap and it ran fine for a week. Today, my pc had a BSOD and rebooted. After that the chili miner is no longer discovered by Windows. The power led comes on and the last led, starting from the usb port, is flashing as soon as the power is up. No other LEDs comes on.

Any idea on what is happening?

EDIT: I resetted the MCU and now only the second to last led is flashing...
I tried updating the drivers, it says up to date.
Left the Chili miner unplugged from power and USB for a half hour and plugged it back, same results
Unplugged the miner, rebooted the PC, plugged it back, no luck.

Is it quite hot where you are? That LED will flash during startup while it's waiting to calibrate the on-die temperature sensors, but if the ambient is quite high it will continue waiting indefinitely for the board temp to get to a more normal temperature.

The room was quite hot so I waited for the night. Now if I plug the power in, without the usb cable, I see some leds flashing and only the last 2 will continue to flash for a little while until it all goes dark, power led still on.
If i connect a usb cable nothing happens, either on the pc or the chili.

i cant seem to get cgminer 4.3.4 to play nice with one of my chilis. it recognizes it but keeps giving bursts of hex2bin scan failed. and it presents 0 hashrate

Was this the one that got rained on? It doesn't take a whole lot of moisture to get corrosion when you have voltage present, so I would guess that might be the problem that was cleaned off. I had 16 of these in my garage, and it's like a Saharan dust storm if I hit them with the compressor. None of them seem to have any issue with being outside, as long as they stay dry.

Yep, and it was dead the last time before I cleaned it and got it running. Perhaps the rain plus corrosion allowed things to go bad again over time.

But it is working , and it could be just sensitive components.

And oddly enough my "dead" Chili is back to life and fully operational. No more 4 LEDs.

Why?

Well, before I was going to add it to my collection I did a complete cleaning of it first with spray on electronics cleaner and a nylon brush, followed by a nice alcohol bath (95% isopropyl). Plugged it in one last time and...

It worked perfectly. Over and over again.

I think the problem is the circuits for the power supply on the side there are susceptible to either resistive or capcitative leakage based on dust and normal stuff. Why people don't conformal coat these things is beyond me. However cleaning it off with Alcohol fixes the problem.

Yes, it's hashing again now. But I will shut it down to mount it. Eventually.

Like old fashioned tv sets, the dust burns on, then starts grounding the high current items.
A Polish tv repair man near me, used to make a good living cleaning problems like this.

I managed to get my Chili (Lucko batch) working that i'd been having issues with after flashing the bios to 1.0v - it will mine happily IF there is a fan plugged into the fan secondary fan header - as soon as its removed the miner will not mine or respond to anything - i still cannot reflash the miner back but atleast its mining!

I spoke to someone else and they think there could be an issue with an overcurrent and need an additional resistor required?

Any thoughts MrTeal or Lucko?

No, there's no need to have a fan plugged in. The tach input isn't monitored.

If you can mine with the board but it shuts off if you remove the second fan, it sounds like there is a hardware fault on the board. I am not sure what the other person might have been talking about with overcurrent or a resistor, but nothing like that should be needed.

If the board was from a Lucko batch then the 1.0v may never work, only the highest speed Chili's (38Gh) seem to handle the new ECO 1.0v properly.

Mr Teal and Lucko had some comments on this a few weeks ago.

EDIT:- check your cooler for contact with the chips

This board is from Lucko's batch.

Now it's with the 1.0fw and when i manage to start it runs very stable:
BFL 0: 66.0C | 32.18/32.13/31.32Gh/s | A:0 R:0+0(none) HW:1824/3.0%

Actually theese problems started after several days runing this fw and without the extra fan cooling the board and regulators.

I doubt that it will be the cooler contacting the board since it's runing now, only hard to start.

1V limited, to bring power use down to ~4J/GH
https://www.dropbox.com/s/b9f9ne7ilwl3ap8/Chili14e1v0.hex

This is the one i used to reflash - it had the slow rise on it before - this is after i flashed it with this firmware...

Ah, I was talking about when you tried to flash it back to the slow rise and it didn't work.

Erm no - i've not seen the link for this firmware - ive been away this weekend due to rebuilding all my PCs and mining rigs racking. I'm going to try again with the chili tomorrow.

Thanks for the info, I've tried it and it's better now, but after simple bfgminer restart I connot start it again:
[2014-06-09 02:39:54] BFL 0: Failed to open \\.\COM12
[2014-06-09 02:39:54] BFL 0 failure, exiting

I have to cool it down more to start mining, this is getting like catching the wind

First I have to cool it down, then I have to keep it warm to work without issues... nice1

Maybe a fw that prevents this waiting state will be nice, at 1.0V or less if possible I don't know the minimum for this BFL chip

Edit:
I can boot easier with the 1.1fw, 1.0 is almost impossible to boot ... maybe I can not flash it properly

I think it's time to give up on my chili, it was runing fine several days after I removed the extra fan, but I found the device with leds 1 and 4 i guess on and 7 blinking, after restart the same. After power down for 10-15 mins it started, but with a simple restart of the miner and the chili stopped responding again.

I tried to flash the 1.1fw and the 14e normal fw - only led 7 blinking and with the following result:

Code:

ENGINES: 128
FREQUENCY: 260 MHz
CRITICAL TEMPERATURE: 0
TOTAL THERMAL CYCLES: 0
XLINK MODE: MASTER

OK

Only with the 1.0fw I can start it mining after e long power down.

Try getting the chili temperature below 25C.
They respond better to programming at this point.
They also restart better from 25C to 29C. Above this temp, a restart is almost impossible.
If the onboard sensors read above 30C it will go into a waiting state until the temp drops.

Well, after a long and oddly enough profitable run I finally shut down my Chili. I had to turn it off to move it, and when I powered up it was giving me the four LED salute, which probably means the power supply is sunk.

Ah well, it did a very good job for me. Thanks Mr. Teal!

I am selling some Chili boards. They come mounted with accelero twin turbo 2, 3 of them are mounted with accelero mono plus

Have 18 boards available. Please post your best offers or send me a pm.

I also have bfl gear available. 2 minirigs (500gh/s +-10%) and 9 single sc (60gh/s +-10%).

Thanks

Sorry to rain on your post... but @ $.10 per kWh and a price of $8 per Chili, you could break even in 45 days or so... but after that 45 days... its a daily negative return.

I will offer you $5 for each Chili for the entire batch shipped at once. $90 + shipping. ~.14 BTC + I will provide a label to ship if you provide weight and dimensions of the box.

Anything more means 100% loss of money for any buyers.

This also goes for the BFL gear too since power consumption is about the same... you can't profit off these after 45 days or so from now at $.10 per kWh even at $.27 per GH/s. Similar to the Chilis, if you do wish to sell at this rate, I would offer $84 for one of the minirigs and I will provide the label. .13 BTC + shipping label.
