blackarrow should call them and say it was a gift Wink

and no more fees, and explain that was a motherboard...

yes, but here in Czech Republic (Europe) not all custom officers are brainless idiots and once you told them, if is a gift, then they will ask to for statement of bank account. if you will not show them this statement, they should contact bank directly and get the statement due to clearance process.

gift from hong kong? cmoon, maybe before 10 years.)))

there are just 2 ways:

*they will accept the description and value declaration and you will pay nothing

*they will catch it for ANY reason - you will definitely pay

wait there is a value declaration of 275-350$ ? and if they accept that price you dont need to pay VAT ? In my country you have to pay all VAT and taxes if you declarate as a XX price.

don't know what is declared value of the package, officers don't told me this, but it doesn't matter. once they will catch the package with really smart "lancelot" description, YOU HAVE TO prove real price of the package..at this point you should lie or tell them whole truth. otherwise, if they catch, that you are lying, you will come to serious troubles here. (this is, how it works in Czech rep. maybe in other countries it works different..)

blackarrow,

could you please explain me, why you describe the package as "lancelot" on not as "sample of motherboard" as before? because officers know what is motherboard but don't know what is lancelot, i have got clearance event and must pay VAT+CLO and other fees for extra storing package, etc.

next thing is, that will have to wait until tuesday because of this.

if describe as motherboard you don't pay VAT+CLO and other fees for extra storing package?

yes, because officers usually knows, that motherboard is something like green board with few chips related to computer hardware and don't care about rest. they just need to known something..

but lancelot? wtf is this? nobody except bitcoin community knows it, and THIS IS the reason, why they stop the package during clearance process. they need explanation and once this occurs, package will stuck somewhere on the airport for couple of days and you have to call them, explain them everything, sign some docs, declare the price and other shit around it. and of course, pay lot of various fees..

SO

blackarrow please, if it is possible, describe you package little bit better and SMARTER then "lancelot". with "sample of motherboard" or "computer parts" will be not an issue at all.

In all honesty this description is accurate and should help customs officers:

Motherboard PCB / Field Programmable Gate Array for testing purposes.

yes sure, 100% agreed, this is fine and I'm pretty sure that it will go through clearance process without any problems.

I received the remaining 5 Lancelots in my order today. They seem to run just a tad faster then the previous 5 I got... I'm not complaining

They are all working great. New ones: 399 MH/s, old ones, 379 MH/s.

You must have the 190 mhz firmware on the first ones. Buy a xilinx jtag cable and write the 200 mhz firmware and all will run at 400 mhashes.

Where can I download the firmware and instructions to flash it? (Preferably in Linux)

Weird, wish they wouldn't fight. I'm sure there's more too it. There was falling out. I respect cgminer because they were first. Bfgminer did better for me during the bfl singles. I don't know what to use for these lancelots.

Ruu \o/

Got mine today (thanks blackarrow!). Cute little thing; I stuffed it into my mining rig PC case.

Will now work with kano to get the cgminer code working (even) better with this device.

yep but in this case depends, if is package described as lancelot or sample of motherboard.

just check with other guys from our local czech forum and they are in same situation. all is about item description/declared value..

Your probably better off having it declared as something customs dont know. Then customs cant value it, and have to go by the declared value (whatever that is).

It's all a gamble anyway. Sometimes you get lucky with customs, and sometimes you don't. At least that's my experience in the UK.

Linux since 1997 RedHat 4

Regarding v42
So ... I had a look at the github and indeed it does dynamically adjust the MHz clock
So --icarus-timing will not fare well with that.
(as I mentioned it expects a constant MHz)

Since it can't even know what the MHz is it would be better to instead use a clock figure slower than it's slowest speed and a abort time of around 100 to ensure it's under the speed it always runs at.
So something like:
--icarus-timing 2.5=100
It will show the MH/s incorrectly, but it will still hash at the highest rate it can.

Anyone know if you can get more information out of the Lancelot other than just send it work and wait for the reply?
I guess once I've finished the code - (almost done but haven't had a lot of time today to do that last bit: sort out the chip initialisation) - I'll look at the github and see if there are other commands you can send to it ...
The random unknown MHz is actually problematic Sad

Okay, been mining for about 30 mins now, with power from the PSU and going strong, updated my earlier posts too as It was my fault that I didn't notice the not working green light on the power brick Tongue

Use --icarus-timing short for 400Mhash performance.

At least an hour.
The speed is of course an estimate, the A over a day or 2 will tell you if it is accurate.
However, 3 HW with 12 A is pretty bad too (20%)

Apart from bogus speeds reported by cgminer (900Megahashes), it actually started yielding better results... It had quite a lot of dropped packets but more accepted packages than the other devices.

Code:

Guess which one is running v42 firmware ?

However, if you look at the HW errors, it is indeed very high - almost 17%
I'd think that might mean it might shorten it's life?

Is there a way to clock that firmware down a little to get that HW number a lot lower?

Also the incorrect MH/s could be directly related to the firmware - the standard Icarus firmware divides the work in 2 on 2 FPGAs and runs at a constant MHz
I'm of course assuming that's what the standard Lancelot firmware does also and it seems to match that by reporting the MH/s correctly.
Do you know what that firmware does (and also do you have details about how to upload it? I have a jTag cable also that I have never used ...)

v42 firmware issues like HW (10% acceptable), miscalculated hashrates, jtag usage etc.:
https://github.com/ngzhang/Lancelot/tree/master/Bitsteam

@blackarrow
ICA3 is v42 ?
