Mining on an Android phone (galaxy nexus) CPU and BFL single

I managed to get cgminer running on Cyanogenmod 9.1.0

I think the phone uses about ~3 watts.

That is way too awesome  I need to change my phone asap

I've seen a lot of people spaming their videos for the BFL contest, but that's the only one I've legit been impressed by. Good Job!

I'd change the subject to a much more accurate "using Android phone as BFL host"
Has the benefit of not sounding like one of those "I can use phone as miner cause they use like no power I don't care how efficient they are" noobs

Hey, good job...

Did you post it on the butterfly labs forum, you could win a BFL single SC.

Requires :
-- Cyanogen source, compile custom kernel
-- libcurl
-- build files for cgminer
-- tweak cgminer pthread behavior (pthread_cancel)
-- compile ftdi kernel module
-- usb host mode working

Miss anything?

had to tweak some function names in cgminer
e.g.

Code:

#if defined(__BIONIC__)
        d64 = betoh64(*data64);
#else
        d64 = be64toh(*data64);
#endif

also removed the pthread check in the cgminer configure script

when I say i modified the pthread_cancel behavior, I basically turned the cancel call into a SIGTERM...i didn't rewrite the code to do the "right" thing (though, i initially tried and failed).

regarding the android build files for cgminer, i had to create the main Android.mk and ones for ccan and jansson.

the tricky part in all this was passing/setting the right build environment variables to "configure" for libcurl and cgminer (there are several blogs and forums describing this stuff, but it's still tricky. the Android.mk file in curl is a pretty good reference).

Is really nice what people can do...
What speed does it get?
and can you mine on the Gpu of it or is it only Cpu?

lol, nice work though!

trolololo is it strange I asked that or something? (Im still a noob in mining, so I may ask stupid questions... )

Lol, both questions were kind of stupid yeah

What speed does it get?
It gets to the maximum of BFL Single, +800 Mh/s, as the phone only acts as a controlling device, where the actual miner is functioning.

and can you mine on the Gpu of it or is it only Cpu?
None actually, is the BFL's FPGA that is mining away. You could say some mining is made on the Android phone CPU because the miner that handles all the operation is working on it, but no actual hash calculations are carried on the phone.

Hope it helps.

Oh ok, now its clear to me
So the device doesnt mine but controlls the mining devices?

To be fair, he does actually mine on the CPU on the phone. Then he uses the phone to control the BFL Single, which does the mining. Big difference.

[kaerf]

the phone itself gets around 500 KH/s via CPU mining...not something you'd want to run.
