Mining crypto coins with A20-OLinuXino-MICRO?

Crypto coin craze is still going strong with Bitcoin price reaching $880 (up from ~$15 twelve months ago).
Everyday there is a new crypto coin being released to the masses.
I just wanted to test whether the SoC in my A20-OLinuXino-MICRO is powerful enough to dig the virtual gold.
Unfortunately the Mali 400 GPU doesn’t have OpenCL support, so one can mine coins only with the CPU – dual core Cortex A7.
I installed pooler’s cpuminer from AUR and below you can see the results:
1. Bitcoin (and all other SHA256 based coins):

CPU @ 912 MHz, RAM @ 480 MHz, ondemand governor:

With the current difficulty of 1418481395 and hashrate of 643 kHash/s (overclocked) you’ll mine 1 bitcoin after 12000 years 🙂

Good luck with that

With 1 kH/s you’ll mine around 0.1 litecoins (worth $3.4) for 1 year with the current difficulty of 3195.34:

Just enter the price of electricity in your area and board consumption under load (should be not more than 3-4 W) to see your profit (or your loss 🙂 ).

    Thanks for your test, another thing I don’t need to proof by myself.
