Can we get some reviews here on the new firmware and cgminer?

I have 3.12.0 running stably and hashing 425-435 at 600 clock speed.

Any reason to upgrade?

So far, it seems like maybe if it ain't broke, don't fix it.


Original firmware, HW 1.1, Flaky Pi, Ubuntu 12.04 LTS, cgminer 4.0.0

Hashes for 10 - 20 minutes, disappears, hotplug finds it & starts hashing again.

Clock speed steadily drops from 612 to below 550 over a period of 14 hours. Stays at 600 the longest.

Hashrate varies from 360 GH/s to 400 GH/s (poolside) as  the clock speed changes.

Actually, my BabyJet is hashing about 400 GH/s when overclocked between 600 MHz and 612 MHz. It would probably be more, but it keeps disconnecting every 10 - 20 minutes. Fortunately, the hotplug feature in cgminer 4.0.0 finds it again within seconds.

I've Emailed HashFast a couple of times about the Pi. My latest Email was about simply sending me a firmware loader.

All of this has given me a chance to brush-up on my *nix skills. I haven't messed with this stuff in 20+ years... It's actually been kinda fun. Twenty years ago, there was no such thing as github...


Just a suggestion since you have the programming skills - why not try one of the programs to emulate the RPi on a desktop while you wait for Hashfast to never get back to you?

This one seems promising: http://xecdesign.com/qemu-emulating-raspberry-pi-the-easy-way/


Hmm... It does look interesting. What jumps out at me is the "Arch Linux requires a few tweaks to work. These will not be explored in this article."

Well, I've got nothing to lose by trying it, and might get my BabyJet running like it was for the first ten days...
