Seems Scripta (scripta-20140408.img.gz mox235 version) image for Rasberry Pi is not hashing stable and swings from 17Mh to 20Mh/s for my 4 Gridseed Blades. If I just use cgminer (http://cryptomining-blog.com/1990-updated-cgminer-3-7-2-with-support-for-gridseed-5-chip-and-80-chip-gc3355-asics/) on windows it will get a stable 22Mh/s, but the only problem is my gridseed blades doesn't always show up even when you unplug and replug in after started and using hotplug=5 or 10.

Using https://github.com/mox235/scripta (scripta-20140408.img.gz)   posted a new version and will test tonight, but bfgminer doesn't produce the same hash power as cgminer on miner or pool side. I can only get 14-16Mh/s with bfgminer.

Hashra 1.4 Image  (just released)  locks you to 800freq or 850freq which isn't good because 838freq is the sweet spot for blades to produce low hw errors. Yes I know a blade version will be released, but I need a solution today.

Only way to get cgminer to detect devices is update driver one by one to the STelectronic driver one then use zadig select device one by one to update WinUSB driver after starting cgminer. Once you close you need to revert the driver back to STelectronic and use WinUSB all over again which is crazy! Any tricks to have cgminer find the devices every time with no issues?

https://github.com/jmordica/cgminer-gc3355 seems to have it stable and doesn't have any issues?? (https://bitcointalk.org/index.php?topic=571255.0) but I don't know how to compile it for windows or update a raspberry image with his version, if it is stable??
 
Any feedback would greatly be appreciated!

Thanks,
Rob

minerd.exe --gc3355=\\.\COMxx,\\.\COMyy,\\.\COMzz --gc3355-autotune --gc3355-chips=40 --freq=825 --url=stratum+tcp://pool:port --userpass=user:pass

the last update is not avaible 

They look like renders to me.

CPUMiner fork? please elaborate.

I encourage everyone that wants this CPUminer fork for windows ( like me ) to write to http://cryptomining-blog.com

they have been compiling ones before and worked great. Hopefully if enough ask them they will do it with this one

password fields missing for backup pools, intention or forgot?

Can you provide a binary for the rasp ..... for it? Does it work with g-blades?

apt-get update
apt-get install -y build-essential libtool libcurl4-openssl-dev libncurses5-dev libudev-dev autoconf automake screen
git clone https://github.com/siklon/usb-miner.git
cd usb-miner/software/cpuminer
./autogen.sh
./configure CFLAGS="-O3"
make

Now if CPU miner was fixed to show KH/s it will be perfect

That is great!  Wish I new enough to help with debugging.

sandor - just to confirm, is this for single mode operation only or both single and dual?

I have dropped cgminer, tried all possible forks on 2 raspi's with 10 and 20 gridseeds connected.
Lots of HW error's and they all seem to crash after a while.

On my setup, bfgminer runs most stable (https://github.com/luke-jr/bfgminer/tree/gridseed)
It also has a higher hashrate reported on the pool compared to cgminer, especially on p2pools.
Don't know if it supports blades yet.

The new cpuminer fork from sandor111 also looks very promising. It runs stable on raspi and has this auto tune function.
Some pools don't work yet, but there should be a fix for this very soon.

Seems as thought something was tweaked in the auto-overclocking,  more aggressive than before?  I am getting more hwe with V3e than before.
