Topic: [GUIDE] GridSeed Blade (80 Chip) Miner Support/Tuning - page 4. (Read 38952 times)

I used a fresh debian install ... and the orginal cgminer from andreed ... wrong hashrate ... but doesn't matter ... and changed the cmdline ... slub_flag or something like this ... and it works stable 48h and more

not for me =( ... id give anything to have cgminer working on my rpi but the USB bus resets after a few minutes of mining and miners stop =(
I can only get minerd(cpuminer) to work stable on the USB ports since it seems to communicate differently through them or something... but cpuminer is like 1MH slower and for some reason it doesnt seem to report the pool accepting all the shares generated. Like 2 nonce found messages would scroll past but only 1 accepted at pool ... with no reject meessage either. Happens a few times a minute. So, the avg reported pool hashrate by minerd is like 1-2MH less than cgminer 3.7.2 hosted on a laptop.
I wish I could try bfgminer see if it works more stable on the rpi

The hub I have it all plugged into is powered as well.
So, I dont know wtf the deal is =(

without tweak in GC3355.c file BFGminer isn't ready to fully works with gridseed G-Blade,.
Bfgminer support the first gridseed(300Kh/s) but not completely the G-blade (5.5Mh/s).

The reason is first gridseed use 5 chips GC3355 on board, against 40 chips by board with the G-Blade.

I work on a patch but i'm not a guru programmer so actually my patch don't work very well.

I push it to github when it's done.

Hi

I played with my blades for few hours, read ton of online materials but did not find solution for my problem.

I connected blades to my home Windows server and the problem is when I start cgminer it does not detect blades. I have to unplug the blades, start cpuminer and then plug usb cables from blades quite fast so cgminer detect the hardware. It is frustrating as server is in the part of the house I have a long walk to and going there to do such stuff manually instead of remote desktop :/

cgminer works flawless on a raspberry ... super stable at 5.5 on the pool

I have two blades and with bfgminer they work only on 2.5 to 2.6 MHz
and also one of them after 10 minutes goes DEAD and after restarting says can not write to com port 7
I use 4 port HUB not powered.

With cgminer there is a big problem to make it working.

I use it on windows so is there any advice what to do?
Frequency is 800Mhz

Ok that's recent this warning, i don't see it this week.

But there are a big problem with the gridseed G-Blade.

The only soft which is 100% compatible is fork from jmordica, all other have bug because G-Blade have 40 chip and not 5
 

I try to patch bfgminer to support 40 chip but i'm not good programmer and my patch don't work very well, pool detect 7,8Mh/s against 10,6Mh/s with the jmordica fork of cgminer.

And you read the warnings


Popular cgminer 3.7.2 is not supported due to the bug in the code. You have to use newer miner. Read FAQ to learn more about it.

When there pool switch to currency i have the problem.

What pool are you getting this error on?
I will see if I can point my blades at it and see if I get the same issues

hi jmordica,

I have a problem with your cgminer with my G-Blade Gridseed (40 chip on board) .

On only one autoswitch pool (not all), when it switch to currency, all shares are reject with this error message:
share is above target rejected

I try to modify diff but i have the same problem.
To solve the problem i must switch to backup pool and when I switch again to the autoswitch pool, that works very fine until pool switch to currency.

Have you an idea to solve the problem ?

Here is the compiled cgminer for Raspberry Pi that supports Gridseed: http://0c31ac7857e819701732-7c102875f448c5383a11c1d07426cb3e.r86.cf1.rackcdn.com/cgminer

Here is the source: https://github.com/jmordica/cgminer-gc3355

chips=40 for blade and chips=5 for 5-chip.

So, question, the cgminer 3.7.2 that works in windows for the gblade.
The HW count, is that diff1 count or vardiff HW count?

Yes i know that this is on this thread and others BUT
it can get confusing for some of us OLD gits
so i thought i would do it command by command


ok heres what i did
make sure you are sudo su to root
cd   
apt-get install build-essential libtool libcurl4-openssl-dev libncurses5-dev libudev-dev autoconf automake screen
wget http://curl.haxx.se/download/curl-7.34.0.tar.bz2
wget http://www.digip.org/jansson/releases/jansson-2.5.tar.bz2
tar -xvf curl-7.34.0.tar.bz2
cd curl-7.34.0
./configure
make
make install
cd ..

tar -xvf jansson-2.5.tar.bz2
cd jansson-2.5
./configure
make
make install
wget http://ftp.osuosl.org/pub/ubuntu/pool/main/a/automake1.11/automake1.11_1.11.6-2_all.deb
sudo dpkg -i automake1.11_1.11.6-2_all.deb
sudo ln -s /usr/local/lib/libjansson.* /usr/lib/
cd ..
git clone https://github.com/jmordica/cgminer-gc3355
if you have a problem with git then use  'apt-get install git'
cd cgminer-gc3355/
./configure --enable-scrypt --enable-gridseed
make

Thats it your done
./cgminer --gridseed-options=baud=115200,freq=800,chips=40,modules=1,usefifo=0,btc=0 --hotplug=0


this works on Ubuntu 13.10  and the new version 14 Ubuntu

Hope this helps someone out.

Hi Gus
i just built my self a new linux box to run my 3 blades
and i have install ubuntu 13.10

i have installed cgminer and it runs the blades but i not get the top information on the screen all i  get is this
