[GUIDE] GridSeed 5-Chip USB, Blade & Black Miner Support/Tuning

[maardein]

Hi guys,
    Anyone managed to run Gridseed 5 Chip with full hashrate for LTC (300kh/s) with reduced BTC rates?

    According to specs for GC3355 (per chip):

 160 BTC Units
 4 LTC Units
 BTC mode up to 2.25G/s BTCHashRate, with 2.4W/GHash
 LTC mode up to 60K/s LTC Hash Rate
 Due-Coin mode up to 1.75G/s BTCHash Rate + 60K/s LTC HashRate, or up to 2.25G/s BTC Hash Rate + 38K LTC HashRate

   Anyone?

I got around 250kh/s + 9Gh/s at 700 frequency when I tested dual mode on the controller.

[vertoe]

I did the port above, happy someone built a windows binary as I only run Linux myself.

would your fork compile on arch linux raspberry pi ?

I created gridseed aur packages for cgminer and cpuminer, if you run arch linux.
https://aur.archlinux.org/packages/?K=gridseed
They work on the raspberry pi (just tested).

Just modified the existing aur packages to use the gridseed git versions.
Contact me for feedback or any issues.

COMPLETE HOW-TO:
modify Scripta from Stock to automatically detect Gridseed GC3355 and show them in Web-Interface. ( No more ssh needed )

1. Download http://www.lateralfactory.com/download.php?file=scripta-1_1.tgz
2. Windows-User extract the .img-File and bring it to SD Card with http://sourceforge.net/projects/win32diskimager/
3. Boot Raspberry Pi with this SD Card
4. Detect IP Adress of Raspberry Pi in your Router
5. open ssh connection to port 7722 of that IP, user root, password scripta

6. Get modified cgminer

Code:

cd /opt/minepeon/bin

Code:

wget https://db.tt/UygLkqwd -O cgminer

7. Patch: Apply Gridseed Settings

Code:

nano /opt/minepeon/etc/miner.options.json

add here ( mind the { ... }, { ... } -Structure! )

{
 "key": "gridseed-options",
 "value": "baud=115200,freq=850,chips=5"
},

press Ctrl + o , Return, Ctrl + x to save changes

8. Patch: Allow Numbers as Password

Code:

 nano /var/www/f_settings.php

correct around line 60 to.. ( we remove “| JSON_NUMERIC_CHECK” )

file_put_contents($configPools, json_encode($newdata, JSON_PRETTY_PRINT));

press Ctrl + o , Return, Ctrl + x to save changes

9. Patch: More Stability for Raspberry Pi

Code:

nano /boot/cmdline.txt

add the parameter

Code:

 slub_debug=FP

( no new line! )
press Ctrl + o , Return, Ctrl + x to save changes

10. Patch: Graphs to be created by root

Code:

crontab -e

insert here:

0,5,10,15,20,25,30,35,40,45,50,55 * * * *  /usr/bin/php5 /opt/minepeon/etc/cron.d/5min/ALERTdeviceCount
0,5,10,15,20,25,30,35,40,45,50,55 * * * *  /usr/bin/php5 /opt/minepeon/etc/cron.d/5min/ALERThashrate

STEP BY STEP RASPBERRY SCRIPTA INSTALLATION

Step by Step Raspberry SCRIPTA Installation:

• 1 - SD Formatter (link) clean up your SD Card. At least a 4GB SD.
• 2 - Download the SCRIPTA Image (link)
• 3 - Win 32 Disk Imager (link) and write the scripta image on the SD Card.
• 4 - Put the SD Card into your Raspberry.
• 5 - SSH access on port 7722, user: root / psw: scripta
• 6 - Use WinSCP (link) to move over the latest rasp cgminer for gridseed (https://db.tt/UygLkqwd) or Use PuTTY (link)

Code:

wget https://db.tt/UygLkqwd -O cgminer

• 7 - Go to the location where you copied over your cgminer and do "chmod 777 cgminer"
• 8 - Go to the SCRIPTA Web GUI, under Miner hit Miner commands, STOP
• 9 - Go to the location where you copied over your cgminer and run it from there using these commands:

Code:

./cgminer --scrypt -o <miningpooladdress:port> -u <user> -p <pw> --gridseed-options=baud=115200,freq=850

Stability-Fix:

Code:

sudo nano /boot/cmdline.txt

Add the following code at the end of the first line (on the same line as the other text, DO NOT add new line!)

Code:

slub_debug=FP

How to get Scripta working as it was intended

Follow the instructions by Darkfriend77 below but when you get to step 6, go to directory opt/minepeon/bin and remove the original cgminer there (rm cgminer). Now copy the new cgminer into this folder to replace the original and chmod it as below.
Now go to directory opt/minepeon/startup and edit the file miner-start.sh with nano.
Change the line -

Code:

sudo /usr/bin/screen -dmS cgminer /opt/minepeon/bin/cgminer -c /opt/minepeon/etc/miner.conf

to

Code:

sudo /usr/bin/screen -dmS cgminer /opt/minepeon/bin/cgminer --scrypt --no-submit-stale --gridseed-options=baud=115200,freq=850 -c /opt/minepeon/etc/miner.conf

Lastly apply the stability fix.
Now you can close ssh and restart your pi and it should automatically fire up your gridseeds and start mining.

BUILD CGMINER ON THE RASPBERRY

referenced from litecointalk

build your CGMiner on the raspberry

Something like this:

Do a quick update just in case.

Code:

sudo apt-get update

Get dependencies if you already havent.

Code:

sudo apt-get install build-essential autoconf automake libtool pkg-config libcurl4-gnutls-dev 
sudo apt-get install libjansson-dev uthash-dev libncurses5-dev libudev-dev libusb-1.0-0-dev libevent-dev

Clone the Repo:

Code:

git clone https://github.com/dtbartle/cgminer-gc3355.git

Move into the directory, configure, and make the binary.

Code:

cd cgminer-gc3355
./configure CFLAGS="-O3" --enable-scrypt --enable-gridseed
make

Now you should see a cgminer file which was complied.  You may need to make it executable via:

Code:

chmod +x cgminer

Then run this cgminer however you'd like.

ROOT ACCESS TO LIGHTNINGASIC CONTROLLER

Ok, I will post this here, since I think people could benefit from it. I'll have to give most of the credits to Girhes, since he told me about the failsafe mode of openWRT, and assisted me while trying to gain access (he did not have a controller himself yet).

Please note that this is at YOUR OWN RISK, you could brick your device when you have root access to the controller. Please do NOT install any programs when you have root access, unless you really know what you are doing. There is almost no room left on the device, so installing a program could brick your device.

1 - Start the controller in failsafe mode:

There are different HW versions of the TL-WR703N - on version 1.6 you have to power on the controller, wait until the led starts flashing twice a second (it takes about 4 seconds to get there), then push the reset button immediately. When the led starts to flash much faster your device is in failsafe mode. All other HW versions: power on the controller, wait 10-12 seconds until the led starts flashing, then immediately push the reset button for 1-2 seconds. Again, if the led will start blinking rapidly you are in failsafe mode.

The versioin of your device is stated on the back of the device, underneath the barcode.

2 - Telnet into the device:

On windows go to start, type 'cmd' in the search bar, and start 'cmd.exe'. In the command window you get afterwards, type 'telnet 192.168.1.1'. Make sure you use the correct IP, my device used 192.168.1.1 in failsafe mode.

There is no user/pass required in failsafe mode.

3 - Switch to the live partition:

Type 'mount_root'

Warning! You are in the live partition now, with root permissions. You could seriously fuck thing up now!

4 - Change the root password:

Type 'passwd', and enter the password you would like (twice).

5 - Enable SSH:

Type 'vim /etc/config/dropbear', this will open the SSH config file in the vim text editor. You need to change "option enable" to "on".

You can start editing the file by hitting the 'i' key. You can now insert/delete characters. After you are finished editing hit the 'esc' key to stop editing. Now hit the ':' key, and type 'wq'. This will write the file, and quit the editor. If you made mistakes while editing, and just want to quit (without writing the file), type 'q' instead of 'wq'.

6 - Reboot the device:

Just unplug the usb power, and plug it in again.

7 - Have fun!

You can now SSH into the device while it is running in normal mode. (user: root, password whatever you entered in step 4). Just be carefull not to mess things up. If you are not at least a little familiar with linux, please be very carefull.

UBUNTU/LINUX INSTALLATION GUIDE

Hi Scrypt miners,

I was lucky enough to get one of the first Scrypt ASICs produced by Chinese GridSeed during my stay in South Korea last month. Cheers to Dis Btopia of xbitcoinx.com! I just hooked up one unit containing 5 chips to my Ubuntu box via USB port and here is what I did to get it running. Mind you, these instructions are for mining Scrypt, not SHA256 or dual mode, which the ASIC can also do. Most of the information I pieced together from this post in Chinese: http://cybtc.com/article-468-1.html

Download GridSeed's modified cpuminer and unpack zip file:

Code:

wget https://github.com/gridseed/cpuminer/archive/master.zip
unzip master.zip
cd cpuminer-master

..or download via git:

Code:

git clone git@github.com:gridseed/cpuminer.git
cd cpuminer

Install automake:

Code:

sudo apt-get install automake

You might need to install other compiling tools. I didn't need to, because I compiled other things before.

Compile:

Code:

./autogen.sh
./configure CFLAGS="-O3"
make

Connect and power up ASIC.

Find correct USB device:

Code:

ls /dev/*USB*

..or watch syslog while plugging in ASIC:

Code:

tail -f /var/log/syslog

Start mining (replace "ttyUSB0" with device found above and add your pool data):

Code:

sudo ./minerd --freq=600 --gc3355=/dev/ttyUSB0 --url=<your pool> --userpass=user:pass

You should now see lots of output with yellow "LTC" lines. If you see red lines, that's bad. Anyway, post here if you run into troubles.

I am not quite sure what the green and red LEDs are about. As far as I can tell there is no English documentation about that anywhere. I assume green (which is on as soon as power and USB are connected) indicates a certain ready state and red (which flashes sometimes) means hardware errors.

I am getting a lot of "Invalid nonce" errors in the cpuminer output along with red LED flashing. Probably because by mistake I got a 12V/0.5A power supply instead of 12V/5A and chips run low on power. So I can't tell you much about hash rates etc. right now. I'll get another power supply next week, so stay tuned.

Nice work Manfred, BUT the problem is, it's not stable........RaspPi will crash with 20 of those gridseed units after an uncertain time........even if you modifiy cmdline.txt with slub_debug=FP....

Code:

smsc95xx 1-1.1:1.0 eth0: Failed to read reg index 0x00000114: -110

[suchmoon]

COMPLETE HOW-TO:

Good stuff. I modified /etc/rc.local to start a different cgminer, instead of replacing minepeon's version, but it's essentially the same. Now the question I have is how to make Scripta handle more than one instance of cgminer? My crude workaround was to copy /var/www contents into subfolders, e.g. /var/www/1, /var/www/2 etc, and change 4028 port number in PHP files. It kind of works, except charts don't update, and I would prefer all instances and miners on one page. Is there a better way?

Try Hashra controla 1.2.0
It detects all gridseeds automatically in the webconsole (even 20 of them) and runs a solid 7200 khs (also on remote pool) stable .

whats the best/most up to date raspi image for the lazy people?

[CartmanSPC]

Does Hashra controla run cgminer or cpuminer?

[usao]

Does Hashra controla run cgminer or cpuminer?

The original question contained the phrase "Lazy", which is why I replied in the first place.
I actually have no idea. It just has a web interface where you enter your pool, and MHZ speed and hit "Start".
That's about as lazy as it gets. Right up my alley.

[miner765]

Is it only me that hashra controlla shows 7.2mh/s and pool shows around 6-6.5?

[maxzilla]

What pool are you mining on? Gridseed chips are at their best when you set the pool difficulty to 64. Most pools allows you to hint the difficulty (wafflepool put d=64 as password)

Scryptguild. Will try setting difficulty to 64, had it on 256.

They are ok at high difficulties too, even middlecoin with 1024 is fine. Only short term variance might be affected.

Wafflepool's "d=" doesn't go below 512.

[toxic0n]

Anyone know how to setup IP Tables on the Scripta image to avoid the client.reconnect attack?

I put up a mining guide for other who want to connect to DirectPool

agreed. i have 60 gridseeds. 20 to every pi on 10 port usb hubs. installed it yesterday and ran 24 hours nice and smooth on Coinmine.pw.

Hey,

I'm new to mining but I keep getting this in my feed.  Is this normal or am I doing something wrong?

https://www.dropbox.com/s/7jw5kdibooeefpl/workupdate.png

Any help is appreciated. Thanks.

[anarchyx914]

Has anyone managed to compile CGMiner and get it to run stable for 24 hours? I am running about 20 gridseeds, but when I compile CGMiner as per instructions my system crashes after a few hours of mining, giving these messages:

SendWork usb write err:(-7) LIBUSB_ERROR_TIMEOUT

When I use the pre-compiled version, I dont get this error. I really want to use the manually compiled version so I can see the device IDs and tweak each device individually, the pre-compiled version does not show device IDs for me for some reason ;((

Having 0 accepted shares in 45 mins is not normal.
Im using cgminer on 5x GSDs which have been running non-stop for 3.5 days.

As you can see from the pix, im getting plenty of accepted shares...
