STEP BY STEP RASPBERRY SCRIPTA INSTALLATION

Quote from: darkfriend77 on March 09, 2014, 02:23:07 PM

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 -u -p --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

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

Quote

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

Quote from: maardein on February 27, 2014, 01:08:41 PM

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:

Quote from: Girhes

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= --userpass=user:pass

You should now see lots of output with yellow "LTC" lines. If you see red lines, that's bad. Wink

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.
