Arnova 10g2

Well the team over at http://www.arctablet.com have manged to create an Android 4.0 Ice Cream Sandwich (ICS) for the old Arnova 10 G2 from the arctablet.com website.

“Android 4.0 Ice Cream Sandwich (ICS) on the Arnova 10 G2, it’s there, finally !
We have an improved an existing ICS firmware to add root, Google Play Store support, CWR Recovery, init.d like scripts, 2 GB storage space for apps and few bugs fixes to the Arnova 10 G2”

Please be aware that the  Arnova 10 G2 has limited resources, such as 512 MB of RAM and older version ARM chip and as such  is a bit too low to offer perfectly smooth ICS operation but is vast improvement over the gingerbread default O/S

Installing the new Android 4.0 Ice Cream Sandwich (ICS) on the Arnova 10 G2

You will need to go to the following website

Go to the Arctablet.com Website and read the install instructions and download the custom firmware update and rockchip flashing tool

Arnova-10-g2-android-ics-custom-firmware

You also need to read the following guide about using the rockchip flashing tool

Flashing-arnova-g2-rockchip-2918-rockchip-flashing-tool

If the above does not work then to get the Arnova 10g2 in to recovery mode take a read of the following blog

Booting-Your-Arnova-10-G2-Into-Recovery-Mode

When I first tried this on my Arnova 10 g2 after I got the formatting system on the Arnova screen with the little android it then went to a graphic of a circle with CUSTOM arctablet.com FIRMWARE and then nothing happened this was because I push the upgrade button and not the restore button on the rockchip flashing tool.

Checking the speed of your Raspberry Pi SD Card

April 21, 2013 3 comments

Note that if you do a  read/write test on volatile memory such as USB or SD Cards then you will lose the data on them.

Having just upgraded the SD card on my Raspberry Pi from 4Gb to a 16GB, I was shocked to find that I was now getting a blank screen when running the start x for a good five minutes before the Raspberry Pi desktop would appear.

So I decided to run a program called HD_Speed from the team over at SteelBytes it measures both sustained and burst data transfer rates of your hard disks, cd/dvd-roms, flash cards/sticks, floppys, etc. in a realtime graphical display

The 80KB utility does not require installation and runs with a click. Select the drive and hit start. The read/write results show up as a graph and also as real values.

Which can be downloaded from the following location – http://www.steelbytes.com/?mid=20

It turns out that even though the  SD card for the Raspberry Pi was larger than the my previous SD card it was also a lot slower so it looks like I have to purchase a new faster SD card.

Quickly Scan Directory Sizes and Find Big Files

April 14, 2013 1 comment

Today’s blog is about a useful bit of software called treesize that can quickly scan directory sizes and find big files so you can work out where all the space on your hard drive has gone, to quote the develops of treesize about the freeware version.

“TreeSize Free can be started from the context menu of a folder or drive and shows you the size of this folder, including its subfolders. Expand folders in an Explorer-like fashion and see the size of every subfolder. All results can also be drilled down to the file level. Scanning operations run in a thread, so you can already see results while TreeSize Free is working. The Explorer context menu is supported within TreeSize, as well as the usual drag & drop operations.”

Which can be downloaded from the following location

Also if you want even more information about your directory sizes Take a look at the advanced analysis and management functions of TreeSize Professional.

 

Reference Sheet for Raspberry Pi (Debian) Commands

April 7, 2013 1 comment

Working with Microsoft software everyday I some times find it hard remember which Linux command does what and in what context it does it in when working with my Raspberry Pi.

So after a quick look round the internet I found a great reference sheet from the team over at Flosswire (Jacob Peddicord) who has put a long list of Debian commands to one sheet of A4 which can be printed off and kept for easy reference.

Take a look at the following link for the reference sheet
