Evaluation Type: Independent Products
Did you receive all parts the manufacturer stated would be included in the package?: True
What other parts do you consider comparable to this product?: Banana pro
What were the biggest problems encountered?: 1)Getting the correct offset for the overscan values. 2)The difference in physical numbering and BCM numbering of the GPIO put forth some trouble at the beginning.
The brand new version 2.0 of raspberry PI announced on 5 Feb,2015 is making some noise every where in the SBC community. So let’s see what it’s all about.
My review will cover the following parts
2) potential issues
3)Starting up the pi
5)What are other options
The ultra-low-cost,cards sized Linux computer has had yet another makeover, this time the The Raspberry Pi 2 Model B is on a completely new level to its predecessors by being a staggering 6x faster than the Raspberry Pi Model B+. Also due to the same footprint as Rev 1.0 , it's conveniently compatible with all B+ accessories. Some of it's enhanced features compared with previous generation are as follows :
2) Potential Issues
Some of the potential issues with that Board are as follows :
I did not have a spare hdmi display or the one with RCA , so I decided to install it in a headless mode so i will put up instruction on how i went about doing it.
SD card reader
A computer connected to internet
1. Download and prepare NOOBS on a sufficiently large SD card, 4 GB or greater.
(This includes formatting the sd and copy pasting the noobs files inside the sd)
2. In the
os folder on the SD card with NOOBS, delete all folders except
Raspbian (This include folders like
Data_Partition if any of them are present
\os\Raspbian\flavours.json, so it only contains the desired version of Raspbian, "Raspbian" (not "Raspbian - Boot to Scratch").
root) to insert
silentinstallto the arguments list.
runinstaller quiet vt.cur_default=1 coherent_pool=6M elevator=deadline
runinstaller quiet vt.cur_default=1 coherent_pool=6M elevator=deadline silentinstall
5. Insert the Sdcard into the pi. Power the Raspberry Pi on to start the installation. And wait! This can take a while, like half an hour or more.
1. Insert the sd back into your pc and
cmdline.txt (in folder
boot off the root of the SD card) add this at the end of the long line:
The end result may be something like:
dwc_otg.lpm_enable=0 console=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p6 rootfstype=ext4 elevator=deadline rootwait ip=ip=169.254.0.2
Save the file and remove the sd card insert it into pi and power it up.
Connect Rpi and your PC using an ethernet cable . Your PC should detect the new network.
2(For windows only). Download and run putty from Download PuTTY - a free SSH and telnet client for Windows
2(forlinux) linux already has a SSH client so no need to download any additional files
3.In Putty configuration find Connection-->SSH-->X11 and tick X11 forwarding
4.Entern the session settings of putty and enter the ip address that you had inserted in the step 1 above (192.168.1.69 is displayed in the pic)
And then select save and give all this settings a name.
If all goes well you should be prompted to type the username and password (ignore the first warning by clicking yes)
5.Congratulation you have setup your pi in a headless installation.
the display in black background and white text is the terminal access. type in any command you want in it such as raspi-config
or type in the name of a program such as scratch and you will get a new window with the program running in it
Raspberry Pi 2 essentially solves the biggest problem that limited past hardware by adopting a quad-core processor. These changes offer greater capabilities, while still keeping the same form factor, the same price point and backward compatibility with the existing Raspberry Pi. It also starts up much faster than older versions, and feels much more responsive to user input than before. It'll definitely make the company’s target of three million units shipped this year eminently achievable.The Raspberry Pi 2 is no match for cutting-edge PCs, but the fact that it remains at a price point of about $35/£25 makes it possibly the best value computing device around.
5)What are other options
After the emergence of the first SBC, several others have appeared in the community some of the very interesting ones with notable difference with pi2 are listed below
*Orange pi: Has onboard 8GB EMMC Flash, Onboard WIFI,IR receiver, slot for SATA drive @ $ 59.00
*Odroid-C1 1.5Ghz quad core CPU , Infrared(IR) Receiver @ $35.00
6)My Project with pi
I plan to make a multimeter(a cheaper alternative to fluke multimeter or so) with logging capabilities and to produce graphical data about the variation in the input value and uploading the result to a server finally obtaining a graphical representation of the variation
Im halfway through the project and will post it at element14 forum latter.
