Raspberry Pi, or people call it Raspi, is a low cost mini computer. With the Raspberry Pi, people enable to explore computing and learn how to program in languages like Scratch and Python. It is like a normal computer, but a mini one. It is capable of doing everything like the normal PC can do, from browsing, and playing high definition video.
In this idea, I would like to share about the Raspberry Pi first run. Raspberry Pi is like a normal motherboard PC, but mini, without operating system and using SD card to store the operating system. So after we have a Raspberry Pi, we must install operating system into the SD card so we can do whatever we want like a normal PC.
The Components
To do the Raspberry Pi first run, we need several components:
- Raspberry Pi (I used Model B rev2)
- 5V phone charger
- TV/Monitor (with cable to connect it to Raspberry Pi, I used RCA cable)
- Keyboard
- SD Card (min. 2GB)
- Computer with SD card reader
- Some accessories like (LAN cable, internet connection, etc)
Selecting Raspberry Pi Operating System
Since the Raspberry Pi use ARM processor, it cannot run the same operating system like our computer. Instead it must run one of the operating systems that have been optimized and ported to the Raspberry Pi processor and hardware architecture. There are plenty of the Raspberry Pi operating system like Raspbian, Arch Linux, RetroPi, ect.
In this idea, I used Raspbian "Wheezy" operating system. This operating system is the standard operating system to run on the Raspberry Pi and has very good Integration with the Raspberry Pi's hardware. We can get the operating system at Raspbian official site.
Supporting Tools
To get this idea or our Raspberry Pi run smoothly for it's first run, we need some programs as supporting tools to transfer the image to SD SDFormatter and Win32DiskImager.
Getting Started
Once we have the formatter and imager. Insert the SD card into our computer card reader. Firstly, we format the SD card using SDFormatter. Actually we can use the default formatter in our computer, but sometime it doesn't format the SD card clearly.
After we format our SD card, then we extract the downloaded Raspbian "Wheezy" to get the image file. Because when we downloaded the file, it was the zip format.
Next, Run the Win32DiskImager and select our Raspbian "Wheezy" image file. Then select the SD card device drive (in this case my SD card on drive H:). Click "Write" and wait until the writing process is done.
While waiting, we can connect the Raspberry Pi to USB keyboard, mouse, monitor or TV.
First Boot
Once we have Raspbian "Wheezy" in our SD card, plug it into the Raspberry Pi's SD slot.
Connect the 5V phone charger to the Raspberry Pi and the we will see the boot sequence on our TV/Monitor (if not, check the connection between the Raspberry pi with the Monitor/TV). After the first boot, the Raspberry Pi will show the setup mode.
If this doesn't happen we can manually enter the setup mode while type the following command.
sudo raspi-config
In this setup we want to set:
- Expand the Filesystem
- Our new password (default username: pi and password: raspberry but it is optional)
- Set locale and time zone
- Enable Desktop boot (optionally)
After that, we can now reboot the Raspberry Pi and enter Raspbian "Wheezy" operating system with default username and password (if we didn't change the password) and we can configure the Raspberry Pi in the way we want to.
