Lab 1 启动

install Raspbian OS for Raspberry Pi

  1. Download an img file from https://www.raspberrypi.org/downloads

  2. Insert SD card and write the img file to the card.
    We can use terminal and enter instructions as follows:
    Notice: If your failed to write to your SD card with “dd” instruction, please check if you have permission to write to your SD card. If your permission is only reading, your can insert your SD card violently. More approaches to solve it: http://bbs.feng.com/read-htm-tid-3495425.html

Connect to Raspberry Pi with serial port

  1. The Serial Port on Raspberry Pi is shown as following:



    We can connect it as following(While – TXD; Green – RXD; Black – GND):


  2. Install a serial driver if you haven’t installed one. (downloaded from http://www.prolific.com.tw/)

    Find your serial port and install “screen” if it hasn’t been installed. 

    1
    2
    ls /dev/tty.*
    brew install screen

  3. Connect to your Raspberry

    1
    screen /dev/tty.usbserial 115200

Then you can see the infomation about booting of Raspberry as following:

Connect to Raspberry Pi with LAN

  1. Connect Raspberry Pi to router with cable and connect your Macbook to corresponding LAN.
  2. Test connection on Mac
  3. Connect to Raspberry
  4. Test connection on Raspbian

Cross compiling(on Ubuntu)

  1. Install compiler 

    1
    apt-get install gcc-arm-linux-gnueabi make ncurses-dev

  2. Write program

  3. Compile

    1
    arm-linux-gnueabi-gcc hello.c

  4. Send it to Raspberry

    1
    scp a.out pi@192.168.1.101:~/hello.out


5.Run the program on Raspberry Pi

Successfully!
