Experience in learning to build a test environment for the S3C6410 development board

This chapter only introduces how to install Android on the OK6410-A development board. Of course, we can also choose other development boards, and we can also test the Linux driver directly on the mobile phone. Since the methods of installing Android on different development boards and mobile phones are different, this is just a reference.

1 Install serial port debugging tool: minicom

Taking Ubuntu Linux as an example, you need to follow the steps below to install, configure, and debug minicom:

Step 1: Check whether the current system supports USB to serial port

#lsmod | grep usbserial If usbserial is found, it means the system supports USB to serial port

Step 2: Install minicom

#apt-get install minicom

Step 3: Configure minicom

#minicom -s Enter the configuration page, enter the "Serial port setup" menu item, configure the serial port device and transmission rate: Serial Device is set to /dev/ttyS0, Bps/Par/Bits is set to 115200 8N1, after the settings are completed, select "Save setup as dfl" and "Exit from Minicom"

Step 4: Test minicom

#minicom Restarting minicom will put it into the state of waiting to receive data.

2Burn the Android system

(1) Before burning Android, be sure to start EBOOT to erase NandFlash. The steps to use EBOOT to erase are as follows:

Step 1: Preparation

Connect the development board and PC with a serial cable or USB to serial port, and start minicom

Step 2: Enter Eboot state

Turn on the power switch of the development board. When the message "Initiating launch in 5 seconds" is displayed, press the space bar on the PC keyboard to put the development board in Eboot state.

Step 3: Erase NandFlash Enter "A" to erase NandFlash

(2) Steps for flashing Android

Step 1: Partition the SD card and format the partitions

Step 2: Write mmc.bin and zImage-sd.bin to the SD card

Step 3: Copy android_fs.tar, mmc.bin and zImage to the SD card and set the startup switch of the development board.

Step 4: Flash Android from SD card

Step 5: Calibrate the screen

3 Configure the wired network Since Android is essentially a Linux system, you can use the Linux command ifconfig to set the IP mask and subnet mask, and use the rout command to set the gateway.
