Android Deep Exploration (Volume I) fifth chapter

S3C6410 is a low-power, cost-effective SC (reduced instruction set computer, introduced by Samsung,

Compact instruction set computer processor, which is based on the ARM11 kernel.

OK6410 Development Board with "core board + backplane" structure

Install serial debugging tool: Minicom

First step: Detect if the current system supports SB-turn serial port

Lsmod | grep usbserial

Step Two: Install Minicom

sudo apt-get install minicom

Step Three: Configure Minicom

sudo minicom-s

Entering the "Serial Port Setup" menu will display the submenu shown in-4. The reader needs to configure Minicomm as shown in 5-4

Fourth Step: Test minicom

sudo minicom

Connect and open the board to see if the information is output

Burn and write Android system

Attention:

Three images (Uboot-fs210.bin, zimage_gt818, android4.0-fs210.img), SD card boot maker all under Android 4.0 for Nandflash folder, you must use the

First guarantee to Ping, put U-boot-fs210.bin, zimage_gt818 android4.0-fs210.img into the/tftpboot directory

Make Nandflash SD card boot (if the hardware dial is 1000 to start the Development Board, you can go to the Uboot Setup interface, this step omitted)
