Android Deep explore Hal and Driver Development fifth chapter

Fifth Chapter
This chapter studies the test environment for building the s3c6410 Development Board, where the S3C6410 board is a low-power, cost-effective RISC processor from Samsung that is widely used and provides optimized hardware performance for 2.5G and 3G communication services, with built-in powerful hardware to accelerate Meet data broadband requirements in high-end service communications.

Build a test environment for the Development Board first install the Serial Debugging tool (Minicom), since the development of Linux drivers is different from Android applications and cannot be developed on Eclpse. The installation minicom steps are as follows:

1, check whether the current system supports USB to serial port

2, Installation minicom

#apt-git Install minicom

3, Configuration minicom

4. Test minicom

After performing the above steps, if the serial port or USB to serial cable is properly connected, and the power is plugged in and the switch is turned on, the minicom will be subject to the information sent from ok6410.

After the build is complete, we need to burn the Android system, ok6410 default installation winCE6.0, so you need to uninstall it first, then install Android, burn write before you start Eboot erase Nandflash, erase method as follows:

1. Preparation: Connect the Development Board or PC with a serial line or a serial cable and start

2. Enter Eboot Status: Initiating image launch in 5 seconds

3. Erase Nandflash
Then write the following steps:

1. Prepare for the SD card
2. Write Mmc.bin and Zimage-sd.bin to SD card

3. Prepare to burn the android before writing

4. Start burning Android from SD

5. Calibrate the screen

Finally, to configure the wired network, the Development Board and other devices to connect the common methods include serial cable, USB, Bluetooth, WiFi and network cable.

The fifth chapter only describes how to install Android on the ok6410-a, we can also choose other development boards, during the installation process, you need to read the official documentation to learn how to use.
