Fifth chapter, build the test environment of s3c6410 Development Board

Through the study of this chapter, I have a certain understanding of the test environment of s3c6410 Development Board, and have mastered the following knowledge points:
First, for s3c6410 This development Board, it is a low-power, cost-effective processor, it is based on the ARM11 core.
The difference between different development boards is mainly in the way of burning embedded system.
Iii. steps to install the Serial debugging tool: Minicom steps
1, check whether the current environment supports USB to serial port
# Lsmod | grep usbserial
2, Installation minicom
# Apt-get Install minicom
3, Configuration minicom
# minicom-s
Go to the "Serial Port Setup" menu item, configure it as shown, and after Setup is complete, select "Save Setup as DFL" and "Exit from Minicom" in the configuration.
Note: If the reader PC has a serial port, you can directly use the serial cable, and the serial device is set to/DEV/TTYS0, if there is no serial port, but the use of the USB interface, it should be set to ttyusb0
4. Test minicom
# minicom
After executing this command, if the board has a system installed, minicom will be able to receive data from the Development Board, which will successfully install and configure the Minicom
Four, burn write an Android system to the Development Board
1. Erase Nandflash method
(1) Connect the Development Board and PC with serial cable or USB to serial cable, and start minicom;
(2) Enter Eboot state
(3) Erase Nandflash
2. Burn and write Android steps:
(1) Prepare a 2GB or 4GB SD card, require FTA32 partition format, insert card reader and connect pc
(2) Write minicom and Zimage-sd.bin files to SD card
(3) Preparation prior to burning and writing
First copy the Android_fs.tar, Mmc.bin and zimage files to the SD card and set it to boot from the SD card, and then use the Nandflash to start Android after the burn is completed.
(4) Start burning from SD card to write Android
Insert the SD card into the slot of the Development Board and set it to boot from SD card, open the Development Board, when the Development Board is entered when the # prompt appears. The YJSX command starts copying the data on the SD card onto the board, and if it eventually appears "great!!! All jobs are over "information when it is stated that the Android system was successfully installed on the Development Board.
(5) Calibration screen
Do not forget to close the board when the installation is complete, and then restore the switch to the Nandflash boot state.
