S3C44B0X Demo Project
(By IAR EWARM v4.30)

Hardware:
- Fin=8MHz, Fout=50MHz;
- SDRAM=32MB (0C000000 ~ 0DFFFFFF)
- FLASH=2MB  (00000000 ~ 01FFFFFF)

Project Configurations:
- RAM: All code and data are loaded to RAM by an emulator (e.g. J-Link), then run in RAM
- FLASH_NOXIP: Boot from FLASH and self-copy all code and data to RAM, then run in RAM

Man-Machine Interface:
- UART0 of S3C44B0X
- HyperTerminal of PC: 115200bps, 8 data bits, 1 stop bits, no parity, no flow control

Menu Description:
- Set Download Address: When receiving a file, save it to which address
- YModem Download: Wait for and receive a file from PC through serial port
- Program Boot Flash: Program a block of data from RAM to FLASH (M29W160B)
- Load To RAM: Copy a block of data from FLASH to RAM
- Jump To: Set the Program Pointer (PC) of S3C44B0X to a specified address

How to Use:
- Build the "FLASH_NOXIP" configuration and get the file "44b0.bin"
- Load and run the "RAM" configuration by an emulator (e.g. J-Link)
- Use "Ymodem Download" to download "44b0.bin" to RAM (0d000000 by default)
- Use "Program Boot Flash" to program "44b0.bin" to FLASH (00000000)
- Then the board can boot from FLASH and update itself without an emulator
