Compiler end and download uClinux to arm-board:

First configure IP between host and arm-board;

Second start tftpd32.exe and copy uclinux_rom.bin to Disktop;

Third input command:tftp 0x0c208000 at host terminal;

Fourth input command:bootm 0x0c208000 at host terminal.

Compile hello.c with arm-elf-gcc:

arm-elf-gcc -o hello hello.c - efl2flt

s3c44b0x configure nfs:

mount -t nfs -o nolock serverIP:/shareDir /mnt

that's all.

this is just a hello program! ha ha ...
