Porting uClinux 2.4 to S3C44B0X successful!

Now is Jul 30, 2009, 00:30.

Don't know how to express my happiness! I eventually had uClinux 2.4 booted on my S3C44B0X board! After two or three months trying and experiments, finally figured it out that all has to do with the toolchain used.

Following is the startup information:

Yet another thing proud of: I done finished all jobs in linux, except sometimes burning the bootloader after a serious failure.

Will post another detailed document the other day, now go to sleep! zzz~
