There are plenty of people here that would help. However, you can't expect 'generic' help. You need to be specific about your problems. For example, most of us would have no idea what a s3c2410A is, sure we could find it with Google, but save us the trouble. ... ARM920T core. Getting a 'simple hello world' could mean you are trying to boot a processor from scratch and get hello world coming out the serial console, or it could mean you are writing a u-boot standalone application and can't get it to work. I'm assuming you've read through all the excellent docs on Denx's web site. Here's a copy of my U-Boot walk-thru's on a couple of PowerPC boards, and another on bare-metal experiments with gcc on an ARM 7TDMI core ... PowerPC stuff; http://www.ovro.caltech.edu/~dwh/powerpc_mpc8349e.pdf http://www.ovro.caltech.edu/~dwh/powerpc_440ep.pdf ARM stuff; http://www.ovro.caltech.edu/~dwh/ucos/project_AR1803.pdf http://www.ovro.caltech.edu/~dwh/ucos/ The PowerPC stuff has an example of a U-Boot standalone app, while the bare-metal stuff has blinking LEDs etc. Cheers Dave
