Hi all, I tried to migrate u-boot-1.1.3 on my Samsung S3C44B0X based evaluation board and my target was booting uClinux with U-Boot. Several days ago I could see the serial port output and the user input prompt in minicom at last. Then I configured and compiled the uClinux-dist-20040408 on the Fedora Core 4 platform. As a result, I got an 826KB zImage binary file(As far as I know, the zImage consists of a Linux kernel image and a ramdisk image.) in the uClinux-dist/images/ directory. I downloaded it into the Flash memory(Intel 28F320C3B) using a flash programmer application on the Windows XP platform. But I've tried to boot the zImage using "bootm" commands several times but all failed. U-Boot always prompted "Bad Magic Number" error. So I wonder how to boot zImage in Flash memory in my case. Besides, I still have some questions about the migration. For instance, I don't know the meaning of "CONFIG_BOOTFILE" when I referred to include/configs/B2.h. And I don't know how to configure my "CONFIG_BOOTARGS" correctly. And the distinction between "CONFIG_BOOTARGS" and "Environment Variables" since I am not familiar with the booting of Linux. Sorry for my poor English and any advice would be appreciated.
