[U-Boot-Users] U-Boot and S3c2410

Howdy Dave,
tftp 0x30800000 initrd (I'm using a ramdisk)
tftp 0x33000000 uImage
bootm
The Mizi kernel is expecting the compressed kernel image to be located
at 0x30f00000. I would need to verify where this came from, but I've
been using it this way for a while.
Also, be sure you have your serial port access configured the same in
both U-Boot and the Mizi kernel. I have had problems in the past (don't
remember exact details) that were related to having the kernel and
U-boot set to different Baud rates. I believe this is talked about in
the U-boot documentation some-where, or has been discussed on this list.
