[U-Boot] Getting started with uboot

[Thomas Heller]

Thanks again for the help, it works now.

Next question:

'make uImage' in the linux kernel tree builds a linux kernel image
that u-boot can use.  How can I change the compression that is used?

Actually, I'm not even sure whether my kernel is compressed or not.
Here is the laat part of the output from 'make uImage'; it tells me
the kernel is not compressed:

>   UIMAGE  arch/arm/boot/uImage
> Image Name:   Linux-2.6.31
> Created:      Thu Aug  5 23:59:59 2010
> Image Type:   ARM Linux Kernel Image (uncompressed)
> Data Size:    1517292 Bytes = 1481.73 kB = 1.45 MB
> Load Address: 0x80008000
> Entry Point:  0x80008000
>   Image arch/arm/boot/uImage is ready

however the embedded system tells me it is uncompressing:
