Re: migrating from uClinux to emdebian crush on a Xscale PXA270 board

And a few other things are not clear to me: I saw that uboot

there a kernel and a file system image which can be loaded with uboot? The
current bootloader is uboot and it would be really handy if emdebian crush
can be booted with uboot.

Emdebian just provides a rootfs, nor a bootloader, nor a kernel, nor
drivers, ...
For such things i would recommend you to take a look to openwrt
project as they look like to fullfill your requirements.
Emdebian should work fine with u-boot. u-boot is a totally independent cross-platform boot-loader. You just have to program the kernel in some flash memory and the rootfs in flash memory, and pass the appropriate memory addresses as parameters to the boot command (which I assume you are familiar with?).

u-boot loads the kernel into memory and executes it (and passes some kernel parameters), then u-boot's job is finished - the kernel takes the reins from that point onwards.
