I hope I'm not be heretical here, but can u-boot boot CE?

thx,

Probably, but I guess nobody cares about it ;-)

yes it can. Load your image into RAM and use the "go <address>" command

There is also a better way I'm currently working on (with good results for 
now!)
You can upload the .bin file (which is, usually, much smaller than .nb0 
file), parse it's content and create the
binary image into the ram.
I already posted some ideas on this to this list but it seems that there 
are not many people interested in
booting windoze systems with a Linux bootloader ;-) (preatty easy to guess 
their reasons! ;-)

On my own I have added a new command (called bootwince) which "execute" a 
.bin file (downloaded via TFTP or stored in flash), and
I also added some "Linux command line"-like parameter passing.
I don't know if it will be accepted into the u-boot official CVS, becase 
"stealing" a  command for such a reason is questionable
(what's your opinion about it Wolfgang?). Do someone knows a 
"better"  (acceptable ;-) way to do so?

Just for correctness: the "U" in U-Boot stands for "universal", which
includes the idea of supporting more than Linux.

bootwince = boot & wince when you see what's coming up? SCNR...

The patch (which has NOT been tested with the latest u-boot version, but 
should work anyway)
can be downloaded from the public section of our web site:

http://www.dave-tech.it/download/misc/sw/zefeer/zwck/u-boot-zwck-0.9.0-cmdbin.patch

any comment is welcome, of course! :-)

It should be ported with easy to different architecture (thanks to u-boot 
structure :-),
but you will need to adapt your WinCE OAL to support all the stuff (like 
command line).
This code (OAL dependent) is abstracted into a function (called 
'build_bin_image_parameters()')
that should be placed inside your board's source code.
It is architecture dependent only for PHYS_SDRAM_1 definition (my .bin file 
has the wrong physical offset...)
The code is preatty lame, so feel free to change it (and, of course, tell 
me your opinion about it!)

It has been tested with our ARM9 module (Cirrus EP9315 based) and WCE 5.0.
