[U-Boot-Users] u-boot support for winCE on OSK board

[Naveen Atmakuri]

Hi,

Does the u-boot supports winCE?
If i have to support winCE using u-boot, how can i start my work?

I am using u-boot-1.1.2.
I downloaded a patch from the following location.

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

But it is not working on my OSK board. Could any one suggest how to do
it myself.

Thanks in advance,
Naveen

not officially at the moment (of course, Wolfgang correct me if I'm wrong.. ;-)

>If i have to support winCE using u-boot, how can i start my work?

from the patch below, for example (BTW.. I think it has been removed from 
the site now..)
it should be a good start point to boot WinCE .bin images.

This patch adds a u-boot command (bootwince) which can handle WinCE images.

What do you mean by "not working"?
Do you have patch problems, build problems or runtime problems? please give 
me more details
and maybe I can help you somehow..

IIRC you have to take care at least of loading address..

Wince? What's that?

The more we disagree, the more chance there is that at least  one  of
us is right.

Hi,

When I applied the patch to my u-boot sources, it gave me an error.
So i carried out the changes manually and compiled the u-boot.

Then i used the new u-boot as the bootloader. 
After downloading the NK.bin source on to the SDRAM using tftp, i gave
the following command.
# bootm 0x10000000

But it prompted that "Invalid file format".

Even i tried with the NK.bn0 which is a raw binary file in winCE, but
i got the same error.


On the same OSK board if i have to support the lcd display in the
u-boot itself what are the things that i have to take care?


Thanks in advance,
Naveen

Hi Naveen,

In my experience it's preatty hard to have a patch that works "out of the 
box"! ;-)

This is normal.. NK.bin it's not in "u-boot format" (required by bootm) you 
should use
bootwince command:

# bootwince 0x10000000

>Even i tried with the NK.bn0 which is a raw binary file in winCE, but

Same as above. NK.nb0 is a plain binary file, ready to be executed (with 
the only requirement
that it should be loaded at the right address).
You should just run WinCE from NK.nb0 by executing:

# go 0x10000000 [or whatever your address is..]

Sorry.. I cannot help you here! :-)

You just forget to add CFG_CMD_BIN to your board's CONFIG_COMMANDS 
definition. Try something like:

#define CONFIG_COMMANDS (CONFIG_CMD_DFL         |  CFG_CMD_BIN)

(or whatever is needed for you board). This should fix the "unknown 
command" problem.
