Re: [U-Boot-Users] u-boot support for winCE on OSK board
Hi Naveen!
Hi,
Does the u-boot supports winCE?
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.
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-cmdbi...
But it is not working on my OSK board. Could any one suggest how to do it myself.
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?

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?

Hi Naveen,
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.
In my experience it's preatty hard to have a patch that works "out of the box"! ;-)
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".
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 i got the same error.
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..]
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?
Sorry.. I cannot help you here! :-)
