Re: [U-Boot-Users] booting wince nk.nb0 on uboot (Shiju Mathew)
From: "Shiju Mathew" mshiju@gmail.com I have a pxa270 based board. We have both linux and wince running on the system. Right now we are using uboot to boot linux and
eboot
to boot wince. We want to use uboot to boot both linux and wince. I read a few post in this mailing list regarding wince booting and one of them
says that uboot
supports wince nk.nb0 format. I tried this format as below but just got a message "Starting application at 0xa0100000".
tftp 0xa0100000 NK.nb0 go 0xa0100000
Has anyone successful in booting wince images using uboot.
We use u-boot to boot a CE 5.0 image. I can't tell you what's wrong with your boot, but I can tell you it can be done. The commands are basically what you have - we use different addresses and filenames.
You do need to ensure that the image is loaded where it is built for - that means verify your config.bib is building the image for the address you are downloading to.
You don't need any special tools to create the .nb0 file, just an entry in config.bib to set the ROMSIZE.

Hi Tim, Thanks. I am new to wince and its configuration files. I modified the config.bib as you mentioned and I could create the NK.nb0 image. In config.bib the physical memory is mapped from 0x80000000(actual physical address 0xa0000000). So I change the address in the config.bib from 0x8xxxxxxx to 0xaxxxxxxx. The image with this modification did not worked in uboot (with eboot as well). I think this is not the right way to modify the address. Could you help me which all configuration files in wince has to be modified so that wince images could be booted on uboot.
Regards, Shiju
