UBOOT boot to WINCE

B M

Hi All,

I would like to use Uboot to boot to the WINCE image (TI A8 BSP). Can anyone provide guidance to get Uboot working for the AM335x EVM?

Thanks!

Do you really need u-boot or EBOOT for WINCE?

I am currently using EBOOT, however I would like to use UBOOT as it has more features.

Follow the below guide for build and flashing.

This is pretty heavy on Linux references (as most Uboot actually is). Is there anything specific needed to boot to WinCE?

Its not available, I believe. You can use most of the commands from u-boot and there is not much of linux dependency other than for build.

Hi Renjith, Have you actually used uboot to boot to WinCE. Where is the boot location of WINCE?

BM,

I have tried this many times on different platforms. I generally use u-boot as a starting point for EBOOT or first level bootloader development. Once EBOOT is fully done, I'll switch completely to EBOOT.

You can jump to the start address of the EBOOT.NB0 file. The start address can be figured out from the map file or eboot.bib file.
