Hello All,

           We are working on I.Mx233 processors and freescale provided B.S.P . As per the new requirement we have to upgrade the software through USB (previously we used SD card ).

Hence we have to implement all USB OTG diver in Bootloader ,

whether i.mx233 and freescale provided B.S.P will support for the same....?

Regards,

Hi kishore

in eboot one can download images to NAND with PB help, please

refer to attached WinCE Guide sect.5.5 Configuring USB Serial Connection

for Downloading and Debugging, sect.5.3.2 Burn EBOOT onto NAND flash using PB.

Otherwise one can use MFG Tools.

Best regards

igor

Hello igor,

   Problem with the our requirement is device will be fixed , we can't remove it for upgrade (If any update required) . Hence we are planning to implement USB OTG in the bootloader(whether it is possible in imx233 and win ce 6.0 ).

Regards,

Kishore P

Hi Kishore,

Why not boot a Linux for upgrade? I did it for many years, it's much easier than bootloader.
