I want to boot the Windows CE image from SD card on i.MX53QSB,but the system can't run.

[LiMiao]

Hello：
   I want to boot the Windows CE image from SD card on i.MX53QSB。I use  these command to download the device.

cfimager -a -imx53 -d g -f D:\WINCE700\OSDesigns\iMX53_QSB\RelDir\Freescale_i_MX53_QSB_ARMV7_Release\eboot.nb0

cfimager -a -imx53 -d g -f D:\WINCE700\OSDesigns\iMX53_QSB\RelDir\Freescale_i_MX53_QSB_ARMV7_Release\nk.nb0.
--------------------------------
the size of   eboot.nb0   is 512kb, the size of   NK.nb0  is 149MB.

The following messages are shown but the OS is not started. CE image boot remains the message "Download successful!  Jumping to image at 0x0 (physical   0x70200000).". How can I solve this problem?

Thanks!

I find the message“Jumping to image at 0x0 (physical 0x70200000)... ” is located at OEMLaunch() which is located at \WINCE700\platform\iMX53_QSB\src\BOOTLOADER\common\main.c.I wirte an instruction that KITLOutputDebugString("Ready to Launch\r\n") before Launch(PhysAddress).So that the Serial debugging information add "Ready to Launch\r\n" at the end of the line.I find Launch(PhysAddress) jump to startup.s(bootloader).but I don't know how to debug assembly.
