[U-Boot] Problem booting uImage with u-boot

[Saeed Abdoli]

Hello
I am working on a project in which I need to boot a customized linux kernel
on my board. The board components are stm32f429 processor, 8Mbyte SDRAM and
32Mbyte flash memory which are connected to the processer via FMC. I've
booted u-boot on the internal flash of the processor and I've installed the
linux image (networking.uImage) which is provided by EMCRAFT using TFTP
successfully. Then I tried to build my own linux image by editing the
example provided by EMCRAFT (rootfs). But when I build the image and try to
boot it, the processor can not boot the image and it resets unexpectedly.
This is the message u-boot shows when trying to boot the image:
## Booting kernel from Legacy Image at d0007fc0 ...

After this message the processor resets.
Can you please tell me what is wrong?
