I use hyper terminal to load bf561-ezkit-2008R1 via the serial port

when I send the file uImage-bf561-ezkit-2008R1-RC8, which is downloaded from blackfin.uclinux.org

all things is ok, and I can see the uclinux welcome interface...

hyper terminal shows things like this:

ezkit>bootm 0x1000000

## Booting image at 01000000 ...

Image name: Linux-2.6.22.18-ADI-2008R1-svn

Image type: Blackfin Linux Kernel Image

Data size: 3356581 Bytes = 3.2 MB

Load address: 00001000

Entry point: 00140000

Verifying checksum ... OK

Uncompressing Kernel Image ... OK

Starting Kernel at = 140000

Linux version 2.6.22.18-ADI-2008R1-svn

...successfully boot the uclinux

However, if I use my own images compiled from uClinux-dist-2008R1-RC8 using default settings,it fails to boot.

the hyper terminal appear like this:

ezkit>bootm 0x1000000

## Booting image at 01000000 ...

Image name: Linux-2.6.22.18-ADI-2008R1-svn

Image type: Blackfin Linux Kernel Image

Data size: 3402574 Bytes = 3.2 MB

Load Address: 00001000

Entry Point: 0014c000

Verifying checksum ... OK

Uncompressing Kernel Image ... OK

Staring Kernel at = 14c000

and nothing will continue to appear...

the only difference I can see is Entry Point, one is 140000, the other is 14c000

but I have used the default setting to compile ,what cause the different entry point?

And how can I load my own compiled files successfully?

Best Regards,

It is pretty difficult to tell what the problem is until we get some life on the console.

Have a look at:

To see where things are dieing.
