I use hyper terminal to load bf561-ezkit-2008R1 via the serial port
<meta content="text/html; charset=utf-8" http-equiv="CONTENT-TYPE" /> <title></title> <meta content="OpenOffice.org 2.4 (Linux)" name="GENERATOR" /> <style type="text/css"> <!-- @page { size: 21cm 29.7cm; margin: 2cm } P { margin-bottom: 0.21cm } --> </style>
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?

It is pretty difficult to tell what the problem is until we get some life on the console.
Have a look at:
https://docs.blackfin.uclinux.org/doku.php?id=post_mortem
To see where things are dieing.
