My kernel hanged in when passed the parameters to it, and I dump nothing from the log_buf, so I guss it is crashed at the very beginning. however I didn't know how to setup the KDB to load the kernel with the BDI2000 ethernet? is there anyone has even loaded and debugged the kernel with the BDI2000 ethernet? if so pls show me how it goes?  ,Thanks- Denny

You don't need KDB to use the BDI2000 to debug a linux kernel, in fact
you need nothing on the target side.  Simply attach the BDI to your
hardware, and use a (cross-)gdb with the "target remote
<ipaddr>:<port>" command.  Our DULG shows how to do that with
U-Boot[1].  Debugging (static) Linux is exactly the same...

Cheers
