loading linux using vxworks boot loader

Started by Sagar Borikar May 18, 2006
Hi ,

I am loading the kernel 2.6.12 for MIPS target using vxworks boot
loader.
VxWorks kernel 5.5.1 image is at 0x80010000 and I have linked the linux
ELF  image with the same start address in Makefile. And the
start_kernel with 0x80ae600 address.
As it is vxworks version is after 5.4 , it can identify ELF compatible
images.
VxWorks boot loader is able to identify start_kernel but then it throws
the exception mentioned below.
Any pointers?

Attached TCP/IP interface to macb0.
Attaching network interface lo0... done.
