[U-Boot-Users] Regarding exception in UBOOT

[Dileep Kumar]

Hi,
I am analyzing code for uboot -1.1.6 . I have some doubts related to exception.
In the file "start.S" there is a term , TRAP FRAME , and stack pointer.
Could you please tell me what is trap frame? and where stack pointer points ?
If the stack pointer pointer points to a stack ( different from TRAP FRAME )
then what is the purpose of TRAP FRAME?
What are contents of TRAP FRAME?

Thanks
Dileep Kumar
