Hi,
    I found your "i.MX6 Platform SDK" from internet. It's very helpful for me. Now I meet problem with the code:

 

Q1: Why don't the code map the interrupt vector section to address 0x0000?
You just copy it to the tail of OCRAM. As we know, arm arch always fetchs interrupt vector from address 0x0000, of course including an offset.

 

Q2: In the assembly code source file cortexA9.s. I find that some functions don't have "push {reg-list}" & "pop {reg-list}" to save & restore context. Is it safe to call?
