[U-Boot-Users] at91rm9200-want to know about the 6th vector

[vibi]

hello,
        i am  beginner in this field.Now i am  working with at91rm9200 &
i want to develop a program to load data to sram of ar91rm9200.
    
    i want to know how do we set the 6th exception vector to contain the
size of program to be loaded in to sram.i came to know about this 6th
vector after going through at91rm9200 datasheet.
i have gone through u-boot code & i didnt see size in the 6th vector
instead it was a branch instruction.

looking forward for your reply  & thanks in advance....

regards,
vibi sreenivasan

Why reinvent the wheel.
Everything you need is in datflashboot.bin.
Contact your local Atmel representative to get source.
Wanted to include this in U-Boot distribution, but Wolfgang did not want it.
