Hi All,
 
I am trying to port a RTOS to OMAP3530 board. I use CCSv4 and XDS510 PP +
JTAG emulator  to connect to the board.
 
I am trying to set up vector table for a my custom RTOS.
 
ARM provides 0x0000:0000 and 0xFFFF:0000  as the Vector base address.
 
I planned to use 0x0000:0000 for my development. 
 
I have decided to hard-code the opcode for the corresponding branches  to
the loactions respectively.(0x00000000 to 0x0000001C)
 
When i write to 0x00000000 location , i get a prefetch abort exception. Why
am i not able to write to 0x00000000?
 
How did U boot handle this? How did U boot set  up Vector table?
 
Can anyone help me please?
 
 
 
 
Regards
Rahanesh
