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?
