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
