Relocate vector table in TMS570LC4357.

Other Parts Discussed in Thread: TMS570LC4357

Hi,

I am using TMS570LC4357 to code bootloader and application.

I am placing bootloader Vector table @ address 0x00000000 and application vector table @ 0x00200000 and application code @ flash 1 0x00200020.

In debug mode the program work properly, jump to application was successful and interrupts in application code works properly. but in Run mode Interrupts in application code does not work properly.

I observed code working properly in run and debug mode when I changed application vector table to 0x00000000. But I want to shift application vector table to Flash1 @ 0x00200000.

If I shift application vector table to 0x00200000,in run mode interrupts are not working. how to resolve this. Please suggest.

1. How to relocate vector table?

Thanks

    You may get better answers over in the Hercules forum.


    As far as I know the Cortex-R5 interrupt vectors can be in one of only two places: 0 ("LO") and 0xFFFFF000 ("HI").  There's no interrupt vector pointer register.

    In your case the boot loader will have to have a passthrough mechanism, perhaps as simple as coding every vector (except Reset) as a branch to itself+0x200000.
