default location vectorjump.o using auto linker

Hi,

(second attempt. For some reason the text disappeared when i send the forum post.)

I need to redirect the interrupt vector table from 0x8000 to 0xA880 to get the custom bootloader working. With the help of the ST forum I found out how to redirect the interrupt vector table.

With the following command in the linker file I can place the code (vectorjump.o) below at location 0x8000.

+seg .const -b 0x8000 -k

Debug\vectorjump.o

#include ''main.h''

struct interrupt_vector {

u32 interrupt_instruction;

};

struct interrupt_vector const _jumptab[] = {

{START_CBL_INTERRUPT_VECTORS}, /* RESET */

{(START_INTERRUPT_VECTORS + 4)}, /* TRAP - Software interrupt */

{(START_INTERRUPT_VECTORS + 8)},

{(START_INTERRUPT_VECTORS + 12)},

{(START_INTERRUPT_VECTORS + 16)},

{(START_INTERRUPT_VECTORS + 20)},

{(START_INTERRUPT_VECTORS + 24)},

{(START_INTERRUPT_VECTORS + 28)},

{(START_INTERRUPT_VECTORS + 32)},

{(START_INTERRUPT_VECTORS + 36)},

{(START_INTERRUPT_VECTORS + 40)},

{(START_INTERRUPT_VECTORS + 44)},

{(START_INTERRUPT_VECTORS + 48)},

{(START_INTERRUPT_VECTORS + 52)},

{(START_INTERRUPT_VECTORS + 56)},

{(START_INTERRUPT_VECTORS + 60)},

{(START_INTERRUPT_VECTORS + 64)},

{(START_INTERRUPT_VECTORS + 68)},

{(START_INTERRUPT_VECTORS + 72)},

{(START_INTERRUPT_VECTORS + 76)},

{(START_INTERRUPT_VECTORS + 80)},

{(START_INTERRUPT_VECTORS + 84)},

{(START_INTERRUPT_VECTORS + 88)},

{(START_INTERRUPT_VECTORS + 92)},

{(START_INTERRUPT_VECTORS + 96)},

{(START_INTERRUPT_VECTORS + 100)},

{(START_INTERRUPT_VECTORS + 104)},

{(START_INTERRUPT_VECTORS + 108)},

{(START_INTERRUPT_VECTORS + 112)},

{(START_INTERRUPT_VECTORS + 116)},

{(START_INTERRUPT_VECTORS + 120)},

{(START_INTERRUPT_VECTORS + 124)},

};

To do this I need to alter manually the linker file.

Before this I always used the auto linker option

Project->settings-.linker->input-> auto

Is there a way to get the same result but with the auto linker?

Hi Hoek,
