(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?
