/* Custom vectors section with 512 byte alignment.
|
|
|
|
The default ChibiOS linker script aligns to 1024 bytes, because that is the worse
|
|
case alignment requirement for STM32 chips.
|
|
See https://forum.chibios.org/viewtopic.php?t=5554
|
|
|
|
However the sonix-keyboard-bootloader expects the ISR vector table to be at 0x200.
|
|
This is not possible if the alignment is 1024 bytes.
|
|
|
|
By adding this custom section with 512 byte alignment before the inclusion of
|
|
the rules.ld defaults, the linker will use this section for .vectors objects. */
